Well well...! just a few minutes ago i got freeze and for the first time when i tried with (crtl+alt+del) to open task manager, did not work! , tried to sign out then got blue screen with memory dump (which i was turned it off already because of ssd lifespan) . after that when windows come up, my GPU was not detected at all! then force to shut it down for couple min. then my GPU is back!
(i wish i didn't turned off the memory dump!)
when i got blue screen which was for first time in this build, did not get pic from it,i just remember was something about POWER_State_Driver....!
for the record: this windows was installed fresh and with all updated original latest drivers.i will enable the memory dump for the next crash and will share!
