I just finished a clean install of Windows 7 64-bit and now Windows can't install the 14.4 AMD CCC drivers to my video card (HD Radeon 7850). However, this same driver suite was working fine before I re-installed Windows. Suggestions?

Yeah I'm getting "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31)" in device manager under my video card. I'll try the install path thing...

Make sure the video card is seated in the PCI-e slot correctly so that it is detected by Windows, and the power cables are connected to the card. It sounds like some type of hardware error since your system was just built.

I tried installing again, and it failed again. I'm getting an error message from CCC that says "No AMD graphics driver is installed, or the AMD driver is not functioning properly. Please install the AMD driver appropriate for your AMD hardware." I tried going back to the 13.12 drivers, but those failed as well when it got to installing the HDMI audio driver. It was a critical error that yielded a blue screen of death and prevented windows from starting at all. I had to run windows repair to get back in. I'll try the 13.4 drivers.

Paul, I really doubt it's a hardware issue. This is not a newly built system. I just re-installed windows in order to solve a different problem that was network related. The re-install fixed that problem, but seems to have caused a whole new nasty one. At any rate, the video card and drivers were working fine before the re-install.

Corroded, I've uninstalled everything. I used Display Driver Uninstaller to completely remove all ATI remnants from my system and tried a completely clean install and still no dice.

hmmm... is there an "Onboard GPU" as in a video plug on the mobo? if so, pull the AMD and boot with the onboard into safe mode and makew sure the rest is uninstalled.

Power down and carefully seat the card... boot up and set theAMD in the BIOS as primary video and see if it is detected.

when you install the drivers I assume you downloaded them from amd site to a folder on your desktop and installed from there? when you uninstalled the driver from the programs and features using the catalyst install manager and when the pop up asks ''remove all amd stuff '' you click yes when finiched uninstalling the screen flashes and the card reverts to the generic vga driver that's built into windows?? if so you reboot and when your back to desk top the card is still using the default windows vga driver then you open the folder that you down loaded the driver into and run the install from it ??

So you're suggesting the card might not be seated properly? There is an onboard GPU. It's referred to as "AMD 760G", which is strange, since it was called "AMD 3000" or something like that BEFORE I re-installed Windows. Now, this is after I installed the (supposedly) proper chipset drivers for my motherboard. Also, every time I try to install new drivers from AMD for my card, it crashes to a blue screen of death whenever it gets to the installation of the HDMI Audio driver. This has happened with the 3.1, 3.4, 3.9, 3.12, and 4.14 driver suites. Something is obviously conflicting with the audio drivers, but I don't know what. Are there any other types of drivers I should install after a clean Windows installation that might solve this problem? And I'm not exactly sure how to set my 7850 as the primary video using BIOS.

Well, I've actually been using "Display Driver Uninstaller" in safe mode to completely uninstall the drivers, but everything else you said is pretty much what I've been doing, yes. As I said above, the generic vga adapter is called something different that what it was called before. What could cause that and is it important?

heres what I never understand in the drivers footnotes it explains the proper install/uninstall and other things to know. but seems like most don't follow this and do these other things and end up with issues

also scan this and see all the happy folks using this driver
