Does this do it in Safe Mode ? I would run msconfig and try to disable some of the unnecessary stuff from running at boot up. I would definatley disable your Norton and anything else the loads into the system tray. I would disable everything that you can and see if it still does it.
If it does still do it, then reload the OS is probably the best idea (or try a system restore if you have one previous to when you noticed the issue).
If it doesn't do it then re-introduce items systematically until you have identified the culprit.
