Have you tried downloading the latest drivers directly from Intel?
I have the same problem with my G750JS-DS71.
Upon checking the device manager properties, I noticed that the driver I downloaded from the Asus site was 10.18.10.3960, while the latest being offered by Intel is 15.36.7.64.3960.
So I'll give that a try and see if the problem is resolved.
Best of luck!
