Now I am dedicating it to netizens for their reference.
First of all, it seems that the computer is silent, but sometimes the problem is more complicated, involving both hardware and software issues. Therefore, we must first find out the cause, whether it is software or hardware failure, and then prescribe the right medicine for the problem. You must not mess around without knowing the cause.
