how to remove yellow vertical line on the left hand side of my computer windows 10

 

[psoohoo]

a solid line most likely is a failure on the LCD panel.
Does it occur before Windows loads or only on the desktop

If that yellow line is there from the moment the computer starts up until you shut it down, then you can't remove it without replacing the display. It will get bigger over time.
