Are you running ATI 5870, 6870 or Nvidia 460?

Perhaps your method of updating is incorrect? It is easy to lose your way during the process.

Basically it's only necessary to use the Ati Catalyst Install Manager. Access that via Start/ Control Manager/ Uninstall or Change (Win 7). Highlight the above Manager and click Change, then select the Express uninstall option in the resulting window. Once complete carry out the requested reboot.
Once rebooted, find the new Catalyst Install.exe (that you downloaded before the above, right? ) and execute. Allow the process to run, allow the new folder to be created, and then reboot when asked to. This should bring you back to the previous settings of your desktop.
There is no need to mess with registry settings or manual deletions - this can cause more problems than it solves.
