Insert the Tiger installation disc. Restart the computer while holding down the C key. This will boot the computer from the installation disc rather than the hard disc. If it does not boot from the installation disc you will need to take the computer to a repair shop to be checked. If the computer starts up from the installation disc check the hard disc with Disk Utility. (I think there is a Utilities/Tools menu from the Desktop). If the hard disc check reveals some problems Disk Utility will attempt to fix them and you can then try restarting from the hard disc normally. If there are no problems (or it still refuses to start up after fixing the hard disc) then you will need to reinstall Tiger. Choosing the Archive and Install (See links below) option will preserve all your stuff but ideally you would have a back up copy of your hard disc on an external disc.
