What to do if the CPU usage is 100
When we use the computer, sometimes we will encounter a situation where the CPU usage reaches 100%. CPU usage refers to the load level of the computer's processor performing tasks. When the CPU usage reaches 100%, it means that the CPU reaches the limit of its processing power when performing tasks, which may cause the computer to run slower, or even freeze and crash. Here are some ways to deal with and resolve 100% CPU usage.
- End the process that is occupying the CPU: First, we can use the task manager to see which process is occupying a large amount of CPU resources. Press the Ctrl Shift Esc key combination to quickly open the Task Manager. In the "Processes" tab, we can sort the processes in descending order of CPU usage and find the process that takes up the most CPU resources. Right-click the process and select "End Task" to terminate the process. However, you need to be careful not to terminate system processes to avoid causing system instability.
- Close unnecessary programs and windows: In the Task Manager, we can view the number of programs and windows running on the computer. Closing some unnecessary programs and windows can reduce the load on the CPU. For example, close some applications, games, or browser tabs running in the background.
- Clean and optimize the system: Long-term computer use will cause fragmentation of system files and registry, which may affect CPU performance. Regular hard drive defragmentation and system optimization can improve the overall performance of the computer and reduce the load on the CPU.
- Update and upgrade drivers: Outdated or incompatible drivers may cause high CPU usage. Therefore, we can check and update the computer's drivers, especially the graphics card and sound card drivers, to ensure their compatibility with the operating system.
- Perform a virus scan: Sometimes, malware or viruses can also cause 100% CPU usage. Therefore, we can run anti-virus software to conduct a comprehensive virus scan to ensure the security of the system.
- Increase memory capacity: If your computer is low on memory, the CPU may be forced to take on more work, resulting in high CPU usage. In this case, you can consider increasing the computer's memory capacity to improve system performance.
- Consider upgrading the CPU: If the computer's CPU performance cannot keep up with the current task requirements, and the CPU usage remains high even after taking the above measures, then considering upgrading the CPU is a longer-term solution.
100% CPU usage may be a symptom of computer system performance or configuration problems, or it may be attacked by a virus or malware. Through the above methods, we can solve most of the problems with 100% CPU usage. However, if the above methods still do not solve the problem, it is recommended to consult a professional computer technician for further support and advice.

In MySQL, add fields using ALTERTABLEtable_nameADDCOLUMNnew_columnVARCHAR(255)AFTERexisting_column, delete fields using ALTERTABLEtable_nameDROPCOLUMNcolumn_to_drop. When adding fields, you need to specify a location to optimize query performance and data structure; before deleting fields, you need to confirm that the operation is irreversible; modifying table structure using online DDL, backup data, test environment, and low-load time periods is performance optimization and best practice.
