So today when I tried turning on my PC, it wouldn't start. I've started unplugging peripherals 1 by 1. No success. Took out the gpu out of the system, and it would now start but turn off after 1 second. So I've tried taking out 1 stick of ram and it turned out 1 stick was faulty. No big deal, I can live without 1 stick. So I've tried plugging my gpu back in and the computer fans would just turn on, but there'd be no video and no beep (the pc beeps once when I turn it on). So I've unplugged the gpu, and surprise, the PC works fine without it. Do I have a dead GPU?
