Hello, I was having issues with my new computer shutting down b/c of the video card and tried to install driver updates off the CATALYST website, but choose the wrong ones. I have a 3800 series and installed the 4000 series update. Now I get odd errors and it wants me to register the 4000 series card. How do I find and remove the update?

you might try system restore and have the correct update drivers ready.
