Thanks, Harper and Ste. At this very moment, I pulled out the RAM and battery for the motherboard and am letting them sit for about 5 minutes so the CMOS can reset and so I can start fresh. I have another CD-ROM on hand for that and it's near the box, waiting for power and IDE strength.
This computer's been an interesting tale. First, newegg.com sent the incorrect RAM for his computer, assembly was interesting. He didn't mount his PCI-E video card properly (Didn't get the little notch that's supposed to hit the gap in the card) which I fixed, and then he set up the wires incorrectly for his power, reset, and hdd led. Now, Windows is being a bastard. Fun fun fun.
Oh well, thanks to y'alls suggestions, I'll hopefully be able to get him up and running. I've never had these Windows install problems before and that's what perturbed me heavily.
Thanks, everyone. I'll report back in whether it works or fails.
