Blue/yellow vertical stripes

[wizard04b]

Lately my screen has had about 1-inch wide vertical stripes in blue or
yellow, depending on the background (blue on black, yellow on white).
It changes when windows are moved/opened/minimized, video is played,
or sometimes when the mouse moves. Any ideas what's causing it or how
to fix it? Here's a screenshot http://i276.photobucket.com/albums/kk1/wizard04/verticalstripses.jpg

Check your card's fan for function and dust buildup. Possible memory module
getting flaky as well.
