Something is very, very wrong.

I just logged into my Windows XP computer to find that my background was changed to a blank blue one, my picture folder and any other personalized folders (bookmarks, etc) are gone, and some of the options themes have been switched to what looks like a Windows 95 style.

What in the heck is going on?

I went to see if I could do a system restore, but it said there were no points to restore to.

I re-started the computer several times with no luck.

Any ideas? :confused:

Update: When I click most programs, I get a 'Invalid Parameter' message.
