Try updating the motherboard bios.

Do you have a big enough PSU, though I don't think thats the problem, or the behavior that would result, just curious.

Go here and get your bios and just follow the instructions. Try booting your pc with each card but individually and make sure they run normally before running with both. That way you can rule out an immediate RMA before you waste a lot more of your time.
