Why does Windows 7 boot through f1. F1 when turning on the computer
RAM in a computer plays the role of a temporary buffer for storing information, that is, when you start an application, it is partially loaded into RAM, therefore, the more memory you have, the more you can simultaneously open and work in several programs, for example, play playing a computer game and listening to music at the same time.
A large amount of RAM is required in modern games, since they began to have large game spaces and in order to load them, those same megabytes of RAM are required.
RAM has two main characteristics: its quantity and the frequency at which it operates.
The amount of RAM is measured in megabytes; memory sticks can have sizes of 32,64,128,512,256,1024,2048 megabytes, etc. These values do not directly affect the amount of possible storage of information in it.
The frequency of RAM affects its operating speed, for example, if with a frequency of 600 megahertz the RAM will load 100 megabytes in 10 seconds, then with a frequency of 1000 megahertz it will perform the same operation in 5 seconds (the numbers are conditional, just to make it clear to you what is frequency used for?
Let's look at 3 types of memory DDR1, DDR2, DDR 3
There are different types of RAM, they differ in the possible frequency and in the input to the motherboard. We will not take old varieties, we will consider only DDR1, DDR2, DDR3
DDR1 is already an outdated memory standard, possible operating frequency up to 400 megahertz.
DDR2 is the most common memory standard today, operating frequency up to 800 megahertz.
DDR3 is a new memory standard, operating frequency up to 1800 megahertz.
It is also worth considering that each type of memory requires its own motherboard, that is, if the motherboard has slots for DDR1, then no other memory will work on it.
However, you won’t even be able to install other memory into the slot, since they all have different sizes and each type of memory has a special cut (key) on the connector; it must coincide with the cut on the memory slot on the motherboard.
The key is also made so as not to make a mistake and not put the memory in the slot on the wrong side.
Although there were cases when people almost hammered an inappropriate memory into a slot, and even the key (I call it foolproof) did not stop them. As a result, smoke, short circuit, burnt RAM and motherboard.
Specifics of frequency substitution
Two more points should be taken into account, namely, if the motherboard supports DDR2 memory and the bus of the motherboard memory is 533 megahertz (you can find this out in the documentation for the motherboard), then if you install DDR2 memory in it with a frequency of 800 megahertz, then it will work equal at the bus frequency, that is, at 533 megahertz.
The second point is that if you install two memory sticks and each has different operating frequencies, then both of them will operate at the frequency of the memory stick with a lower operating frequency. For example, you installed two memory sticks, one with a frequency of 800 megahertz and the other with a frequency of 600 megahertz, in which case they will both operate at a frequency of 600 megahertz.
Sooner or later, on almost any computer, when you turn it on, you need to press the F1 or F2 key. If this is not done, it simply will not turn on, remaining hanging on a black background with white letters. In this article we will tell you what this means, as well as how to get rid of constantly pressing the F1 button when turning on the computer.
Why does the computer ask you to press F1?
There are several possible reasons why you need to press the F1 button every time you turn it on. Thus, the system draws the user's attention to the presence of a problem. There is always a message just above the line “Press F1 to continue”, which caused the request to press F1 to appear. Now we will look at all possible options.
CMOS checksum bad/CMOS Checksum Error
Error loading Cmos checksum bad
Smart status bad backup and replace/Immediately backup your data and replace your hard disk drive
If there is a similar phrase before the phrase “Press F1 to continue,” this means that the hard drive is in poor condition. As, it is recommended to immediately copy important data to another hard drive and replace the current one.
Smart status bad backup and replace
CPU fan error
cpu over temperature error
Chassis intruded!
If the case tamper detection option is activated in the BIOS, then in this case the message “Chassis intruded!” will be displayed. You just need to go into the BIOS settings and disable it.
Chassis intruded! Fatal Error…System Halted
Intel cpu ucode loading error
This message indicates compatibility problems between the processor and motherboard. Most likely the motherboard BIOS needs to be updated. More details about the error in .
Many people are interested in the question of why the computer does not boot and constantly has to press f1 when loading? Many users are faced with this minor, but a couple of very annoying malfunctions. After turning on the computer, after a couple of seconds the screen freezes, and on a black background at the bottom left it says Press f1 to continue and it won't load any further.
To continue loading, the user has to press the f1 key, but this does not always help. Of course, there are many reasons why a computer won’t boot, but the main ones are a dead BIOS battery, an unconnected keyboard, a floppy drive not turned off in the BIOS, and a faulty cooler on the processor or video card.
As a rule, next to the inscription is written the reason why the computer refuses to boot on its own. Next, we will describe the main messages on the monitor screen that appear before the operating system boots. To eliminate some messages you will have to go into the BIOS. If you have never done this, we recommend reading the article on how to enter the BIOS.
Reasons why the computer does not boot without pressing F1
CMOS Battery Low – the BIOS battery is faulty. Because of this, the time in the operating system is constantly reset. Most likely you will see the date January 2002. It also happens that when you start your browser, the message on the monitor says the server certificate has expired. All these malfunctions indicate a 100% dead battery. This problem can be fixed quite easily. We go to the nearest store or kiosk that sells batteries, buy CR2032 and replace them.
We open the system unit, find the battery, carefully remove the old one, and install a new one in its place. After loading, press DEL, a blue screen appears, go to the Standard CMOS Features (SETUP) or MAIN menu and set the time and date. Don’t forget to save the settings when exiting; exit BIOS via Save & Exit Setup. After all the manipulations, all faults should disappear.
Floppy disk(s) fail (40) appears due to the Floppy drive. Many users, mostly in older computers, have a floppy drive installed. This is also very easy to fix: open the system unit and remove the cable from the floppick, and at the same time turn off the power.
Well, for those who are too lazy to get into the system unit, immediately go to the BIOS in the Standard CMOS Features (SETUP) or MAIN tab, select the Floppy Drive A 1.44MB menu and set it to Disabled mode. We also exit via Save & Exit Setup. The next time you boot, the computer should boot without pressing the f1 key.
CPU Fan Error! Another reason is a faulty or insufficiently rotating cooler on the processor or video card. Replacing the cooler or eliminating the reasons why it rotates more slowly will eliminate this inscription, after which the computer will begin to boot in normal mode.
We hope that after reading this article you have found the answer to your question and you will never have to press f1 when loading.
A fully functional operating system loads 100% on its own, without requiring any user intervention. However, if certain problems occur, already at the very beginning of the PC startup, a message appears on a black background requiring you to press the F1 key to continue. If such a notification appears every time or does not allow the computer to start at all, you should figure out what caused this phenomenon and how to fix the problem.
The requirement to press F1 when starting the system is due to different situations. In this article, we will look at the most common ones and tell you how to fix them by disabling the keystroke prompt.
It’s worth noting right away that the operating system in this case has nothing to do with the problem under consideration, since it is formed immediately after switching on, before the OS starts.
Reason 1: BIOS settings failed
BIOS settings quite often get lost after the computer is abruptly disconnected from power or after the PC is completely de-energized for a certain period of time. Despite the fact that in general the situations are similar, their appearance is provoked by different factors.
Login to BIOS
Resetting BIOS settings
An unexpected power outage or some internal failure at the BIOS level may cause the requirement to appear "Press F1 to Resume", "Press F1 to Run SETUP" or similar. It will appear every time you turn on the computer until the user resets the BIOS settings. This is easy to do even for a novice user. Check out our article about different methods for solving this problem.
Making the HDD bootable manually
When connecting multiple hard drives, there is a chance that the PC will not be able to understand which device it needs to boot from. Fixing this couldn't be easier, and we have a separate article on our website that will help you set the desired hard drive to the highest boot priority.
Disable Floppy in BIOS
On older computers, an error like A: Driver Error most often appears for the same reason - the equipment searches for a Floppy drive, which may not be present as such in the system unit. Therefore, through the BIOS you need to disable all settings that in one way or another may be related to the floppy drive.
By the way, sometimes the previous tip can help - changing the download priority. If the floppy drive is installed first in the BIOS, the PC will try to boot from it and notify you with a message if the attempt fails. By putting the hard drive or SSD with the operating system in first place, you will get rid of the requirement to press F1. If this does not help, you will still have to edit the BIOS.
Reason 2: Hardware problems
Now let's move on to a description of problems in the operation of PC hardware components. You can recognize which component has a problem by looking at the lines preceding the inscription “Press F1...”.
CMOS Checksum Error/CMOS Checksum Bad
This message means that the battery on the motherboard that stores the BIOS, time and date settings has run out. This is confirmed by the time, day, month and year constantly being lost to the factory default and notification "CMOS Date/Time Not Set" Near "Press F1...". To remove the intrusive message, you will need to replace it. This process is described by our author in a separate manual.
Many users receive the same message even though the battery itself is fine. This inscription may be preceded by "Floppy disk(s) fail (40)". This type of error can be resolved by disabling Floppy-related settings in the BIOS. Read how to do this above, in the subtitle “Disable Floppy in the BIOS” of Method 1.
CPU Fan Error
CPU Fan - cooler that cools the processor. If the computer does not see this device when turned on, you should check its functionality.
Keyboard Error/No Keyboard Present/No Keyboard Detected
From the name it is clear that the computer does not see the keyboard, ironically suggesting that you press F1 to continue. Check its connection, the cleanliness of the contacts on the motherboard, or purchase a new keyboard.
For many of us, the computer is an integral part of our lives. During long-term use of the same computer, turning it on and off becomes such a monotonous task that we perceive the appearance of an inscription in the form of a request to press F1 or Del during boot and enter the BIOS for settings as a serious breakdown. Then, having looked in the settings, we see that either the settings have gone to default, if we understand them, or nothing has happened. But why then does the inscription appear? - We suggest you look into this note.
As a rule, the appearance of this inscription is described by people who brought a computer to a computer service in Moscow after it stopped loading altogether, so the appearance of the above inscription should be considered a symptom of future problems. The first and most common reason for the request to go into the BIOS settings was once the battery of the CMOS read-only memory, where the computer settings are stored, was low. But modern CMOS memory has begun to consume so little memory that motherboards with one battery can easily operate for ten years or more. Therefore, the most common reason for resetting BIOS settings is an error in the device test when booting the computer.
Most often the error occurs on the part of hard drives and solid state drives. The latter began to be sold recently, so these are often hard drives. Hard drives die and S.M.A.R.T error data is entered into their controller. The presence of these problems can be easily determined using the CrystalDiskInfo program. The program is free and will notify you if there are problems with your hard drive. If there are problems, you need to buy a new data storage device that same day and transfer everything valuable there. Then you can remove the hard drive from the system and the message will no longer appear.
The third most common cause of problems is the instability of your power supply. Voltage surges of 5 volts, 12 volts, 3.3 volts are monitored by the motherboard and are indicated in the settings in the “monitoring” tab. If this is really due to voltage sags, you need to change the power supply, since it allows sags without any serious loads. This problem also occurs when the processor fan suddenly stops or does not start. As a rule, this occurs due to its burnout or some cord getting caught in its blades.
