You are troubleshooting a computer that your client said turns off during normal operation. While you are trying to identify the problem, the client also informs you that if he waits a while, the computer will turn back on and run normally for a bit. You open the system and immediately notice a large dust buildup around the processor fan and heat sink. What problem can you detect on the computer and confidently report to your client?

In this case, it seems to me as the system is overheating.

Explanation:

The reason why this is the case is because the processor (CPU) needs airflow to constantly cool itself when running tasks. The airflow works by intakes and exhaust fans within the computer case. Specifically around the processor fan and the heat sink, it is usually designed for exhaust (Some can also be intakes as well). The dust that is collected restricts the fan from properly exhaust all the hot air from the CPU as the dust can be clumped up together. Both the heat sink and the fan are the main components as the air flows through those areas.

Your computer doesn't necessarily just let it burn itself out. It is constantly monitoring the temperatures of the system and if it reaches a limit, it will turn off the system to prevent it from overheating and will turn back on when the temperatures are acceptable to run again.

Have a nice day!
