I have a Hp pavilion dv6.And after installing the new 326.80 driver from Geforce experience. It prompted me to restart my computer just like usual so I did. After shutting down normally it would not get past the starting windows screen. So I shut it down and I received a message telling me windows could not start properly. I did the recommended thing and started the repair service and it told me that my problem was in fixable according to them. So I tried booting in safe mode and the screen starts to load the core drivers and then just sits there forever. Doing a system restore was my other option. So I went to my most recent restore point (2 days before installing the driver) and it restores everything and says it is successful so I restart as I am prompted to. The computer gets past the windows boot screen and goes black and then sits there. I have tried these options numerous times but to no avail. If anyone has any suggestions ad to how to at least get me to my desktop so I can roll back the driver please let me know.
