So recently (within the past month or two), my PC has been having some troubles. It keeps restarting when playing games like Insurgency or Dying light or even some VR games that I had no problem playing earlier. Now, however, the PC restarts and pretends like nothing ever happened. But oddly enough, the time it takes to restart is significantly lengthened when I remove the side panel. I know for a fact that the temps don't have anything to do with this (under load my CPU is at 50-60 degrees and my GPU is always under 60). Any help would be greatly appreciated.
