Thanks for your response.  Subsequent to posting my problem, I searched more through the forum and found comments suggesting that EVGA Precision causes instability problems with PoE.  I disabled EVGA Precision, rebooted, and the crashing ceased.  I think we can mark this problem as solved.
 
 
Welcome to the forums Mdnyc,

The error causing the crash in your example seems to involve NxRay. It may be worth checking other crash logs to see if they give the same cause and checking to see if the crashes occur at the same (gameworld) locations.

If the crashes don't occur predictably then GPU overheating is worth checking for - it can cause a wide variety of similar errors (and PoE is unusually demanding for the graphics it produces). Use MSI Afterburner (or similar software) to track GPU temperature and check the maximum reached. If it hits 80°C or more, then you need to improve cooling.

Hitting power supply limits is another possibility - cheaper PSUs very often cannot handle their supposed maximum loads but the only way to verify that would be to swap yours out with one offering higher capacity.

If, on the other hand, your crashes are predictable (always at the same place, same error reported in output_log) then try using Forceware drivers that are WHQL certified (yours currently aren't) even if it means installing older ones.
