Weird 2001FP question

[Brainwalter]

The leftmost column of pixels flickers red constantly. Each pixel flickers individually; it looks kind of like static. Only a 1-pixel wide column is affected, although sometimes I see isolated red pixels elsewhere on the screen (this happens rarely and to a small extent).

The isolated pixels and the flickering column are limited to areas of the screen that are black. My desktop is black, but if I interpose a window over the column of flickering pixels, the ones covered stop. I hope I've described the problem clearly.

I got mine a few months ago. I used it for a couple days, and then I left town for about 2 weeks. When I returned, I noticed I had left the monitor turned on. I don't think this probably caused the problem. There was no signal to the monitor so it should have been hibernating or whatever monitors do. I only mention it because it may be relevant, and I don't recall noticing the problem before leaving town.

The DVI connection seems firmly connected.

Anyone have any idea what I'm talking about?
