The average user usually cannot say exactly what processor system interrupts are, since they are considered to be something from the realm of science fiction. But when a process of the same name appears in the “Task Manager”, loading system resources, it’s time to think about how to fix the problem. But first, a little about what it is. An explanation of all these processes and methods for correcting the situation as much as possible is offered. accessible language for an unprepared user.

What are system interrupts?

They can be interpreted not as a specific system process, but as a kind of indicator in the form of a kind of litmus test, which only indicates that some “hardware” device is not working correctly or does not work at all.

In other words, system interrupts in the same “Task Manager” are the process of checking computer components. Typically, the processor load for this process (in normal computer condition) does not exceed five percent. If the load increases, this can be considered the first bell indicating that some device has failed (the hard drive has fallen down, the brackets are not working random access memory etc.). Sometimes systemic Windows interrupts 10 or versions of the system of earlier generations are associated with obsolescence, incorrect installation or lack of device drivers. But in most cases this refers to an increase in the load on resources indirectly.

Why do Windows 10 system interrupts load the processor?

Now a few words about the reasons for the increase in load. Speaking in simple language, it can be noted that in Windows 10, system interrupts load the processor only for the reason that when functional failures in the performance of some component are detected, the processor takes upon itself the execution of commands addressed to the failed devices, since they simply ignore or skip them.

Accordingly, if the device does not work, the CPU and RAM, as they say, carry it all on their own back. However, it is possible to get rid of such a scourge. And it is not always advisable to replace equipment, although in most cases this is the root cause of increased loads.

Initial steps to check the equipment

In order to find out exactly what exactly is causing the failures, it is recommended to use non-system Windows tools, but third-party utilities.

However, you can use this tool first. In this situation, you need to enter the "Device Manager" (devmgmt.msc in the "Run" console) and disable all devices in the list except the computer, processor and system components, and then look at the CPU utilization level (disabling these three components should not be done under any circumstances, as this can lead to a crash and problems when rebooting the system). Next, you just need to turn on the devices one at a time, finding out which of them affects the load level.

Interrupt Checker

It's much easier to track system interrupts if you use a small portable utility called DPC Latency Checker (it doesn't require installation).

To get started, simply set the scan to start. The results will be shown in the field located at the bottom of the main window. There are troubleshooting tips here too, but they direct you to the same “Device Manager” for diagnostics there. But only if this is related to the processor itself or system devices, for quick solution problems, you can simply try to reinstall or update the drivers for the relevant components.

You can use programs like Driver Booster, which search for and install updates in automatic mode(the user is only required to activate scanning and agree to install updates).

What else could it be?

Sometimes the interrupt load is also associated with some additional settings systems. In particular, it is believed that the use sound effects For older or integrated sound cards, this may cause excessive load. Indeed, this can also happen.

Therefore, in the setting Windows sound On the enhancements tab, disable the use of all effects.

Finally, some experts attribute the increase in interrupt load to outdated firmware of the primary BIOS/UEFI input/output systems. The solution is to update the firmware. With UEFI this is quite easy to do, since the update file can be run directly in the operating system environment, after which the update will be installed upon reboot. In BIOS this procedure looks a little more complicated. If there are update settings there, you can use them, but on most systems you will have to download them initially required file, and only then launch the update, and specifically from the primary, and not the operating system. The procedure, I must say, is quite troublesome, and without special skills it is better not to do such things, otherwise the whole computer system can simply be rendered completely unusable.

Conclusion

Finally, it remains to be noted that in the event of a malfunction of the RAM, you can use the Memtest86+ program for diagnostics or check the failed strips by removing them from the slots on the motherboard. As soon as the faulty strip is detected and the system boots normally, the load on the processor in the form of interruptions will instantly and significantly decrease.

In general, every user should clearly understand that if such a situation arises, the problem is most likely in the hardware, and not in the drivers. Although... you never know what can happen. And these were only the main causes of failures and diagnostic methods. It is likely that custom manual computer configurations will require downloading and using diagnostic programs for each individual device. But it is recommended to download such applications exclusively from the websites of equipment manufacturers or the corresponding developers in the form of support services. In the case of laptops, you can use standard means online diagnostics, which are available on any Internet resource of a self-respecting manufacturer.

Common operating system problem Windows any edition is the loading of computer resources by “internal” processes. One such process is a system interrupt, which can seriously load the computer's resources, which will be displayed in the Task Manager. The most common situation is when a system interrupt loads the processor, causing the computer to seriously lose performance. In this article, we will look at why this happens and whether it is possible to disable system interrupts in Windows.

System interrupts: what is this process

The System Interrupts process is always running by default in the Windows operating system, but when regular work it should not load the system components by more than 5%. If this process has a more serious impact on computer resources, this indicates the presence of a hardware problem, namely a malfunction of one of the computer components.

When “System Interrupts” load the processor, this may indicate a problem with the video card, motherboard, RAM or other element system unit. The central processor tries to supplement the missing power resulting from the malfunction of the component using its own resources, as evidenced by the “System Interrupts” process. Most often, the problem of computer components not working correctly is associated with complete or partial incompatibility running program(or games) with computer component drivers.

How to disable system interrupts

As noted above, system interrupts are nothing more than an indicator that the Windows is coming additional access to CPU resources. It is not possible to disable system interrupts to improve computer performance, and you need to look for a problem in the operation of PC components. To do this, it is convenient to use the DPC Latency Checker application, which can be downloaded for free on the Internet from the developers’ website. The program allows you to identify faulty computer components.

To diagnose your system with the DPC Latency Checker application, launch it and wait. It will take some time to check the computer, after which the user will see on the graph if there are problems in the operation of system components. The application will also indicate possible mistakes and advise you to look for them by turning off the devices.

To do this, go to "Device Manager" by clicking right click mouse to “Start” and selecting the appropriate item, and start disconnecting devices one by one. After each shutdown, check in the Task Manager and the DPC Latency Checker application to see if the problems with CPU load due to system interrupts have been resolved. If the problem persists, turn the device back on and move on to the next one.

Important: While disabling components in Device Manager, do not disable Computer, Processor, and System devices"otherwise it will lead to emergency reboot computer.

When a device is found that, when disconnected, will reduce the CPU load to normal condition, update the drivers for this component from the official developer website.

Note: If attempts have been made to disable all system components, but the System Interrupts process continues to load the system, try updating the processor drivers.

In a situation where the tips given above do not help to cope with the problem of processor loading by system interrupts, you can try the following methods to correct the situation:

It is worth noting that you should not disable system interrupts through the Task Manager; this will cause the system to crash, but will not solve the problem.

Welcome! This blog is dedicated to the Internet and computers, or rather was dedicated to them.

It’s probably immediately obvious that no new articles have appeared on the site for many years. Yes, this is the fate of most blogs. This project was once an ambitious undertaking, and the author, like many others writing at that time, had ambitious plans to become one of the best Russian bloggers. Well, if you look now, of those blogs that were created simultaneously with mine, most have already disappeared into eternity. And I just simply didn’t have enough time to blog. So yeah, it's not updated anymore. Although we once won the “Runet Blog 2011” competition with this site.

I even had the idea of ​​deleting all this, but then I reviewed the old materials and realized that they could still be useful to readers. Yes, some articles are outdated (if I have enough strength, they will be marked accordingly), but the site, for example, can be useful for beginners - here you can read about basic concepts Internet, learn how to set up the Internet, Windows, or even decide to switch to Linux. So take a look at the categories and choose the one that suits you.

And yet, I hope that this is more than just a blog, but a real guide to the Internet. The site can be viewed in directory mode, where all available articles are structured by categories. And, who knows, maybe one day new high-quality articles will start appearing here.

Modern Android phones are more than just phones. You get used to the set of installed programs, the history of your calls and text messages, photo collections and much more. But time is running, and the device that suits you completely begins to slow down, glitch, or simply loses presentable appearance due to chips on the case or scratches on the screen. The question arises of choosing a new phone and changing android phone. And if we now bypass the question of choice, then “moving” to new phone remains a serious problem - I absolutely don’t want to start all the data from scratch. This is what we will talk about today.

Most of the readers of this blog have most likely never encountered version control systems and will not encounter them in the near future. It's a pity. This extremely convenient invention is quite widely used by programmers, but, in my opinion, it could also be very useful for those who actively work with texts. But, probably, now there is not a single version control system that would be easy to start using for “office” ( Microsoft Office) work. Nevertheless, I think that the material presented in the article may be of interest to all readers.

If you have been wondering how to watch movies online and access the Internet from your TV, this article is for you. No, I know that some TVs already have Smart TV functionality, but I have never seen it work properly. Apparently, this is why Google recently demonstrated an absolutely stunning device that immediately became a sensation. It's about about the Chromecast media streamer, a more advanced and available version last year's disastrous Nexus Q player.

Chromecast dongle, the size of which does not exceed 2 inches, is connected to the port HDMI TV and allows you to enjoy watching streaming web content. To control the streamer, you can use any device (tablet, PC, smartphone) based on operating platform iOS, Windows, Android or Mac OS.

This article is about the device system memory android, problems that may arise due to its lack and ways to solve them. Not long ago I myself was faced with the fact that my phone is on android base began to regularly display messages about low memory when trying to install this or that application. Which was very strange for me, given that according to the description on the market there should have been about 16GB, and I also increased this volume using an additional memory card. However, there was a problem, and I had to tinker a lot before I found the right solution that did not require root access or full recovery phone to factory condition.

In many cases, users are faced with a sharp decrease in the performance and speed of their computer. System interrupts are often to blame. We will talk about what this indicator is, what it depends on, and methods for adjusting it in our article.

Why does the processor overload during system interrupts?

As a rule, this problem occurs in cases where equipment or drivers for peripherals are installed incorrectly. We will tell you how to optimize system interrupts and get rid of the problem slow work.
In order for interrupts to completely block the work of the central processor, the SP must occupy more than 30% of the total number of processes. Interruptions less than this indicator do not affect performance in any way, but more interruptions lead to freezing.

The concept of "system interrupts" and troubleshooting computer problems

Let's discuss the question of what are system interrupts shown in the task manager. Although not a system process, SPs can be shown in the Task Manager window. They inform you about the processor load level.

Interrupts can be classified as follows:

• Having the highest priority (non-maskable). They arise when errors appear in the operation of RAM or another device.
• Hardware (masked). Triggered by peripheral devices.
• Software. Carried out due to the fault of the software

For SP processing CPU is not involved, but implementation occurs in other ways.
Most common cause periodic decrease in computer performance, experts consider installed incompatible devices on the computer, and also incorrectly installed programs, outdated and not original drivers and even problems with the functioning of the processor itself.

The processes discussed occur when, while a series of sequential tasks are being performed by the processor, the user gives a command to perform a new task. For example, while waiting for a response from a running program, he clicks the mouse on the shortcut of another program or command. New task is placed in the execution queue, but the processor gives it priority in execution. After its completion, the sequence of task execution is restored. But it is precisely at the moment of execution of an extraordinary task that the performance decreases.
That is, by definition, SP is a standard workflow of the Windows 7 and Windows 10 operating systems, which notifies about the presence of problems in the operation of a device or in the execution of a program. Interrupts are related to indicators in their function.

System interrupts - how to fix them

In such cases, no action on the part of the user is required to enable the interrupt, since this system task is included in the registry of the Windows operating system and begins its action automatically. Such a process in a software environment is called virtual interrupts. But this one system function, but in relation to installed drivers equipment also reduces system performance. But it is already software. It is controlled by the system interrupt controller and its driver directly.

Users personal computers The question is often asked about how to remove interrupts from the SysTick system timer. This cannot be done, since SysTick refers to a microcontroller timer; its operating code is written in the system Windows registry, and it is impossible to stop him. You can only change the trigger frequency.

In the screenshot you can see a description of the registers of the module under discussion.

It becomes clear that without possession professional knowledge It is better not to proceed with this issue in order to avoid serious damage to the computer.

How to solve the problem of slow computer performance

But what to do if system interrupts load Windows processor 7? How to streamline processes and eliminate incorrect system tasks? What to do if system interrupts are loading the Windows 10 processor and how to disable them? Let's consider the issue of access to management system processes in operating rooms Windows systems 7 and 10.
We have already written that all interruptions are displayed in the Task Manager. To open it, you need to press the ALT+CTRL+DELETE keys simultaneously. By going to the Processes tab, you can see everything running processes. Having found the problem with the highest processor load in the list, you need to highlight this line and then click the “End process” button. In this way, you can identify incorrect system interrupts and ways to get rid of them.
Task Manager helps solve a sufficient number of problems with your computer, even on your own.


The simplest way to solve the problem discussed is to restart the computer. This can also be done using the Task Manager or by clicking Reset button on the front panel of the computer system unit. On a laptop, this requires a short press Power buttons.

Troubleshoot performance issues using software applications

Let's look at some application programs and ways to solve problems with performance and freezing. An example could be the problem of sound distortion while simultaneously listening to audio files and working at the computer. This can be caused by either RAM overload, incorrect driver audio device or processor overload. The Latency Mon program is used to help the computer user. You can download it below:

This utility helps analyze already running processes and monitor drivers installed on the system.


To detect device problems, you need to start by diagnosing driver problems. And for this there is another program - DPC Latency Checker.

After starting this program you need to run the following actions:

• Close all open source software, having previously saved the results of the work in them.
• Launch the program in question. By the way, there is no installation process required for it. A diagram will open in the window. And already on it you can see with which driver the problem occurred.

All low-level processes are processed in BIOS, that is, in a set of microprograms that implement work with the computer hardware and connected modules. This software environment is used to work with I/O hardware included in the standard hardware interface.

In order to configure the processor in this way, you need to know the table of internal and hardware problems and a number of other parameters that are reflected in Bios.


As we see, the problem under discussion is operating systems Windows is quite common. But with a skillful and intelligent approach to solving it, you can try to bring your computer to the proper level of performance.

Have a great day!

IRQ Priority Management

Managing hardware interrupt requests

Most components directly attached to the motherboard, including PCI slots, IDE controllers, serial ports, keyboard port even CMOS motherboard, separate IRQs are assigned. A hardware interrupt request, or IRQ, interrupts the processor's normal operation, allowing the device to function. Windows 7 allows you to prioritize one or more IRQs (which are translated to one or more devices), potentially improving the performance of those devices.

Steps to change IRQ priority

1. Start by running the System Information Utility (msinfo32.exe) and go to System Information Hardware Resources Interrupts (IRQs) to see which IRQs are used for which devices.
2. Then open Registry Editor (see Chapter 3) and navigate to HKEY_LOCAL_ MACHINE\SYSTEM\CurrentControlSet\Control\PriorityControl.
3. Create a new DWORD value in this section and name the parameter IRQ#Priority, where # is the number of the IRQ device for which you want to set the priority (for example, IRQ13Priority corresponds to IRQ 13, which is the arithmetic coprocessor).
4. Double-click the new value and enter a priority number. Enter 1 for the highest priority, 2 for the second, etc. Make sure you don't enter the same number for two entries, and don't try to do everything at once, but experiment with one or two values.
5. When finished, close Registry Editor and restart your computer.
