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.
