Derek,

Is this a G5 iMac or an intel iMac? If so there is a way to reset the  
system management unit.
(See full artical at http://docs.info.apple.com/article.html? 
artnum=301733)

Turn off the computer by choosing Shut Down from the Apple menu, or  
by holding the power button until the computer turns off.
Unplug all cables from the computer, including the power cord.
Wait 10 seconds.
Plug in the power cord while simultaneously pressing and holding the  
power button on the back of the computer.
Let go of the power button.
Press the power button once more to start up your iMac.

Many of the earlier iMac G5s had defective power supplies. When they  
fail they often display exactly the symptoms you describe. I've had  
to replace maybe 2/3 of the iMac G5 power supplies in my labs.  
Fortunately they've all been covered by warranty or AppleCare. If the  
process above doesn't get you going, contact the dealer and have them  
check it.
