this is site is for asking questions related to ubuntu - not for asking about hardware failures that are unrelated. –  RolandiXor Jan 15 '11 at 14:36
    
This does not seem to be related to Ubuntu but rather a hardware issue outside of Ubuntu. While I'm happy to hear you were able to resolve your previous issue you may wish to try a different monitor. –  Marco Ceppi Jan 15 '11 at 14:38

If the bios isn't appearing then your computer is suffering from hardware failure and it's probably not something to do with Ubuntu or any other software you may have installed.

The only other thing other than hardware failure that can cause what you can see is a failed bios upgrade. But it didn't sound like that's what you did as bios upgrades are hard to perform and aren't done automatically.

If it is not showing at the Bios level this does NOT have anything to do with Ubuntu and for that matter any other commercial operating system. It has more to d with hardware failure or Layer 8 problems. Reasons might be:

  1. You turn the monitor off
  2. You unplugged the monitor
  3. The monitor is so old it died
