I have an xp desktop, a couple of days ago I went to use and it is asking for an admin password. I have never had a password on and I can't log in, although I can log into safe mode. I logged in to safe mode this morning and changed the password, but still can't access in reg mode. Does not accept new password. Any help would be appreciated. I don't use this computer much - also have a new laptop, but I do have a lot of old information on this computer.
