I recently purchased a dell pc, with windows xp as the os. the login screen displays the name helen (who is the previous owner) when i came to put it on the internet it said i needed to be an administrator, going into user accounts there is only 1 account and that is helens, you do not have the option to add an account or anything. booting up in safe mode also only allows you to log in as helen. If you go into computer management in users ect there is another user listed who is an administrtor and also the administrator account, but i am unable to gain access to either of these accounts, does anybody know what else i can try as i have never had this problem before.
many thanks,
John
