Problem with swap from 4350 to 4850

[Zach1928]

Ok, so my computer had a 4350 that ran perfectly fine. I just dropped in the new 4850 and now the driver isn't installing properly. Everything comes up on the display, but catalyst control center doesn't work nor does going into device manager And clicking to install the drivers. I downloaded the current CCC through the amd website and set it to simply install the video driver and it finishes with a yellow question mark and and nothing has changed. I've uninstalled and reinstalled several times to no avail, but I was just able to find the old CCC disc that came with the 4350 for version 9.6. My best guess now is to uninstall CCC and reinstall it from the disc, unless anyone has a solution to this issue.

Thanks in advance

On device manager, change display driver to standar vga and restart the computer, once it boots into windows, go to control panel / programs and features and remove everything AMD/ATI related and restart again, this time, install latest catalyst 12.4.
