Thanks - for step 1, the PS 12v connector is 8 pin - the MB is 4 pin. I have it plugged in to the 4 pin connector and the4 unused pins are not contacting anything else on MB. All hardware is brand new and I dont have any standoff/loose wire problems. The speaker is a standalone gizmo that plugs into the mb speaker conn & looks almost like an old capacitor. I haven't tried checking voltages yet on PS but am running video from onboard - no video output at all - no beeps on speaker - runs the same whether memory is installed or not . I'm guessing if must be a doa MB problem. I have cleared cmos. I may check PS voltages in the morning tho. - can also test the speaker on an old mb.
