[ILUG] Dead BP6

[Philip Trickett]

By the way John/Kate, did you have your CPU's plugged in at the time? (Mind
you, I suppose you would ahve, seeing as you were fitting a heatsink!) Have
you tried the board with just one cpu, and then swapped them if it didn't
work.  You could have killed a CPU instead of the board.

Here's a thought:

Could there be enough power left in the capacitors in the psu to blow your
board 
(and not in a fun way) even when the box is plugged out?

Should you maybe hit the 'on' button to bleed 'em out or disconnect the
power to 
the mother board before attacking it with screw-drivers?
