System Restore is a good suggestion if it isn't turned off. It isn't perfect, but can be helpful if applications were changed. I wouldn't think it would fix a corrupt file allocation table, though.
To get to it without the Start button, go into your "My Computer" icon and go into the Control Panel there.

I'm inside the control panel under "system" -- I can't find a way to restore, though. I have 4 tabs: hardware, advanced, system restore and remote. When going to the system restore tab, there's not really an option there to undo anything. Perhaps I'm looking under the wrong icon/tab in the control panel. Thanks again for your posts, everyone.
