AMD will not recognize correct graphs card

Hi,
After a fresh win 7 OS install, my AMD graphics properties now recognizes the Radeon hd 6520g as the primary graphics and the hd 6750m as the linked?
In the sys tray, AMD settings control, it has the hd 6520g set as both 1 and 2. 1 has the normal 3d settings control with which I can change, but this again is only for the hd 6520g , number 2 says "extended desktop only" which seems to do nothing when clicked.
When I play games you can tell its only the one graphs card working.

Normally with AMD systray control options 1 is the primary driver (hd 6750m) and 2 is the secondary (hd 6520g) and both had separate control settings under the AMD sys tray, eg mipmap detail etc.

Normally after a fresh OS install all I have to do is click windows update which finds the Radeon hd 6750m and hd 6520g drivers (I CANNOT FIND THESE DRIVERS ANYWHERE ON THE WEB, for my machine) and install. I then install, from official hp site, the corresponding AMD cata suite and it has been fine in the past.

I'm thinking there is a reg file or a AMD file somewhere that is not getting deleted with the the fresh uninstall and this file is keeping incorrect settings and over-riding any fresh installs, I cannot find it myself, other than that I have no idea.

I downloaded (AMD uninstall) and retried a fresh install of catalyst, didnt work, I used uninstall again and tried the AMD beta cata suite and pretty much every compatible driver I could find but it always only recognizes the Radeon hd 6520g as the primary and secondary as I mentioned earlier, I just cannot get AMD to recognize the right graphs cards.

I have an HP Pavilion Dv6-6b00AX (Australian model), A6-3410MX quad, with duel radeon graphs hd 6750m (Primary) and hd 6520g (secondary, less powerful card).

PLZ help, Cheers!
