I am running the 12.7 beta drivers and they work well for me. I am running two 6970s in crossfire or single as the situation demands. Some programs won't run with two enabled.
Did you uninstall the Nvidia drivers?
When you uninstalled the ati driver did you shut off the anti-virus before doing so....and did you reboot and shut of the anti-virus again before installing the new driver?
When you uninstalled the drivers did you delete the nvidia and ati folders, then empty the recycle bin?
Did you use Ccleaner to clean the registry when you were done uninstalling the drivers?
I did use Ccleaner to clean the registry and I deleted every ATI folder I could find on my computer as well. I will try reinstalling drivers with anti-virus off. Sometimes it will tell me to update my drivers, saying I am using Version 11.5 even tho 12.5 was installed.
Just wondering if my NB fan dies, will my NB live with just a passive heatsink? And maybe a program that can monitor NB temps.
