Memory overclocking or unstable. There are mainly random blue screens. Returning to normal frequency operation, or finding a good memory stick to replace, can generally solve the problem. You should also pay attention to the heat dissipation problem close to the CPU memory stick; the blue screen caused by poor hardware compatibility.

Solve virus and system problems. Reinstalling the system can solve some problems caused by viruses, as well as various unexpled system problems.

Solving virus problems can solve some problems caused by viruses, as well as all kinds of system problems that do not know the cause and cannot be solved by reinstalling them directly.Avoid the trouble of debris.
