I am running into a problem when I boot my laptop and I get to the vista log on screen. When I submit my credentials either thru typing my user name & password or the fingerprint credentials (doesn't matter which) vista acts as it is logging on, but then just restarts. If I wait a couple of minutes, log on goes thru fine. It is kind of irritating that I have to wait in order to log on. Just wondering what this is due to, since I would not say that my laptop is slow. Is there a fix for this? I am using a valid copy of Vista Enterprise and a HP nc6320 laptop.
