Nvidia Video Driver Keeps Re-installing!

I just reformatted my pc and for the first time installed SP2. Well, evidently SP2 had the driver for my video (on board Gforce) and went ahead and installed it. I had the latest Nvidia Gforce unified divers on hand that I downloaded from Nvidia and those are the ones I wanted to use. The problem is, when I go to Device Manager to delete the SP2 driver and reboot, Windows loads it right back again. I tried this several times and it keeps doing it. How do I get rid of it to keep XP from loading it back up? I need to keep it deleted to load my most current drivers. Thanks.
