Every time you boot operating system The Chkdsk utility starts automatically. This utility scans your HDD for errors and possible failures in the file system. Of course, there is nothing wrong with this, but the system boot speed will decrease. Meanwhile, this procedure can be disabled, thereby increasing the OS loading speed.

You will need

• - a computer with Windows OS.

Instructions

To disable scanning of the system disk, follow these steps. Click Start. Select All Programs, then Accessories. Among the standard programs there is “Command Line”. Launch it.

Next, at the command line, enter Chkntfs /X C, where C is the system drive letter. If your system drive has a different letter, then, accordingly, you need to register it. After entering the command, press Enter. Close command line. Automatic scanning of the system partition is now disabled. In the same way you can disable automatic check other sections hard drive. Just at the end of the command you should write the letter of the hard drive partition for which you want to disable scanning.

Another way to turn off check- This is to edit the system registry branch. At the command prompt, enter regedit. After a second, the Registry Editor window will open. On its left side there is a list of the main sections of the system registry. Find the HKEY_LOCAL_MACHINE section among them.

Click on the arrow next to the name of this section. Repeat the procedure near the SYSTEM subsection. Thus, open the sections in this order: CurrentControlSet/Control/Session Manager. There is no need to open Session Manager; select it with a left mouse click.

After selecting the last section, branches for editing will be available in the right window. Find among them the branch called BootExecute. Double-click on it with the left mouse button. Now you can edit it. All you need to do is add the /K:C option before the asterisk. Ultimately, the edited branch will look like this: autocheck autochk /k:C. Save your changes. After this, disk check will be disabled.

The process of installing a processor depends on its type and configuration. motherboard. The main thing is to observe the principle of compatibility, as well as basic accuracy.

Instructions

Start the installation process by opening system unit and removing the motherboard, to do this, unscrew all the necessary mounting screws.

Study the motherboard model, visually remember how the processor is installed in a particular case. If the task is to replace an old stone with a new one, then before performing this replacement, explore the possibility of an upgrade. The motherboard must support the processor type. In order to find out this information, you can go to the manufacturer’s official website and read what configuration is possible.

1. Open Task Manager. To do this, use the keyboard shortcut ++, and then select “Open Task Manager”.
2. In the window that appears, select the “Processes” tab and sort the list by clicking on the “CPU” column header.
3. If in this moment There is no work running on your PC, then none of the processes will have a high load on the CPU. So, try to find the process that is loading the CPU. If you don’t find one in the list, then most likely there is a virus on your computer, since malware can hide from the task manager.
4. Run a virus scanner to find the virus.

High CPU usage due to startup programs

We are looking for useless programs that automatically start when the operating system starts

It is possible that high CPU load is caused by programs that automatically start with Windows.

1. Repeat steps 1 and 2 from the previous paragraph to open Task Manager under the Processes tab.
2. Find processes that are particularly CPU-intensive.
3. Press the +[R] keys and enter the command “msconfig” in the window that opens.
4. Go to the Startup tab and see if there is a process there that is currently taking a lot of load
5. You can exclude it from the list of programs that automatically start when Windows starts by unchecking the checkbox to the left of the process name. But be careful: you cannot remove antivirus software from the list of automatically launched programs. software and a backup utility. That being said, of course, sometimes they will take up a significant portion of your computer's performance.

High CPU usage due to svchost.exe

We are looking for svchost in the AppData folder

Due to incorrect installation of libraries in AppData, a meaningless but CPU-intensive process may start: svchost.exe. It should not be confused with svchost.exe, which belongs directly to Windows.

1. Repeat the first and second steps from the previous paragraph.
2. If the “svchost.exe” process is at the top, do the following.
3. Press the +[R] keys and enter the command “%appdata%” in the window that opens.
4. Find the folder called “dll” in the Explorer window that appears and delete the “svchost.exe” file, if it exists.
5. As an alternative, you can download the WinFuture program, as high CPU load may be caused by errors in the operating system update function.
6. Help in this matter is offered by the WinFuture Update Pack utility, which you can download as in full version, and as an upgrade.

The ultimate solution: more performance thanks to the new CPU

If all of the above tips don't help, there's a chance that your CPU is simply too old and weak for Windows 7. In that case, you'll need to consider getting a new CPU.

• Of course, it shouldn’t just be an Intel i7 for 80,000 rubles. In our you can find good processors entry level, which cost even less than 2000 rubles.
• For gamers and users who work with graphics, it makes sense to take a closer look at mid-range models. These include, for example, which costs less than 15,000 rubles.

To get even more information about the processes running on your computer, you can use the “Extended Task Manager” utility. Also, before you start looking for a solution to the problem, you should check if the "Balanced" or "Energy Saver" modes are selected in the "Power Options" instead of "High Performance".

After using the system for a long time, it begins to slow down, and various kinds of problems arise that users are not always able to solve. One of the main reasons for a slow PC is the CPU utilization at 100 percent. And it’s not always clear why this problem arises.

There are two reasons - hardware room And software. The second, of course, appears much more often, so we’ll start with it. There could be viruses, unknown processes, anything. In this article I will try to help you understand the CPU load at 100%.

If there is a suspicion that the processor is loaded at 100 percent

Go to Device Manager (keyboard shortcut Esc+Shift+Ctrl) and go to the tab "Performance". In the CPU section there is a graph that will let you know how much the processor is loaded, as well as a line "Usage". If the load is still 100 percent, then it is worth taking action.

Software type problem

When you open the task manager, you need to find the process that is using the processor. This can be done by any program installed on a PC, or by a virus. Perhaps you didn’t find anything worthwhile in the “Processes” tab, then go to the tab "Details", it shows all the running processes and try to find the one that is using the CPU the most. If you don't know what to complete, I recommend contacting an experienced specialist.

Of course, using the task manager it is not always possible to find the required process, then a third-party utility comes to the rescue Process Explorer. Run it and sort the processor by load (CPU) and see what it gives us.

Download Process Explorer: https://technet.microsoft.com/ru-ru/bb896653.aspx

Sometimes, the real culprit of the load may appear, and then you can close it without problems, but there is another situation when it is the system process that is loading the CPU. Often this can be a process of system interrupts and getting rid of this is not always easy. Of course, sometimes a simple reboot helps.

System interruptions can occur for several reasons: viruses, problems with the hard drive and drivers, problems with printers, scanners and any other devices connected to the computer.

Drivers

You can check whether the reason is really in the drivers as follows: boot into safe mode and check the CPU load, if not 100%, then the drivers are definitely playing pranks. You can try to remove the video card driver and check the load; if that fails, then you will have to remove everything altogether. Although this is a rather risky process, which ultimately still involves reinstalling the system.

Problem due to viruses

Viruses are capable of many things, and CPU usage is no exception. They can even hide under the guise of system processors, so the average user will not even understand. Try using several utilities to scan your PC for viruses, I will give several links to such programs and how to use them.

Hard drive problem

In general, this doesn’t happen often, but I’ll also describe this point to be on the safe side. Hard drives have two operating modes - DMA And PIO. The first involves working directly with RAM, while the second is outdated and uses the processor during operation. Naturally, if your hard drive is running in PIO mode, then you need to switch. This article describes how to do this.

Peripheral problem

The easiest way to check if peripherals are the culprit of CPU usage is to disable everything in order. Also, go to the device manager and check if drivers are installed on all devices. If a yellow triangle or a red icon is lit there, then such a problem may have occurred due to the lack of drivers.

You can get to the device manager like this: press the keys Win+R and enter the command there devmgmt.msc .

If you see a lack of drivers on some devices, update them directly from the device manager, or use third-party utilities.

Hardware problems with CPU utilization at 100%

Dealing with hardware problems is a little more difficult than software problems, especially for an inexperienced user. But we will try.

A common cause of load is overheat. What do you think causes it? Most likely due to a poor cooling system or dust.

First, let's check with AIDA64 or any other similar processor utility. In AIDA64, open the tab "Computer" and go to the section "Sensors".

The optimal temperature for your processor can be determined on the manufacturer's official website. On average, of course, up to 40 degrees is normal. From 50 degrees and above already puts one under suspicion, and above 70 degrees indicates some problems. Of course, for some processors even 70 degrees is the optimal temperature.

In this case, it would be wise to check the CPU cooling system first. Open the computer or laptop case and, preferably, clean all components. For cleaning, use a brush and vacuum cleaner. Cleaning often is not necessary, but at least 2 times a year is necessary. We make sure to change the thermal paste on the processor about once every 3 years.

Of course, the described methods do not fully solve the problem with the processor. Hardware problems can even include damage to the processor, which is rare, but the only recommendation in this case is to replace it. This can be problematic on a laptop, since they often cannot be replaced. In general, explore and if you have questions, ask them in the comments.

Svchost.exe (host service) is a file and process of Windows operating systems. Its task is to load and execute internal services from dynamic link libraries (files with the .dll extension), ensuring the functionality of almost all components of the operating system. Figuratively speaking, svchost.exe is the liver, kidneys and lungs of Windows, without which its existence is unthinkable. But why do these “vital organs” sometimes create so many problems for us?

Today we’ll talk about what to do if svchost.exe loads the processor, preventing you from working normally on your computer.

Reasons why the system is loaded by the svchost process

Since svchost.exe handles a significant portion of system services, there can be many reasons for heavy CPU load. Here are the most common ones:

• Viral infection.
• Too much network congestion, for example, with many open slots in uTorrent.
• Errors in device drivers (sound, network, etc.), since the latter closely interact with system services.
• Damage to operating system files (in particular, the service host itself and various dynamic libraries).
• System service errors.
• PC hardware malfunction.

Sometimes this happens as a result of an unsuccessful pirate campaign. Windows activation(not all activators are equally useful) and hacking programs.

How to determine which service is loading the service host

To view the services running in the loading host process, the built-in or alternative task manager is suitable. In the first, the information we are interested in is contained in the section “ ProcessesWindows" Each host process is listed under the name " Service node».

The green frame in the screenshot shows the list of services of one svchost process.

As an alternative to the stock task manager, I prefer the free one from Sysinternals. In it, just hover the cursor over a line - and all the necessary information will be displayed in a pop-up window.

If there is more than one service running in the loading host process, you will have to brute-force to find the one that is causing the problem:

• Open the application " Services"(the open button is located at the bottom of the task manager tab of the same name).

• Disable the first service from the list of loading service host: open its properties through the right-click menu and select from the list " Startup type» « Manually" or " Disabled».

• Reboot your computer. If the problem persists, start this service again and disable the next one.

A problematic service has been detected, what next?

Then act according to the situation. If the failure is caused by a minor component, e.g. Superfetch(quite often creates a problem for Windows 8 and 10 users), just leave it disabled. If the service is related to hardware (audio, network, etc.), try updating or rolling back the device driver. If you have problems with Update CenterWindows(often found on G7s and XP), in 90% of cases disabling the update check helps. However, completely refusing to install system updates is a big security hole in Windows, so it’s better to switch it to manual mode.

If svchost started to load the processor after installation Windows updates, applications or drivers, or uninstall the source of the crash.

In some cases, cleaning the folder helps \Windows\Prefetch, where Prefetcher trace files are stored, a system component that speeds up the loading of the system and programs.

How to unload the network

Too much network congestion, network driver errors, failures of applications using the Internet, network viruses (worms) become the source of the problem, perhaps, in half of the cases. To check this version, disable the network adapter in Device Manager and restart your PC. If the load on the processor has returned to normal, the cause has been found, all that remains is to find the culprit.

The following helps reduce processor load on network components:

• reducing the number of simultaneous downloads and distributions of torrents;
• prohibiting access to the Internet for programs for which this is not necessary (especially if there are many of them);
• shutting down network programs when not in use;
• cleaning temporary folders (temp) – they may contain incompletely downloaded files that downloading applications are trying to download to the end;
• antivirus scanning for network worms;

Another “disease” tormented Windows 7 for quite a long time. With it, the CPU load of the svchost process reached 100% and decreased only when the network was turned off. The reason lay in the uncontrolled “reproduction” of virtual tunnel adapters Microsoft 6to4, of which sometimes several hundred were created.

To check if this is your case, open the device manager, go to the " View" and check the box " Show hidden devices" Next, expand the list of network adapters. All "Microsoft 6to4" clones, if any, are located there.

To resolve the problem, simply delete the extra copies of virtual adapters. This can be done either manually one at a time or automatically – all at once. For automatic removal you will need a console utility, which is available for download on the MSDN Microsoft website.

After unpacking devcon to your hard drive, run the command line as administrator and follow the instructions C:\devcon.exe remove *6to4*(instead of C:\, specify your path to devcon.exe). To prevent this from happening again, update your operating system.

Today, the problem with 6to4 adapters has already been fixed by developers and occurs only in those who do not install Windows updates.

What if it's a virus? How to distinguish a malicious svchost from a normal one

The malware can:

• Create a copy of yourself on your hard drive under the name svchost.exe, which will be located anywhere except in the directory \Windows\System32, since it contains the same name system file. That is, to disguise itself as a system process.
• Inject your dynamic libraries into one of the legitimate host processes.
• Modify (patch) the svchost.exe system file by placing your own executable code in its body.

Some users are afraid of what they consider to be too many running host processes. In fact, this indicator does not mean anything bad. The number of svchost processes in a normally operating system is 8-9 or more. Each of them runs one or more services - this can be seen in the task manager. Services are divided into groups depending on the level of access to resources they need, so there are several processes.

Most normal host processes run on behalf of the system, network service, and local service. Before the release of Windows 8, any host service launched on behalf of the user was automatically recognized as a virus, but now this is only true for Windows 7 and its predecessors. In G8 and 10, one service host working on behalf of the user is the norm.

The fact that the host process is running or being used by a virus is indicated by at least one of the following signs:

• The host process file is NOT in the folder \Windows\System32.
• The process is running an unknown service or has a non-system library (.dll) loaded into it.

• On Windows XP-7 the host process is running on behalf of the user, and on Windows 8-10 there is more than one host process on behalf of the user.
• The Parent process of a normal service host is always the Services.exe application. When infected with a virus, anything can happen instead.

The screenshots show ProcessExplorer, running as administrator. To view the list of .dlls loaded into the service host, select the last one with a mouse click and press Ctrl+D on the keyboard. To find out its parent process, click the " Properties" in the top panel of the program and open the tab " Image».

What to do if svchost.exe is infected with a virus

It is important to figure out where exactly the infection is hiding: in the system file svchost.exe itself or in the one that uses it. If a system file is infected, do not delete it under any circumstances, but replace it with a clean one, taking it from a similar copy of Windows (to do this you will have to boot the computer from another medium). Malicious libraries, on the contrary, must be completely removed.

How to check system files for errors

Most of the dynamic libraries from which the service host loads services are Windows' own files, a smaller part are components of device drivers. The console utility sfc.exe can help fix system file errors.

Run the command line as administrator and follow the instructions sfc/scannow. The /scannow option means: “immediately scan and replace all corrupted files from the cached copy.”

The results will be shown after the test is completed in the same window.

What to do if nothing helps

In quite rare cases, 100% CPU load on svchost.exe cannot be eliminated even by reinstalling Windows. The culprits in such situations are faulty drivers or even the devices themselves - network adapters, audio codecs, RAM(the latter's errors sometimes manifest themselves in very bizarre ways) or something else. There have been cases when the problem was solved by the computer.

If suspicion falls on the hardware, first of all try to completely reinstall all drivers using known stable versions. Check the devices by turning them off one by one - in the BIOS or, if possible, physically. If you find the source of the problem, replace or repair the problem unit.

Working on a personal computer requires quite a lot of effort from the user. But this is only if the main goal is to create a productive device. If your PC is slow, this could be due to a variety of reasons.

One of the most common options is CPU overload. If the user begins to analyze the current situation, he may note that the fault lies with completely incomprehensible applications and running processes.

Strange central process loading is a problem that many users face. This also applies to the most modern processors. Therefore, it is necessary to look for a reason other than outdated equipment.

In some situations, you can reinstall the operating system. Another popular method is to update and install the necessary drivers. This real problem must be dealt with using effective techniques.

Finding out the reasons

The relevance of this issue is very great. Users need to first find out which program is to blame for such a negative situation. This problem is quite common, so many users are interested in it.

To assess the degree of CPU overload, you need to open the task manager. After that, go to the tab with all applications that are running on the personal computer. Next, all objects are sorted according to certain parameters. You can do this by name or by load produced.

The problem can occur even when the user has closed the application, but it is still in the active list. As a result, they load the system. And the user may not even be aware of this, since he is sure that he closed the program or game.

If problems start, you can reboot your personal computer. In some cases, this helps, since in this way the downloaded programs will still be closed. You can also use the task manager. With its help, you can close all the necessary objects even faster.

At the time of processing the result of all displayed processes in the download, the user should conduct an analysis. Some applications may be dangerous. If they are not eliminated in time, users will experience gradual or a sharp decline device performance.

Professional help

A situation may arise when all programs are closed, but the CPU load is quite high. Such situations are also not uncommon. In this matter you cannot do without the help of specialists. It is not at all necessary to take the device to the specialist. You can use the Process Explorer utility.

The application will help you see all hidden downloads. Once the list appears on the screen, you can sort unnecessary services. You should also identify whether there are any suspicious objects in the device. To do this, you need to use this particular software product, since the Task Manager is not always able to display all the elements.

Active struggle

Most common cause The problem that arises is the lack of necessary drivers. Users need to boot the device using safe mode. Immediately after this, you can assess whether there is a load on the processor or whether there is no such problem.

In most cases, the reason lies precisely in the drivers. The most the right way is to reinstall the OS. It is better to entrust such actions to a specialist. Only after installing the system should you carefully download drivers. These components must be installed one at a time.

Users need to act very carefully. It is better to download directly from the official website of the manufacturer of your device. In this case, the risk of problems occurring is reduced to zero.

In second place are viruses. It is these pests that can negatively affect the operation of the processor. Some of these objects can extract files. Also, pests simply steal personal data and other important components. The appearance of banners is also the influence of malware.

Fixing the problem is a very simple process. All you need to do is install a high-quality antivirus service. First of all, it will begin the process of scanning the system. An effective utility can identify all pests different types and types. Afterwards, you can eliminate all threats and begin to eliminate problems that arose due to viruses.

The performance of the device may also decrease if HDD mode is activated. It is important to ensure that the hard drive operates exclusively in DMA mode. Any other option will lead to all sorts of problems and failures.

You can also check the impact of all connected objects. To do this, simply disconnect the mouse, flash drive, if it is a laptop. If the work is carried out with a desktop computer, then the user must also turn off the monitor and keyboard.

You should pay attention to the Device Manager. If yellow or red icons are displayed next to some devices, this may mean that the drivers are not working correctly or are missing. So users need to mandatory study all the displayed information.

Based on this, conclusions can be drawn about the state of each element. So you can immediately download missing drivers or update outdated versions. If necessary, users can entrust some problems to real experts, who will certainly help solve all problems professionally.

Another common reason is the presence of dust and dirt. Some users do not keep their device clean. Therefore, the result of such negligence is overheating of the device. The cooler starts working much faster just to cool the personal computer.

Also replacing the differential in the operating mode. The device can work either stronger or weaker. Also, the spontaneous reboot and shutdown of the PC is no exception. Users can fix all these failures themselves.

It is important to constantly monitor the temperature of the device. To do this you should special utility. The application will be able to estimate the optimal performance indicator. When it increases to a critical level, a notification will be shown. So the user needs to immediately identify the cause and try to eliminate it as soon as possible.

Dust cleaning must be done at least twice a year. Each user can do this independently. The thermal paste should also be replaced during the cleaning process. This is a fairly simple process. You should first read or watch a video on this topic.

Each considered problem-solving option is really effective. Users only need to find out the reason to choose the right method. If it is difficult to decide to implement any process, then you can simply reinstall the operating system. It's a win-win.
