I was playing a game when my computer froze up. I shut it down, and tried to reboot. Nothing comes up on screen, and no power is even getting to my mouse or keyboard. All fans/lights turn on. I have an ASRock Z68 Extreme3 Gen3 motherboard and it's giving me an status code "04". I can't seem to find any information on this other than the manual saying "South Bridge initialization before microcode loading". Did my PSU just take a dump, or what's going on here?
