My Pc is dying

Hi! Not very good news-my pc is dying.I had this issue for months now,but still was able to launch VAM with 50-50% chance.Now I literally can't launch anything harder than web browser. On any perfomance heavy app or game my pc just shutting down. And it won't start after that,I need to literally disable power for like 10 seconds and turn power again for pc to be able to start.Honestly it was insanely lucky that I managed to finish midget scene.

I hope this is just power supply issue and not something more complicated. Waiting for another power supply now,should take couple days.

So I guess I will chill till the end of this week probably,can't do anything anyways.Will do some fishing for whole days.
