I can't see anything for your screen shot. I had a similar problem and knew that it could not be possible. If I booted up then shutdown I would get that problem or just in normal use. All I would run is one or two apps. Then I figured it had to be some crap program I installed. The first program I uninstalled was System Works 2002 Pro and it turns out that was the problem, even though I was not running most of theirs services and options in the background. I believe you are having the same problem with whatever applications that are running in the background or as services.
