Computer keeps restarting due to overheating of the case

Reason

Because the heat sink is no longer working well. The computer has a self-protection mechanism. When it gets too hot, it automatically turns off to avoid danger. To recognize this sign, you just need to touch the bottom of the computer. You will recognize it immediately, because you can feel it with your hand. This happens because: the computer has been used for a long time and is covered with dust. Gradually, it makes the computer's ventilation and heat sink work less effectively.

This is one of the most dangerous causes that can damage computer hardware and cause problems for your chip.

How to fix

- Disassemble the machine to check and clean the fan.

- Apply more thermal paste to the chip. If you are not familiar with this, you should bring your laptop to the store to clean the machine and apply thermal paste.

- Invest in a mini fan to keep your computer case cool.

- Placing the computer in a cool place will help reduce the temperature and increase the lifespan of important components in the computer.
