I finally recieved a P5K deluxe and Q6600.
I set it up and powered on - nothing.
I re-checked all the connections, and it powered on - all lit up then powers off one second later.
the obvious cause is a short.
I've put it on a cardboard box and powered it on with no devices other than ram / power / power switch / cpu
Powers on - lights up, fan spins, powers off in under a second, almost as if its shorting.
I did see a simlar thread on this a few days ago but cannot find it now.
I've not come across thei behaviour before.
