Windows 10: A horizontal red line flickers at the bottom

Just as the title says there is a horizontal red line that keeps flashing at the bottom of the screen on where the taskbar is located. This started when I was playing a game, when all of a sudden, the frame rate started to drop, and then this red flickering line appeared. I exited the game and restarted the PC and then shut it down once I saw the problem persist. At first, I thought this was due to my laptop overheating and that it would go away. However, even after everything returns to normal, the line still flickers at the bottom. Starting up the computer, everything feels ok at first, but

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.

 

Lenovo 14s display - unreadable with horizontal and vertical lines.

Today my Lenovo 14s screen is now showing all horizontal and vertical lines, and is absolutely unreadable. Even the red Lenovo boot screen is all horizontal lines, and unreadable. Suggestions. By the way, the warranty expired on October 31, 2023, like just ten days ago. *Banghead Not that it really matters, but Win 10 64 2H22.
