suddenly, an array of vertical bars crawling up the screen.

New problem this week. After my computer warms up, the screen image deteriorates dramatically. An array of vertical bars, like the columns of a greek temple, suddenly appears. The columns seem to "crawl" vertically.

The mouse cursor picks up a sort of shadow, and unnatural sub-cursor that follows it around.

Changed monitors. Same problem appears after a short warm up period. So it isn't the monitor.

Next thought is the graphics card? It is an ATI 9700 Pro, installed in a Dell, circa 2002. It runs a digital output to a Dell LCD screen.

I also have an ati All in Wonder remote controlled TV.

I can clean up the screen by turning on the TV, but not for long. Pretty quickly the TV picture deteriorates.

Is this a graphics card problem? Or is it more likely the motherboard?

Many thanks for your insights.

Hello, thank you for your reply.

It is a standard power supply included by Dell with their Dimension.

Is this maybe something like a 60 Hz hum, bleeding into the image or messing up the synch?

Thank you for your reply.

I traced the problem to the Radeon 9700 pro. I swapped it out with a Radeon card from another Dell here, and after that, the problem did not reccur.
