What to do if the CPU usage is 100? Why?

In recent years, with the rapid development of science and technology, computer technology has become an important part of modern society. Whether for personal use or corporate work, computers play an important role. However, when using the computer, we sometimes encounter situations where the CPU usage soars to 100%, which brings great trouble to our work and study. So, what is the reason for 100% CPU usage? How should we deal with it?

First, let’s take a look at the causes of 100% CPU usage. There are several situations that may cause the CPU usage to reach 100%:

1. Virus or malware infection: An infection with a computer virus or malware may cause the CPU usage to skyrocket. When these software are running, they will continue to occupy CPU resources and increase their load.
2. Software or process anomalies: Some software or processes may be abnormal, causing them to occupy CPU resources abnormally. This may be due to bad design of the software, an outdated version, or driver issues.
3. Resource competition: When multiple programs compete for computer resources at the same time, the CPU will be occupied by multiple programs, causing the CPU usage to reach 100%.

When we find that the CPU usage reaches 100%, we should take the following measures:

1. Kill the abnormal process: Open the task manager and look for the CPU usage. high processes, try to end them. If there is a virus or malware infection, you can run anti-virus software to scan and clean it.
2. Update or uninstall software: If we find that a certain software or process causes CPU usage to spike, we can try to update the software or uninstall them and find replacement software.
3. Close unnecessary programs: Close unnecessary programs or processes running in the background to release CPU resources.
4. Check hardware devices: Sometimes increased CPU usage may be caused by hardware failure. Check whether the hardware devices are working properly, such as whether the radiator is blocked, whether the fan is running normally, etc.
5. Upgrade hardware: If you encounter problems with high CPU usage for a long time, it may be because your computer configuration is low. Consider upgrading hardware, such as replacing a faster CPU, increasing memory, etc.

In short, CPU usage reaching 100% may be caused by virus or malware infection, software or process anomalies, resource competition and other factors. We can deal with this problem by killing abnormal processes, updating or uninstalling software, closing unnecessary programs, checking hardware devices, and upgrading hardware. At the same time, regular system maintenance and security checks can also help us reduce excessive CPU usage. Keeping your computer in good running condition is crucial to our work and study.
