Screen turns black then DAZ goes unresponsive and unexpectedly quits after render

I may have done something wrong with my drivers.As the title says [Screen turns black then DAZ goes unresponsive and unexpectedly quits after render],even if the scene is completely new with nothing.
It only happens AFTER render.

I have had a similar black out after rendering a heavy scene, I would suspect it's as the data is tidied up, but DS doesn't quit in those cases that I recall. What are your system specifications?
Windows10 64-bit, 8GB RAM, GeForce 960M
There's no problem until I updated my drivers this morning
That's limited RAM, is it also being used by the GPU (I assume this is a laptop, given the M-version GPU)?
Yes it's laptop. Due to the limited RAM I only render simple scenes, it always goes well.
There must be something wrong with my drivers, I updated to the newest level (430.39),It works but the previous version seems better (better rendering speed), I just can't remember which version it was
