After I sign into windows I have a 25-35 second delay until I get to the desktop. The computer seems to just sit there not reading from the HD very much during that time. It never used to do this it always was almost instantaneous. Any idea what is causing this? I have tried to get everything cleared off my startup list, pulled disks out of the drives and unplugged my external HD. Still takes forever. I have windows xp on a E6550. How can I get rid of the logon screen so it goes straight to desktop?
