Weird Flickering Problem on Laptop Display

Hey everyone,
When I view anything on the screen with a certain colored pattern, that area of my screen flickers. For example, when I visit: http://www.beyond3d.com/index.php The gray/black lines on the left side of the site flicker, but the rest of the site looks normal. Even when I visit advanceflash.com, the dark gray background flickers while the rest of their movie is displayed perfectly.

Recently, I noticed that dragging any new window over a solid dark bacgkround (similar to that of a blank Flash or Fireworks) window causes my system to lag a lot. I don’t recall that ever happening before.

I’m running 1600x1200 on a Radeon Mobility 9000, and I reinstalled the graphics drivers. The computer doesn’t seem to be overheating either.

Anybody have any ideas what is up?

Thanks!
