IMac G5  shuts down unexpectedly

November 30Hits:0

Hi friends at Apple Discussions,
This week my iMac has shut down by itself unexpectedly about once a day. Immediately after it shuts down it will not start up, although after a 10 minute wait or so, it will start up and run just fine. Nothing had been changed, hardware or software, recently that should have caused this.
It is a Rev A machine. Serial number is QP507XXXX. Within the first 6 months of ownership, she had a power supply failure that was repaired under warranty by an Apple Retailer. Everything has been great since then.
I understand that this might be another Rev A hardware failure issue and I believe I am still inside the three year repair window. However, I also understand that there are often preliminary steps to take before jumping to that conclusion.
Any advice as to what action should be taken next? I appreciate your expertise.
James
iMac G5 1.8 GHz 20" Rev A 768 MB RAM (Crucial).   Mac OS X (10.3.9)   iBook G4 12"

In previous posts I did not mention that I am not under AppleCare. The tech was willing to help but suggested that I might try isolating/replicating the problem on my own. Otherwise, if I take it in and they find it is a software issue, not the hardware issue, I get charged.
His suggestion: Try an archive and install for a couple of days, see if problem still occurs. That will determine if it is a hardware or software problem. Actually, I believe I'll do a clean install instead for a couple of days, as my entire hard drive is cloned & bootable on my external LaCie drive. This is an inconvenience and steals my time, but its easy enough to do, I guess.
So I'll do it, but the question lingering in the back of my mind is...is this actually necessary? Does software shut a machine down randomly and prevent it from booting up again for the duration of some unknown 'cooldown' period? Besides, the only software change I have made relativly recently was installing Camino I am highly skeptical that its a software issue. But because I am not an expert, I will follow the suggestions.
Any comments on this?
