WOW and COD frame loss

I have the strangest issue that I’ve been having with WOW and COD: Black Ops. So the games would freeze up and have serious frame issues, here’s where the strange part comes in when I hit the windows key they stop losing frames.
I was able to fix WOW frame loss with one of the tech tips on changing the folders names in the WTF folder.
I still have a problem with Black Ops however. Anyone have any idea what is going on or a fix for the issue?
