New installation of ATI HD3650 graphics card not recognised by Win 7
I have just installed a new ATI Radeon HD3650 PCIE 1Gb graphics card in my HP dc5750. At the same time I replaced the 165 Gb HDD with a new WD 465 Gb drive and did a clean install of Win 7 Professional. I have run all the updates, including SP1. The machines has a 2.2 Mhz dual core cpu and has 3 Mb of RAM on board.
The dc5750 previously had no graphics card installed, but integrated video.
All of the above went smoothly and the PC is functioning normally, except that the HD3650 does not appear under Device Manager and is not recognised. It is working, I can tell, as the fan is running (it is noticeably noisier than without the card, but quite acceptable) and what is listed is an AMD High Definition Audio Device within Device Manager.
Before buying the new card, I checked the original spec of this machine - bought new three years ago but not heavily used. The HD3650 was listed as the top of the range card fitted as OEM to this machine, so it should be fully compatible.
I have downloaded the latest ATI drivers, but this has had no effect.
Also, though I have speakers attached, I am getting audio out of one only, since the upgrade.
Any help would be much appreciated.
