Have you tried to re-install the latest drivers
First download the latest amd driver
and catalyst package and save it to your desktop. AMD Graphics Drivers & Software
Once this is done
Remove your ATI software normally through programs and features in the Control Panel using the Catalyst Install Manager (CIM). (Also called AMD Catalyst Install Manager) Reboot the system in Safe Mode (F8) and do the following:
1 - Delete all ATI folders in C:\programs files and C:\programs files (x86) as well as the temp ati folder usually located at c:\ati
2 - Go to C:\Windows\assembly and sort by "Public Key Token". Locate the following Public Key Token "90ba9c70f846762e" Usually there are only two entries. However, there can be many just be careful here we are only deleting/uninstalling entries tagged with the "90ba9c70f846762e" token. (if deletion will not work right click and uninstall)
3 - deleting these policies in safe mode may result in a permissions error. The entries will only show up in systems affected by this issue.
This means that searching for these entries on systems where CCC is loading properly, should result in none found *(as per ati's dev team)
4 - Shut down and re-start normally.
5 - Reinstall the ATI Catalyst package.
This should fix the problem, if it was driver related, if not post back and let me know.
