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.
