Hello I recently purchased a refurbished Apple Mac G5 Desktop, Ive had it since this past June, and it worked fine up till today. The Mac will startup and works fine but then all of a sudden after about 6 to 10 min. It just shuts down and restarts. Ive searched online but all I can find is it maybe due to a heat problem, the fans are not cooling the unit, and that this is causeing the computer to overheat, or I read that it could be the Internal power supply, thats bad. Or it could be that I need to replace the internal battery, and reset the PRAM.
Hello, We are a small press company and we are getting 10 new iMacs for the office. I'd like to turn one of our old mac into a server, which is a PowerMac G5 Mono 1,6 GHz with 1,5 Gb of RAM.
I ran tech tool and scanned the internal hardrives and it states all is ok as far as that goes. I purchased this used mac because my other intel G4 Mac had a Bad harddrive and I could not afford a new Mac Pro, I use Adobe Photoshop, and Adobe Illustrator all the time.
Anyway if anyone has had a problem like this and found out how to fix if you can tell me That would be great Thanks. Hello Again today I tried useing a standard Mac that came with my other mac, and so far it has not shut down, I plugged the mac directly into the wall outlet instead of the Power strip I had been useing, I read that if its a cheap power strip that can cause sags in the current enough to shut off the mac, also this used mac came with a non original black power cord and not the original Mac white power cord they always come with. I went into the utility console and I did not see any logs of PMU Forced Shutdowns or any thermal runaway errors 122. What it did say is this I dont understand any of this code but well maybe someone here does so here is what it states. Shutdown NOW! Shutting down Q master process.

Iwrok service Line Stopping HP IO maonitro. Starting a new daemon application shutdown now! I ran disk utility and scaned the harddrive for any errors and it could find nothing said everything is fine.
Well if anyone can tell me what this console logs mean or if they are any thing that are realated to my Mac shutdowns. The next thing I was going to do if the plug switch did not do anything is repalce the internal Pram clock battery its the 3.6v Lithium type alot easier to access than my other Mac pro where it has a watch batter type. I think this may have solved my problem. Well have to wait and see Thanks for all that responded to my problem. With my luck I probaby will be back.
Well Hello Everyone, Im back again Thought I had fixed the shutdown problem but after 20 minutes it shutdown again, and now it wont even turn on to get access to anything. Im thinking maybe if I unplug it for a day and try again at least I wiil be able to get some important files copied off the harddrive. I was going to try and adjust the Energy Saver to Reduced setting I read somewhere online that this helped others that had the same kind of problems with shutdowns, guess I will have to order a PRAM battery also and see if that does anything. Since its a used Mac thier is no warranty so and the Ebay guy I purchased this from seems to have closed up his EBAY shop how nice. Well I learned my lesson not to buy a used Mac off of EBAY. I wish I had one of those APPLE Store Repair bars to bad for me no locations are close to me, last time I had to get my other Mac repaired I had to take it to Best Buy, what a nightmare, they fixed it but took them forever and they did not do a great job for what I paid for the job. Did anyone take a look at what I posted about what the Mac's console logs stated.

Shutdown NOW! Shutting down Q master process iwork service line stopping IO Monitor Starting new daemon application shutdown NOW! The logs say this everytime it shuts down in the log. When this happens I had Adobe Photoshop CS2 opened and I was working on a file. This is what I was working on when the Mac shuts down without warning.
This Mac is running Apple Mac OSX Leapord and Apple OSX Tiger. The Apple Mac Pro G5 is 2.5 Ghz DP/512MB 500/160GB/SD/R9600XT/56k/PCI-X I guess this will probably be the power supply will have to be replaced. Don't know what else to check or do to solve this problem. If anyone knows what the console logs mean if they can let me know Thanks.
This video demonstrates how to install additional memory into a Power Mac G5 system. It is G5,1.8 single processor machine.Start by lifting up the latch on the back for the front door. Remove the front door. Remove the plastic air blocker system and remove the main fan assembly just like is told.
Going to install four 1GB memory, these are OWC 1GB chips. It's very simple to install. Have to install memory in matched pairs. There is existing 512MB memory in the form of two 256MB chips in this machine. First start at the last lower bank, so that they go in only one direction. Press the memory in and lock them very tight.
Matched pairs means you need to go from the inside to the outside of the exact same size memory chips. Place the other chips in the same way. So 4.5GB of memory in this machine now in four slots. Installation of everything put in back of everything is very simple, put the fan assembly back in, air blocker back in place and then place the front door back on and latch it back in place. That's all it takes to install a memory to Power Mac G5 system.
