So a few days ago my PC shut off while in use and won't turn back on. First i did the paper clip test on the PSU. It all worked until i tried to plug the PSU into the CPU1 slot. I then put the 24-Pin connector back in the motherboard. once again it would only start up with the PSU cable unplugged from the CPU1 slot. This leads me to believe that the issue is with my CPU, but i'm worried it may also be my motherboard. Please respond with help as soon as possible, as i would like to fix this by the end of the week.
