  1. Dotted horizontal line appears/flashes across my screen


    A dotted line flashes across my screen every 2 seconds, at the bottom of my screen, a little over the taskbar.

    The part of the screen under it also kind of jiggles, it appears during startup as well, the first time this happened, it went away by itself after a while, but this time it's not getting away,


    I tried lowering the resolution, and the line still appears across the whole screen even though I put the display at 4:3 aspect ratio.

    It still appears at the same place after I move the taskbar too.


    I have done an sfc scan, update my graphics drivers.


    here's a video for better understanding,

  2. Black horizontal lines appearing across laptop screen

    Took delivery of a brand new laptop yesterday with the following specs:

    Unpacked it, started using it, only to find black horizontal lines appearing across the screen sporadically. I updated all drivers, downloaded and installed all Windows updates but to no avail. Screenshots:

    Third screenshot

    Some points to note:

    • I had the laptop connected to the TV screen and the lines appeared on
      the TV as well, thus suggesting it's not a screen issue.
    • Because it's a sporadic and somewhat rare event, I can't say whether
      the lines appear during a particular operation/screen or
      anytime/anywhere.

    I've done a bit of poking around on the net and found that usually the culprit is the graphics card, but not sure. Any suggestions?

  3. I have the horizontal lines of dots appeared on the screen of my laptop


    Dotted horizontal line appears/flashes across my screen [​IMG]


    Hello. Maybe, I have a problem that is not connect with the Windows system but I still would like to ask. So I have my Sony Vaio laptop, I bought it in 2011 or 2012. It run by the Windows 10. About two or three months ago, a thin
    horizontal line of the dots appeared on the screen of my laptop. She reaches across the screen. Four days ago, a second line appeared, too. It’s lower and thinner, and the first line became thicker at the same time (see the pic of my screen). Why did these
    lines appear? I have three guesses. 1. The problem is in the matrix. She wore out. It must be changed. 2. The contacts of the wire that connects matrix with the laptop, those has moved away. I think I can fix it myself. 3. The problem is in the video card.
    I wanted to update it, but my Windows system told me that my video card “has a newest updats” . Maybe, I need to remove the video card and install it again?

    I find that the problem is in the point 2.
