iMac G5 powers down unexpectedley

If I leave my iMac unattended for somewhere between 2-3 hours, it will power down or crash.

The subject says it all. If I leave my iMac unattended for somewhere between 2-3 hours, it will power down or crash. I'm not sure which, since I'm never there to see it happen. There is nothing in the logs to indicate the reason for the shutdown or anything suggesting a crash. I have no Energy Saver setting that tells it to power down, nor are there any schedules set. So I don't know what I should do. Any advice aside from sitting next to it w/o touching anythin for 2-3 hours? TIA

Of course, people writing learn to not put essential information not in the body text into the subject or title.

I had what looks to be a similar problem a few weeks ago, also with an iMac G5. The solution turned out to be to replace the power supply, but there are other things to try before that.

Here's a link to the thread I started here about the problem:

There is a recall on some iMac G5 models, so check to see whether yours is one:
