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.

Any suggestions??

Please advise

What make and model number is you PSU?  It sounds like it may be drawing too much power under load.


Is your setup crossfire?  If so, undo the crossfire but only use one card with both cards plugged in in n on-crossfoire setup.  (not just software disabled, but unplug the crossfire jumper)
