This is not the thread for your sort of issue, but Admin permitting, I'll post a one shot possible solution to your problem. Try it and if it doesn't work, start a new thread in the appropriate place with your details... and the fact that the below didn't work.
------
1] Download the latest Driver Sweeper from
here, save it wherever you want, then Pin it to your Start Menu, for ease of use purposes; as in when your resolution is all fucked up and your desktop is squished, you can just launch it from your Start Menu.
2] Download the latest Catalyst Driver from
here, and the latest CAP from
here, save them wherever you want, then Pin them to your Start Menu, also for ease of use purposes.
3] If you have any profiles you want to save, copy the ACE folder located at C:\Users\YourUserNameGoesHere\AppData\Local\ATI\AC E somewhere else.
4] Run the Uninstall program for whatever Catalyst stuff you have installed from your Control Panel > Programs and Features menu. If you have both drivers and CAPs installed, uninstall the Application Profiles first, ignore the warnings to restart (Click "No"/"I'll do it later"), then uninstall the Catalysts last. Restart when the CATALYST uninstall says so, and boot...
5] ...into Safe Mode, run Driver Sweeper, analyze ONLY the AMD-Display option, Clean whatever it finds. Restart when it asks you to, boot into Windows normally.
6] Run the Catalyst driver from your Start Menu, blah blah blah, restart, boot normally, run the CAP, blah blah blah, restart, boot normally, enjoy your working system.

You're welcome.
