I launch Windows and get a black screen. When there is a black screen when you turn on the computer

Facebook

Sometimes, when loading the system, users encounter such an unpleasant problem as the appearance of a black screen on which only the mouse cursor is displayed. Thus, it is simply impossible to work with a PC. Let's look at the most effective ways to fix this problem in Windows 7.

Most often, a black screen appears after the Windows welcome window has been opened. In the vast majority of cases, this problem is caused by an incorrectly installed Windows update when some kind of failure occurred during installation. This makes it impossible to launch the explorer.exe system application ( "Windows Explorer"), which is responsible for displaying the graphical shell of the OS. Therefore, instead of a picture, you just see a black screen. But in some cases the problem may be caused by other reasons:

Damage to system files;
Viruses;
Conflict with installed applications or drivers;
Hardware faults.

We will explore options to resolve this issue.

Method 1: Restoring the OS from “Safe Mode”

The first method involves using "Command line", launched in "Safe Mode", to activate the explorer.exe application and then roll back the OS to a working state. This method can be used when the device has a restore point that was created before the black screen problem appeared.

First of all, you need to go to "Safe mode". To do this, restart the computer and when you turn it on again after the sound signal, hold down the button F8.

The system boot type selection shell will launch. First of all, try activating the Last Known Good Configuration by using the arrow keys to select the indicated option and press Enter. If the computer starts normally, then consider that your problem is solved.

But in most cases this does not help. Then in the boot type shell, select the option that requires activation "Safe Mode" with the support "Command line". Next click Enter.

The system will start, but only a window will open "Command line". Type into it:
After entering, click Enter.

The entered command activates "Conductor" and the graphical shell of the system will begin to display. But if you try to restart again, the problem will return, which means that you should roll back the system to a working state. To activate a tool that can perform this procedure, click "Start" and go to "All programs".

Open the folder "Standard".

In the list of tools that opens, select "System Restore".

The starting shell of the standard tool for resuscitating the OS is activated, where you should click "Further".

Then a window opens where you should select the point to which the rollback will be performed. We recommend using the most recent option, but which was certainly created before the problem with the black screen appeared. To expand your choice, check the box "Show others...". After highlighting the name of the optimal point, press "Further".

In the next window you only need to click "Ready".

A dialog box will open where you must confirm your intentions by clicking "Yes".

The rollback operation will begin. At this time, the PC will restart. After turning it on, the system should start in standard mode, and the problem with the black screen should disappear.

Method 2: Recovering OS files

But there are cases when the OS files are so badly damaged that the system does not boot even in "Safe Mode". It is also impossible to exclude the possibility that you simply may not have the required restore point on your PC. Then you should perform a more complex procedure to resuscitate the computer.

When you start your PC, go to the boot type selection window, as demonstrated in the previous method. But this time, choose from the items presented "Troubleshooting..." and press Enter.

The recovery environment window opens. Select from the list of tools "Command line".

The interface opens "Command line". In it, enter the following expression:
Be sure to click Enter.

The shell will start "Registry Editor". But you need to remember that its sections will not relate to the current OS, but to the recovery environment. Therefore, you need to additionally connect the registry hive of the Windows 7 that needs to be fixed. For this purpose in "Editor" select a section "HKEY_LOCAL_MACHINE".

After that press "File". In the list that opens, select "Load bush...".

The hive loading window opens. In it, go to the partition of the disk on which your operating system is located. Next, go sequentially to the directories "Windows", "System32" And "Config". If, for example, your OS is located on drive C, then the full path to go to should be as follows:
C:\Windows\system32\config

In the directory that opens, select the file called "SYSTEM" and press "Open".

"OK"

After this, a new partition will be created in the folder "HKEY_LOCAL_MACHINE". Now you need to open it.

In the directory that opens, select the folder "Setup". On the right side of the window, among the elements that appear, find the parameter "CmdLine" and click on it.

In the window that opens, enter the value in the field "cmd.exe" without quotes, then click "OK".

Now go to the parameter properties window "SetupType" by clicking on the corresponding element.

In the window that opens, replace the current value in the field with "2" without quotes and click "OK".

After that, go back to the window "Registry Editor" to the section that you previously connected and select it.

Click "File" and select from the drop-down list "Unload the bush...".

A dialog box will open asking you to confirm your decision by clicking "Yes".

Then close the window "Registry Editor" And "Command line", thus returning to the main menu of the recovery environment. Click here on the button.

After rebooting the PC will automatically open "Command line". Enter the command there:
Click here Enter.

The computer will be checked for the integrity of the file structure. If violations are detected, the recovery procedure for the corresponding element is automatically activated.
Once the recovery is complete, enter the following command:
shutdown /r /t 0

Click Enter.

The computer will restart and turn on normally. It is important to take into account that if the system files were damaged, which caused the black screen, then it is quite possible that the root cause of this could be a virus infection of the PC. Therefore, immediately after restoring the computer’s functionality, check it with an anti-virus utility (not a standard anti-virus). For example, you can use Dr.Web CureIt.

If none of the above methods help, then in this case you can install Windows 7 on top of the working operating system while maintaining all settings, or completely reinstall the OS. If these actions do not produce results, there is a high probability that one of the computer’s hardware components has failed, for example, the hard drive. In this case, it is necessary to repair or replace the broken device.

The main reason why a black screen appears when the system boots into Windows 7 is an incorrectly installed update. This problem can be “treated” by rolling back the OS to a previously created point or performing a file recovery procedure. More radical actions also involve reinstalling the system or replacing elements of the computer hardware.

The appearance of a black screen when loading an operating system can, at a minimum, cause confusion for the user. What is the cause of the problem when a black screen appears when you turn on the computer? In this case, there seems to be a launch, but the image itself does not appear (nothing is shown on the monitor). In some cases, even the cursor is missing, there is no signal, and measures must be taken to quickly correct the situation.

Then how to remove the black screen on a work computer when no image appears on it when you turn it on? First of all, you need to understand what exactly is the cause of the malfunction. The reasons for such a breakdown include technical and software, but in 50% of cases the user himself is to blame due to his inattention, and sometimes simple lack of knowledge.

An example from life. A motherboard with a built-in video card was purchased. To increase performance in games, an additional external video card was purchased. When assembling the PC, everything was connected correctly and worked perfectly. Then, after cleaning or moving the system unit, the wires were disconnected and reconnected incorrectly. The wire from the monitor, instead of an external video card, turned out to be connected to the built-in one (VGA or DVI connectors are the same on all devices). Naturally, the PC was configured to work with an external video card and it simply wouldn’t start with the built-in one. Inattention or ignorance? Draw your own conclusions.

The technical reasons why the monitor does not turn on, the cursor is not visible and there are no standard boot messages are the following:

The PC is switched to mode for working with an external monitor (in this case, the lack of signal is relevant for laptops).
Malfunction of the cable (also a problem relevant only for laptops).
Video card malfunction.
The cable is connected to the wrong connector.
The cable that connects the system unit and the monitor comes off - again a black screen appears after booting.
The power to the monitor is turned off, so it does not start, nothing appears on the screen, not even the cursor.
Monitor malfunction.

Software malfunctions that lead to the monitor not turning on and a black screen appearing when the computer starts include:

The presence of a viral malware that prevents the computer from performing work. It is because of this that a black screen is shown on the monitor.
Inappropriate screen resolution.
The computer's video card has an incorrect update rate.
Incorrect operation of the OS loader or drivers.

Solving technical problems

To solve technical problems of how to remove a black screen, it would be wise to use the following action plan:

You need to make sure that the personal computer is turned on. To do this, check for the presence of working light signals and the sound of a working cooler. However, the cursor does not appear.
It checks whether the connection cables to the system unit, the power cables to the monitor are connected, and whether the button on the monitor is turned on.
If a black screen appears when you turn on the computer, check where the cable is connected to the socket. If necessary, you can reconnect the cable.
If your computer uses a built-in and external video card, you need to check which of these devices the monitor is connected to. You may need to switch the cord to a different socket.

Laptops almost always provide an output to connect an external monitor. If, when you start the laptop, you hear the sound of the coolers operating, which is accompanied by a black screen on the computer, then it is likely that the mode for working with external monitors was started on purpose or by accident. On the keyboard, you should find the function keys for controlling the operation of the external monitor and try to turn on the internal display.

The F7 key turns on/off the internal screen, and the F8 button controls the combination of output to the internal/external monitor of the laptop. They need to be pressed simultaneously with the function key, which is usually designated Fn.

Different operating modes are switched by successively pressing the following key combination: Fn and F8. When considering how to remove a black screen, you can try this method if the internal laptop monitor was accidentally turned off.

If you are sure that the black screen with a cursor is caused by technical problems, and the steps described above did not help you resolve the issue, there is still no signal, then you should contact a repair company or service center. In this case, you are unlikely to be able to fix the problem yourself.

Solving Software Crash Problems

If you encounter a black screen after turning on your computer due to malware or a software glitch, then it is recommended to follow these steps:

Try loading the operating system in safe mode. If you succeeded, then you need to continue to follow the steps below. If not, then the only option is to boot the operating system using external media.
When the operating system is loaded in safe mode, it is worth checking the refresh rate and screen resolution settings. If the computer monitor did not turn on before, then they need to be replaced with the correct ones.
Then the video card drivers are updated. Although safe mode is also used, this should be done using the device manager.
If the monitor on your computer has been turned on for a long time, then you need to launch an anti-virus program and carefully scan your PC for the possibility of infection with malicious software. Ruthlessly destroy all files that pose a threat.
After completing all the steps, the computer should be restarted.

When your monitor turns on, turns off immediately, or has a black screen after switching to a new monitor, you need to do the following:

The old monitor is connected to the computer.
The minimum screen resolution and refresh rate are set to 60 Hz. This is done in a special video card driver utility or in screen properties.
The computer is connected to the new monitor. Now you need to adjust the screen resolution and frequency for the new display.

There are times when, even if the computer is in full technical condition, the steps described above do not help resolve the question of what to do if the computer has a black screen. In this case, you can contact specialists. Some malware can only be detected manually, while antivirus programs will be useless.

Unusual reasons

What to do if the black screen is not caused by technical or software means? A black screen can appear due to the banal inattention of users, which sometimes reaches the point of absurdity. Before you start looking for complex causes of the problem, you should check your attentiveness:

Could you intentionally or accidentally lower the brightness of your monitor to a minimum? Then you can’t say that the monitor turned on for 2 seconds and went out, but the image itself was missing.
Do the metal parts of the PC “short”? Static electricity can get into your computer case. The device will start shutting down suddenly for the user, even while booting. This problem is often caused by touching the body of elements that conduct current, or by a large accumulation of dust inside the system unit.
It is worth listening to the sound of the cooler. Is the fan running or are there any unusual sounds? Often, due to a malfunction of the cooling system, the PC suddenly turns off. To avoid this problem, you need to keep your computer clean. It should not be leaned against cabinets or walls or placed near radiators.

The problem of a black screen appearing when you turn on the computer is solved by fixing a specific error. If you check the case for static voltage, increase the brightness or replace the cooler, the problem can be solved.

In any case, the appearance of a black screen should not lead the user to panic. In a fit of fear or bewilderment, you can only make the situation worse. You cannot knock on the system unit and monitor, this will not solve the problem, and may even completely damage the computer. It is also not recommended to disassemble the system unit yourself and switch the wires in it if you do not have experience in repairing it and you do not know the principle of operation of the computer.

I don’t want to be trivial, but the so-called “black screen problem” when loading the operating system after turning on the computer is one of the most common problems faced by owners of both desktop computers and laptops. An operating system that won't boot or a hard drive model doesn't really matter when diagnosing the problem. We will tell you further about how to remove the black screen when loading Windows 7 on a computer and laptop, and the reasons for the failure.

This guide will be updated, so do not hesitate to ask questions, I will clarify technical points as best I can and solve your problems with the black screen.

The most likely causes of a black screen on boot

First, you need to list the most common problems that cause a black screen, after which the operating system does not load (in other words, a black screen when you turn on the computer). In rare cases, after loading the user sees not only a black screen, but also a cursor. Causes:

There is a conflict in the operating system, due to which it cannot load the graphical environment normally.
Video driver problem (incompatibility with the current operating system: for example, Windows 10 or Windows 7, up to XP)
The hard drive on your computer or laptop has failed
Windows OS has crashed and does not boot correctly (not in safe mode)
Other hardware problems or system conflicts
Windows can't wake up from sleep state

Start Windows in Safe Mode on your computer

One of the most likely reasons why Windows or another operating system does not boot is a system conflict due to which the OS cannot work correctly after turning on the PC. This may be caused, for example, by the fact that the user installs an incompatible program or drivers that conflict with Windows, and when turning on the laptop/PC, the conflict will make itself known in an unpleasant way - in the form of a black screen. How can I remove it?

Fortunately, Windows developers have provided the ability to log into the operating system in a safe mode, which is designed specifically to eliminate various compatibility issues. By entering safe mode, you can fix all problems on your computer, resolve conflicts, and then boot Windows into normal mode.

So, to enter safe mode on your computer:

Remove from the computer all media and devices that may affect Windows boot (flash drives, disks, etc.)
Restart or turn on your computer, depending on its current state.
To enter Safe Mode, hold down the F8 key while booting. If your PC (laptop or desktop version) has several operating systems, then select the appropriate one from the list and then press F8 again to enter Windows Safe Boot Mode.

Problems with the monitor or components

The reason for the black screen may be obvious: the monitor is not working. This may be due to the fact that the contact between the monitor and the video card is lost or the power cable is damaged/not plugged into the outlet. So be sure to check your connection.

As for the laptop, it is unlikely that the matrix “fell off” from the motherboard. To disable it, you need good reasons: for example, mechanical impact on the display. In this case, you will see that there is obvious damage on the screen: scratches, dead pixels, etc.

In addition to the monitor, we recommend examining the system unit. Check whether the video card is secured in the corresponding socket on the motherboard and whether voltage is supplied to all PC components. This should only be done if you have the skills to assemble/disassemble a computer/laptop.

Resolving conflicts with the video driver, if the computer does not start, a black screen is displayed

An example of a similar problem:

Installed Windows 7, 10, restored to factory settings (native Windows image). But nothing helps. Simply put, when you turn on Windows 10 for the first time, everything is good and everything is fine, but when the drivers are installed on the video card (intel hd3000 and radeon 7600), flickering and a black screen occur, after which recovery and safe mode do not work. That is, Windows 10 dies, after installing the drivers there is a black screen.

If you think that the black screen problem may be due to a conflict of video card drivers on your computer or laptop, then:

In the Secure Boot menu, select "Enable low-resolution video mode."
After successfully logging into your operating system account through Device Manager or Control Panel, remove the conflicting ATI/NVIDIA video driver.
Restart your computer
There may be a conflict between the drivers of the motherboard and video card. You need to try different driver combinations. To avoid reinstalling Windows each time when experimenting, create a restore point and when a black screen appears, roll back to the previous restore point.
If the OS loads correctly in normal mode (the Desktop and Windows cursor appears), then the black screen problem is really related to incorrect behavior after installing the drivers. Go to the video card manufacturer's website and download the latest version to your hard drive again.
If the black screen continues to appear, try other solutions to the problem outlined in this guide - for example, uninstalling harmful programs.

We remove programs that conflict and block the OS from loading when turned on

Windows 7 does not start for me. When I turn on the computer, after the words “start Windows,” a black screen appears and the computer does not boot. There is no cursor. I restart the computer, I am given a choice of how to boot Windows, I select normal mode - and everything turns on, sometimes I need to restart several times. Normally it doesn’t turn on at all, I have CCleaner, I use it, the antivirus is Avast, I don’t update any drivers. What could be the problem?

In this case, the sequence of actions to fix the problem will be approximately the same as in the above case. The only thing is that in Windows Safe Mode you need to select the “Enable Safe Mode” option. Next, in this download mode, you need to go to the control panel and in the “Programs and Features” window, sort by application installation date. Analyze what you have installed recently: perhaps conflicting applications are the cause of the black screen and inadequate loading of Windows from the system drive on your computer. One of the best programs for uninstalling applications is the free CCleaner utility.

Disable unnecessary programs and services from Windows startup

There is a wonderful utility called msconfig, with its help you can speed up Windows boot. Although modern computers load the OS quickly, boot optimization can eliminate the black screen for a few seconds.

Start - Run. Enter msconfig in the window.
Services tab - here you can disable unnecessary services.
Startup tab - to enable/disable programs during startup.

In Windows 10, startup items can be disabled through the task manager (Startup tab). The status column displays the status of the application.

We use a restore point to perform a system rollback on the computer and fix problems on the computer

It happens that the cause of the OS failure cannot be identified; removing drivers and programs that cause conflicts does not help: a black screen still appears when the computer boots.

If the computer does not start, use the previous Windows restore point

We use a boot disk (Live CD) to fix errors and diagnose a black screen

When a black screen appears, it is advisable to check your computer and operating system for viruses. This can be done using a "live CD". We recommend using the 4MRescueKit boot disk to enter system recovery mode. In addition to the virus scan itself, livecd 4MRescueKit includes modules for data recovery, file backup, and a disk manager like PartitionMagic. Even if this does not help get rid of the black screen of death, you can at least prepare to reinstall the operating system or diagnose the performance of the hard drive in this mode. Live CD fixes problems regardless of the version: it can be both Windows and Linux.

The 4MRescueKit boot kit helps fix software errors on the disk

Black screen during Windows reinstallation

I get a black screen and a cursor, I reinstalled Windows and I still can’t completely reinstall it. After the first reboot, during the installation process, when loading Windows there is a black screen and cursor.

Solution to the problem.

Try using a different installation disk or version of Windows OS.
The reason for the appearance of a black screen and interrupted loading can be either software or hardware. For example, the hard drive contains bad sectors or the USB flash drive or the disk from which Windows is installed is damaged.
Try installing the operating system on a different partition of your hard drive.

Viruses have damaged Windows system files

Many computer viruses can delete or damage important system files. As a result, after loading Windows OS, a black screen appears, although the cursor can still be displayed and respond to your movements. Removing viruses does not always help solve the problem, but you can try.

How to check your hard drive for viruses if Windows won't boot? You need a working computer to which you can attach a hard drive. After booting into Windows, install the free Dr Web CureIt antivirus. The CureIt utility contains current virus databases.

Video instruction:

Select the hard drive to scan and launch the scanner.

If, after detecting viruses, a black screen still appears when loading Windows, then you need to look for other reasons.

Burn a recovery flash drive and reinstall Windows

After updating Windows 7 - black screen in any mode: normal, safe - no difference. I tried restoring Windows via the installation disk - to no avail.
Answer. Install Windows 7 from scratch or immediately install Windows 10, thereby killing two birds with one stone: update and solve the problem with the black screen when loading Windows 7.

One of the best programs for burning Windows to a USB flash drive is Rufus. The utility is available in Russian, it is free and, as a rule, burns trouble-free USB flash drives for installing Windows.

The worst thing that can happen: the hard drive fails

Finally, one of the most pessimistic outcomes. If you see a black screen and the cursor is still visible, then the hard drive is working. If there is nothing but a black screen and the OS does not load, then it is quite possible that the computer does not see the hard drive and, accordingly, Windows does not boot. By following the link you can read the manuals that will allow you to diagnose your hard drive and find out whether it is possible to make repairs, restore data by loading the operating system, or is it better to immediately go to the store and purchase a new HDD for your computer or laptop.

Summary. In this guide, I tried to remember and collect from the Internet the most complete list of problems that cause a black screen to appear on a PC. The OS version doesn't really matter, whether it's Windows 8, Windows 10, or the outdated XP. If none of the methods helped, something is unclear, or you have your own ways to solve this problem, please ask questions and add your ideas in the comments.

Answers to readers' questions

I have a black screen after loading Windows, I tried everything, but nothing helps: I turn on the computer - a black screen, and nothing can be done about it. The bottom line is that the black screen appears only after I update the drivers for the video card. If you install standard VGA, then everything starts and works fine.

Before this, I completely reinstalled Windows and it all started somehow unexpectedly with “nothing”. How to fix black screen when loading windows?

Answer. One of the surest ways to resolve OS and driver conflicts on your computer is to go to the website of the manufacturer of your video card and download the latest drivers or stable ones, not in beta, to disk. When downloading, make sure to specify your operating system in the same bit depth (32- or 64-bit). It is also possible that your video card is outdated and not supported by modern operating systems, in particular Windows 10.

If your laptop has a black screen, try updating the drivers

I have Windows 10 installed. An attempt to restore the OS from a system image failed. Now there is a black screen with a cursor flickering in the upper left corner when turned on. All I can do is turn on the computer and enter Bios.

Answer. If you only see a black screen and a cursor, this is a sure sign that the operating system cannot boot (you already understood the problem).

If the recovery console or Windows 10 installation disk does not help to roll back the OS to its original state or restore point, create either a new disk to restore or install the operating system from scratch.

Not a single folder opened, so I decided to run . A black screen with a cursor appeared on the laptop when turning on / starting Windows OS. I did everything according to your article, but the screen is still black. Help me please.

Answer. If a black screen appears when you start Windows even after recovery, it makes sense to reinstall the operating system on your laptop in another way - for example, in boot mode from a flash drive or disk. Since, according to your description of the problem, the cursor still appears on boot, this is a software error, not a hardware error.

An external box was connected via USB to format ext3 using PartitionMagic. After formatting was completed, the laptop restarted and there was no reboot, and a message appeared on the black screen: error loading operating system... The laptop no longer boots, does not respond to any keys... OS XP... what to do, it’s practically That's it, there is a 2nd PC with Windows 10. In other words, the laptop works - but the screen is black.

Answer. Luckily, your laptop is dealing with a software glitch and not a hardware failure. All you need is to reinstall the Windows operating system. After this, the black screen of death will no longer appear. If your laptop has a disk drive, use a boot disk to restore the OS. Otherwise, it will help you, it’s not difficult to write it down, read the instructions at the link.

I get a black screen when I turn on my computer. Nothing appears on the monitor when I turn on the computer and the system unit is running. I did one trick: pulled out the power, held down the power button for 5 seconds, released it, inserted the power cord, turned on the PC - everything worked fine. After 3 days the same thing happens, but this trick doesn't work. I think this is an incorrect shutdown. I turned it off the last time when some programs were still running (Windows 7 for me) and the Desktop did not appear after loading. What to do if your computer has a black screen?

Answer. You need to approach the problem comprehensively: figure out whether the motherboard and power supply are working correctly in general, whether all the wires are connected to exactly the right power connectors, whether the PC components are tightly connected to the sockets (for example, very often the “black screen of death” is associated with an incorrect connection video cards). Perhaps the problem is not hardware, but software (it’s just not clear from your question whether Windows boots). In this case, reinstalling from a boot disk or restoring in LiveCD mode will help.

Help me understand what's wrong with the PC. I have Windows 7. After the startup starts, a black screen and a cursor appear, then you are asked to select Windows 7 OS and the recommended boot or the normal one. After clicking them, the download starts and throws you back into the same settings. The same problem occurs with loading in safe mode. It does not offer anything further, there is no window for entering explorer.exe.

Answer. If, when you try to boot Windows 7, a black screen and the cursor continues to appear, no matter which mode you selected, most likely the Windows system files have been deleted or changed. A clean reinstallation of the OS or recovery from a Windows 7 boot disk will help. In the boot menu, select “System Restore” and then use the Bootrec.exe utility. Further actions are described.

I have an AMD Radeon video card with 512 MB of memory, it did not support new toys, and I found on the Internet how to increase the memory of the integrated video card via bios. I changed some settings in the BIOS and installed 1 GB of memory, my PC rebooted and I looked at the characteristics of the video card and yes, in fact, the memory has increased. Then I started playing games, about an hour passed and my mouse began to freeze, turn on and off, and then stopped working altogether, I decided to restart the PC and then on my monitor I saw just a black picture with some number in the corner. The computer refused to turn on, after probably half an hour of clicking on the mouse and keyboard, “welcome” appeared on the screen. The PC turned on, but the mouse still did not work, I rebooted again - and again there was a black screen for a very long time when the computer booted. What could this be and how can I get rid of it?

Answer. This is what overclocking a video card leads to. You need to go into the BIOS and reset the settings to factory (default) settings. Perhaps it is because of the BIOS settings that Windows does not start.

You're in luck: with such overclocking of a video card, problems with the temperature of the video card may arise, up to the failure of one of the components (for example, the processor).

In general, you can’t always trust such overclocking instructions. Even if it contains correct information, if you do not have the proper skills, you can get not only a black screen, but also black smoke from the system unit :).

I don’t know why it started, maybe after defragmenting the hard drive, or something like that. Every time, before Windows boots, a black screen is displayed for 10 minutes and only after that the welcome window appears. The BIOS definitely loads first, I pressed F2 to check the boot device priority in the BIOS. Also, during a black screen, the console carriage (lower slash) sometimes appears. What can cause a black screen when loading Windows?

Answer. In the BIOS, you can not only set boot priority, but also disable unnecessary devices (for example, a disk drive). However, this will not save the situation.

Perhaps the reason is that when Windows boots, it tries to find the required library or load a non-existent component. Go to the startup menu and disable all unnecessary items. You can also disable unused Windows services via msconfig and remove unnecessary applications on your computer. In general, it is desirable to optimize the operation of the operating system and eliminate conflicts.

You can also analyze the stages of Windows boot using the built-in Event Log Viewer tool. This utility will show how long it takes to load each process when the OS starts.

If time permits, reinstall the OS. On modern computers, reinstallation takes no more than half an hour, and this is a more rational way to solve the black screen problem than spending hours troubleshooting. Sooner or later, any Windows OS develops problems.

I have Windows 7 on my computer. Everything was fine, but one day after entering the bios password there was no Windows boot icon, and the monitor turned off (went into power-saving mode), the f8 key does not work. I can't enter bios because the monitor doesn't work.

Answer. Try resetting the BIOS by removing the battery from the motherboard.

Let's move on. The energy saving mode will not work immediately after the computer starts; rather, the problem is related to one of the components. Check the connection between the video card and the motherboard, the video card and the monitor, etc.

If everything is fine with the BIOS and Windows 7 does not boot, reinstall the OS. Apparently, this is the easiest method to get rid of the black screen.

Windows 7 32bit OS was installed. After changing to Windows 7 64bit, a black screen began to appear. When connected to the TV, everything works, everything is shown, everything is fine. But it doesn’t see through the VGA monitor and the screen is still black.

Answer. Perhaps the 64-bit version did not install drivers for the monitor or video card. Check on the manufacturer's website whether the monitor supports this OS. There is a suspicion that your specific VGA monitor is not supported by this edition of Windows. Try booting Windows in Safe Mode or with the "Enable low resolution video mode (640×480)" option.

I'm using VirtualBox. I installed Linux, worked on it, then turned off the virtual machine. When I tried to start it, after loading there was a black screen with an underscore at the top left. The laptop itself works, the virtual machine does not.

Answer. If you save the state (Suspend) on the virtual machine, in principle, no problems should arise. If you turn off the virtual machine, then Linux tries to boot when you turn it on. Why a black screen with an underline appears after rebooting Linux is a separate question. Check the key settings of the virtual machine. If the error persists, try installing Linux on Vmware Player.

I have this problem. It's Windows 8.1, I installed a third-party theme, I decided to delete it, I deleted the entire themes folder from Windows, although not all the files could be deleted, that's okay, I rebooted the computer and after selecting the OS I got a black screen and, no, no, the cursor appears and disappears and bottom toolbar, tell me how to get rid of the black screen? There is no restore point, no image, and no disk with the OS.

Answer. If possible, find a bootable image of USB Boot or the like on the Internet, write it to a flash drive. Find the Themes folder on the Internet or on a disk and, with administrator rights, copy it to the previous location from which you deleted the files.

Without an installation disk, it is unlikely that you will be able to get rid of the black screen in any other way.

When I turned on the computer, nothing appeared. The light shows that the camera is working and the computer is turned on, but the screen shows zero. What is the problem - RAM or hard drive? How to check?

Answer. To diagnose the problem, it is advisable to recall previous events. Did your computer show any symptoms of failure (hard drive noise), did you delete system files on the drive, etc. This will help narrow down the list of possible causes. Next, watch at what stage the black screen appears. If the hardware initialization is successful, then the problem is in the operating system - that is, Windows does not start. In this case, we recommend reinstalling the OS from a bootable USB flash drive or disk.

Good afternoon Since the evening the computer has been freezing. In the morning I turned it on on the screen - it is necessary to restore the device, error 0x00000e9. I tried to restore via input and the F8 button, as indicated, there were no changes on the screen. I turned off the computer and touched all the wires. I turned on the black screen, turned it on and off several times, still no change, black screen. Now I installed the Windows disk, the system unit beeped, I could hear it starting up, but still the black screen. What should I do next?

It was 8.1, everything was just flying, the system was completely on an ssd, then I had the urge to reinstall win 8.1 on win 10 after the reshuffle, for a couple of days everything was fine, now at startup the black screen and the cursor hangs for 3-4 minutes after Windows is slow and with glitches, but still... it starts

Windows does not load, it constantly reboots when loading Windows, before that it shows a black screen and with inscriptions, I cannot enter safe mode, it enters the BIOS, what should I do?

Black screen on startup. The indicators are all on, I tried just rebooting, it worked the first time, but then the black screen again. I connected it to the TV, everything worked well, what's the problem?

Windows 7 boots fine for me at first. But if you turn off the computer and turn it on again not after 10 minutes, but earlier, a black screen appears without a cursor. At the same time, the monitor light blinks, which, as I noticed, indicates that the screen will be black all the time. But still, after this, Windows 7 loads - as evidenced by the Windows 7 welcome sound, but the screen still remains black and the cursor is not visible. To turn it off, you have to press the button on the system unit. My video card drivers have been updated to the latest version from the manufacturer's website. System Restore doesn't work. Viruses and malware have been removed. How can I remove the black screen?

During the installation of AMD drivers, the brightness suddenly disappeared. Rebooted, the boot selection menu is activated. When turned on normally, the brightness is very low, you can only see anything with a flashlight. The brightness is at standard, but the screen is dark. OS Windows 7. Please tell me what to do.

I have Windows 8 installed at work. Empty. Well, a couple of small files. It takes a long time to open the file. And it generally takes a long time to load. In another office on the computer, I also made a bootable USB flash drive on it. Can I use it to restore my computer? When restoring on mine without a flash drive, it says that “some files are missing. Insert a recovery disk.” since I am only a user. I'm afraid of completely screwing up the system. But it works fine and loads normally, it just takes a long time.

Hello, this situation happened. The Lenovo tablet has stopped working; when I press the power button, the screen does not respond, but the backlight is visible. The screen was broken, but a year had already passed since that incident and everything was working well, and in the last few days the screen simply went out, in parts, but immediately responded to being turned on. What could this be and how can I fix it?

The appearance of a black screen when you turn on a computer with Windows on board is a very common phenomenon. There are many reasons for this behavior of the system, as well as methods for eliminating such problems. But in order to choose the most suitable solution, you first need to understand what exactly such failures may be associated with.

Why does a black screen appear instead of loading the operating system when I turn on my computer?

Before considering the main reasons for this phenomenon, it is worth paying attention to the state of the screen itself. The most common variations are:

black screen with messages when turning on the computer;
blank black screen when turning on the PC or rebooting;
black screen with cursor.

As for the reasons for this phenomenon, in the first case you should pay attention to exactly what messages are displayed on the screen. For example, when it says that it is booting from a non-system drive, this means that the system is accessing an optical drive or flash drive that is currently connected to the computer, but does not have bootloader files on it. Just remove them (from the drive or port) and restart.

If the message indicates that the operating system or, even worse, the hard drive is missing, the problem is much deeper, and to restore the computer’s functionality you will have to use drastic methods, which will be discussed separately.

Finally, one of the reasons could be a damaged or missing graphics adapter driver. If anyone doesn’t know, after the initial check of system components in the BIOS, when transferring control of the computer to the system boot loader, the video card is first activated to display the image on the screen. If there are problems with it, the operating system will not be able to start.

Black screen when turning on the computer: what to do first?

But it is not all that bad. It may well be that the reason is not software failures or damage to the computer hardware. As it sounds, after turning on the computer, a black screen may appear only because the brightness on the monitor is reduced or it is in standby mode (the LED is blinking). Another situation may be related to damage to the power cable or connection to the video card. It needs to be checked, and at the same time see if the contacts are oxidized. However, physical breakdowns and minor malfunctions are usually not cited as the main reasons, so let’s move on to troubleshooting problems at the software level.

Quick system recovery

Let's start with a situation where, when you turn on the computer, the black screen on the monitor does not “hang” constantly, but disappears after a certain period of time. In this case, the operating system can start loading as usual. If the start is impossible, you need to reboot again and use access to the start boot menu, which is called up by pressing the F8 key (for systems higher than the seventh version, the combination of F8 with the Shift key sometimes works, but it is better to first use the command line and return to the normal boot method by setting to execution of the command bcdedit /set (current) bootmenupolicy legacy followed by rebooting the system).

If, when you turn on the computer, the black screen gives way to calling the boot menu without problems, you can use the standard boot option to the last known good configuration, which is analogous to the most common system restore from an OS checkpoint with working parameters.

Standard system rollback

If for some reason the user is not satisfied with the previous method, for example, because he needs to restore the system from another point, but a standard boot turns out to be impossible, in such a situation using start in safe mode is suitable.

After the download is complete, you should enter the system recovery section through the “Control Panel” and perform the standard rollback procedure by selecting the appropriate point from the list, having previously displayed all temporary components.

Actions when booting from removable media

If none of the rollback options work, and when you turn on the computer the black screen appears again, you can use some system tools available when booting from an installation or recovery disk (flash drive), which must be set as the first priority in the settings of the primary BIOS input/output system downloads.

Note: if UEFI is used as the primary system, the flash drive must first be formatted in FAT32, since the NTFS file system is not accepted for UEFI booting.

After starting, it is advisable to immediately go to the command console (Shift + F10) and check the system components by entering the command sfc /scannow.

The process may take quite a long time, so you will have to be patient. Just in case, you can also use disk check, supplementing the main chkdsk command with accompanying attributes, which can be found by calling the help information (chkdsk /?).

Note: if running the above commands does not produce any results, and the black screen appears again when you turn on the computer, you can boot from the removable media again and run the online recovery commands DISM.exe /Online /Cleanup-image /Scanhealth and DISM.exe / in the console Online /Cleanup-image /Restorehealth.

Problems with the video card driver

The methods described above are universal and help restore system functionality in 99 percent of cases out of a hundred, but only if this is due specifically to software failures of the OS itself. But most often the problem lies in the graphics accelerator driver, since a black screen when turning on a computer with Windows 7 or any other system can appear for this very reason.

To reinstall or update it, you will need to at least start in safe mode, after which you will need to call the standard “Task Manager” (devmgmt.msc) and try to update the driver using the operating system.

If this doesn't help (most likely it won't), it makes sense to use utilities like DriverPack Solution Online 17 or Driver Booster, which can update the control software without user intervention. The only condition for a correct update is an uninterrupted Internet connection (when selecting the download mode in the initial menu, you should use safe mode with loading network drivers).

Problems with updates

Finally, a black screen when you turn on your computer may also appear when installing critical system updates. This most often manifests itself in Windows 7, for which the updates themselves are full of bugs, and for computers with Windows 10 that have AMD processors installed (the recent failure of AMD-based systems after the “dozens” update around the world is a clear confirmation of this). To fix problems, in safe mode you need to use either the “Update Center” or the Programs and Features section, then remove the faulty packages one by one, checking the system’s functionality, then set up a manual search and exclude the faulty components from the list of required installations).

Note: to simplify the removal of update packages, it is recommended to use programs like iObit Uninstaller, in which such procedures are carried out in the most complete manner.

Restarting the Explorer Service

Another reason why a black screen appears when you turn on your computer is a malfunction of the Explorer service (not to be confused with Explorer). To start, in safe mode, you should call the “Task Manager” and force quit. After this, you need to create a new task through the file menu, enter the name of the service you are looking for in the line and confirm the execution of the command by clicking the “OK” button.

Nuances of power supply settings

Sometimes this system behavior may be due to incorrect settings of the current power supply scheme. This concerns the so-called quick launch parameters.

Activation of this mode can be done through the button action sections and changing parameters that are currently unavailable. After installing the necessary options, you should reboot and see how the system reacts to the measures taken.

Disabling Windows Permanent Reactivation

Finally, one of the reasons, many experts cite problems associated with the file responsible for activating the system, when its operation can go in cycles. To correct the situation in the system root folder for 64-bit OSes or in the System32 directory for 32-bit systems, you need to find the Windows Activation Technologies directory, then in it successively go to the Tasks and Microsoft subfolders, then in the last directory delete the Windows directory with all its contents and restart the system.

Note: in order to avoid deleting the folder, you can simply stop the service of the same name in the appropriate section and set its startup type to disabled and disable it in automatically booted processes.

Brief summary

That, in fact, is all about the appearance of a black screen instead of the expected loading of the operating system. As you can see, the methods for correcting such a failure are not particularly complex. In most cases, unless the main problem is related to failures in the operating system itself due to damage to its components, it is enough to check the graphics adapter driver and, if necessary, update or reinstall it. In all other cases, you can restore normal operation of Windows either through safe mode or by booting from removable media, which seems more preferable, since the tools present on it do not directly depend on the behavior of the OS installed on the computer’s hard drive.

However, if we are talking about a hard drive, for example, in situations when it begins to “crumble”, in order not to change it immediately and to be able to transfer important information to other media, you can use a unique and one-of-a-kind recovery program called HDD Regenerator , which is said to be able to remagnetize the surface of the disk, which allows you to avoid data loss or recover it.

Today we will talk about how to remove the black screen when you boot your computer and what it actually is.

Let me describe all the reasons that can cause a black screen when booting a computer, and below I’ll tell you in more detail about them one by one, and also explain how to properly deal with a black screen.

Driver problem. (most likely with video adapter drivers)
The monitor or cable (VGA, HDMI, etc.) does not work. This also includes user errors. (The monitor is not plugged in, the cable from the video adapter does not go to the monitor. If you have 2 video drives, then maybe you inserted the cable into the wrong slot)
The operating system has already outlived its usefulness. Reinstallation required. In this case, usually when the computer boots, the black screen will not be blank, but with some kind of error.
PC needs to be cleaned from dust
Serious hardware problems.

I would also like to divide all the black screens when loading into 2 categories, and I think you will agree with me.

The problem is with the PC hardware.
The problem is in the PC software.

Finding out which category your problem falls into is very simple: If, when the computer boots, a black screen appears immediately (that is, no characters appear on the monitor before Windows starts) – you have a hardware problem, and if the PC writes something (and even the system may start to boot) and then goes out, then most likely you have a software problem.(that is, the problem is in the drivers or system) The only exception is the hard drive.

When problems occur with the hard drive, the system does not boot (or takes a very long time to do so) and the computer usually displays an error, for example in the following format:

The Internet is full of instructions on how to check your hard drive. I recommend the program Victoria 4.47. She also knows how to repair damaged sectors.(unless of course they are damaged by software)

Also, if when you boot your computer there is a black screen with some kind of error written on it, go ahead and type this error into the search bar. You are not alone in this world with a similar problem. I guarantee you that what happened to you today happened to others much earlier. They described their problem and were helped to find a solution. Good luck in your search! =)

So, I really delayed the introduction... let's get down to business, namely Let's go through the list of reasons why a black screen appears when you boot your computer.

1.Problem with drivers.

Most often, a black screen appears when loading a PC precisely because of this. And 90% of cases are due to the video adapter driver. Let's say you bought a new video card (or reinstalled the system, or decided to simply update the old driver) and after installation the system rebooted, but was unable to fully boot, and instead got a black screen. (sometimes with a cursor) There are many reasons why this happens: the PC simply does not support the new video card, crooked drivers, a very old system (not suitable for new firewood and as a result) too (so to speak) “sophisticated” firewood for and so on.

Well, we seem to have sorted out the driver problem. Let's now move on to the solution.
And the solution is very simple. You need to press the F8 key when you turn on the computer. The following menu will appear:

Here you need to select “Safe Mode” and after it loads, right-click on the “Computer” icon and select “Manage”. Next, go to “Device Manager”, select the video adapters tab there, click on it and remove the driver you installed. To remove a driver, right-click on it and select remove. That's all. After this, the system should boot “as usual”. You also now need to read more about how to do this correctly in the section If the system still cannot boot normally, then again we go into safe mode. Click the “Start” menu, select “All Programs” then “Accessories” then “System Tools” and click “System Restore” Read more about how to perform a system restore.

2.Monitor or cable does not work

When booting the computer, the black screen may be due to the fact that the monitor is simply not plugged in or the power cables and picture transmission cables are slightly loose. Try tucking in all the cables. Also, a black screen during boot may appear due to the fact that the cable is inserted into the wrong video card.. (There are computers that have a video card built into the motherboard and plus it has a connector for another video card (more powerful). In this case, the cable should be inserted into the video card that is inserted into the motherboard slot) Here is an example :

It happens that the picture transmission cable or, even worse, the monitor stops working. It's very easy to check. It is enough to connect the computer to the TV with the same cable. If everything on the TV shows without problems, the monitor is faulty, and if it doesn’t show, then either the cable or the computer is faulty. Read the article further and you will be able to diagnose and solve the problem yourself, because here I describe absolutely all the reasons why a black screen appears when you boot your computer.

3.Reinstall Windows.

Do you get a black screen when you turn on your PC? Everything is simple here. If the system before the “black screen” was giving out and generally living its own life, and now when you boot the computer a black screen with errors appears, then it makes sense to check the hard drive, and if everything is fine with it, then reinstall the system.

4. The computer needs to be cleaned from dust

This is another reason why a black screen may appear when loading your PC.

Any computer sooner or later needs, and the fact is that dust is a very good conductor and can greatly interfere with the operation of the PC. Also, due to overheating, the computer may turn off. In my practice, most often it was necessary to clean the computer from dust. (you need to remove all components from their slots and blow them out.) The very first thing in case of heavy dustiness is that the RAM stops working., and the first thing I always did was take out the RAM dies, blow out their slots, clean the dies themselves and insert them back. After that, the computer turned on as usual, but I still cleaned it completely (since I got around to it.)

5. Serious hardware problems.

If you have tried all of the above and still get a black screen when you boot your computer, then most likely you are faced with a serious problem. Most often the video card burns out.

The precursor to this is various streaks on the screen and artifacts.

The video card burns out due to the fact that the computer has not been cleaned for a long time and most likely the video card fan is clogged and can no longer cool it properly.

If you have 2 video cards (built into the motherboard and another that is inserted into the slot), then you have the opportunity to check the video card’s functionality. To do this, remove the video card from its slot and connect the “picture” transmission cable to the video card that is built into the motherboard. Turn on your computer. If everything works, go to the store for a new video card. If you have one video card, go to a friend and remove the video card from his computer. Insert it into the slot, connect the cable to it and turn on the computer. If the computer comes to life, go to the store for a new video card.

I will not describe more complex hardware problems (replacing the processor, motherboard), since this is too complicated for the average user, and advanced users solve such problems on their own.

If after reading this article and using ALL the methods described here, the problem is not solved - I recommend contacting a service center to diagnose and fix the problem. Wish you luck!
