Alright, so my problem is similiar, not sure if its the same as above or not. My taskbar freezes when starting up windows (connected to internet or not). When I hover over it, my cursor just turns into an hourglass as if it was loading. It also wont open Internet Explorer or Taskmanager. It just became this way like overnight some how, I have not installed anything. The taskbar will eventually load after I leave it alone for about 15 minutes... same as if I don't log on. If I leave it at the Logon window for about 15 min and then log on then it runs fine without problem also. Still, very annoying problem. Just today I tried to install SP2 with windows update, but everytime I click on a windows update link a blank explorer pops up as if it was loading and just freezes that IE window. (not sure if that is related to the same problem or not) I have run a PandaScan, used like Spybot and Adaware, and this thing called security task manager to check to see if there was any threatening processes. Nothing that has fixed the problem. I would reformat/reinstall but I don't have a Windows XP CD. And i'm not sure how that would work with having to re-activate my version of windows. Anyways, if anyone has any idea what this could be, please let me know! Thanks.
