Sometimes, you have to (and I don’t know why) do a BIOS update. The reason could be one of the following: MB problems, new feaures added, you are just bore.

You have downloaded (and you are sure about this) the proper BIOS version (the last stable version) for you MB. But, after reboot the computer doesn’t want to start.

Now, there are four possibilities to recover:

  • Do a short clear CMOS as described in the MB’s manual;
  • Do a long clear CMOS (I read that it might help), I not so sure about this, but, anyway: unplug the power, remove all unneeded hardware (video card, HDD, FDD, etc) put the jumper in the clear CMOS position, remove the battery and wait at least 12 hours;
  • Remove unneeded hardware, replace RAM with the newest you have (533MHz with 667MHz, e.g.), this tend to be so common;
  • Buy another one, because the new MB have the BISO chip soldered and it cannot be removed to be rewriten.

You are lucky if you MB give sound alerts or it has LEDs. Try to interpret this information using the Troubleshooting section in your manual.

As a backup measure you verify if your MB have dual BIOS or quad BIOS feature enabled (as gigabyte have), or something similar.

Good luck, you need it.
