EDIT:
tested now long time (days) without the driver, my system is perfect again.
tried the driver today , and wham problems returned.

lol
driver is not good for sure on my build 14393
i am...

if drivers are not working fine after windows boot, then i first suspect the fastboot feature in BIOS and windows 10.
(energy settings , choose what power buttons do page) , it is a checkbox you can...

SetPoint6.67.83_64 i think this one gives issues on my windows 10 Home x64.
i get blinking screen since lately with latest Nvidia WDDM 2.1 drivers , all of them.
so i doubt Nvidia is to blame.
