My 2nd Generation imac G5 has recently been turning itself off and proving difficult to turn back on. Is it the power supply unit or as i've read the logic board

From Apple Support:

1. Turn off the computer by choosing Shut Down from the Apple menu, or by holding the power button until the computer turns off.

2. Unplug all cables from the computer, including the power cord.

3. Wait 10 seconds.

4. Plug in the power cord while simultaneously pressing and holding the power button on the back of the computer.

5. Let go of the power button.

6. Press the power button once more to start up your iMac.

That's exactly what I would suggest you to do. And if it doesn't work sell it to me REALLY cheap!http://images.macrumors.com/vb/images/icons/icon7.gif

imac g5 shutting itself off

Further to my previous note. i am managing to get it started again after several attempts and it's staying on for a period of 72 hours then it shuts back down again. When i'm away from the machine for an extended period should i put it to sleep. is leaving it on compounding my problem?
