My Computer is F'ed

Seriously. On Thursday it was working fine. I went to lunch, and when I came back it was making a rattling/grinding noise. One of the IT people was foolishly walking by (okay, why do these people even walk around the office? They KNOW they're going to get stopped at every other desk!) so I grabbed him and said, "HEY! Listen to this. Should I be worried?" He said, "Whoa. You better back up everything RIGHT NOW." I was like, it seems to be running okay, just making this funny noise. He said it sounded to him like my hard drive was going to crash...any minute!!!!! Ahhhhh!!!!!! So I backed up everything onto the shared drive real quick and waited for my computer to blow up. It never did. So I thought, well, I'll bring in some blank discs tomorrow and back everything up on them, so that my dog photos won't be on the company mainframe for all of the office to see. I've tried 4 different blank discs and the computer starts copying the files, freezes up, and says I have a defective disc. Whatever. I know it's my computer. I'm just going to have to sit back and wait for the smoke to start pouring out of it I guess. Maybe I'll get a new laptop? Yay!
