I haven't adjusted the NB volts yet (I haven't moved it from auto), that was my last trick to try before RMA'ing it. (I haven't really played with the PC for a couple of days:bad a** electrical storms +it was giving me the sh*ts

It's only tonight I've started fiddling with it again
I'm just about to try upping the NB volts and that fails, then I'm definitely calling it a dud and will take it back tmw.
