  1. Try resetting your BIOS to defaults. Read your motherboard manual on how to do this (usually a jumper).

    Besides no video signal, does the computer seem to boot normally? Do you hear any beeps, etc?

    No video signal doesn't always mean there's an issue with the monitor or video card.
  2. A "no video" problem can be any number of things. Here's a checklist to assist in troubleshooting your problem. The chances are very good that you will solve your problem if you perform EVERY step in the checklist.
