Hi, welcome to justanswer.com! My name is Mike.I am going over your question and I will be with you shortly.
Put the Leopard install disk in and restart holding down the letter C key until you see the Apple logo. Choose your language then you get to the install screen DO NOT INSTALL, you will see at the top of the screen a Utilities menu drop down. Go the Disk Utility, Highlight your hard drive (usually Macintosh HD) and click on Verify Disk on the right. If that is OK and only if that is OK click on Repair Disk Permissions. If Verify Disk is not OK try to Repair. If Repair is successful then Repair Disk Permissions if it is not successful let me know.
OK In that case you have two options: if you have a current backup you can erase the hard drive and reinstall the system then restore from backup, if you do not have a backup you can try third party startup USB drive like Disk Warrior to try and repair the drive which can many times repair a drive that Disk Utility cannot. Let me know.
Other than that your only option is to erase and reinstall with no backup. If you are satisfied, please kindly provide an OK or Above Rating - so I get paid. Also please note we get paid the same no matter how long it takes to solve your issue, so bonuses are GREATLY appreciated.
