Display Problem: Persistant Yellow Line One Pixel Wide.

This is more irritating than downright harmful. There is a yellow line, that whenever I turn the computer on, even on the booting screen, that displays constantly. I updated Nvidia's bios and the drivers for the video card. Oddly, my laptop has multiple monitors despite me only having one LCD screen.

 

I have never dropped, hit or abused my poor laptop. There is a flourescent light in the room but it's one of those old 70s lightbulbs. I am running an Inspiron 8600 with an Nvidia Go 5200 video card. Is it my LCD or what? And should I just take the laptop to someone for repair?
