I left the room, came back and PC was off. I thought it was the power supply, so I swapped it, no good. I had my old motherboard, cpu, ram, swapped all thinking it was the mother board, still no go. Tried unplugging the extra storage devices(an additional ssd and hdd, each), shorting out the power switch posts, new power cord, no post beeps, tried flipping the power switch cable from case to header on the header because maybe I had the positive and negative posts wrong, nothing. All fans power up and power off, power up, power off continuously. Any suggestions? Bad case maybe? Everything I swapped was in working order previously and just put in storage as spare. I checked and rechecked PSU cables were in the right spots and nothing was missing plugs.
