Administrator Password Help !

[gamebuster]

Hi all i recently bought an Apple Mini of fleebay it came with all the cables but no discs. when i boot it up its asking for an administrator password which i dont have and the seller on fleebay is not responding.
Is there any way i can get round this problem.

Thanks GB

All Sorted now found the following and worked a treat.

1. Reboot
2. Hold apple + s down after you hear the chime.
3. When you get text prompt enter in these terminal commands to create a brand new admin account (hitting return after each line):
   
   • mount -uw /
   • rm /var/db/.AppleSetupDone
   • shutdown -h now
   
   
4. After rebooting you should have a brand new admin account. When you login as the new admin you can simply delete the old one and you’re good to go again!

Boot with an OSX install disk - there is a "change password" feature in the menus
