Depending on the make and model, there is usually somewhere on the motherboard, a jumper which resets the BIOS.

Sometimes it is a jumper plug attached to pins, on others it is two pads on the circuit board, which you short out with a wire or tips of tweezers.

They usually put them where you can get at them without too much dismantling.

A good place to look is under the memory modules.

It may be marked cryptically on the board, as something like 'rst'

It will reset everything back to factory settings, even the clock, but it should then boot up OK and you can then reconfigure it.
