Installing ATI HD 5650 card on an Acer 5820G

Hi All,

Great forum, been reading for hours, but I still can't seem to solve an issue.

Just freshly installed Win7 Ultimate on a 5820G, that's the designation here in Australia anyway..

Can't seem to get the Ati drivers for the HD5650 card to "stick"...

Would not recognize the card at all at first past a Standard VGA, after disabling "switchable" in the BIOS I was able to install 10.8 Catalyst.

Trying to click CCC it gives the message that the card is not recognized or the drivers aren't installed correctly...? I've uninstalled and reinstalled many times using Driver Cleaner to ensure all traces are gone..
no luck

Is there a system for correctly setting up the HD5650? I'm not all that worried about the Intel HD card, I'd rather have the Ati card functioning correctly by itself...
surely it can't be that complicated.

Any help much appreciated...
