HenryJ, Thank you for posting in the Intel® Communities Support.
We are sorry to hear about this issue and we will be more than glad to assist you with this matter.
In reference to this scenario, it is important to mention that pretty much you already tried all the troubleshooting steps that we recommend for this scenario. Based on the results you provided, the one that states that the system runs no problem when swapped to a GTX 1060, seems to indicate where the source of the problem resides, especially taking into consideration, as you mentioned, that the problem happens most commonly while playing games, which is a task that is handled directly by the graphics card.
In order to rule out a possible hardware problem with the processor, please install and run the Intel® Processor Diagnostics Tool, it does an overall test on the unit and if it passes the test it means it is working properly:

Did you try to test PC and games without using an external graphics card but instead working with the integrated GPU?
In regard to the WHEA error, even though you already try some of the troubleshooting steps, there are additional actions to attempt shown in the following links:

If the problem persists after that, then, we just wanted to confirm a few details about your system:
When did you purchase the Intel® processor?
Did you build the PC?
Was it working fine before without the game crashing and showing the WHEA error event?
If yes, when did the issue start?
Did you make any recent hardware/software changes that might cause this problem?
Does the issue happen with all the games?
Does the problem happen at home or in the work environment?
Please attach the SSU report so we can verify further details about the components in your platform, check all the options in the report including the one that says "3rd party software logs":

Once you get the chance, please let us know the results.
Any questions, please let me know.

Albert R.
