endless logon messages - 'logging off', ' saving settings', ' loading settings'

This is a fairly straight-forward computer - Windows XP Pro - used for family email, internet access, digital photos, some music, etc.  This machine is set up as a single user box - a single account, automatic logon, etc.  After no significant events, the machine is now unable to boot all the way.  What follows is the sequence of events:
  - Power on
  - Normal BIOS messages
  - Windows logo
  - Wallpaper appears normally
  - Now things get interesting with the following messages repeated endlessly
    - 'Logging off'
    - 'Saving your settings'
    - 'Load your personal settings'
  - At this point the only option is to power off the machine.  CTRL-ALT-DEL has no effect.  This box does not have a reset button.
  - Safe mode has no effect on either.

My thoughts at this point are that this is a corrupted user profile.

I have a accessible complete backup from a few weeks ago (Powerquest Drive Image).  I have created a bootable CD for maintenance duties (Bart PE) wioth access to the hard drive.

I have saved the current NTUSER.DAT and restored the one from the backup with no change.

So where do I go from here?

I could do a complete restore from the backup - this seems like overkill as well a losing a bunch of stuff that has been done in the meantime.

A partial restore is a possibility, but I am at a loss as to what files/directories may be candidates.

System Restore would probably work, but I see no way to get to a point where I can invoke it.

What happens if I simply delete the current NTUSER?

Thanks,
Richard

Hi Richard,

Press and hold the SHIFT key at startup (just before the Welcome Screen is displayed) in order to skip the auto-logon. Once you see the Welcome Screen, press CTRL+ALT+DEL twice and login as built-in Administrator.

If you're unable to login as Administrator (or as any other user), see section "Logon - Logoff loop, also caused by BlazeFind" here : http://www.winxptutor.com/wsaremove.htm

BTW, NTUSER.DAT applies to that particular user profile. First, let's determine if the problem is seen globally.

Bingo!  I had already tried the Shift key thing - that machione simply has a single user.  Probably should figure out how to have multiple users as well as a straight through logon, though it probably would not have helped in this case.  Anyway, the BlazeFind fix did the trick.

Glad that helped, RichardStetson. And thanks to Lee for the quick turnaround :-)
