Are you switching between your GPU's?
The crashes are caused by a driver for the display from Nvidia.
Please uninstall everything of Nvidia using Display Driver Uninstaller and install new drivers from your manufacturer. Be sure the clean install box is checked and only install the Graphics driver and the PhysX driver.
