Why the central processor is loaded at 100. Why is the processor loaded and how to reduce CPU loading? Huge number of running processes

If, turning on the computer or working in Windows for some time, you suddenly see that the speed of work has decreased noticeably or the computer completely stopped responding, then the reason for this can be a computer hang - i.e. When it is busy execution of files and does not respond to requests from other computer or programs. What should I do in this case how to correct the situation?

Basically, the loading of the CPU 100 percent in Windows is associated with the activities of malicious programs or errors in the software. Below will look at several common simple techniques to do to eliminate this fault.

To begin with, just restart the computer. Sometimes it happens that some application hangs due to problems in the application itself and continues to use the processor, often at 100 percent. You can delete it through the "Task Manager" - "Remove the task".

Just do not forget to set the "Display all user processes" or "Read more" - to display a full list of processes. After you remove the task - reboot - check the download problem or not.

If the computer reboots did not solve the problem proceed to step windows checks For malicious programs. Run the complete antivirus scan installed with you. You must understand that the presence of antivirus does not exclude the possibility of infection of the computer. Optimally for checking use anti-virus scanners of well-known developers. They are free, do not require installation, they can be recorded on a USB flash drive or a CD and, booting with them, to start checking the PC - this will increase the chances of travelers of majority of malicious programs.

Perform the Windows operating system if you watch the high percentage of CPU loading

Using special software, analyze why one or another process starts and the loading of the CPU increases to 100%. For example, "ANVIR TASK MANAGER" is well suited for this. It allows you to estimate the level of risk and change the type of application startup in the autoload, process or service (the menu shown in the figure is called right-click) i.e. You can understand what to do with it is the cause of the problem.

Thus, prohibiting the launch of applications with high levels Risk You with a large share of probability get rid of processes that ship your CPU by 100 percent.

One of the most common and low-touch problems is the loading of the CPU. 100 percent of its work is taken by incomprehensible processes and services, which makes the use of a computer extremely difficult. Why is this happening?

Loading CPU 100 percent. What to do?

Quite often computers can observe deterioration, delay in the user's response and other problems after some time continuous use. The most common causes that can lead to this include full loading of the processor with low-touch processes. The easiest advice is to restart the computer. In some cases, he can help. It can be advised to reinstall the system, but this is the most extreme method that is already in the category of jecdotic recommendations on most technical forums.

The most common causes of improving the processor load

Those who are worried about this question, quite a lot. And they all seek an effective solution to their problem without using cardinal methods. And for this it is necessary to deal with the reason that could lead to such a situation. If you contact forums on which questions related to such a computer behavior are quite common, you can allocate the most common situations:

Starting a program or process that use enhanced computer resources.
Violations in the system.
Due to the accumulated dust and insufficient cooling.

Identification of problems and their decision

In order to determine why interest, it will be necessary to hold a number of diagnostic procedures. After the reason is established or there is a basis to stop its choice on something one, you will need to make the actions necessary to eliminate it. In detail about what to do in each case is considered further.

Definition of a program that loads the processor

The first thing to be done when the computer began to slow down and react badly to the mouse commands and other actions, it is to open the task manager. To do this, you can simultaneously hold the combination of the Ctrl, Alt and Del or Ctrl, SHIFT and ESC keys or call the context menu in the taskbar area and find the corresponding point in it.

In the window that opens, you must select a detailed view so that tabs appear, among which we need - "processes". It can be seen when the CPU is 100 percent. What to do next in that case?

The tab will display full list all processes that are running on this moment in system. By default, they are sorted in alphabetical order, but you can choose a column with the CPU load to determine the one that caused the problem.

Quite often, it happens that a massive program that requires large resource costs is not unloaded correctly after closing. As a result, processes remain in the work, and the processor load continues. At the same time, it is enough to click on the "Remove Task" button to solve the problem. In this regard, it may be an effective reboot of the system, which was recommended at the very beginning. Roughly speaking, during her there is the same removal of tasks. In addition, additional resources are exempt, which can not be noticed on their own.

The list of processes may also be unknown, which were not before. Moreover, they can also take part in the system loading. This behavior is characteristic of viruses, so it would be good to know the names and characteristics of the processes that constantly work in specific system, and periodically check the list of suspicious activity running for the appearance.

Systems in the system

The first method does not always allow to determine the reason for which the CPU is loaded 100 percent. What to do in this case? In practice, it may turn out that all the load falls on the "idle system" item. And in this situation, it will not work out the task.

The recommendation in this case will start the utility that Microsoft Corporation is distributed completely free. Represents an extended picture that shows the task manager. In the situation under consideration, the loading of a 100 percent processor can be due to system interrupts, which in this program are designated as interrupts. It is difficult to say what exactly the cause of such behavior, if you do not take additional actions.

What can ship the processor in the system

Often, such a problem is incorrectly written drivers. To identify this will help loading the system using safe mode. If the CPU is not experiencing the same load, then with a high probability caused exactly in the drivers. You need to search for their new versions provided directly to the manufacturer of a computer or laptop.

Also on such behavior of the system can cause various viruses that settled in it. In this case, you need to run the system scanning anti-virus software.

As a result of problems with connected devices, the CPU is also loaded 100 percent. What to do with this? The advice is quite simple. It is enough to disable everything from the computer, leaving only the most necessary minimum set of mouse, keyboard and monitor. You should also look in to check availability. possible troubleshooting there.

If these tips do not help solve the problem, you will have to reinstall the system. Well, if the process of rollback is created in the process of work, which can be recovered if the system has worked properly at that time.

Casting dust and overheating

Often, determine why the loading of the CPU 100 percent reaches, helps the loud operation of the cooler and an increase in the processor temperature. As a rule, this suggests that a computer or a laptop has long time to clean the dust, dirt, and replace the thermal paste. The same leads to braking and failures in the operation of the system. It is recommended to clean at least once a year.

Quite often, situations occur when users, noticing that their computers are gently saying, open the task manager and see an interesting picture there. The processor is loaded by 100%, although no "heavy" applications are not running. Full loading of the processor is unknown than and causes braking and hanging PCs.

In this article we will give several delight tips on solving this problem.

The reasons for which the processor can be loaded by 100%

Now we will list the most likely reasons for the practically complete workload of the processor when working programs or games are missing at first glance.

Work background system software installation and download updates operating system, as well as its service;
Viral activity;
Physical outdated processor.

Now about each in more detail.

Work background system processes

Operational windows system 7, like any other periodically updated. This process In most cases, the service is covered by the user and is responsible for it.

svchost Surgious processor

Periodic OS checks are not excluded for threats to embedded protection tools.

In fact, it does not matter which system service loads the processor. Another thing is important. What usually lasts no more than a pair of hours. Therefore, the first thing for the discovery of increased activity and loading the processor the first thing is to simply leave the computer for a few hours to give it the opportunity to make all its "serving business."

Viral Activity and Viruses - Miners

The second very common reason for which the computer without visible programs loads your processor 100% incomprehensible than it malicious programs. So, for example, the so-called virus is now very popular - Mainer. It hits the computer most often when downloading and installing something from the Internet. And the essence of his work is simple - when you hit the computer, special mining algorithms on your computer bitcoins and sending results via the Internet to a specific address are launched. Thus, on your computer, attackers earn, thereby leaving you with a hoping computer, as its processor is 100% loaded. At the same time, they are masked under the names of system processes!

Therefore, if after a few hours of downtime, your computer has not reduced the degree of processor load, we advise you, and it is better than several different updated antiviruses.

Computer and processor obsolescence in particular

There is also a situation in which the computer is simply outdated and its processor is simply not coping with the background system tasks For maintenance and protection of the operating system. But this is possible only on truly old processors of 10 and more years ago with 1 core.

Output

As you can see possible options not so much. And the method of eliminating the problem with the loading of the CPU 100 percent is as follows:

Check the processor so that it is not too old;
We leave the computer for several hours on and connected to the Internet;
Check it for viruses;
You can also open the task manager, sort the processes by load on the processor and read about the process that the Internet processor is most of all;
In the most extreme case, if nothing helps - reinstall Windows and immediately.

The best way Thank the author to the article - make a repost to my page

The transition to a new OS gives pleasant opportunities, but one of the mass problems is that in Windows 10 hDD It happens 100% loaded. Users are alarming and do not know what to do. Let's figure out with the causes of the occurrence and methods of their elimination.

We are looking for reasons

Pure OS and without viruses, but for some reason, the hard drive is loaded at 100% in the task manager. Let's sort the processes in the column "disk, if this is not the newly installed program, then let's go to look for answers in the Windows processes themselves.

As a result of the execution of the command, the service will be temporarily suspended and, accordingly, the locked process - this can be a solution when loading a disk by 100 percent in Windows 10. But to exclude the repetition, you can disable indexes in the services - if it is not critical for you, it clearly slows down search files and folders. You can turn off when "Control Panel" → "Administration" → "Services" → Find "Windows Search" → First click "Stop" → In the start type, select "disabled" → OK. Text_7 / Screenshot_4 and 5

If the situation has not changed, go further. Perhaps the virus affects the processes and it may be a response to the question "Why is the disc loaded by 100% in Windows 10?" Spend your deep analysis and additionally use the Dr.Webcureit utility - quickly downloads, does not require installation and free.
The next reason may turn out to be antivirus itself. Watch, probably, there is a deep scheduled check of discs, but if this happens constantly, pick up another software to protect your PC.
A fairly common cause is a broken disc, so the operating system toolkit is trying to check and slow down all other processes. Have you ever had a black screen before loading OS? If so, then this check disk (abbreviated CHKDSK) built-in in Windows 10 checks file System your his hard disk For errors, as a result, it is constantly loaded by 100 percent. It is possible to turn off it, but maybe it is worth dealing with the root cause and only then delete it from the task planner.

How else to remove the disc boot by 100% in Windows 10?

You need Drivers! Many many began to install OS independently, but as for the drivers, users consider sufficient installation on sound, video, webcam, etc., and really necessary firewood do not install, apparently do not like file names or they are not clear. This happens with the drivers for the chipset of the motherboard and with ACHI, and Storage Tool. The answer is simple, install them - go to the manufacturer's website and download for free.
Defragmentation will help if the disk is loaded in Windows 10 by 99 percent! For what time you did not optimize your discs? If you can't even remember, forward to! Infinite copying, deleting, loading - lead in full chaos clusters, and when contacting hard file Takes pictures.
Use cloud services Data storage? If so, then probably a tick on "Synchronization". Note what amount of information is merged at this point. If at this moment the disc is loaded at 100 percent, then the answer to the question of what to do is obvious! Disable automatic download and use manual mode - Put at night or when you are not at home.
Another advice on the topic, how to reduce strong load windows disk 10. Torrents are our all! Yes? You not only download, you also distribute, use the program when you are not at a computer and leave at work not 10 downloads, and 2-3 - depending on the configuration of your PC.

What if the hard drive is 100 percent loaded?

Perhaps this load is updated. Again if the screw is not in best conditionThe processor is weak - you can spend hours on it. Let's see how many hidden and unnecessary updates are lung and how to disable them. "Parameters" → "Update and Security" → "Center windows management» → « Extra options»→ Remove the tick with" when windows update Provide updates for other Microsoft products. "

Next, we go to the "Application Store" → Choose your account and "Settings" → We switch to application update to "Off."

Began to notice that when launch Windows 10 Loading your disk 100 percent something busy? The reason may be unwanted files in the autoload - go there: ++ → "More details" (may not be depeted of the settings) → "Startup" carefully examine the contents. TO aK? To remove unwanted applications without harm to the OS, use the software designed for this, for example: "CCleaner", "Autoruns", "Ashampoo Winoptimizer FREE", etc.

On your laptop in Windows 10, the disk loads 100% and you do not know why? The reason can serve the Superfetch service and the SVCHOST system process, the task to optimize the work. Principle Next: Analysis of the most frequently used programs and applications is happening and begins to load in advance system Memoryin order. It takes not enough resources, in connection with which the load occurs. You can disable in "Services" → "Superfetch" → In the properties, select "Stop" → and in the Type of Starting "Disconnection" → OK.

If the disk is loaded at 100% during the System process, it may not be enough rights and need to be added, the relationship with NTOSKRNL rights is the OS core, proven by its action. So, "Task Manager" → "Processes" → Right-click on "System" → "Open the location of the file" → with the right click "ntoskrnl.exe" → "Properties" → Security tab → "Optional" → "All application packages" And you need to put all the checkboxes.

We reviewed different reasonsThrough which your PC is loaded up to 100%. You can read how to find out « » . Perhaps some one tool will help, and it may be necessary to make a set of work on optimization. In any case, do not forget that the system must be maintained in due state. Modern software provides a choice, considering that the majority is in free access and with FREE license.

During the use of the computer there are times when the performance begins to see due to 100% of the processor loading. It is not always possible to solve the problem quickly, since the causes of the problem is a lot and not everyone knows about them. Why the computer processor is 100 percent loaded without visible reasonsWe will understand below.

The first reason to pay attention to is the presence of a program that loads the processor and reduces the performance of the computer. Determine the "pest" as follows:

We launch the "Task Manager";
Run is made by simultaneously pressing the Ctrl + Alt + Del keys or through the Start menu;
After opening the program, select the "Processes" tab. It displays all system processes and programs currently running;
To determine the pest program, sort the processes in the processor load;
Complete the program. To do this, select it with the left mouse button, and then click on the "Remove Task" button;

When closing the program, keep in mind the following nuances:

Stopping an important system process will entail the need to restart the computer manually, since the operating system may hang;
Some applications are left after closing side processes that affect the operation of the processor. This often occurs in case of emergency closure of the browser;

The main reasons for maximum download

The reasons for loading the processor and reduce its performance a lot. Among the main allocate:

Drivers malfunction;
In autoload mode, there are many applications;
The system attack viruses;
The operating system is loaded antiviruses;
Hard disk problems;
Peripheral equipment will cause, which is reflected in the work of the processor;
Simultaneously launched a lot of applications;
Problem in program code;
Applications running in background mode, take away a lot of resources;
The cause of equipment malfunction;

Note! A few reasons can affect the performance of the processor.

Each computer element is running separate programIn which all algorithms for interaction with other devices are laid. Such programs are called drivers and sometimes the reason for the workload of the processor lies in them. To troubleshoot a problem with defective drivers, follow these steps:

Navigate to the official website of the manufacturer and download the new version software for the device;
Reinstall the driver and restart the computer;

Note! New versions of drivers do not always work correctly due to insufficient software optimization. When downloading, pay attention to the "Stable" mark. Its presence means that program code Optimized and when it does not have any conflicts with the system.

Some drivers are difficult to find independently and on developers sites is nothing clear. In this case, use third-party applicationswhich search and install the missing software.

Large number of programs in autoload

Among the modern applications installed on the PC are increasingly found software productswhich after installation start working in autoload mode. It means:

The program automatically starts with the power on;
In autoload mode, the application gets access to the Internet, downloading updates without user notification;

One or two applications do not heat the processor, but 5 - 10 will become a serious problem. The problem is eliminated so:

Simultaneously press Ctrl + Alt + Delete;
We launch the "Task Manager";
Select the "Auto-loading" tab;
Allocate unnecessary programs and click the "Disable" button;

Work on the Internet is accompanied by a risk of picking a virus that loads the processor, interfering with its work. Most often, viruses are masked under system processes, and calculate them even with antivirus program Extremely problematic. In this case, the following action will help:

Restart the system and load Windows 7 in "Safe Mode";
For this, during the reboot, click the F8 key, after which we choose the mode we need;
After activating the operating system, check it for viruses. For this, it is not necessary to download and install a separate antivirus software. On the Internet there are services to make it without installing on a computer. Such a service offers Dr.Web;

Antivirus activity

At work of the central processor (CPU), the work of antivirus can also affect. The fact is that even with a simple system, when the user does not make any actions, antivirus subroutines make their job, the monitor system in search of the enemy. If the computer is weak or the operation of the anti-virus is configured incorrectly, there are failures during operation. You can eliminate them in this way:

Customize the operation of the antivirus, choosing economical mode or shutting down unnecessary elements;
We change the antivirus to less resource-intensive;
We update the computer iron to a new one;

Others effective ways, without risk, damage the OS or antivirus.

The hard drive affects the operation of the processor in two cases:

Winchester fails, because of which the performance of the OS, and in a consequence of the processor;
It is set to install OS updates, which affects the performance of the processor;

The first problem is solved by purchasing new equipment. Yes, it is expensive, but over time the hard disk will completely fail, and you just can not start the computer. The second problem is eliminated like this:

We are waiting for the end of download and installation, after which we continue to engage in our affairs;
Turn off the update autoload;

Other reasons for the processor power drop due to hard disk should not be.

Problems with peripheral equipment

When connecting third-party equipment - mouse, keyboard, printer, or scanner, drivers can not be installed correctly. Because of this, in work peripheral device and the OS arise conflict situations, which leads to the allocation of additional processor resources, to solve the problem.

Actions to eliminate the problem:

In turn, turn off the peripheral equipment and follow the processor response. If, after disconnecting any device, the load is disappeared - reinstall the drivers;
Drivers on the device are installed, but do not work correctly. This is displayed in the Device Manager;

Often, the computer itself signals an incorrect installation of drivers, but you simply do not pay attention to it, continuing to work on "non-relative" programs.

Huge number of running processes

SAMI simple causewhere the processor overload occurs. The fact is that every process, not even visible, takes a certain proportion of strength from the processor, causing to follow his actions. Resources are not limitless and at a certain point the computer will start to slow down, thereby showing overload. Clear the problem is easy - close unnecessary applications. This will unload the processor and the operating system speed will come to normal. Do not need to close all applications. Choose those that are less common at the moment or those that are quick and easily opened when needed.

Important! We work out the habit of not lazy and close unnecessary page on the Internet, applications that are no longer needed. You will notice how the PC speed will increase, and its work stabilizes.

Software problem

To problems software type There is an unstable operation of a particular application. For example, Chrome ships your 100 percent processor. In this case, it will help closing the application, deleting it followed by downloading new version. Often, similar troubles occur due to the installation of non-licensing software in which the program code is damaged.

Such an application is not optimal, taking extra resources from the processor, which during the operation of the license product did not need. If the reinstallation does not help, it means that it is not in the program. Most likely the computer is infected with a virus or hard disk comes in disrepair.

Work background system processes

After turning on the computer or laptop, Windows automatically makes a huge number of system processes, and they do not stop even when the user does not make any active actions. The system.exe is responsible for their work, which is primarily inspected when suspicious.

It is impossible to disable them, since they directly depend on the operation of the OS, whether Windows 7 or Windows 10. Other OS are built by a similar principle. The following things affect the loading of this process:

Service automatic updates Windows;
Work of antivirus programs;
Action of viruses;

Optimization or elimination of these reasons will be returned to your system processes to normal, stabilizing the work of the PC.

Computer and processor obsolescence in particular

As in the case of a hard disk, the processor is not eternal and its working resource is gradually spent. This is due to:

Long life of the equipment;
Inappropriate conditions for the content of technology;
Marriage in manufacturing;
The computer worked in reinforced mode, undergoing constant overloads;

All this can not have a positive effect on the work of technology. It is possible to solve the problem associated with the technical side of the process according to the following algorithm:

Clean system unit, removing all dust and dirt with a vacuum cleaner. Special attention is paid to cooling systems, since the increase in the temperature of the processor overloads it, gradually deriving. Determine the processor is heated or not possible with special applications, in large quantities posted on the Internet. If cleaning did not help and the technique continues to warm up - change the thermal colon covering the upper part of the processor;
Check the operability of the OS, when starting simple applications, such as notebook or Paint. If the "Process Manager" when they start, it shows the processor loading at least 50%, and it does not fall - I recommend paying attention to new models of computers, changing the old iron to the new one;

Step-by-step test of the PC to all the causes listed above will reveal the problem and performance will return to normal. The main thing is not to rush, carefully performing all the stages of troubleshooting.
