I installed the WHQL 21.83 drivers fine throught the detonator's setup.exe. However, I can't install the newer 22.80's or 22.40's. I do a manual install, and It tell's me that the drivers don't pass the logo test or whatever. I install them anyway, and in the end it tells me there's an error. I restart, and the videocard is disabled in device manager. ???. I then "remove" the device from device manager and restart, then winXP successfully installs the previous 21.83 drivers. This sucks.
