Stupid, Stupid, Stupid Computer

I'm pissed off. Yesterrday, I noticed my computer suddenly became very slow. It's not your everyday type of computer lag. It was that peculiar type that gets you wondering what the heck is going on. So I tried getting up the task manager. Didn't happen. Don't know why. So I manually turned the computer off after 10 minutes of staring at the screen. As soon as I turned it back on, it said Windows was corrupted and I tried using the last known settings...Didn't work. In fact the screen turned blue with the message saying some corruption occured. How nice. Turn it back off, And windows was back up and running normal. I ran a virus scan from my Verizon Security Suite. It found no viruses, 5 spywares which weren't too major. I couldn't figure out what was going on...I've always knew I should have done so but I have always been lazy to. I knew since I had the chance, I should immediately back up my data and stuff to something like a disc. So I did, before it would quit working on me. Everything important was copied to my disc, except for my 1033 songs. I'll just have to freakin' upload them back from my ipod with Podshare software...When I get my computer back up or get a new one. At least I didn't lose my two American History essays I worked on yesterday. Hm, I had a feeling that all this time my main computer had been a bit whack, especially the harddrive since it kept saying it went over the capacity.Which I found out was not true cause i checked it. Don't know if I can finish the rest of the remaining 3 (or 4?) essays for American History by Wednesday since the only computer left is my little brother's. He won't always let me use it though so that's pretty much nothing. I'd love to just start with paper and pencil but I need the computer for references and info, plus there's no time for drafts. UGH! Why does my computer have to die on me at the wrong time?! WHAT THE F&*#!
