think you may have a corrupted copy of OSX installed

you will need to reinstall from the start up discs

Either that or your Hard Drive is having issues. Try booting with the DVD that came with the machine in the drive and hold C down till it starts. Use the Disk Utility on the DVD and see if it finds any issues.
