Damage Caused

Overheating affects the efficiency and performance of your laptop. As we know, laptops are electronic products. They produce lots of heat when in a working state; for this, there are small ventilation spaces present which allows the heat to leave the laptop space. The clogged vents could cause your laptop to crash or freeze, depending on the severity.


First of all, open up your laptop and clean its interior. Secondly, check your laptop’s ventilation space, inhalation vents, and exhaust vents, and clean them properly. After cleaning them, put a piece of filtered cloth over the inhalation vent. It will prevent the dust from building up again in the future.

2: Hard Drive Diagnosis

Sometimes, your hard drive becomes slow due to excessive data files. The disorganized data on your drive becomes difficult to obtain because they are going through poor fragmentation and bad sectors. This makes the overall performance of your hard drive slow.
