Exactly as the title says. I was playing games with my friends and then suddenly it shut off, and i was left with a pc that wouldnt turn on. I took out the psu, unplugged it from the mobo, did the paperclip test, and it turned on with no problem, plugged the cables back into the motherboard, and it booted fine. But once i tried plugging in my gpu, it would refuse to even turn on. Any suggestions would be helpful!
