Problems installing windows xp on a gigabyte ex58-ud3r

I can't install windows xp on my new computer. I have a new gigabyte ex58-ud3r motherboard, i7 920 at 2.66, 6GB Kingston 1066, two 640 GB WD Caviar Blacks in an Antec case. I can install 64-bit Vista fine, no problems at all, but I am a chemist and need to run some programs in XP. I've been trying to install 32-bit XP (I have Professional, SP2). Can't do it. For one the Windows setup screen see two 128 GB hard drives when I boot to Setup. If I format one using Setup, my computer dies when it restarts the machine during setup. I tried removing my hard drives, installed my friends old 180GB and tried again. Initially, I booted to the XP on my friends drive just fine. When I reformatted the drive and tried to install a fresh copy of XP, I would get a blue screen of death when the setup would restart my comp. Any suggestions? Similar Problems? I am thinking about buying a new SP3 XP but I am a poor grad student and would rather not. I already spent way too much!
