Forgotten User Password

[holly35]

My brother very clumsily has forgotten his password for get into his user account on his computer
He has a guest account, which he is using but it is preventing him playing games.
Can I reset the password through the BIOS? i went into the settings the other day and thought that I had solved it, but it hadnt!

Any suggestions?

Cheers, Holly x

hmm well I tried the classic log on screen administrator trick, but it asked for a passwork and wouldn't continue without one.
I tried "preventing a forgotten password" disc but it asked to enter the current password, and because the only account that works is a guest account, it wont show the admin account.
I was thinking perhaps if I formatted the pc it would re-enable access to everything. Im sure he doesnt have too many important things on there (he's 11).
When I put it into the settings bios menu, it asked me for a password I believe this is the password I created the other week, although I typed that in and it will not accept it.
Would re formatting work? Or will it not allow this on a guest account?
