Connect a USB keyboard/mouse, and try booting to the software restore disc. Run disk utility if you were able to boot to the OS disc successfully, both the verify disk permissions and verify disk options. If you cannot boot, its time to have it diagnosed at a service provider. Depending on what the Disk Utility results show, you may need to reload the operating system on the computer.
