Well I have been having an ongoing problems with my dual XFX 6870s in a crossfire situation that I can't seem to figure out how to fix. Sometimes, at completely random times, the fans of my graphics cards turn all the way up to 100% and then shortly after my computer screen goes black.
At first I assumed it was the drivers, so I uninstalled + driver sweeped my drivers and then downloaded ccc 10. This worked for about a week then the problem started happening again. I moved back to ccc 11 and again it continued to happen.
After I realized that uninstalling/reinstalling the drivers wasn't going to work I decided to try flashing the card bios's. So I individually flashed each card's bios to some Asus BIOS which didn't seem to help very much at all.
At this point I realized that I had no other choice but to reinstall windows. So I backed up my data, formatted all of my disks, and reinstalled windows on a different hard drive. This worked very well for the past ~2 weeks. Today for the first time I turned on Crossfire and began reinstalling all of my games and about an hour ago the fans again went up to 100% and black screened.
Individually, each card works fine. I have used both cards and neither seem to have any issues working individually, however once I turn on crossfire a crash is imminent. I also have changed crossfire bridges. One other side effect I noticed is that on my non primary card catalyst control center is never able to tell me the current fan speed or temperature. The fan speed stays at 20% no matter what I do and the temperature stays at 0 degrees.
Is there anyone who has had a similar problem that would be able to help me out or help me to discover my problem? Any assistance would be very much appreciated in this extremely frustrating matter.
Update: Now suddenly catalyst control center doesn't even recognize the other card. It thinks that I am only using one card for some reason. It is also getting even worse, sometimes the fans start blowing and the screen goes black immediately upon turning on the computer. This is growing even more frustrating.
