So I am trying to play the diablo 3 beta and it told me to update my graphics driver. I did and about halfway through install, I got BSOD and crash dump. Stuck with a half-installed driver. Windows wouldn't let me update so I used the uninstaller and rebooted and tried installing again. Same thing happened. Please help. Using ATI Radeon HD 5670 PCI on a Windows 7 Home Premium 64-bit system. Trying to update to Catalyst Software Suite 12.1.
