I posted a more detailed report in the Dell community: Re: Dell Precision M6700 goes blank - Dell Community
I have Windows 10 installed with the latest updates. The April update seems to be causing a BSOD on a regular basis.
The Dell support assist diagnostic tool reports that the DirectX driver is failing.
I have the latest Radeon Pro software installed for the Dell M6700 workstation.
I cannot restore to an earlier point. I could restore a backup; but that may not solve the problem.
I've tried everything but replace the DirectX driver - since that seems impossible.
I'm trying to find a solution that will work.
