Factors causing high CPU usage: 1. The driver has not been certified and a beta driver is installed; 2. The system is infected with viruses, Trojans, or rogue software; 3. Running large programs (such as games) ); 4. Too many startup software programs; 5. Too many disk fragments; 6. CPU aging.
Factors causing excessive CPU usage
1. Driver Not certified
Many users who don’t know much about computers, when installing drivers for their computers, especially graphics card drivers, do not install official drivers, but install beta drivers. 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 the computer software is installed or uninstalled. When the files are installed and uninstalled, the hard disk will be damaged. The data arrangement is very scattered or intermittent, which slows down the computer when searching, resulting in heavy use of the CPU.
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.
6. 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.
