I was testing an overclock at 4.5ghz with my 3930k using prime 95 when the computer just suddenly turned off now it won't boot at all. I reseated the video card memory and cpu with the same problem. This is with the Asus Rampage IV Formula X79. The onboard led Will light on the mobo indicating it's getting power but when I hit the power button I hear a click and no boot. The only way it will go through the Boot Sequence is if I unplug the ATX 12 Volt 8 pin power cord to the cpu. Think the VRMs on the mobo took a dump?
