I was playing a game and then all of a sudden i got a black screen and the computer froze, after i restarted the computer i just had the same problem over and over. nothing shows up but a black screen. however i also noticed that the lights on my keyboard and mouse don't light up either but the fans all work.
but when i unplug the GPU from the psu all the lights turn on and of course the fans work as well.
i'm almost certain that this is hardware failure since i have tried everything except replacing a computer part.
but my question is, is the psu broken or the gpu? i honestly have no idea and can't afford to just buy a part without being certain. (i don't have a spare psu/gpu to test out)
