Hello. I have (2) 7950 graphics cards with an intel DZ68BC motherboard, a 2600 I7 processor, and a 750 watt power supply.
Individually, each of these cards has no issues, but when I hook them both up, my computer crashes after a few minutes. I tried to use each graphics card by itself with the other unplugged and I have no issues on either of them. Freezeup only happens when I enable both. They both show that they are working and the heat is low, so I'm at a loss. I tried the beta drivers, and the regular drivers.
