osx 10.3.9 will not sleep

[jami1955]

I've got 10.3.9 on a dual 867 G4, 1.5 G of ram, and when I give it the sleep command, the screen shuts down, but the hard drive does not, it keeps going. Anyone have any suggestions?
thanks

Have you checked the Energy Saver settings in System Preferences? Make sure that the option to spin down the hard drive is selected.

Thanks nixgeek, a strange thing. I toggled the spin down disk when possible switch, and tried it. I can hear the hard drive spinning down, but the fans keep going! And they are loud. Any idea?

Got any 3rd party PCI cards in there? Some PCI cards (USB 2.0 PCI cards, etc.) do not support "deep sleep", which involves turning the fans off.

...or perhaps a USB hub or some sort of USB peripherals attached?
