Freezes On Start Up


upon startup, when it comes to the log-in window, it's frozen, the mouse doesn't work nor the keyboard. i've tried re-installing osx, but it freezes while checking the drive at 54% complete. this machine has never been on the internet and i'm running os x 10.3.9
Boot from the OS CD, after the Installer window appears, go up to the Installer Menu to Disk Utility. Use that and see if it can Repair the Disk.
