Thank you for joining the Intel communities.
Try accessing the Intel® HD Graphics Control Panel and press <Ctrl><Alt>F8 on your keyboard to set you graphics to defaults.
If this does not work try the following:
Uninstall the Intel® graphics driver, please see Uninstalling the Intel® Graphics Driver and Intel® Display HDMI/Audio...
Download the latest Intel® driver here: Download Intel® Beta Graphics Driver for Windows® 7/8.1/10* [15.40]
I suggest uninstalling the Nvidia driver as well and reinstalling it, restart your system every time you uninstall the drivers and you can download it from the ASUS website.
After that is done, install the Intel® graphics driver first and then the Nvidia driver.
As well I recommend updating all the drivers from the ASUS website and Windows update.
I hope this can help.
