The iMac is now working normally, but I'd like to know if it is on the edge of permanent failure.
This is the 20", 2.0GHz Intel Core 2 Duo (Mid 2007) machine, the first "aluminum" model, with original hardware, and running Snow Leopard OS X 10.6.4. In the latter part of Dec 14, my wife said that her iMac "would not start up" when pressing the start up button. There was no bong and no activity on the screen. When I checked it on the morning of Dec 15, it would not start up. In a room where the temperature is 63° F/14°C, I found the entire unit to be unusually warm. Facing the screen and reaching around the back, the warmest area was in the upper left. With a stethoscope, I verified that fans and hard drive were not running. Turning off the power and on again at the UPS several times produced no change. Turned off the UPS power for about five hours. With the iMac now cold in the late afternoon, it did a normal startup. Checking the Console Logs for both the Admin and the User accounts, I see nothing to show why the iMac was warm but not running. Both "All Messages" logs show a shutdown by user about 8:15 PM on Dec 13, and then a startup about 7:48 AM and shutdown by user about 2 1/2 minutes later on Dec 14. These logs show nothing until I started it up after allowing it to cool down on Dec 15. Is there such a thing as a partial startup with no bong from not pressing the button hard enough? Can the machine shut down only partially from the Apple Menu command? Should I look at other logs in Console? I have excerpts of both logs, going from the shutdown on the 13th to the startup on the 15th, in a 37 KB folder, ready to send if anybody would like to look at them.
