After arcthelad00 took a shot at troubleshooting my PC earlier, we determined it was the motherboard. So, I'm still going to try to use the warranty on the current one, but we went to Fry's and I bought a new abit AN-M2 so I can have a working computer again. It involved SATA converters for my drives too, but what the heck. If I do get a replacement via warranty on my MSI board, we have a spare motherboard at least.

Patrick is now attempting to put the PC together.

Hopefully the differing chipsets won't screw anything up, but I'm completely willing to re-install everything after I grab my important data off the C:/ drive.
