9600GT SLI produces RED shadowing...

I have 2 9600GT's both made by EVGA both Have exact same picture on shroud, but one is dual width and other is single. Now I tried them both SEPARATELY (in the PC at once) and BOTH work FLAWLESSLY) however when ever try to SLI them and then play a game I get RED Like shadowing over EVERY part of the game. Its like a red tinting and its just...weird. Any Idea whats wrong?? I only paid 30 bucks for the dual width card, so not too big a loss if its bad. Thx guys.

EDIT::
I have a corsair 750CXM as my PSU so I think im good on juice.
