screen problem

A thin vertical line has suddenly appeared three quarters of the way across the screen of my Mac on the right hand side. How can I get rid of it?

Try techtools pro, in the tools section they's a video test (Monitor calibration and isight verification) it should tell you if you have any dead pixels, it test's the video card also.

It has a lot of other helpful tools to help you keep your computer running healthy.

I have the same proble. It is like a faint dotted line. I have mac snow leopard. Have you fixed this yet? and how? I don't have tech tools.
