Vertical line on photos?

[quiksilver]

I just discovered that some of my photos has a vertical line about a third from the left.
First I thought it's the lens, but my other lens also makes this funny line.

The line is about 3or4 pixels wide, running from the top to the bottom.

It's only visible on photos that I have used the lens to zoom.
If I use the minimum zoom (14mm on the one lens and 55mm on the other) then I don't see the line, but as soon as I zoom it becomes visible.

It's always at the same place (about a third from the left)
What I mean is it doesn't move according to the zoom.

Has anyone ever seen this before?

PS. sorry I don't have a photo here to upload. will bring one tomorrow.
PPS. I have a Olympus E400. Olympus 14-45 and a Sigma 55-200

(I was in a hurry this morning, so I just grabbed the first photo I could.)

The line is exactly a fourth from the left. Just on the left of the bench.
You don't see it so clearly on this one, but if you zoom on the photo it's much more visible.

I think it's like a dead pixel on the sensor, but a whole line of dead pixels.

Why don't I see it when I'm not zoomed all the way out with the lens?

I really cant think that u will get a dead row of pixels..... maybe put the lens cap on or take the lens of and take foto of black and see if it still shows..

also for 100iso there is still noise on the foto weird
