I been having problems with 190.xx drivers with my overclock. I would be playing Tmnations or Counter Strike source than my screen will freeze. I switch back to my desktop and it says Nvidia drivers have recovered, normally if the drivers crashed the clocks would revert back to stock speed but they don't. After I uninstalled than reinstalled to 186.24 I never been having any problems yet. Anyone else been getting crashes with 190.xx drivers?
