I've had this problem for a few days now and it's driving me crazy. Last week I decided to buy and build my own PC for the first time. I installed Windows 7 Ultimate (the 64-bit version) and managed to get the system up and running. Then I installed the motherboard drivers and important Windows Updates. When I try to install the AMD Radeon HD driver, the Catalyst Install Manager asks me to reboot the system so that the driver will take effect. However, when I restart the system, the system freezes during the Windows logo and reboots the system again shortly after. After this, I get a black screen with text saying that I have to restore my system to a restore point before I had downloaded the AMD driver. This 'error' occurred every time I tried to install the driver.
Using Safe Mode (F8), which worked fine, I checked my GPU in the device manager, but the graphics card was recognized. In Safe Mode, I restored Windows and tried both downloading the drivers from the AMD website and the Update Driver option in the device manager, but this also didn't work. I tried to install a newer beta driver of AMD which doesn't work either. My BIOS settings give priority to the PCI-Express GPU and I haven't got the driver of my onboard graphics card installed. However, I am sure that my onboard GPU isn't being used because when I disconnect the AMD card from the power supply, I don't have any display. Finally, I also tried to re-install Windows and download the driver before any other driver was installed, which gave me the very same problem.
I've looked everywhere on the internet and haven't been able to find a working solution. Any ideas would therefore be much appreciated!
