My Mac OS X 10.5.8 when left idle, the screen turns black and I must push the power button to turn it off and restart it. How do I fix this problem? Thank you!

    Is it possible you have the Display set to go to sleep after a set time....found in System Preferences, in your Dock, under Energy Saver?

    ASC has been down for awhile...reason for delayed response.

    Try things in this SMC reset article.

    Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk for OS 10.6.8 and under. If you are running 10.7 or 10.8 run Disk Repair from Disk Utility on your Recovery System. It shows you how in the link.

    You could have some directory corruption. Let us know what errors Disk Repair reports and if DU was able to repair them. This could just be a start in repairs and you may need a better utility to finish the job.

    Then Repair Permissions.

    No need to report any Permissions errors........we all get them.
