With XP I couldn't install new version of drivers without installing older ones, made for W2K, first. Intallation proggie checks if there's older drivers in computer and installs new ones IF it finds those old ones first.
Problem was that when I installed those W2k drivers which came in a CD with card I couldn't start my computer anymore without getting BSOD.
Solution:
Crack that driverpack, take updated drivers from there and install them "old fashion" without installing any older drivers first, just like I did in that other post.
Anyway if your system works now maybe you don't have to give your car away
