Please share your system info.
You can extract it from Blender in the Help -> Save System Info menu.

In attachment.

The driver version 375.70 you have is more than 2 years old. The latest version for you card is 419.17 as far as I can tell, did you test that one?

Yes of course. It was 419.17 that I originally had.
Rollback to 375.70, made when a problem arose, in search of the most stable driver for my video card model.
The system was installed in early January 2019.
Driver reinstallation was done through the Display Driver Uninstaller.

A small addition.
I tried to disable the support for Cuda on my card in the settings of Blender. System tab, set to None.
It did not help. Anyway, the system crashes.

Also during the tests, I discovered that the same fall occurs with the use of Eevee Ambient Occlusion. Unlike Volumetric, the fall of the system does not occur immediately, but after some time of use in the Render display mode.
The remaining rendering modes - do not cause failures.
Render Cycles - also works without failures in all available modes.

I admit that this is due to the presence in the system of the second (integrated) card - intel HD3000, which does not support the minimum acceptable version of OpenGL.

Conducted more tests, changing parameters.
It was possible to start the work Volumetric.

By default, Tile Size = 8px is set in the Volumetric parameters. If before activation of this item is set to 16px, Volumetric runs without errors. And working!!! Allows me in the Render display mode to twist the scene in the viewport, conducts a full-fledged final render, etc. And all this is stable and without errors.
Tried even on difficult scenes.
When this parameter changes to any other (8, 4, or 2), the video card is instantly turned off and the system crashes.

Ambient Occlusion, still not stable.
Allows you to activate this item. But when approaching the object (at a close distance) - the same way - instantly shutting down the video card and crashing the system.
Tried to change all the parameters of Ambient Occlusion - but did not find one that would allow to approach the object in the viewport.
