I recently bought a gigabyte HD7870 OC - installed and used CD for drivers, was working fine.
Yesterday I used the Catalyst uninstall software to remove the drivers (8.9, I think) and install ver. 12.104. After running the program to remove the old drivers Windows restarted and now fails to boot, even in safe mode.
Auto repair does nothing, I have no option of a repair install and no sytem restore point as I was just finishing a fresh install and was making the final tweaks to configs/settings before enabling it.
I can however access my desktop by starting with driver signature enforcement disabled. Searching around other forums I don't appear to be the only one having issues with this tool.
I have tried everything I can think of to fix this to no avail. I'm trying not to have resort to a backup/full reinstall of windows as it's just taken me the better part of this week to get the whole thing up and running installing programs/updates and tweaking settings and such. So much for playing Bioshock this weekend.
