Well, if I understood correctly one of your post, your 2 GPUs were on 2 separate PSU so if they run fine alone, then it should not make a difference if they run together (PSU wise). Are they both directly on the motherboard or you are using PCI-E extenders? Make sure that they are well seated in their slots. I can't think of anything else right now. I don't know if it does still make a difference but if you have crossfire, disable it.
