Ahhh please tell me nothing bad has happened as 1) I only finished building my PC two months ago, and 2) I need my machine working.

Basically I turned round and saw a big blue screen in WinXP Pro.
It said something about an error and it was now dumping the disc or something like that.
I've never had that before.
Anyway, nothing would move so I rebooted and now I cant get anywhere past the Pentium4 screen and it sits there and sometimes says disk error. Reboot by pressing ctrl alt Del.

Whoever can help me here, I really need your help.
I neeed this machine working again ASAP.
I have spent loads on it and don't need this happening to me right now.

Thanks for any help.
