My PC recently died. Randomly, It would lock up, just completely freeze and the audio would get stuck in a loop, sometimes a 5 second loop or sometimes just a rapid buzz. I'd flip the switch on the PSU and let it sit for an hour or so, and it started up just fine. Then one day after work I turned it on and I got no output to either of my screens. Tried using the motherboard HDMI and still didn't get anything. I tried swapping the GPU from my old PC in and still got nothing. The PSU definitely works, everything powers up and lights up like it should. I've reseated my RAM and swapped in RAM from my old PC and still had no effect. At this point, I would say I've got a bad processor or motherboard. Is there any way to test them to see what may be the problem before I drop the money on a new processor or motherboard?
