i mentioned that even when I force shut down, and restart, that even that takes a few times. What I meant by that is that when I restart (after a shut down), it seems to go right back into sleep mode. The monitor never lights up or turns on, and the sleep light is pulsing. AFter a few cycles of force shut down, and re-boot, it finally boots correctly, including the monitor.
One of the most common cause of wake-from-sleep issues are USB peripherals. Try disconnecting everything but the mouse and keyboards as see if the problem persists. If it goes away, add USB gadgets back on at a time until the problems returns.
If you have an Airport card installed an are using the eMac wirelessly, post back. There can be an easily-rectified issue with the Airport software default settings that can create your issue. However, it's much more common on notebook computers that move around a lot.
Try Allan and Dale's suggestions first; if further tricks are needed, try this:
For a Mac OS X with sleep problems (file names and locations are for 10.4.x):
-- trash /Library/Preferences/SystemConfiguration/com.apple.PowerManagement.plist
-- trash /Users/[username]/Library/Preferences/com.apple.systemuiserver.plist
-- reboot while resetting PRAM/NVRAM (see Dale's link)
