George, what psu do you have, is it possible you are drawing too much amps on statup.
Cpu

That could be possible due to I have to plug both cards in seperatly and there is a 4 pin molex also that needs to be plugged in when 2 graphics cards are being used. My Ultra power supply has a strong 34 Amp 12v rail. I did adjust bios for the added card. I have the Ultra Products 500W.
George:

Happy to hear from you again.

I would suggest a PSU upgrade / 500 watts is marginal for a dual core CPU system with two video cards / you might have got away with it had the PSU been a real High quality unit / but unfortunately the Ultra brand doesnt get thrown into that catagory !!

I strongly suggest and Enermax of atleast 600 watts and make sure its an SLI ready model (check ebay) if you are squeezed for dollars you might save a little with an Antec PSU / Antec is a good unit but not really up to the standard of a Enermax >> with that power hungry beast I wouldnt cut any corners >> but thats me personally :)

good luck and keep us posted on how you progress
