Hi. Do you see a BIOS screen? If no then something bad is wrong. If yes you may have a hard drive or OS problem. Try booting from CD with your install CD. Or have someone download and burn a BARTPE disk and boot from that.

Answer 3

You probably have a virus and can try booting up with a Norton Anti-Virus CD. When booting up put in the Norton CD and when you hear the cd-rom making the "reading disc" noise press down or 2 on your keyboard and press "Enter".

Answer 4

sounds like its coming on from what you said, and could be a number of things but i would suspect its your video card.
