computer woes

[unfloopy]

My laptop has decided to freak out on me. It has not lost any files, but it's lost all and any kind of configurations to anything at all. From desktop to firefox extentions. It's annoying the hell out of me. And, if I change anything and restart the computer, it goes back to state 0 again. Like if I had just turned it on for the first time or something. Plus, it's so much slower too. I've run antivir and it doesn't catch anything. I have no idea what's wrong, and neither does anyone else I've called. So. annoying. My aunt thinks I'm gonna need to format it. So I'm trying to do a backup of all my files, which I've done, except for music files. And that part is pretty much gonna take me all night, huh? So. freaking. weird.
