ok so I have a driver issue with my radeon saphire X1650 pci express card and vista worked fine on xp but then decided to upgrade to vista looked so nice on my husbands pc and works fine. I built this one myself. I know its a vista/driver issue cause I uninstall it pc runs pretty fast put it on is slow down extremly and hangs. won't run games. I have a amd 64 fx dual core processor 4 gigs of ddr2 ramm and the card has 512mb 2 hard drives that are 250 gigs each. I got a 32 bit vista but I think I may need 64. I've looked and looked and I find forums with people having this issue but no solution.
