Hi all. I have a old power pc G5 2.0 ghz dual with 2gb ram. It runs OS X 10.5.6. is my first mac, am 16 years old and love my mac, i bought for 600 three months ago, since a month or so all of a sudden it crashes for no reason. while using it it just freezes then if i live it for few minutes all the fans start working a making noise. i changed ram, HDD and restore it 3 times. i went to the apple store and they have no idea, if i want them to make a diagnosis the will charge me 85, so before i do that i would like to get some help from this forum. i did research but no one has this exact problem.

Thanks for your help and time to read this.
 
Apple Menu > About This Mac..., then click "More Info". It will launch System Profiler. Under "Hardware Overview", you should find the model.

You should also be able to confirm this by going to Apple Support, Tech Specs, and enter your serial number (also found in Hardware Overview).

Some of the older dual 2Ghz G5's had some hardware issues, I'm wondering is your one of them?? Those issues varies from a leaking heatsink to faulty second processor socket both of wchich can cause system failure's and random crashes.

Personally I'm not sure how you'd tell which systems are affected, maybe some avid G5 user would be able to shed some light on this??
 
done

thanks, all of you. i have reset the PMU and uptade the firmware, i hope all this work couse i cant tell yet. but if i have another crash i will post it. thanks again.
 
Yes, some of the G5s would shut down for thermal overages.

Looking at the log helps.

But if you have dirty power, it'll cause you all sorts of pain. So if you have turned something on in the house recently like a fan, or switched to eco-bulbs you might be getting line noise.
 
you have a serious hardware problem. Most likely the logic board, 1 or 2 CPUs failed. A freeze with fans running up means the system is locked solid and it doesn't even get temperature sensor info, so it runs the fans at max to cool the system as much as possible.

I had the same issue, after about 1 minute a message to restart displayed in like 20 languages slowly rolled down the screen. Turned out it was a bad processor. Removed it and the system ran on 1 no problem.
