Hey there! I've been having an issue when installing any drivers after 12.8. After a super amount of googling I found someone with a similar issue http://forums.amd.com/game/messageview.cfm?catid=454&threadid=161893&enterthread=y here and you can see a sample image of the issue.
Sapphire Radeon HD 7850 2GB (Driver version 12.8)
Windows 7 Home Premium 64 Bit
ASUS P7P55-LX Motherboard
Intel i5 CPU 760 @ 2.80 GHz
Acer P236H Monitor (Hooked up with a HDMI cable)
I've tried Driver Sweeper and multiple installs with the same results. 12.8 works perfectly, though.
