Hello,

Recently I've come across some issues with my PC just shutting off while gaming with no blue screen or anything, as if i had just held the power button down. This problem has only been occurring recently, as I was able to play the games that cause it to shut down before without any issues (games like Arma 2 and Sims 4) but I can run other games like Stellaris and Rocket League, for example, just fine. I've had the PC for around 4 years without much upgrade so it is a bit outdated. I've also looked through some of the other threads with the same problem, but I can't seem to figure out exactly what's wrong with mine.

Here are my specs:

Yea it is a test. In device manager under processor disable all the cores and run your game. If it works fine enable one by one and see when it breaks. If it runs well the it could be temperature, heatsink needs cleaning.

Which ones would I disable? And is it just to test if any of them aren't functioning correctly? Never done this before. Also it looks like the disable option is grayed out in the device manager.

It could be the cpu overheating. Download a program called speedfan and then see what the temps are halfway through your game. If they are above 80c then you need to check the thermal paste
