Hello all.



I want to attach 3 monitors to my computer, but discovered that i had to have an active displayport to hdmi converter if i wanted to do this with my 5770 card. So i then installed my old, Radeon 4650 card in my computer, and turned on the computer again. It booted up, and the drivers for the 4650 card were installing. A minute later, windows prompted me to reboot. After the reboot, the 5770 card was not working, and i was not able to run Catalyst Control Center. It told me that there were no working drivers for this card. (which have always been working).

The new drivers for the 4650 card is called:

ATI Radeon HD 4650 (Microsoft Corporation WDDM 1.1)
Im afraid that installing original drivers for the 4650 (if standaone drivers exist), will mess my system up, and cause the 5770 card to not work...BUT i could be wrong..



So my question is: How do i get these two graphic cards working at the same time? Do i install the catalyst software suite, which is compatible with the 4650 cards? Or is there a way to get my previously working CCC install, to run with both cards?



I am running windows 7 64bit.



I really hope someone can figure out this problem.



Thanks in advance.

Daniel

You will need to uninstall the default drivers Windows has loaded.

First step would be to go download the latest catalyst drivers from AMD/ATI. Uninstall the default video drivers, then run the catalyst setup. It should install drivers for both cards.

Thanks Eximo.. sorry for the late reply, but i got help at the ati amd support forum, and they told me to install "12-4_vista_win7_64_dd_ccc" these drivers. They are the latest drivers that support both cards. Still thanks a bunch for taking your time to give me a reply!
