Microsoft Windows 11

Yesterday I noticed one thick green line at the very bottom of the taskbar on the laptop screen, today I noticed that the line color is become blue and little wider than yesterday. Now I am very much concerned about that line and I am afraid the line may cover the whole screen. 

I have updated the drivers, the graphics but when it comes to update the BIOS, the hp driver updated website does not contain any update for BIOS for windows 11.

 

Please help me to fix it with possible solutions.blue line at the bottom of the taskbarblue line at the bottom of the taskbarBlue line at the bottom of the screenBlue line at the bottom of the screen
