I'm running WinXP Pro SP2, and have a Ati Radeon 1950XT PCiE vid card. I wanted to try out the 8.3 Catalyst drivers. So, I un-installed all the old Ati stuff, rebooted, and tried to install the new drivers. However, I got the error message : Setup did not find a driver compatible with your current hardware or operating system. Setup will now exit. So, I then ran Driver Cleaner, and it got rid of all remaining traces of the old ati drivers. Yet still, I get the same dang error. I then tried the Omega drivers, and those won't work either. I cleaned everything again, and tried the old 7.11 drivers, and those won't work either. What's going on here?! My vid card is useless now! Any ideas as to why NONE of the drivers will install now?
