This problem is kinda weird, When I open some applications such as PowerPoint and for example some pages in Chrome, for a very short moment, red horizontal lines appear on the screen every once in a while. I noticed that this problem recurs when I open any application with a light theme, not Dark
Is this a hardware or software problem? And how can I solve it?

    Hard to tell. Do you see the same lines on an external HDMI connected TV screen?

    No, I don't have a monitor to try on

    How about a friend with a TV set that you can test? Without this test it's very hard to tell whether it's the hardware or software problem with screen, it's video cable to the mainboard, or the GPU itself on the mainboard.

    So all I can suggest at this point is to first try a battery and bios reset as follows

    (1) Shut down Windows normally
    (2) Unplug charger. No LEDs should be lit.
    (3) Insert paper clip into reset pinhole on bottom for about a minute
    (4) Plug charger back in but wait till battery charge LED turns from steady orange to steady blue
    (5) Only after battery charge LED turns steady blue, turn laptop back on and immediately press the F2 key to enter the BIOS menu
    (6) Press F9 in the BIOS menu to load defaults. Press F10 to save defaults and exit the BIOS menu
    (7) Laptop should start Windows login normally.

    If problem persists then we will explore other possible fixes.
