Hmm, I've had my Rampage IV Extreme + Intel i7-3960X running for about a month now without any problems but today I got home to a "system_service_exception" BSOD and now it doesn't seem to post any more.. It get no picture on my monitors, the fans run at full speed for 2-3 seconds and then turns down like they should considering my BIOS settings but there is no POST sound and nothing happens at the debug LCD on the motherboard just shows "01".

I suspect either the motherboard or my GTX 580 to be faulty, but do you know what "01" on the LCD is supposed to tell me?
