tried another psu today, granted its a bit of a crappy one but thats all i could lay my hands on, but still no go.
it does exactly the same thing, it spins all my fans up, you can hear the harddrives start to whurr but after that it does nothing more. so thats 2 motherboards and 2 psus ive tried. hmm. i dont know what to do now. as it worked for 2hours or so yesterday fine with my old psu and new motherboard, then just decided not to post after i tried to reset it.
this is getting frustrating now >( although i am getting pretty good at typing fast on a laptop keyboard!!
