Make, model and since you did make it to the BIOS screen did you change the boot order (sorry but no make or model so advice must be generic) to boot from the CD/DVD first?
Tell more. Tell what the words in red ask for. Tell what boot disk or dvd you have to work with. And tell what words you see on the screen.
-> And JUST IN CASE. Have you cleaned your machine EVERY YEAR? Example at http://reviews.cnet.com/4520-11319_7-6240575-1.html

I was hit with possibly a worm,If i boot my sysytem normally,it goes to the desk top for a second then a blue screen with a bunch of words and it does a count to 90 seconds and does a memory dump then shuts down.I have tried in safe mode numerous ways,no change..I tried other options for debugging and windows did a disk check.all ok..I tried to use f12 to boot from a disk but i have to use f2 and the screen pops up for a second then goes right to the bios,so i can't seem to do anything.. I am running vista 64 home
