    Horizontal lines appear on the taskbar.

    There appears to be glitchy horizontal lines on my taskbar that do not go away after a restart. The lines are purple and green and the icons on the taskbar appear to be glitchy as well.

    Hi:

    There is a purple horizontal line at the bottom of the monitor.

    I have upgraded graphics card.

    How to resolve the issue?

    Regards

    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:

    First screenshot

    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?
