I updated my Catalyst driver to 9.12 after it came out. After the update, the computer will only show a black screen with a blinking DOS type thing in the upper left corner. It will not completely wake from hibernation or sleep. I uninstalled 9.12 and installed 9.11 to see if that would help and it did not. Here are the important specs:
AMD Phenom II 705e
4GB Dual channel DDR2 800
ASRock 790GX mobo
HiS Radeon 4670 1GB PCIe, stock clocks
Windows 7 Ultimate x64 retail
