So I just finished building my rig, and I'm have a very big issue that I cant fix.. I've tried it all.
I have 2 XFX DoubleD R9 280 3gb Cards in Crossfire, using one bridge between them. Both cards are recognized by
my PC and by CCC as functional.
Now the problem is this, when I open ANY game, the screen goes black, and PC Restarts automatically INSTANTLY.
No warning, No BSOD. (Windows 8.1 64bit)
If I go into CCC and Disable Crossfire, everything works flawlessly.
Things I've tried:
-Disable Catalyst AI
-Force V-Sync
-Force AA
-Two Bridges (causes tearing and anomalies)
-RadeonPro Profiles
-DDU Uninstalling ALL Drivers from Safe Mode and Reinstalling
Things I haven't tried that might work, but I don't know....
-DDU Uninstalling ALL Drivers, Removing Linked Card, Restart, Install Drivers, Replace Linked Card
-Reseating GFX Card or RAM
NOTE: It is not overheating, temps are always low and it happens IMMEDIATELY on opening a game.
NOTE: My PSU is well over capable of powering the cards.
