Video Card crashes

[Diek45]

I have Radeon Sapphire 3870's two of them connected using crossfire in my computer.
For some reason, whenever I load up a game, no matter what it is, about 5 minutes in, the video card stop responding and crashes the game.
Only when I'm in crossfire does this happen, running just one of the cards works just fine.
I'm not sure if it is a overheating issue or not, the temps idol are at about 45 while the load is at around 73 maybe a little less.
I've cleaned, and dusted my computer out recently so air flow isn't a problem inside the case.

What are your specs?

Could still be temps? don't know ati, but maybe power.

Have you got the most recent drivers?

q6600 quad core
P5E x38 Mbo
Corsair 3 gigs, cant tell ya the name without popping the case
950w psu
2 3870 radeons
Is 73ish too high to be running those cards?

What psu brand and how much watts, rtho 950's more than enough usually.

73ish is high, but invidias are rated over 100C, so.

What about drivers/catalyst?

Tagan BZ its actually 900w, but still.
I have the latest drivers, 9.4 this is a recent problem, I've had this computer and specs for about a year and a half and this has never happened before.
I've tried rolling back to older driver versions but those prove to be unhelpful.
