Loops after coming to user screen

I have a problem with booting up. Every time it gets to the user screen either I pick one and then a password screen flashes for about a second then it reboots and continues to do this. If I hit F8 and pick last known good boot it will start fine. Sometimes I get a password screen that says "not authorized" before looping. Any and all suggestions will be appreciated. I have ran spybot S&D, McAfee and they both say the system is clean.

Hi and welcome to the forum..:)

Have you tried running the repair option using the vista install disk? You'll need to set your boot menu to boot from disk and then run the repair function when prompted.

Please post back if this is of no help.

That didn't work either. I may have to reload windows but trying not to.
