I recently bought a Radeon 7700, after I put it in my computer (I also have my old Graphics card in Radeon 4670 ) it wasn't showing me the 7700 GPU's fan speed or GPU temp. So i uninstalled the Radeon 4670's Driver and reinstalled the 7700 driver and it worked, it is showing both fan speeds and temps for the graphics cards. but not I am getting an error message:
Invalid Monitor handle.
I also have a monitor on each card. could the drivers be clashing againced eachother??? Nothing else is wrong other than the error message...
