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.

Run an ePSA diagnostic and an AlienAutopsy gaming test to check for hardware errors.
Make sure you have the latest BIOS A12 for Windows 7 and Windows 8 or A13 for Windows 8.1, and try a clean installation of the video driver as explained here.
