This probably means some startup program or service is
somehow broken. Have you recently deleted a spyware, tray
app, or the like, done a virus scan and removed one,
uninstalled something, etc? If so, try regscrub to clean
out any residual commands to load the program or part of
it. Also download xteq and see what loads at boot and
remove any you do not need.
If you notice a specific thing that causes it (starting
IE, logging in, running some specific app, etc) let us
know. If its after the computer is idle, check your screen
saver. Do a full reboot if you have not. all the usual
stuff here, but we dont have much to go on.
