Im using Asus notebook K43SD with switchable graphics of Intel HD Graphics and Nvidia Geforce 610M. The thing is, I cant use Intel hd graphics driver, after installing and reboot, the driver crashes. It says that Intel HD Graphics driver is not responding and has succesfuly recovered. I have tried every version of the driver and even installed the driver downloaded from asus website but still no luck. And now I'm left with no display driver. I need help.
