When starting up Windows/XP with any user in the system brings up the user page but hangs. The disk is running something. The internet modem is always disabled. I bring up the task manager and I am in idle 99% with no visible processes running. I select shut down and get two messages. The first is ccSvcHst running and it won't close, so I end it. The second in exployer.exe and I also have to force it to end. Rebot and everything is ok that day.
