That Mac can not run OS X. Do you know what OS was installed on it?

Try starting it up from a OS 9 (or System 7 or System 8) CD. Start up the computer, insert the CD and immediately hold down the C key.

You can also try using Norton Utilities. I believe version 4.5 or 5.0 will work on that machine.

You need to reset the PRAM... start up holding down cmd-option-P-R and hold those keys until you hear the startup chime three times and then let go of them.

As has been noted, this system was not designed to run Mac OS X and trying to start the system from a Mac OS X disk is going to cause you issues (as you can already see).
