Got myself into a pickle... I am upgrading my X800GTO to an X1900XTX. After I removed my X800GTO, I realised I hadn't removed the drivers first, so I put it back in and now it doesn't work (my bad - and that's not the problem). So I'm forced to install the X1900XTX with the X800 drivers installed (XP, can't remember the Cat driver version). Question - can I do this? Is there a way to uninstall drivers via safe mode or other means?
