Why is the CPU overloaded on the computer. Why is the CPU busy and how to reduce CPU usage? Elementary weak percentage that does not pull ツ

Most often in our practice, the main cause of the processor load up to 100% is overheating. Many users do not know that dust clogging the radiators of cooling systems can significantly reduce the performance of devices. When the processor overheats, it goes into throttling mode, starts skipping cycles and performance decreases.

To check the processor for overheating and look at the temperature of the processor without load and under load. We compare these temperatures with the maximum allowed declared by the processor manufacturer. The maximum allowable temperature can be found on the website of the processor manufacturer in the specification.

Viral activity

When there are a lot of viruses on the computer, this also reduces the performance of the system. Viruses, like regular programs, consume processor resources, this can lead to a 100% load on the percent. I talk a lot about removing viruses on my youtube channel, and be sure to read and follow . After completely cleaning your computer from viruses, there will be no problem with CPU load!

Driver Issues

Another reason for CPU usage is system interrupts, in other words, a problem with the drivers. I recommend doing the following: boot the computer into safe mode and see if there is an increased load on the processor. If there is no load, there is a very high probability that the reason is in the drivers, because the drivers are not loaded in safe mode! The easiest solution to this problem is to uninstall all drivers and then install one driver at a time and see if CPU usage appears as soon as it starts loading - you have found the culprit.

Most often the fault here network cards+ universal drivers from Microsoft, which are installed immediately when Windows installation. I recommend downloading and updating all drivers from the official website of your hardware manufacturer. I showed you how to do it.


Elementary weak percentage that does not pull ツ

For some reason, many people think that their ancient processor should still pull everything normally and without brakes. But this is not so, now digital technologies are developing very quickly and sometimes budget processors of only two or three years ago no longer pull anything today. Even if you have a top processor 10 years ago, this does not mean that it can cope with modern tasks. Maybe heavy load your processor is exactly this, think about it. if you are not sure, ask other owners of the same processor how it works for them in the same tasks. Often they bring computers to us and say: my video on the Internet has started to slow down. We look at why this is happening and find out that the new video codec old cpu does not pull. We explain this to the client, but he does not believe and motivates this by the fact that 2 weeks ago everything worked for him, but now it slows down. The problem was that the site on which he watched the video went but new method video encoding, which heavily loads older processors, but gives a better video picture.

Clogged autoload

Another trouble that occurs among inexperienced users, heavily clogged unnecessary applications autoload. After all these applications are loaded (the computer will be loaded for a very long time), they load the processor with their activity. Startup needs to be cleaned, you can even remove everything from there except for the antivirus and the programs that you really use. You can do this through the program in the startup section or in the search, write MSCONFIG and go to the startup section and disable unnecessary.

Antivirus activity

The hard drive is loading the processor

The hard drive under some conditions can load the processor up to 100%. Most often this is due to the fact that the disk begins to fail. I wrote about this in detail in the article -. Follow all the recommendations and you may stop loading the disk and the processor up to 100%.

Problems with peripheral equipment

Disconnect everything from your laptop or PC, leave the bare minimum (mouse, keyboard, monitor). Then connect everything desired devices take turns and check the reaction of the processor. Perhaps this way you will find the culprit of this problem. I also recommend paying attention to the device manager, whether there will be installed devices with yellow or red icons, this means either there are no drivers or they are not working properly. As I wrote above, this can create a load on the percent.

Huge number of running processes

Everything can be simple and trite, maybe you just launched too many applications at the same time and the processor simply does not pull it all. The processor can be powerful, but everything has a limit. Open Task Manager (CTRL+ALT+DEL) sort processes by CPU load and stop/disable the heaviest processes. If you don’t know which process is responsible for what, you can look up information on the Internet. I'll show you more in the video on this page.

Some processes cannot be tracked through a regular task manager (these may be virus processes), then download and check all processes with it, you can also check the process for digital signature, as well as viral activity!

Svchost.exe loads the processor!

With the svchost.exe process, not everything is so simple, there are 2 options, either it is viral activity or the system process really loads the processor. If the load is created by a virus process, then most often it can be seen through Process Explorer, it will be launched from the admin or from your account. It is enough just to stop the process and clean up the viruses. If svchost.exe is really a system process, then try disabling automatic Windows updates in services and also try turning off your antivirus, it may conflict with other software.

In the vastness of Runet, I found another one interesting way, but you can use it only at your own peril and risk! Find Prefetch folder, located under C:\WINDOWS\Prefetch and delete it. Then find the Tasks folder (C:\WINDOWS\system32\Tasks), open it and delete all files from it. Now start the task manager, delete the entire svchost.exe task tree, and then restart the computer. I talked about this folder in the article about the load on the screw.

PSU power shortage

Well, the last thing that can cause an unnatural load on the processor is the power supply. If the PSU supplies insufficient power to the computer, then the processor can be loaded up to 100% of simple tasks. I recommend checking the PSU and all the hardware of the computer by.

Do you have a constantly loaded processor and your computer or laptop slows down a lot? And at the same time - in idle mode? High CPU usage ( CPU) is one of the most common problems today. And it is constantly faced by PC and laptop users.

These tips are universal, so you can apply them to Windows 7, 8, 10 and XP. The processor model on a laptop or computer also does not really matter.

What program is loading the processor

First you need to start the manager and see how much the processor is loaded on your PC. To do this, press Ctrl + Shift + Del and pay attention to the “CPU Usage” item (it is located at the bottom).

In principle, this value can jump. But not much. For example, for Core i5 in idle mode (or when the browser is on), it loads by 2-8%. And this is the norm. Although on weak processors (for example, 2-core Core 2 Duo), the load can already be 10-20%. Here everything depends on specific model CPU installed on a computer or laptop.

If the processor is loaded at 50 or 100 percent, then this is clearly overkill. To see why the processor is so busy on Windows 7, go to the "Processes" tab, and then click on the "CPU" box. This will sort the list in descending order.

The screenshot below shows that the CPU loads only the plugin Flash Player(because of the included browser). But not much, so this case it's not critical.

By the way, quite often the following situation arises: you played a game or worked in a program, and after a while closed it. But the process itself may still be active. It turns out that you no longer play and do not work, but the program still loads your processor. In this case, you need to go to the manager and manually end the process. Or just restart your computer.

Also, be sure to pay attention to unknown processes due to which the processor is loaded at 50 percent (or higher). Especially if you see them for the first time, and they load the CPU by at least 20%. It is possible that these are viruses.

What to do if the processor is loaded for no reason

Didn't find any processes in the manager, and the CPU is still heavily loaded in idle? To get started, you can click the "Display processes of all users" button. This usually does not help, but it is possible that new items will appear in the list.

And to display all the processes due to which the CPU is constantly loaded, it is recommended to use free program. Using it is very simple:

  1. Run the utility.
  2. Click on the "CPU" column to sort processes in descending order of load.
  3. See why the processor is heavily loaded.

The screenshot above shows that the Interrupts process (system interrupts) is to blame. It is he who loads the processor by 18% in idle mode. Although it can load 50 and even 100 percent!

Fixing a problem like this is extremely difficult. And all because such a large CPU load can occur due to:

  • drivers on a computer or laptop;
  • viruses;
  • wrong mode of operation hard drive;
  • problems with peripheral equipment (printers, scanners, HDD drives, etc.).

Most often, heavy CPU usage occurs due to drivers. To check this, and see if there is any CPU load. If not, then most likely the problem lies precisely in the drivers.

The easiest way to fix it is. And then install the drivers on a computer or laptop one by one and check the CPU load after each of them. That way you can quickly find the culprit.

Usually this problem appears due to the universal Microsoft drivers that are installed immediately after installing a new Windows. In this case, it is better to find required drivers at office manufacturer's website and install them. Read more about how to do this here:

And it will not be superfluous to use special tools for searching malware And advertising viruses(adware, malware).

Incorrect operation of the hard drive can also affect the fact that the process will be heavily loaded. Especially if it works in PIO mode (DMA mode must be set). This must be checked and corrected if necessary.

And the last reason why system interrupts and high processor load occur is problems with printers, scanners and other peripheral equipment. To check this, turn off all devices and leave only the mouse and keyboard.

Also go to Start - Control Panel - Device Manager and see if there are devices here that have a yellow exclamation mark next to them. Its presence indicates that the equipment is not working correctly and you need to update the driver (which you need to do).

CPU is constantly 100 percent loaded in Windows 7

There is another fairly common problem that often occurs on Windows 7. It consists in the fact that on many PCs and laptops the processor is constantly loaded at 100 percent in idle mode (i.e. even on the desktop). And if you open the task manager, then you can see the svchost.exe process there, which is duplicated several times.

The reason here lies in the automatic updating of Windows 7. The fact is that updates are now being released only for Windows 8 and 10. Of course, they are not suitable for Windows 7, and therefore do not work correctly. It is for this reason that on Windows 7 the processor is loaded at 100 percent.

To fix this, you just need to turn off automatic updates. For this:


After that, the svchost.exe process should disappear, and with it the CPU load will decrease.

Overloading the processor of a computer or laptop can be caused by a number of reasons - from technical obsolescence of hardware to viruses that load the system.

By itself, high CPU usage is not a problem. All resources can be used up when running games, ultra-high quality videos, video editing applications, archivers, antivirus checks. First of all, you need to check whether the processor is really overloaded or the cause slow work there were other problems.

Press Ctrl+Shift+Esc to open Task Manager and click on the CPU column to sort. You can also get into the dispatcher by pressing Ctrl + Alt + Del and selecting the desired item in the menu that appears.

Normally, the to-do list should look something like this. When the load is high, one or more tasks will take up most of the processor time. If one of the applications takes 50-100% of the power for itself constantly, this may be a symptom of a problem.

For example, in the screenshot, almost half the power of the i5-2500k processor is occupied by the "Task Manager" and system interrupts, which should not be.

Hardware causes of overload

Despite the common misconception, it is rarely the cause of processor overload. The processor is more likely to take the system into a reboot or freeze completely than to work at 100% power for a long time. However, such cases sometimes occur and the user needs to know how to protect themselves from them.

Legacy equipment

The most common cause of processor overload is the obsolescence of a PC or laptop. Software does not stand still: if five years ago for comfortable work Google Chrome a single-core processor with a couple of hundred megabytes was enough random access memory, then now several heavy tabs can use the resources of several cores and several gigabytes. In 2018, a 4-core processor with 6-8 gigabytes of memory will be required for comfortable work.

If there is no money for new hardware, try to follow these tips:

  • do not run multiple applications at once. This not only makes it difficult for the processor to work by itself - RAM filled to capacity creates additional load;
  • use older versions of programs whenever possible. Yes, it can be inconvenient and insecure, but older versions of applications will be much less demanding;
  • disable unnecessary services and programs in startup. This can be done in the "Startup" and "Services" tabs of the "Task Manager";
  • try to avoid situations in which the processor will be loaded at 100% unnecessarily. For example, don't open a lot of browser tabs or 4K videos on a small laptop screen.

Overclocking

The next situation that can cause overload is overclocking or overclocking. There is nothing wrong with overclocking the characteristics of devices in itself, everything major manufacturers provide programs for adjusting the frequencies of the processor and video card. However, exceeding the allowed limits for the processor can lead to:

  • overheating;
  • image artifacts;
  • application errors and crashes;
  • freezes;
  • 100% CPU usage for trivial tasks.

Here, for verification, you should use diagnostic utilities that write the results to the log. For detailed statistics on all components, MSI Afterburner is suitable.

CPU overheating

By itself, high temperature rarely causes overload directly, much more often it disables the processor or triggers mechanisms that reduce frequencies and voltage on the device to protect it. on the sensors can be viewed in AIDA64.

How to solve the problem with overheating?

  • clean the body system block from dust. Pay special attention to the heatsink and CPU fan. For a laptop, the cleaning procedure should be carried out at least once every one and a half to two years;
  • If the computer has been in use for two years or more, remove the thermal paste between the fan and processor cover. Apply a new even layer;
  • in the case when standard cooling does not cope or the cooler does not work - replace it with a more powerful one. Preferably with massive aluminum radiator with copper pipes;
  • do not block the ventilation holes of the system unit when replacing it.

Note! The normal temperature of a working processor is about 40 degrees, at 70-80 degrees the BIOS protection mechanisms are activated.

Software overload causes

It is much easier to get 100% load on the processor by software than by hardware - you just need to make a mistake in the antivirus check settings or download an incompatible one. new system program.

Antiviruses and viruses

Of the entire list of causes of possible problems leading to 100% CPU usage, most often problems arise with antiviruses. Real-time file checks are a resource-intensive task that, if not properly configured, can take forever.

On the weak computers Installing a cloud-based antivirus like Panda Cloud Cleaner will help. It is much more demanding on the quality of the Internet, but the load on the processor is minimal.

In Windows 10, you can use the built-in Defender, which is quite enough for home tasks.

The other side of the coin is viruses on an unprotected PC. Malicious programs can use your computer for mining or as a gateway for DDOS attacks. For a one-time cleaning of existing problems, use Dr.Web Cureit!

Automatic update

An overload could be caused by a failed update operating system or drivers. Such problems happened in 2015 for users of beta versions of Windows 10. To solve the problem, try installing different versions drivers, roll back updates through a system restore point, or disable them completely.


In Windows 10, disabling updates has no visible effect of overload protection.

Background apps

A number of programs to support their functionality runs in the background. For example, Skype and LibreOffice are constantly in RAM, for fast loading. In some situations, this can become a problem - for example, when a program hangs in the background, which takes up from half to all of the computer's resources.

Disable background application you can also in the "Task Manager" if you hover the mouse cursor over the selected running application and use the "End task" button.

Video - CPU usage 100 percent, what to do on Windows 7,8,10?

Hello.

One of the most common reasons why a computer slows down is processor load, and sometimes incomprehensible applications and processes.

Not so long ago, on one computer of a friend, I had to deal with “incomprehensible” CPU usage, which sometimes reached 100%, although there were no programs that could load it that way (by the way, the processor was quite modern Intel inside Core i3). The problem was solved by reinstalling the system and installing new drivers (but more on that later ...).

Actually, I decided that this problem is quite popular and will be of interest to a wide range of users. In the article I will give recommendations, thanks to which you can independently figure out why the processor is loaded, and how to reduce the load on it. So…

1. Question number 1 - what program is the processor loaded with?

To find out how much the processor is loaded, open the Windows Task Manager.

Buttons: Ctrl+Shift+Esc (or Ctrl+Alt+Del) .

By the way, very often the problem arises of the following plan: you worked, for example, in Adobe Photoshop, then they closed the program, but it remained in the processes (or this happens all the time with some games). As a result, they “eat” resources, and not small ones. Because of this, the computer starts to slow down. Therefore, very often the first recommendation in such cases is to restart the PC (because in this case such applications will be closed), or go to the task manager and remove such a process.

2. Question number 2 - there is CPU usage, applications and processes that load - no! What to do?

When setting up one of the computers, I encountered an incomprehensible CPU load - there is a load, there are no processes! The screenshot below shows how it looks in the task manager.

On the one hand, it is surprising: the “Display processes of all users” checkbox is enabled, there is nothing among the processes, and the PC load jumps 16-30%!

To see all processes that load the PC - run free utility Process Explorer. Next, sort all the processes by load (CPU column) and see if there are any suspicious "elements" there (task manager does not show some processes, unlike Process Explorer).

Link to office Process Explorer site: https://technet.microsoft.com/en-us/bb896653.aspx

Process Explorer - load the processor by ~ 20% system interrupts (Hardware interrupts and DPCs). When everything is in order, usually, the CPU usage associated with Hardware interrupts and DPCs does not exceed 0.5-1%.

In my case, the culprit was hardware interrupts and DPCs. By the way, I’ll say that sometimes fixing the PC load associated with them is quite troublesome and complicated (besides, sometimes they can load the processor not only by 30%, but by 100%!).

The fact is that the CPU is loaded because of them in several cases: problems with drivers; viruses; HDD works not in DMA mode, but in PIO mode; problems with peripheral equipment (for example, printer, scanner, network cards, flash and HDD drives, etc.).

1. Problems with drivers

The most common reason for CPU usage system interrupts. I recommend doing the following: boot the PC in safe mode and see if there is a load on the processor: if it is not there, the reason is very high in the drivers! In general, the simplest and fast way in this case is to reinstall Windows system and then install one driver at a time and see if CPU usage appears (as soon as it does, you've found the culprit).

Most often, the fault here is network cards + universal drivers from Microsoft, which are installed immediately when you install Windows (sorry for the tautology). I recommend downloading and updating all drivers from the official website of your laptop/computer manufacturer.

Plus check your computer sometimes third party programs(who are looking for adware, mailware, etc.): about them in detail.

3.Mode work hard disk

Mode HDD work It can also affect the loading and speed of the PC. In general, if the hard drive does not work in DMA mode, but in PIO mode, you will immediately notice this with terrible “brakes”!

4. Problems with peripheral equipment

Disconnect everything from your laptop or PC, leave the bare minimum (mouse, keyboard, monitor). I also recommend paying attention to device Manager, whether there will be installed devices with yellow or red icons in it (this means either there are no drivers, or they do not work correctly).

How to open device manager? The easiest way is to open the panel Windows controls and drive into search string the word "dispatcher". See screenshot below.

Device manager: there are no drivers for devices (disk drives), they may not work correctly (or most likely not work at all).

3. Question number 3 - overheating and dust can be the reason for loading the processor ?!

The reason why the processor can be loaded and the computer starts to slow down is that it may be overheating. Usually, the characteristic signs of overheating are:

  • increased cooler hum: the number of revolutions per minute increases because of this, the noise from it is getting stronger. If you have a laptop: then swiping your hand next to the left side (usually there is an outlet for hot air on laptops) - you can notice how much air is blown out and how hot it is. Sometimes - the hand does not tolerate (this is not good)!
  • braking and slowing down the computer (laptop);
  • refusal to boot with errors reporting failures in the cooling system, etc.

For example, in the AIDA 64 program, to view the processor temperature, you need to open the " Computer/sensor«.

AIDA64 - processor temperature 49gr. C.

How to find out what temperature is critical for your processor and what is normal?

The easiest way is to look at the manufacturer's website, this information is always indicated there. It is rather difficult to give general figures for different models processors.

In general, on average, if the temperature of the processor is not higher than 40 gr. C. - then everything is fine. Above 50gr. C. - may indicate problems in the cooling system (for example, an abundance of dust). However, for some models of processors, this temperature is the usual operating temperature. This is especially true for laptops, where due to limited space it is difficult to organize good system cooling. By the way, on laptops and 70 gr. C. - may be normal temperature under load.

Dust cleaning: when, how and how many times?

In general, it is advisable to clean a computer or laptop from dust 1-2 times a year (although a lot depends on your premises, some people have more dust, some less ...). Once every 3-4 years, it is advisable to replace the thermal paste. Both operations are not difficult and can be performed independently.

In order not to repeat myself, I will give a couple of links below ...

How to clean the computer from dust and replace the thermal paste:

Cleaning a laptop from dust, how to wipe the screen:

PS

That's all for today. By the way, if the measures suggested above did not help, you can try to reinstall Windows (or even replace it with a newer one, for example, change Windows 7 to Windows 8). Sometimes, it is easier to reinstall the OS than to look for the cause: you will save time and money ... In general, sometimes you need to do backups(when everything works well).

Good day!

I think that almost every user, at least with little experience, has encountered a similar problem: you work and work at the computer, and then you start to notice that it somehow slowly reacts to pressing the mouse buttons, keyboard, slows down ...

Very often the reason for slow work and brakes is the CPU load, sometimes it reaches 100%!

Solving this problem is not always easy, especially since the CPU can be loaded for no apparent reason (that is, you may not have run any resource-intensive programs: games, video editors, etc.).

In this article, I will consider a sequence of actions that can be taken to remove CPU usage and return the computer to normal performance.

The first thing to try is to identify the process or program that is using the CPU. As happens in most cases: some program (or game) was launched, then the user left it, and the process with the game remained, which loads the processor ...

What process, program loaded the processor

The fastest way to determine which program is using the CPU is to call Task Manager(buttons: Ctrl+Shift+Esc ).

In Task Manager, open the Processes tab and sort applications by CPU usage. In the screenshot below, you can see that the lion's share of the CPU (~ 84%) is eaten by Firefox browser(Although I don't even have it running...). If you have such a "hidden" program, then you can immediately close it from the task manager (just right-click on it ...).

Note

Windows has its own resource monitor, which can also be used to view CPU, memory, disk, and network usage. To call it, press the buttons Win+R, then type in the line "Open" command resmon and press Enter .

Important!

In some cases, the task manager does not allow you to calculate the reason for the processor load. By the way, the processor can be loaded not at 100%, but, say, at 20-50%...

If the task manager did not give information for consideration, I recommend using one utility - Process Explorer(by the way, located on the Microsoft website...).

Process Explorer (search for the "invisible" cause of the brakes)

An excellent program that has helped me more than once! Its main direction of work is to show you ALL the processes and programs running on the computer (probably no one will leave her ...). Thus, you can determine for sure which process is consuming the CPU.

The screenshot below is very revealing:

  • system idle process is a measure in % of system inactivity. Those. in the first half of the screen below - the processor is almost 95% idle (this is exactly how it should be if a couple of programs are open on it: a browser, a player);
  • and on the second part of the screen system idle process is 65%, but hardware interrupts and DPCs as much as 20% (and sometimes even up to 70-80%! This should not be. In general, interrupts (these are system interrupts) during normal operation rarely go beyond a few percent! That's the reason for the brakes and loading the computer!
  • by the way, very often the system is loaded by the svchosts.exe process. In general, this is a system process, but there are a number of viruses that disguise themselves as it and impersonate it. Below we consider the question of how to catch them ...

Process Explorer: on the first part of the screenshot - everything is fine, on the second - the processor is loaded by ~20% with hardware interrupts and DPCs.

If the CPU is loading interrupts...

If the problem is related hardware interrupts and DPCs- then most likely the problems are related to the drivers. More precisely, with their conflict with each other, and even more likely, with incompatibility with your Windows OS. Moreover, even if the description for the driver says your Windows version- this is not a 100% guarantee of compatibility.

Pay special attention to drivers: video cards, chipset mat. boards, network cards, Wi-Fi, sound card. I recommend downloading several versions at once and trying them one by one.

Less commonly, the problem is associated with viruses, even less often with peripheral equipment: a printer, scanner, network cards, etc.

Checking and updating drivers

Sometimes finding the right drivers for your computer / laptop is not as easy as it seems at first glance ... In general, usually, a new version driver works better than the old one (but sometimes everything is exactly the opposite). If your CPU usage is related to hardware interrupts and DPCs- I recommend:

  1. try installing drivers from the official website of your hardware manufacturer. Usually, this requires determining the manufacturer - for this you can use special. utilities for determining the characteristics of a PC - ;
  2. if you did not find the site or could not determine the manufacturer, you can try to use some special. driver update utility:
  3. if during installation there were problems with removing the old driver from the system, I recommend this instruction:

To find out if you have devices in your system for which there are no drivers - open device Manager . To do this, call the "Run" menu - buttons Win+R, enter devmgmt.msc(example on screenshot below).

Virus Scan

Viruses - can be the cause of anything ... Usually, when the processor is loaded due to viruses - you can find some process that loads the system. Most often, this process is systemic: for example, viruses disguise themselves as a process svchost.exe- even a user with experience can not immediately find and identify among real processes, a virus one (but this file will be discussed below) ...

  1. In Windows Xp, 7 - you can press the F8 key several times during boot - a "black" window should appear with a choice of boot options;
  2. in Windows 8, 10 - click Win+R, enter the command msconfig. Further in the section select Windows OS and check the box next to the item "Safe mode" . Save settings and restart PC (screenshot below).

And already from safe mode, it is advisable to run a virus scan. For this, it is not necessary to have on the computer installed antivirus- eat special utilities that do not need to be installed.

Periphery equipment

If the problem has not yet been found, I recommend trying to disconnect everything unnecessary from the laptop (computer): printer, scanner, mouse, etc.

I will also focus on device manager (more precisely on the drivers). It is possible that for some peripheral equipment the drivers are not installed in the system and the exclamation mark is on ...

Pay special attention to old devices that may work in the new Windows OS, but you installed the drivers for them "forcibly" (for example, Windows could warn that there was no signature, and you continued the installation) ...

In general, it is quite difficult to find the true culprit in this case. If the processor is not loaded in safe mode, I recommend trying to remove the drivers one by one on periphery equipment and see how the load behaves.

How to remove old or extra "firewood" -

Svchost.exe loads the processor - what is it?

Very often loads the processor file svchost.exe- at least that's what he says. Task Manager. The point is that this is the main process for loading services - i.e. Roughly speaking, the necessary system process, without which you can not do ...

There are two cases here:

  • viruses are often disguised as this process, and to distinguish real svchost from masquerading - even experienced users are not always able to;
  • real svchost can load the system in certain cases.

How to determine which svchost.exe file is system and which is not?

When you run it, you need to go to the menu Service/Process Manager (see screenshot below). Next, you will see ALL processes in the system - they need to be sorted by name (it's more convenient, it seems to me).

The bottom line is: all system processes that AVZ knows about are marked green color. Those. if you have in the list svchost black colors - look at them very carefully, they are most likely viral.

By the way, with the help of this AVZ, you can analyze all other suspicious processes.

Disabling automatic windows updates

Often svchost loads the processor due to the included automatic update Windows. I suggest turning it off (there is nothing wrong with that - just a couple of times a month you will manually check for updates - 1-2 clicks with the mouse ...).

First you need to open the tab services. The fastest way to do this is to press the button WIN+R, enter services.msc and press Enter(as in the screenshot below).

  1. startup type set "Disabled";
  2. and click the "Stop" button.

Save your settings and restart your computer.

Is there overheating? CPU temperature check!

A possible reason for the processor load may be overheating. Moreover, if everything was fine with you before, this does not mean at all that now it cannot start to overheat.

The most common cause of overheating is:

  • dust(especially if the system unit has not been cleaned from it for a long time). Dust forgets the ventilation holes, the air begins to circulate poorly in the device case - and the hot air from the processor remains in place, and the temperature begins to rise. Most easy way get rid of dust - open the cover of the system unit and blow out the dust with a vacuum cleaner by turning on the reverse mode. With laptops, everything is more complicated - if you have never taken it apart before, I recommend giving it to specialists ...
  • high room temperature . Usually, this happens in hot weather in summer, when the temperature outside the window can rise significantly. In this case, you can open the side cover of the system unit - and send a regular fan in its direction. There are special cooling pads for laptops.
  • broken cooler (or he could also be clogged with dust). The advice here is simple - replace it or clean it.

Signs that you can suspect overheating:

To find out the temperature of the processor- I recommend using some utility to determine the characteristics of the PC. For example, I like Speccy and Aida 64. You can see a screenshot of the processor temperature from Speccy below (t=49 °C, degrees Celsius).

Utilities for viewing computer characteristics -

What should be the temperature of the processor?

A very popular question that cannot be answered unambiguously. The fact is that different manufacturers have different critical temperatures.

For personal computer

In general, the ideal option is to look at the model of your processor and open the manufacturer's website: critical temperatures are always indicated on it.

Generally speaking, if the temperature of your processor is up to 40 ° C (degrees Celsius), then everything is in order with it, the cooling system copes. Temperatures above 50 °C - may indicate problems in the cooling system (or a large number of dust). Everything above 60 degrees - you need to carefully review and take action: clean from dust, install additional coolers(or replace the old one).

For laptop

As for laptops, the bar is somewhat different here. Since the space in the laptop is limited, the processors here heat up higher. For example, it is not uncommon - the operating temperature in the load for many processors is about 70 ° C. When idle, this bar is usually around 40-50 °C. In general, it starts to worry (for most modern laptops) if the processor temperature rises above 75-80 ° C (at least check if this is normal for your device.

Most often, such a high temperature is reached when running editors, games, and other heavy applications.

By the way, many advanced users(and some experts) echo the critical 105 ° C for modern laptops. I will say this, the laptop can and will work at 90-95 ° C, and even, perhaps, at 100 ° C - but the main question is: how much? In general, the question is debatable for many ...

PS

Last tip. Sometimes finding and eliminating the causes of high processor load and computer slowdowns is a rather tedious and not easy task. In such cases, I recommend trying some with different OSes, or replacing your Windows 7 with, say, a better one. new Windows 8/10 - the problem can be solved with just a 10-minute reinstallation of the OS...

Well, that's all for me. Good luck!
