I have been using ATI since 9700 Pro and have never seen a driver's
release notes say that no reboot was required. Maybe I skipped that
particular version, so post a link please.
Uninstall
Reboot
Install
Reboot
It may take a couple more minutes, but it is the best, safest way to
change your video drivers.
Here's the link from ATI
http://support.amd.com/us/kbarticles...TIProduct.aspx
Notice step 4 - Uninstall any legacy ATI or other display drivers (where
applicable).
Where applicable refers to the fact that there may not be any video
drivers on the machine. In that case, there is nothing to uninstall.
It is the same for Windows 2000, XP, and Vista.
Also note for XP and Windows 2000, step H has this:
h. Click "Finish" and restart your computer.
For Vista, it's step K, and it's written this way:
k. The installation process will be complete once the computer has
restarted.
Look, you don't have to follow the directions. My original reply was to
the OP, who had various issues after over-installing his drivers. After
an uninstall and clean install, they worked.
