Loading Cursor not going away?

For the past few days my cursor shows both the arrow and the loading cursor (the hour gl) next to it. I have restarted my computer many times, I have left it off over night, yet I still have the same problems. A few of my other programs such as CCC (ATI video card's program) won't open either, something to do with missing DLL's. Would this be the cause of the problem? Thank you in advance.
