Hi,
If you have Win 10 installed, try updating the ATK package and Smart Gesture drivers and see if this resolves the problem.
Be sure to update the ATK package ''first'' before the Smart Gesture drivers.
Here is a link to the [http://ivanrf.com/en/latest-asus-drivers-for-windows-10/|latest Asus Win 10 drivers]
Be aware of the '''Notes:''' near the top of the page in the link, regarding installation of the drivers. Also do not be tempted to update ''all'' the relevant drivers found on this link. It may confuse the issue if you run into problems. Work on one problem at a time. As the saying goes "If it ain't broke don't fix it"
