In a nutshell, do a search for "g5 dual liquid-cooled leak" or similar. You will learn that almost ALL of the G5 dual models produced suffered liquid-cooled leaks. This leak of a radiator-type fluid toxic would, in turn, fry the mother board. Leading up to this would be inexplicable behavior including what seemed like software issues, locking up and, you guessed it, screaming fans.
There are a total of 6 fans in these models, so when the motherboard was glitching and running them all, it does sound like a jet! Anyone experiencing this issue even now This was a massive problem involving a multitude of macs; one which apple successfully "handled" on a case-by-case basis, thereby avoiding a massive recall.
Um, actually, the very first reply in this thread mentions the possibility of a liquid cooling system leak. Yes, I did note they did that on at least one other thread. And funny thing is, I looked up Apple's current and expired extended repair programs, and don't find anything for the PowerMac G5. Seems to me that the problem probably wasn't as widespread as nikon would like to think it was. You'd think a leaking liquid cooling unit would certainly qualify. And those system have to be nearing the Vintage stage by now, if they haven't already passed beyond the veil, so the odds of getting them fixed today is slim to none.

I'm going to try it again first thing in the morning. The inside of the computer is extremely dusty and dirty and I need to clean it, I'm just afraid of bumping something or disconnecting something important. I haven't noticed a difference if the computer is cool or hot but if I let it sit for about a week or so without turning it on, I seem to get one decent boot out of it where I can access the desktop.
I'm going to read all the links you posted and get back to you once I've tried what you've suggested. Thanks again!
Unable to boot past apple logo
I've seen you help a lot of people on here so I've got hope you can help me figure this out!! Mar 23, AM. It may also be intermittent solder joints on an IC but I would try everything else before concluding that I have to play with either of these. Hi Neville, thanks for your suggestions.
I can't get the computer to boot in safe boot mode. I tried a pmu reset but no luck. The computer won't boot from disks or from the screen where you hold down option while its booting Mar 23, PM. BD, I've read through the links you sent a couple times but not sure exactly how to do the hair dryer trick. I must've missed something. Am I pointing it close to the memory sticks for about four minutes? Will this damage anything getting that hot? Ok I tried cleaning it. I also took out all of the memory and ran a hair dryer directly on the ram slots for about five minutes.
I don't know if it was hot enough. I put all the memory back in and restarted I ran another extended hardware test after this, it took about 3 hours but everything passed again. When restarted and attempted a safe boot, I got the pinwheel going in a circle for a bit but then it froze up again!
