I have two 7850's installed, and my system recognizes both cards perfectly fine; I've tried connecting my screen through either of them, and even tried switching them around, and confirmed they both work. However, as soon as I connect the crossfire bridge and boot up, there's something noticeably wrong - first I get stuck at the "Please Wait..." screen before I can login to windows for about 30 seconds, and then as soon as I login to my desktop, Aero is disabled and I see a ballon that says Windows Failed to Connect to a Service. If I go into CCC, the "Enable Crossfire" checkbox is checkable, but it doesn't work - once I click "Apply", it just reverts back to disabled. I'm only running on one monitor, and I've uninstalled and reinstalled my driver a few times. Nothing seems to be working. As soon as I remove the crossfire bridge, everything is fine but of course just on one card. Has anyone had this problem before? Please help me, thank you.
