What is the reason for high cpu usage?

When we use the computer, when the CPU usage of the computer is too high, we will feel that the computer becomes very laggy. There will be no response when operating the computer for a long time. In severe cases, it will crash directly. So what are the reasons that cause the CPU usage to be too high? The following article will take you through it, I hope it will be helpful to you.

#There are many reasons for excessive computer CPU usage. Some are caused by software and some are caused by the hardware itself. The following will give you an analysis of several reasons for high CPU usage:

1. The driver is not certified

Many users who do not know much about computers, When installing drivers for the computer, especially the graphics card driver, the official driver is not installed, but the beta driver is installed. Many test version drivers are not standardized and occupy a lot of CPU resources when the system is running.

2. Viruses, Trojans, and rogue software

If the system is infected with viruses and Trojans, they will continue to run and replicate in the background of the computer, causing them to occupy CPU resources. The computer system is experiencing severe lag.

However, rogue software is software that is between viruses and regular software. If there is rogue software in the computer, it will run automatically without the user's permission, occupy CPU resources, etc.

At this time, you need to use anti-virus and powerful uninstall software to uninstall anti-virus and software.

3. Run large programs (such as games)

Sometimes the high CPU running rate is caused by some large programs, such as large games that occupy a lot of CPU. There are two normal reasons. The first is that the written program does not meet the requirements, causing the CPU running rate to be very high.

4. Too many software programs are started

Many friends like to start multiple software at the same time, such as opening dozens of browser windows at once. You should know that every time you open a browser window, it will occupy some CPU resources.

5. Too many disk fragments

Sometimes when the computer software is installed or uninstalled, when the files are being installed and When uninstalling, the data arrangement in the hard disk will be very scattered or intermittent, which will slow down the computer when searching, causing a lot of CPU usage.

So you should always clean up the system garbage, and defragment the disk after cleaning. 6. System service items are not optimized

There are many redundant services in the default settings of the computer system that will occupy CPU resources for a long time and need to be optimized.

7. CPU aging

In fact, computer system software is constantly being upgraded, and WIN has gone from 32-bit to 64-bit. This results in higher and higher demands on the CPU. If you use a single-core Celeron-level CPU to run WIN7, the CPU basically cannot support it.

At this time, the CPU needs to be replaced.
