1- The machine freezes for a split second every few minutes. When audio is playing at the same time, it also makes a buzzing noise through the speakers when it freezes/stutters for the split second. 

2- When pushing the machine hard (doing rendering work), it freezes/stutters more often, to the point that it sounds like a popping/crackling noise coming from the speakers. 

 

Run LatencyMon. Go to the Drivers tab. Sort it by "highest execution". After you experience one of these stutters, see which one is at the top of the list. (All drivers should finish their work in less than 1ms, so ideally you wouldn't see anything over 1ms. However, anything over a low single digit milliseconds is especially bad and can lead to audio and system stutters.)

 

Does anyone have one of these systems who is not experiencing problems with it? This sounds even worse than what I was experiencing with the Precision 7770. (Combined issues from Dell, Intel, NVIDIA, and Microsoft on that system is what forced me to rethink what ecosystem I am even using...)

both 7770 and the later 7780 were before they decided in all their wisdom to stack both dGpu and CPU on top of each other for the perfect "easy bake oven" effect.

Thank you very much for the advice. I ran LatencyMon, can you make sense of the attached results?
