Ok I'm not sure what the heck happened but I updated my drivers to 13.1 (6 times now mind you, even redownloaded the file 3 times) did driver sweeper/driver fusion in safe mode each time. And each and every time the first time I install 13.1 it says there are errors, but going to the log there is nothing. It reboots seems fine, but I have no Catalyst Control Center. If I reinstall again without cleaning it'll install but not say anything about errors and still no CCC. What's going on? Besides the obvious uses for CCC I need it for the overscan/underscan since my monitor is funky without it.

You have to do the cleaning in safe-mode or it wont have access to active files.

"did driver sweeper/driver fusion in safe mode each time."

I don't get it, I've been doing it several more times since my last post. This time instead of driver sweeper or driver fusion I just re-ran the driver installer and chose uninstall. Restarted, reinstalled and it worked this time. I have never had a problem with driver cleaners before...

It is strange that installing after a thorough uninstall caused Control Panel not to install, but the only time I use Driver Sweeper is if the current driver install has been borked somehow. Normally I just uninstall via Programs and Features and install the new drivers after rebooting.

I've read comments from others here who don't even go that far. They just install the new right over the old.
