    After KB4481031 I've been experiencing a strange occurrence. Whenever I go out I usually lock my PC, "I know, kind of useless," but have been doing it for years.

    Anyway for the past month or so when I wake up the screen to put in my pin, the screen flashes off and on at about once every second. At first I thought it was a video driver so updated to the latest one and it stopped for a bit. Than it returned so I checked and got a newer update. Again it worked for a bit and than started again. swapped out monitors and still does it. If I do get into windows it performs normally and never flickers.

    Has anyone had any issues like this since KB4481031 update. I doubt the update is the cause but who knows? ?

    TIA

    Not heard of those problems after that update. But I have seen that problem several times before. It typically indicates a failing monitor (you eliminated that by swapping monitors), a failing card, or a failing PSU.
