Hello, I recently decided to upgrade to Windows 8 Pro. I did a clean install and installed the latest CCC drivers (13.1 rev) and when I attempted to install it would crash through set up and I would receive a BSOD. I finally decided to pull out my second card and just start with one and it installed perfectly. Then I shut down and put back in the second card and attempted to enable crossfire. I received a BSOD again. I don't know what to do. I tried reverting back to previous drivers but none worked. Same problems.
