I have a Compaq Presario CQ5700y (Win 7 x64, 3.1ghz Athlon II X2, 6GB RAM) and I previously had 2 Sapphire 5830's running on it. I built another rig and moved one of my 5830's over there and added a spare 5750 back to my Compaq but it won't recognize the 5750. I've uninstalled and reinstalled different versions of CCC (11-9, 11-10, 11-11, 12-1) and had device manager scan for hardware changes.
I know the card works because if I unplug my 5830 and install the 5750 it works fine but then if I add the 5830 into the 2nd slot it won't recognize it.
Any and all help is greatly appreciated
