I have read quite a few of these but there never seems to be an answer. i just got the system in my sig in today, got it all put together running great. i was installing software on my computer and went to a random restart. when it goes to boot back up it comes on for about 3 seconds then shuts back off. i have tried to reseat the cpu, clear cmos, all power connectors r hooked up. does anyone know something im missing here? i really want to get to gaming!

You likely have a short. Try unplugging everything except the CPU,1 DIMM RAM and the video card and boot the system with only CPU, RAM and video card and get to BIOS. The HD, optical drives, sound cards, etc., unplug it all. If the system still won't post, your MB may be shorting out the system. It likely a short OR a bad PSU.
Well, you might try taking the MB out of the case and trying to get it post with CPU, 1 DIMM RAM and the video card. Your description sounds to me like a short. If you set the CPU voltage too high in BIOS, resetting the CMOS jumper should reset that voltage to default too. It's pretty hard to burn up a CPU...unless you shorted it out somehow.
To find a short. Unplug EVERYTHING except the CPU + fan, 1 DIMM of RAM in slot 1 and video card. Boot and see if BIOS comes up. IF not, you would have to take the MB out of the case and set it on a cardboard box and try again with ONLY the CPU, RAM and video card. The system only need the CPU, RAM and video card to post BIOS.
