I used to be able to access the Nvidia Control Panel, and I don't know what changed that made it so that I can't access the Nvidia Control Panel.
I did a system restore to an older point, but the problem still persists.
When I try to access the Nvidia control Panel, It says something about not recognizing the Nvidia graphics card on my computer.
Here is a Speccy link because I do not want to list every spec of my laptop.
I run Windows 8 64 bit and use a Intel Graphics card as well as the Nvidia GTX 760m
It seems that the computer does not recognize the Nvidia card.
I did a driver update from the Asus website, because my computer is ASUS n56jr laptop. My games work now, but I still can't access the Nvidia control panel. Rather than having a popup message, I double click on Nvidia control panel under Hardware and Sound in control panel, and nothing happens.
As I said before, this problem hasn't happened before.
