Have you tried booting with the [Shift] key held down to boot into safe mode and clear the caches? If not try that, and then restart when you get to the login screen. If it still does not work, disconnect all external peripheral cables and the AC power cord. Open the side door, remove the door and thermal shield. Look inside, down below the memory slots about one inch up along the bottom edge of the main logic board, just in front of the processor intake fans, where you will see the SMU reset switch. It is a round grey or white momentary contact switch set in a square metal "can", much like the PRAM switches in older G3 and G4 desktop systems. Press the SMU switch once, and once only, releasing it immediately. Wait at least ten seconds before closing the system up, re-connecting the external peripheral cables and the AC power cable. Try to start the system from the OS install DVD, and reset the system password. If that doesn't work, check and, if necessary, change the PRAM battery. Try booting with the [Command] + [Option] + [P] +[R] keys held down until you reach the open firmware prompt. Try the usual NVRAM reset commands, press [Enter/Return] key after each command: reset-nvram [Enter] set defaults [Enter] reset-all [Enter] The system should restart. Hold down the [C] key as it boots to boot to the OS install DVD. Try and change the password. If successful, see if you can log in. As someone else suggested, be sure you are using a wired keyboard so the keyboard will be recognized and functional when you reach the Login prompt. If none of the above works, boot from the ASD CD and run all the system tests. Good luck.
