OK.
Let us know.
BTW, my ATI drivers have a removal tool, the first ATI thing mentioned in Add/Remove programs.
When I click it, it removes all ATI software from my system.
You might want to try that, if you have it.
Another thing - when you reboot after uninstalling the display drivers, it'll be in a low resolution.
Don't let it bother you, it's normal.
Once you install the new drivers and reboot, it should go back to normal resolution - if it doesn't, just set it manually.
