CPU utilization is 100 percent. What to do, the reasons and the correction

One of the most common and obscureproblems is the CPU load. 100 percent of his work selects incomprehensible processes and services, which makes the use of computers extremely difficult. Why is this happening?

CPU utilization is 100 percent. What to do?

Quite often, computer owners canTo observe deterioration in work, delay in reaction to user actions and other problems after some time of continuous use. One of the most common reasons that can lead to this is full CPU usage by incomprehensible running processes. The simplest advice is to restart the computer. In some cases, it can help. You can advise to reinstall the system, but this is the most extreme method, which already enters into the category of anecdotal recommendations in most technical forums.

The most common reasons for increasing the load on the processor

Those who are worried about this issue are quite numerous. And they are all looking for an effective solution to their problem without using cardinal methods. And for this it is necessary to understand the reason that could lead to such a situation. If you turn to forums where questions related to this behavior of the computer are found quite often, you can highlight the most common situations:

• Run a program or process that uses increased computer resources.
• Violations in the operation of the system.
• Overheating of the processor due to accumulated dust and insufficient cooling.

Identification of problems and their solution

In order to determine why the CPU 100 loada number of diagnostic procedures will be required. After the reason is established or there is reason to choose one or the other, it will be necessary to take the actions necessary to eliminate it. Details of what needs to be done in each case are discussed below.

The definition of a program that loads the processor

The first thing to do when the computer becameslow down and react poorly to mouse commands and other actions - this opens the task manager. To do this, you can simultaneously hold down the combination of the keys Ctrl, Alt and Del or Ctrl, Shift and Esc, or call the context menu in the taskbar area and find the appropriate item in it.

In the window that opens, select the detailedrepresentation, so that tabs appear, among which there will be needed to us - "Processes". In it, you can see when the CPU loads 100 percent. What to do next in this case?

A full list of allprocesses that are currently running on the system. By default, they are sorted in alphabetical order, but you can select a column with the CPU load to determine the one that caused the problems.

Quite often it happens that the massiveA program that requires large resources costs is not unloaded correctly after the shutdown. As a result, processes remain in the work, and the processor load continues. At the same time, just click on the "Delete task" button to solve the problem. In this regard, it may be effective to reboot the system, which was recommended at the very beginning. Roughly speaking, during it there is the same removal of tasks. In addition, additional resources are released, which can be overlooked independently.

In the process list,unknown, which was not before. And they can also take part in the boot of the system. This behavior is typical of viruses, so it would be good to know the names and characteristics of processes that constantly work in a particular system, and periodically check the list of those running for suspicious activity.

System malfunctions

The first method does not always make it possible to determineThe reason for the CPU utilization is 100 percent. What to do in this case? In practice, in the task manager, it may turn out that the entire load falls on the point "Inactivity of the system". And in this situation, it will not be possible to remove the task.

The recommendation in this case will be to launchutility, which is distributed by Microsoft for free. Process Explorer provides an expanded picture of what the Task Manager shows. In this situation, CPU utilization of 100 percent can be due to system interrupts, which in this program are referred to as Interrupts. It is difficult to say exactly what is the reason for this behavior, if you do not take additional actions.

What can the processor load in the system

Often such a problem is incorrectly citedwritten drivers. To detect this will help to boot the system using safe mode. If the CPU does not experience the same load, then with a high degree of probability, the reason is in the drivers. We need to look for their new versions, provided directly by the manufacturer of the computer or laptop.

Also, this behavior of the system can result in various viruses that have settled in it. In this case, you need to start scanning the system with antivirus software.

As a result, problems with connected devicesAlso, CPU utilization may be 100 percent. What to do with this? The advice is quite simple. It is enough to disconnect everything from the computer, leaving only the most necessary minimum set of mouse, keyboard and monitor. Also, you should look into Device Manager to check for possible problems there.

If these tips do not help to solve the problem, thenyou will need to reinstall the system. It's good if in the process of work points are created that can be recovered, if the system at that time was working properly.

The accumulation of dust and overheating

It is often possible to determine why the CPU 100 loadpercent reaches, helps the cooler's work and the CPU temperature rise. Typically, this indicates that the computer or laptop has long been time to clean off the accumulated dust and dirt in it, and replace the thermal paste. The same leads to braking and system failures. It is recommended to clean it at least once a year.
