Why does my ASUS laptop turn off by itself?

Why PC turns off by itself
Have you ever had your laptop suddenly turn off and turn back on for no particular reason? This can be very troublesome especially if you have not yet saved your work. Is there anything more annoying than losing your work this way?

In this article, we will identify the causes of these unwanted "reboots" and show you why your PC is shutting down on its own. We will also provide you with some solutions!



The PC crashes: Is your computer is properly ventilated?


One of the reasons that can cause your laptop to shut down and restart is the extremely high temperature exerted on the components is not being dissipated. This may be due to a problem with the fan or with a buildup of dust inside the PC.

To test the fan, you can position your ear close to the chassis and listen to see if the fan is spinning smoothly and not making unusual noises. You can, also, download software such as Everest or Speedfan that will provide you with information about the fan's rotation speeds and different internal temperatures.


Speedfan - Everest

If the temperature exceeds 100 ° C, the thermal protection of your laptop PC activates and turns off your computer for safety. In this case, you can use a compressed air canister to blow the dust out through the ventilation slots.

If this does not work, you will certainly need to change the thermal paste and/or the fan itself. This task is recommended for those who have some experience in PC repair.
