CPU usage 100 what to do. Why is the processor loaded and how to reduce the CPU load? Check and update drivers

Hello.

One of the most common reasons for which the computer slows down is loading the processor, and sometimes incomprehensible applications and processes.

Not so long ago, on one computer, I had to face the "incomprehensible" loading of the CPU, which sometimes reached 100%, although there were no programs that could not download it, it was not openly (by the way, the processor was quite modern Intel Inside Core i3). The problem was able to solve reinstalling the system and installing new drivers (but further ...).

Actually, I decided that a similar problem is quite popular and will be interested in a wide range of users. The article will give recommendations, thanks to which you can independently understand why the processor is loaded, and how to reduce the load on it. So…

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

To find out how much percent 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 the following plan: you worked, for example, in Adobe Photoshop., then closed the program, and it remained in the processes (or with some games so constantly happening). As a result, the resources are "eating", and not small. Because of this, the computer begins to slow down. Therefore, very often the first recommendation in such cases is to restart the PC (since in this case, such applications will be closed), well, or go to the task manager and remove such a process.

2. Question # 2 - Loading CPU There are applications and processes that ship - no! What to do?

When setting up one of the computers, I ran into the incomprehensible loading of the CPU - there is a load, there are no processes! Below in the screenshot is shown how it looks in the task manager.

On the one hand, it is surprising: the check mark "Display the processes of all users" is turned on, there is nothing among the processes, and the PC load jumps 16-30%!

To see all processes who ship PC - run a free utility Process Explorer.. Next, sort all the processes on the load (CPU Stage) and see if there are suspicious "elements" there (some processes of task dispatcher does not show, unlike Process Explorer.).

Link to office. Website Process Explorer: https://technet.microsoft.com/ru-ru/bb896653.aspx

Process Explorer - shipping processor for ~ 20% system interrupts (Hardware Interrupts and DPCS). When everything is in order, usually, the download of the CPU associated with Hardware Interrupts and DPCS does not exceed 0.5-1%.

In my case, the culprit was the system interrupts (Hardware Interrupts and DPCS). By the way, I will say that it is sometimes for the loading of a PC associated with them - the case is quite troublesome and complex (to that, sometimes they can ship the processor not only by 30%, but also 100%!).

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

1. Problems with drivers

The most common reason for loading the CPU systemic interrupts. I recommend to do the following: Download PCs in safe mode And there is no load on the processor: if it is not - it is very high the reason exactly in the drivers! In general, the easiest and fast way In this case, it is to reinstall the Windows system and then install one drive and watch, if the CPU load did not appear (as soon as it appears - you found the culprit).

Most often guilt here network cards + universal drivers from Microsoft, which are installed immediately when windows installation (I apologize for the tautology). I recommend to download and update all the drivers from the official site of the manufacturer of your laptop / computer.

Plus Sometimes Check Computer third-party programs (who are looking for advertising modules Adware, Mailware, etc.): About them in detail.

3. Mode of operation hard disk

The HDD operation mode can also affect the download and speed of the PC. In general, if the hard disk does not work in DMA mode, but in PIO mode - you immediately notice the terrible "brakes"!

4. Problems with peripheral equipment

Disconnect everything from a laptop or PC, leave the smallest (mouse, keyboard, monitor). I also recommend paying attention to device Managerwhether it will not be installed devices with yellow or red icons (this means either there are no drivers, or they work incorrectly).

How to Open Device Manager? The easiest way is to open the panel windows management And drive B. search string The word "dispatcher". See Screenshot below.

Device Manager: No Drivers for devices (disk drives), they can not work correctly (but most likely not to work at all).

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

The reason for which the processor can be loaded and the computer will begin to slow down - it may be overheating. Usually, characteristic signs of overheating, such:

• strengthening the roast of the cooler: the number of revolutions is growing due to this noise from it is still stronger. You had a laptop: I spent your hand next to the left side (usually there is organized on laptops a hot air output) - you can notice how much air is very blowing and how hot it is hot. Sometimes - the hand does not tolerate (this is not good)!
• braking and slowing down the computer (laptop);
• failure to download with errors to report failures in the cooling system, etc.

For example, in aIDA program 64 to see the temperature of the processor, you need to open the tab " Computer / sensor«.

AIDA64 - Processor temperature 49g. C.

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

The easiest way is to see the manufacturer's site, this information is always indicated there. It is quite difficult to give common numbers on different models processors.

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

Cleaning from dust: When, how and how many times?

In general, to brush the computer or laptop from dust 1-2 times a year (although much depends on your room, someone dust more, someone less ...). Once in 3-4 years it is desirable to replace the thermal paste. And the one and the other operation does not represent anything complicated and can be performed independently.

To not repeat, I will give a couple of references below ...

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

Cleaning a laptop from dust how to wipe the screen:

PS.

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

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

To check the overheating processor and look at the temperature of the processor without load and in the load. Compare these temperatures with the maximum permissible processor application. The maximum allowable temperature can be found on the processor manufacturer website in the specification.

Viral activity

When there are many viruses on a computer, it also reduces system performance. Viruses as conventional programs spend the processor resources, this may lead to 100% percentage load. I tell a lot about the removal of viruses on my youTube Canal And also be sure to read and follow. After complete cleaning the computer from viruses, there will be no problem with the processor load!

Problems with driver

Another reason for loading CPU is system interrupts, in other words, the problem with the drivers. I recommend to do the following: download the computer in safe mode and see whether there is an increased load on the processor. If there is no load - very high probability is that the reason is in the drivers, because the driver is not loaded safe mode! The only way to solve this problem, delete all the drivers and then install one drive and watch, if the CPU load did not appear as soon as the download went - you found the culprit.

Most often guilt here Network cards + Universal Drivers from Microsoft, which are installed immediately when Windows is installed. I recommend to download and update all drivers from the official site of the manufacturer of your equipment. How to do this I showed.

Elementally weak percent, which does not pull ツ

Many for some reason think that their ancient processor and today should pull everything normally and without brakes. But this is not the case, now digital technologies are developing very quickly and sometimes budget processors of only two or three years ago nothing is drawn today. Even if you have a top processor of 10 years ago, this does not mean that it can cope with modern tasks. Perhaps the strong load of your processor is precisely in this, think about it. If you are not sure to ask other owners of the same processor as it works in the same tasks. Compacts are often brought to us and say: I started to slow down the video on the Internet. We look at why it happens and it turns out that the new codec video old processor does not pull. We explain it to the client, and he does not believe and motivates it by the fact that 2 weeks ago he worked everything, but now slows down. The problem was that the site on which he watched the video moved but a new video coding method that greatly loads old processors, but gives a better picture of the video.

Scored by trash tapped

Another trouble that occurs at experienced users, badly 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. The autoload must be cleaned, you can even remove all from there besides antivirus and programs that you really use. You can do this through the program in the Startup section, or write msconfig in the search and go to the Startup section and disconnect the unnecessary one.

Antivirus activity

Hard disk loads processor

The hard disk under certain conditions can load the processor to 100%. Most often, this is due to the fact that the disk begins to fail. In detail about it, I wrote in the article -. Perform all recommendations and it will help you will stop loading the disk and processor up to 100%.

Problems with peripheral equipment

Disconnect everything from a laptop or PC, leave the smallest (mouse, keyboard, monitor). Then plug into everything design devices In turn and check the projects reaction. Maybe you will find the culprit of this problem. I also recommend paying attention to the device manager, whether it will not be installed devices with yellow or red icons, it means either there are no drivers, or they work incorrectly. As I already wrote above, it can create a load of percent.

Huge number of running processes

Everything can be simple and trite, perhaps 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 only has a limit. Open the task manager (Ctrl + Alt + Del) Sort the processes by load percent and stop / disconnect the most difficult processes. If you do not know which process for what is responsible can look for information on the Internet. Read more I will show you in the video on this page.

Some processes are not possible to track through the usual task manager (it can be viral processes), then download and check all the processes to them, you can also check the process on digital signature, as well as for viral activity!

Svchost.exe shipping processor!

With the svchost.exe process is not so unambiguous, there are 2 options or this viral activity is either system process And the truth is loading the processor. If the load creates a viral process, then most often it can be seen through the Process Explorer, it will be launched from the admin either with your account. It is enough just to stop the process and make cleaning from viruses. If svchost.exe is a real system process, then try to disable the automatic Windows update in the services and also try turning off the antivirus, it may conflict with another software.

On the expanses of Runet, I found another interesting waybut you can use it only at your own risk! Find the Prefetch folder, located in the C: \\ Windows \\ Prefetch section and delete it. Then find the TASKS folder (C: \\ Windows \\ System32 \\ Tasks), open it and delete all files from it. Now run the task manager, delete the entire SVCHOST.EXE task tree, after which you restart the computer. I told about this folder in the article about the load on the screw.

Power shortage BP

Well, the latter that can cause an unnatural load on the processor is a power supply. If the BP gives an insufficient nutrition to a computer, the processor can be loaded up to 100% of simple tasks. I recommend checking the BP and all iron computers.

Do you have a constantly loaded processor and slowly slows down a computer or laptop? And at the same time - in idle mode? A large loading of the CPU (CPU) is one of the most common problems. And the users of PCs and laptops are constantly colliding with it.

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

What program downloads the processor

First you need to start the dispatcher and see how much percent is loaded the processor on your PC. To do this, press Ctrl + SHIFT + DEL and pay attention to the "Loading CPU" item (it is at the bottom).

In principle, this value can jump. But not much. For example, at Core i5 in idle mode (or when the browser is enabled) is loaded by 2-8%. And this is the norm. Although on weak processors (for example, 2-nuclear Core 2 DUO) load can already be 10-20%. It all depends on the specific CPU model installed on the computer or laptop.

If the processor is loaded by 50 or 100 percent, then it is clearly busting. To see why the processor is so much loaded on Windows 7, go to the Processes tab, and then click on the CPU field. It sorts the list in descending order.

In the screenshot, it is clear that the CPU loads only the plugin Flash Player. (due to browser included). But not much, so in this case it is not critical.

By the way, the following situation arises quite often: you played the game or worked in the program, and after some time they closed it. But the process itself may continue to be active. It turns out that you are no longer playing and do not work, but the program will still ship your processor. In this case, you need to go to the dispatcher and manually complete the process. Or just restart the computer.

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

What to do if the processor is loaded without reasons

Did not find any processes in the dispatcher, and the CPU is still very loaded into a simple? To begin with, you can click the "Display All User Processes" button. It usually does not help, but perhaps the list will appear new items.

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

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

In the screenshot, it is clear that the interrupts process all wines (system interrupts). It is he who loads the processor by 18% in idle mode. Although it can ship by 50 and even 100 percent!

It is extremely difficult to correct this problem. And all because such a large load of the CPU may arise due to:

• drivers on a computer or laptop;
• viruses;
• incorrect hard disk mode;
• problems with peripheral machinery (printers, scanners, HDD drives, etc.).

Most often, the strong loading of the central processor arises due to drivers. To check it out, and see if there is a load on the CPU. If not, then, most likely, the problem lies precisely in the drivers.

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

Usually this problem appears due to the Universal Microsoft Drivers, which are put immediately after installing the new Windows. In this case, it is better to find the necessary drivers on your own. The site of the manufacturer and install them. For details on how to do it, read here:

And at all will not be superfluous special utilities To search for malicious programs and promotional viruses (Adware, Malware).

Incorrect hard work The disk can also affect the fact that the process will be strongly loaded. Especially if it works in PIO mode (DMA mode must be set). This must be checked and correcting if necessary.

And the last reason, due to which system interrupts arise and a large processor load - problems with printers, scanners and other peripheral equipment. To check this, disable all devices and leave only a mouse and keyboard.

Also go to the Start - Control Panel - Device Manager and see if there are devices here, near which yellow exclamation point. Its presence says that the equipment works incorrectly and you need to update the driver (which you need to do).

The processor is constantly loaded by 100 percent in Windows 7

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

The reason here lies in the automatic windows update 7. The fact is that updates are now released only for Windows 8 and 10. For Windows 7, they, of course, are not suitable, and therefore they work incorrectly. It is for this reason that on Windows 7 processor loads 100 percent.

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

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

The computer is scary inhibits, there is a long load (reboot) of Windows. CPU Uploaded 100 percent. Cooler (fan) buzzing and does not have time to cool the CPU. The sound in the columns can be very distorted wheezing, pull, rude. :)

However, if you open the task manager and look at the "Speed" tab, most likely we will see the loading of the CPU 100%. The dispatcher does not open, it means it is blocked by a virus and you need to unlock the dispatcher.

What to do? If you briefly install the security task manager, reveal the brake process, remove the malicious software that creates the limit 100% CPU load.

100 Processor loading

There is strong braking and after multiple installations and removal different programs, in the course of a long, or very use of PC. And as a rule, it is treated in most cases, neither tormenting herself, computer dangerous experiments over the registry, reinstalling windows systems. This is of course the extreme measure and yet ... Yes, this happens, but neither always 100% CPU.

This happens when it gets into a malicious software, which is very, very often happens. The computer sharply refuses and this happens, mainly when it is possible to load it (reboot), after activating the virus. If in the first case and tupits, but the processor is not so loaded and it is still possible to work on the PC, then if you get into and activate such a pest, perform any actions on the computer, almost impossible.

100% CPU - Virus

To identify such guests creating 100% processor load, there is a very good utility. Not bad say because they themselves got into such a situation and she helped out :)

Download!
SECURITY TASK MANAGER

Security Task Manager - security task manager displays the level of possible danger of a process. That is, it finds and shows all that not only interferes when downloading OS, but also to work properly Windows (y) (in her opinion). And you decide why you yourself need, and what is not. If the program is in the risk area in the first position, and you did not install it and do not know what it is, to delete immediately.

Install the manager and remove the Malicious Merchant Merchanting CPU.

One of the numerous troubles that you have to face windows usersIs loading CPU by 100 percent. With such a high load, the operating system is extremely slowly responded to the teams and work with it becomes at least uncomfortable. There are not so many problems that lead to such behavior, and their decision makes are sufficient.

The most likely reason why the CPU is loaded by 100%, the background work of programs becomes. It is often possible to find a situation where the resource-intensive application with which the user has worked is not completely unloaded from the memory. To some extent, this can be considered a variety of "hanging". The difference is that the program "hung" does not allow to close its "window" and does not respond to commands. In this case, the "window" closes, but the process remains in random access memory. The computer considers such a program to work and continues to allocate computing resources for it. As a result, the processor is loaded by 100 percent with the visual absence of launched tasks.

Windows 7 Task Manager

So, let's see what to do in Windows 7, facing such a problem. Microsoft gives us a full-fledged OS process management tool. To take advantage of them, it is enough to call context menu On the taskbar.

Select the item marked in the screenshot to start the dispatcher.

Open the "View" point in the top menu and go to the marked position.

To quickly calculate the "culprit", mark the specified points. Now our dispatcher is ready for use. Window parameters are remembered, so next time additional settings No need.

We turn on the sorting on the CPU column, which displays the load percentage. "The culprit" can be seen immediately. In this case, this is an archiving program that consumes half system resources. Choose a process and click the button circled in the screenshot to complete its operations.

Confirm your actions, and the resources consuming the program stops working. Thus simple way You can quickly reduce the downloads of the CPU in Windows 7.

Windows 10 Task Manager

IN latest version Microsoft has expanded the capabilities of the task manager. Added to it useful toolWhen working with which you can reduce the download of the CPU in Windows 10.

We use the indicated tab "Auto-loading" to bring order in applications starting with the operating system and reduce the loading of the CPU. In some users, in this place, you can find a real "zoo" from programs. At the same time, more than half of the automatically launched software is not used. For example, turn off the ONEDRIVE service. Few people keep in it, and its system is influenced as high. Thus, it is possible to make less CPU workload in Windows 10 on an ongoing basis. A disconnected service will not start when starting and take out computing resources.

System infection

A large loading of the CPU may be a direct consequence of the damage to a malicious product. Immediately makes itself felt only virus-extortionist. The most interesting representatives of this "fauna" will use a computer for their own purposes. Options can be quite a lot, from the banal distribution of spam to participation in the bot-network and trendy recently mining cryptocurrency. As a result, the processor is constantly loaded by performing unauthorized actions by a user.

Not every such "guest" can be timely detected by an antivirus program. In this case, healthy suspicion and utilities can come to the rescue, allowing you to get exhaustive information On the processes occurring in the system. Task Manager can show such information, but it's not so easy to understand it. For example, the presence of SVCHOST processes in the working OS is considered the norm provided they are running on behalf of the system.

The screenshot shows the work of the Process Explorer utility, references to which even Microsoft Technical Support. All processes are derived as tree structure With a show of mutual dependencies. When using it, the chances of identifying a masking malicious process have any attentive user.

Loading a 100 percent processor on Windows 10 or 7 may be a consequence of the reverse process. Overly worried about security PC owner sets several antivirus softwarewhich are starting to conflict using all available resources for this.

System Services

When updating to Windows 10 problems, users can deliver the MODERN SETUP HOST process. This system service is responsible for updating from old operating systems. At the same time, a complete copy of the existing OS is created on the system disk to provide the ability to "roll back". Its average size is about 20 GB and in the absence of this space, the service must interrupt the update. In some cases, its improper work can lead to a process hang and an increase in the load on the CPU. The problem is solved by manual liberation of the required space.

If the computer is not connected to the Internet, lower the CPU load on Windows 7 or 10, it is possible to disconnect unused services. Operating system By default, it starts services related to network work. For example, on local computer No service needed automatic update. Its work in the absence of an Internet connection is also able to lead to an uncontrolled load growth.

Finally

The vast majority of cases associated with increased loading of the CPU depend on software. Try not to mix the working and game configuration, turning the computer to the "Polygon" for testing. Valued set required programs Allows you to ensure the stability of the OS and avoid unnecessary failures.
