This is going to be a bit cheeky WhiteTruckMan,il test a socket 478 mobo for you Lol,i have a dead system here and really want to get it up and running and i have been advised the mobo is dead as everything else has been replaced.
So if you have a spare kicking round,let me know LOl ha ha
I know !!!! cheeky git :-)
Regarding your question of shorting out the pins on the power supply,Fruitbat advised me of this trick...sadly i had no joy with that either,even with a new psu.
