I am running: Intel i7 975 3.33 GHZ 6 GB Kingston Hyper X DDR3 2X EVGA 295 Red Edition SLI P6T Mother Board (non deluxe) Topower 1100w PSU 300 GB Velociraptor Hard Drive Win 7 64 Bit All Nvidia Drivers are up to date ( new) Here is my Question: When I try to play Games in SLI I get flashing green and purple. :cry: When I use one card alone or both at the same time in Non SLI mode the cards work great. I used to play on this motherboard in SLI no problem but now it doesn't work. Any thoughts. I cant seem to fix this problem for the life of me but I think I have figured that the problem is not the graphic cards since I can use each one on its own no problem.
