Am having 1-2 times per week BSOD with same notice (when I can whip out my phone fast enough to capture it):

Stop  code: SYSTEM_SERVICE_EXCEPTION
What failed: igdkmdnd64.sys

This is a relatively new Inspiron 7506 2n1 w/ souped up specs talking to a Dell WD19TB Thunderbolt dock and a pair of Dell S2421HS 1920 x 1080 monitors via display port from the dock. I regularly run the Support Assistant to update anything and everything. 

Pretty Important: I get update notices from Intel about driver updates but have ignored them and only installed updates from Dell, on advice received in this forum.

No notice of failure and no pattern that I've noticed about what I may have been using when this happens. I am a university professor teaching online this semester and have had this happen during a live zoom class but also while running a variety of programs.

There is a lot of info out there about this problem with igdkmd nd 64.sys (missing two characters) but am reluctant to move forward without knowing what exactly I should be doing. There is very little info about this exact .sys file appearing in this message.

Have repeatedly run full diagnostics after this failure but no issue is ever detected.

Any help to cure this will be greatly appreciated.
