hp presario v3000 windows locked

[TJ2879]

Over a year ago I bought this computer from a gentleman on Craig's list. I never set a password on it. My niece asked too borrow it for a paper due for school and set a password on windows and can't remember it. She set an administrator password. I have tried too rest it bt uhave been unsuccessful. Any suggestions appreciated. Thanks.
