PC won't boot, very odd...

Here is the rundown of the recent events:

I built a pc(specs at the bottom), booted it up installed windows 7 x64, installed office, ran all updates, and everything was fine. However I noticed when I rebooted, the screen would go black, however the pc would stay on. It would not reboot or even shut down, however I could shut it down over 30+ times will no issues just couldn't perform a reboot. So I decided to check the bios and make sure everything was set to what it should be and what not. Initially, any time I'd boot to the bios, the main screen would show the clock running however the moment I touched any key the clock would freeze and the cursor wouldn't move. I rebooted a few times and I think I changed the keyboard to a different USB port and the issue was resolved. A couple of time the video acted sort of weird(would appear pixelated for a second or two) then return to normal. Then the keyboard/mouse wouldn't respond and I switched USB ports, it would install the device, then work. As soon as I shut it down and turned it back on, it didn't recognize the keyboard/mouse again. Eventually it would stop providing any video or power the keyboard/mouse. I tried to reseat the RAM in different slots and independently all with no success. So I RMA'd the board assuming since there were so many issues, the board was most likely the culprit. The replacement arrived today, I connected everything and I have the same issue of no video(monitor which I have confirmed works shows no input connections), no power to the keyboard/mouse. I've tried replacing the PSU with a known working one, same issue.

Any thoughts or suggestions that I may have over looked? In reading the reviews on the egg, there are multiple people who received a board that went bad or was DOA and the RMA'd board was DOA as well. I know that's a possibility/probability, just curious if anyone has any additional thoughts. Thanks in advance.
