Hi, I'm running 2 4870 1gb in crossfire with Catalyst 9.4, and I'm getting BSOD on Call of Duty World At War when I have crossfire enabled. The cards do not appear to be overheating. Problem is gone when I disable crossfire.

I'm trying to figure out if the second card is having issues. First card runs fine alone, however when I try to use the second card by itself, the game crashes. Is there a tool I can use to test the second card for any issues?

My PSU is an Antec Truepower 850w.

Any help would be appreciated, I can't figure out if its a problem with the video cards, or could be windows 7.

update: just tried the game again, and it no longer crashes. I can't find indication the second card is defective. I can only assume something is wrong with my crossfire. Any chance that the PSU isn't enough and it's causing my BSOD?

its probably just a drivers issue. remember that windows 7 is still pre-release, so not all the bugs are worked out of it and its drivers yet. do you have the same problem in vista or only in windows 7?
