"..the down side is that when this power supply goes, it changes the polarity of the motherboard - so when it goes, the motherboard goes..."

Join the club. You can hold the power button down for 10 sec to refresh the power cycle, remove memory and try to boot to get the board to issue error codes but having tried all this, its dead. Just don’t know if memory is gone and/or processor until the board gets replaced.
