by the way, if you still wanna reset the BIOS, here's how to do it:
You'll have to remove the Cmos battery (a round battery similar to those you find in watches) for at least 30 min. and the next time you start the computer the BIOS will reset.
The only problem is that the computer won't go into bios, the power cuts off before the screen even turn on..
