Computer Problems

I really hate it when your computer works fine, and then suddenly one day things just go nuts and you can't do anything. Today my quick cam just decides to go AWOL and whenever I'm running it, it uses 99% of my CPU cycles. This is obviously bad, and I do not know how to fix this. Thus, VitaVision will be off the air for a while until it's done. What bothers me even more is that I'm the type of person who can't do ANYTHING until this damn thing is solved. So basically this just sucks. Well, at least a few people got to see me on it before it went to poop.
