All updates are done and I've uninstalled all the ATI software and drivers. When I reboot, Windows detects both graphics cards and installs drivers.
When I come to install the CCC software it goes ok until the screen goes black and into standby mode - i.e. there is no longer an output from teh graphics card(s). I've tried plugging the monitor in to both outputs on both cards with no result.
Not sure if i have an answer, but i have been running win 7 for nearly a week now, and i found lots of issues with the black screen as you mentioned, i eventually traced some problems to the power management settings. by default, the screen was set to sleep after 20 mins, but would not wake up, the setting also required a password to continue.
So try going to screen preferences and switching all the timers to 'never' i got the OS to stay alive a lot longer since.
So far, my experiences with this RC version, i find it very unstable and prone to crashing.
Ok, problem solved. For whatever reasons the primary display adapter was disabled in device manager, so when W7 came to load the ATI display drivers there was no display device to use, therefore sending the monitor in to standby.
