Hello Nick,
The problem of unresponsive/freezing screen with your ASUS device might be due to simple low level errors or driver crashes. A simple reboot of your device can allow the screen functionality to be back to normal. However, if the problem still persists, you might need to do a Windows Advanced Boot to repair your device.
