Today I upgraded my Samsung 3 Series operating system from Windows 8 to Windows 8.1, and after the upgrade, my AMD Radeon HD 7670M graphics card became disabled. When I look in the Device Manager window, the card now displays as AMD Radeon Hybrid (Blocked), and the error message reads "This device is not working properly because Windows cannot load the drivers required for this device. (Code 31) The driver trying to start is not the same as the driver for the POSTed display adapter."
I uninstalled my current version of Catalyst Control Center and attempted to reinstall the latest version, but now when I run Catalyst Install Manager, the driver does not get installed. I also have Intel Graphics 4000 on my machine, and have tried disabling it and even uninstalled the Intel driver at one point, to no avail.
Can I please get a response to this issue. Thanks
