Fresh Win7 instillation on the SSD, installed the latest Amd Beta drivers, everything was fine. Today I check the AMD website and see that there's a new version of the 12.11 beta driver. Installed and didn't like the performance in Hitman.
So I uninstalled, Ran driver sweeper before I reinstalled the previous beta 12.11 drivers I had from before.
Rebooted to install the drivers...windows 7 reaches up to the welcome screen and then crashes.
I am in safe mode now(only way i get a successful boot) but the drivers won't install in this mode.

I really Do not want to have to reinstall Windows 7 again. Can someone please Help?

Other system specs if necessary include a 500gb sata 2 drive, i5 2500k cpu, 8gb gskill 1333mhz ram

Thanks in Advance
