Pulling a card out while installing drivers!?!?!? WTF ARE YOU DOING!?!?!?!?!!?
Install 1 card with new drivers. Make sure it's good to go after all restarts. Then, shut down, install 2nd card WITHOUT bridge. Let the drivers catch up. Shut down. Install additional cards 1 by 1 in a similar fashion. Once that's all done and good, shut down, pop on bridges, boot, go into CCC, and enable CFX.
See? Really not that hard. I think whoever told your friend how to install CFX was an nVidia fanboy trying to get him to kill a car...and he succeeded. NEVER pull a card out while the computer's on!!! I think you and your friend need to go beat the shit out of whoever told you to do that...
