Asus GeForce2 GTS 32MB with KT7A Raid

I have the KT7A Raid motherboard and recently bought the ASUS GeForce2 GTS 32MB DDR card. First, I had put in the card and installed the drivers, then restarted the comp and when windows started loading the screen went whack and the colors embossed. Then the computer restarts and repeats. So, I took the card back and the place tested it and it worked for them. So I called ASUS tech support and he said it sounded like a card problem. So basically at this moment no one has helped me and I need to get an answer. Please, any info offered will be apprechiated.
