Seems to be a crowd solving this with a newer Intel driver: www.reddit.com/.../ 
Hi All, First of all, I would like to say that I am very disappointed with Dell. Last month I ordered the XPS 15-9560. Once I received, after 1 hour of usage a black screen issue appeared and every 10 minutes  the black screen comes and the system hangs. I contacted Dell services and after a long discussion and waste of time, they agreed to replace it with a new laptop. After a long wait and wasted one more week to get new laptop, I got today another. All data setup with personal data etc spend lot time to transfer data second time. I have again problem now laptop freezing 5 to 10 second. When I written email or used work words coming after 10 second. I think best option return back to Dell. Regards, :emotion-39:
