The following is from Mac Help
f you don't remember the password and automatic login is turned off, you can reset the administrator password using the Mac OS X User Install disc.
IMPORTANT: Because a user with the Mac OS X install disc can gain unrestricted access to your computer, you should keep the disc in a safe place.
To reset the administrator password using the Mac OS X disc:
Insert the Mac OS X Install disc and restart the computer.
When you hear the startup tone, hold down the C key until you see the spinning gear.
When the Installer appears, choose Utilities > Reset Password.
Follow the onscreen instructions to change the password.
Quit the Installer and restart your computer while holding down the mouse button to eject the disc.
Be sure to change your login password in Keychain Access to match your new password.
http://docs.info.apple.com/article.html?artnum=107393 is a good place to begin with a mac that won't start up.
If that doesn't help, you might consider starting your own new question; I only say that because more people will read it & you should get more help than adding to this one.
