My roommate is pretty computer savvy and says that I've most likely been hacked and have a key-logger. He won't have time to work on my computer until this weekend, and was kind enough to lend me his spare laptop in the meantime (I would go stark raving mad going more than a day or two without computer access). He says if he can't get into the Bios to turn off or change the password, he will have to completely wipe and reinstall it.
I guessing you have not ever bothered to make a password reset disk..
Your room mate might claim to be computer savvy but if he says that getting into the bios has anything to do with changing the windows password he does not know what hes talking about.
The chances of a hacker getting into your computer and changing your password are very , very remote. There's no motive for a start, what would be the point?
Most of the time this is caused by the caps lock being on or even a dodgy keyboard.
