yay i'm posting a thread with centric in the title!

last night i was using my computer and i had just put some mp3s on and a began to prune my nails, and itt suddenly crashed with a blue screen!

it had some kind of error message and said if this was the first time it had happened, to restart my pc, at the bottom, it said beginning dump of memory, so i turned my computer off, waited a few seconds and turned it back on. to my shock it said it could not find the hard drive.

i tried F2ing it but it couldn't find the drive.

have i got a deadly virus? or should i change the jumper settings? what's happened?
