PC locks up when disabling crossfire

[Heisenberg]

Hi guys, just a quick one. Has anyone ever had issues when disabling crossfire in CCC has caused there PC to lock up to a black screen? Trying to play Titanfall beta but getting texture flickering which i've read is due to crossfire. Running the 13.12 WHQL drivers. Thanks

Yeah, it happens occasionally for me too. Just hit the restart button and it's all good.
You could also just make a profile for that game.

Think i've solved it. In my BIOS i had onboard set to auto. Setting it too off seems to have cured it.
