Could you please let us know the driver version you are running? Please go to Device Manger> Display adapters> Intel(R) HD Graphics right click on Properties and then go to Driver, you will be able to see the version installed.
When I wrote my post I was using driver version: 188.8.131.52.4331
I have since updated to the recently published drivers version: 184.108.40.20652
So far I have not experienced the lock-ups as I did before. Thank you!
I am glad to hear that!
If you need further assistance let us know.
