Hi.
        This is where the tiny boards which decode bios port writes (usually
to port 80H) are useful. If you see codes, the mobo and all is not dead. You
should get one.
        In the meanwhile:
        -Measure PS voltages.
        -Use the reset button.
        -Take the PPro out and observe the led (probably no change).

Starting point:        (-1)^(-1) = -1
Applying logarithms: (-1)*ln(-1) = ln(-1)
Since ln(-1) <> 0, dividing:  -1 = 1
     (ln(-1) is complex, but exists)
