Sometimes it gives me pop-up message (NVIDIA windows kernel mode driver stopped responding and has successfully recovered), and some times not.
Then I have to restart my computer. Because I cannot click on anything and display is in lower resolution with some green lines.
I have tried to roll back driver, to uninstal it even with some tool http://www.wagnardmobile.com/DDU/downloads.html
I am using:
Driver 340.52, NVidia GeForce 8600M GS
Windows 7 ultimate
Any ideas?
