i have forgot my password and i dont have the disk to my computer

Hello rstine,

After reviewing your post, it sounds like you need to reset the original admin password. I would recommend that you read this article, it may be able to help the issue.

OS X: Changing or resetting an account password (Snow Leopard and earlier) - Apple Support

If your computer doesn't have an optical drive, connect it to a computer that does using Target Disk Mode, or use the Remote Install Mac OS X utility to start up the computer remotely.

Thanks for using Apple Support Communities.

Have a nice day,

Mario
