    Laptop screen showing flickering horizontal lines and sometimes white boxes


    I have an hp laptop I bought it last year. It recently started having flickering horizontal lines or white boxes on the screen and it goes to sleep. When you try to switch it Back on it doesn't and when it does the same problem. I recently changed operating system but it still does the same.

    Flickering screen -> grey frozen screen or white/blue frozen screen with white horizontal lines in Windows 10.

    I recently successfully installed Windows 10 and now I have problems with 3 different scenarios:

    1. Normal login into Windows 10 then being on the Internet website or email the screen suddenly becomes flickering that leads to the screen that is partially white on the left side and the rest is blue with multiple horizontal lines through the screen. Have
    to reboot the computer to login again to the windows.

    2. Sometimes flickering screen leads to a grey frozen screen. Have to reboot the computer.

    3. Sometimes flickering screen leads to "Your PC ran into problem..." with automatic restart.

    This is really annoying. Please help!!!!!

    Flickering horizontal lines on screen

    Hi,

    so I was normally using my laptop which I've had for about a year now and all of a sudden the screen froze with all these horizontal stripes. I couldn't do anything so I had to hold the on/off button to shut it down. Once on again it still has these horizontal
    lines. I can still do everything, it's all working and I haven't lost anything but I have these flickering lines that are unbearable, hurts my eyes. If I look closely I can see that in these stripes there's the image of my desktop which is what was displayed
    on the screen when it froze, but it doesn't go away, it's basically like having an extra layer over my screen.

    What's the problem and mostly how do I fix it? It's very strange.

    Laptop screen showing flickering horizontal lines and sometimes white boxes

    win 10 and gtx 970 flickering, black screens, horizontal green lines..

    this is a copy paste (mine ofcourse) and will start a thread with it becouse i find this important..
    ----------------
    i want to share with you my bad experience with win10 and the gtx 970(zotac) ...maybe this can help you



    i bought my gtx970 used from the internet, well almost the whole pc is used but it works pretty well until i installed win 10 pro 64 bit and the new gpu.

    my pc:
    i7 3930k
    mb: intel
    12gb of ram in quad channel
    ssd: intel 535 (win10 original)
    hdd: wd 2tb (win7 cracked)
    LG 4k tv with hdmi2.0 and 4:4:4 compatibility


    b4 i bought the gtx 970 i was using a HD6870 for gaming and it did the job pretty well (win10) but limited to 1080p gaming.. so i bought the 970 and uninstalled the amd drivers then installed the lastest nvidia drivers and here start the nightmare lol


    opened trackmania2 and got black screens, flickering, random horizontal lines (not the whole time) and when exiting the game i got artifacts in the win10 desktop lol white dots everywhere... the majority of the time i can play it with no problems but somethimes i get white dots in the win10 desktop. Yesterday i got green horizontal lines while playing *Sad


    crysis3 just gave me white dots (not always but when i close the game i get white dots everywhere). And noticed something, when the fan goes to 100% it start to show artifacts (not real artifacts just white dots, they dont look like real artifacts)


    CS:GO screen flickering and horizontal lines


    BF3 pretty good game, no problems at all.


    gta4 no problems


    youtube: its weird but i got artifacts when whatching videos


    i also overclocked it to 1450 with the stock voltaje and got 5fps more in bf3 Laptop screen showing flickering horizontal lines and sometimes white boxes :p


    after a week surfing on the internet and sad bcouse i wasnt enjoyning my new pc (i spent something like 1700usd in total)..




    I started to research the problem by my self... found something:


    Went to chroma 4:4:4 to 4:2:0 and problem solved, then went back to 4:4:4 and no problems at all. But then i started to get flickering and horizontal lines in cs:go so i decided to boot my pc from the HDD (win7).


    Long story short: been playing all the games i have and no sing of any problem so...


    i could say that win10 is just too premature to handle 4k content... or even recent gpu's.


    i will stay away from win10 for a while... hope it helps to you!!
