Hello, I've owned this PC for 18 months now, and a new issue appeared yesterday evening. I was playing CS:GO when my PC screen suddenly went black, and the only way to get my PC to work again was through restarting through the power button. Now I have cleaned the dust and re-applied thermal paste, I'm not sure what to do here.
