PC help needed, sudden loss of display, and audio.

I was playing schedule 1 when I suddenly lost display and sound from my computer, the computer still had fans spinning, and lights on. I've been able to recreate this in multiple games, I have deduced that it's not a heating issue. And I've tried reinstalling cpu and gpu driver, I did a system restore to a few days ago and the issue still continues. I'm just looking for ideas to try because I've never encountered this before
