I would disconnect the internal HD and with a bootable external or CD/DVD see what happens. Does it boot up cleanly? If so the boot files are corrupted on the HD and you'll need to delete the partition and reformat the HD. If you can't get it to boot the EEPROM where the firmware is loaded on has a problem. If you have access to the correct chip clip and a burner and access to the firmware file image you could try re-burning the firmware. Otherwise you'll need a new EEPROM or exchange out the logic board.
