Vista Login Welcome Screen - Help!

[TweedleDum]

Ahoy there,
I am trying to help a friend with her laptop. The problem is, if the computer is turned on, it loads to the welcome screen and requests the user account password. After the welcome screen has been visible for a few seconds, a fade affect turns the screen black and the machine restarts, and goes through the whole process again.

Safe mode appears to make no difference.
Resetting to last good known config. doesnt make any difference.

Any help would be appreciated!

Thanks a bunch

Can she try entering the password within that few seconds and seeing if she can get to the desktop, or does she not get chance?

Doesnt get the chance unfortunatley. I thought of that aswell...
