For solving this problem, I will conduct the following steps:

• To open the cabinet;

• To remove the CPU fan from the motherboard, but don't remove the processor;

• I will take it into consideration that the heat sink is filled with dust that creates obstruction on the free flow of air as a result of which the CPU can not get cool;

• To clean up heat sink and the fan, and ins again. Now, after closing the cabinet, I w turn on the computer again.

•  If the problem is not yet solved, I will take t computer to a service centre, and talk to experienced mechanic.
