Not entirely sure whats wrong. thought possibly it was a game causing it to constantly crash, although it happened while I was just watching Netflix too.

Basically, at random times the screen will completely go black, and then turn off as if the computer was turned off, however, I'll still be able to hear in-game sounds, and anyone on discord and the computer will stay on.

I tried to take out, and put the HDMI cable back in but it didn't work. Updated all drivers, windows updates and all of that. Still does the same thing. I thought it might be a GPU overheating but temperatures are at 30 idle with full fans on, so possibly a PSU supply surge? Not sure what else to try.

Anyone got any suggestions?
