I started experiencing this issue recently. Whenever I play a game for an ex Doom 4 on high and 1080p my screen goes black and sound freezes in a loop, however, pc is still running. I tested my RAM, SSD, CPU and video card. Everything is working correctly. Can you advise what tests should I try to do before I return the MB. I tried a different power supply, problem still persists...
Here are the specs:
