    Thank you so much for you input fire sine.




    Before my g5 froze i was using logic pro and i was monitoring the cpu usage. When i restarted my comp i started logic again and when i tried to monitor my cpu usage the program only showed as one processor. Later i looked in about this mac and it said "number of cpus 1"

    did you ever figure out what was up with it only registering one processor?  I recently took mine apart because it stopped working and now it is only saying there is one in it.

    Same here, shows only one of the supposed two processors. Booted from different HDD and shows same. Activity monitor shows one as well. WTF!!!

If only one of the processors where recognized, the machine wouldnt boot. How are you getting that information? And where is it reporting it?


keep me posted.

My G5 Mac takes a long to start up and the the fans go wild. It's real slow. I ran a diagnostic check and everything passed. I have 80 GB left of hard drive space. Some programs are not working either.


This is a common issue for G5s. The quickest solution is to open up the computer to see how much dust there is built up inside of the case. If the case has a lot of dust by the fan vent, then it cannot properly get rid of the heat that builds up from processing. Try cleaning that out.

If the computer continues to run hot, there may be some much more major issues, including ram, processor, or hard drive. Ram and hard drive issues are relatively cheap to fix, you can purchase new ram dimms or hard drives on amazon.com or crucial.com. Processors are much harder to replace and it's likely that it would be easier to purchase a new computer, rather than a new processor.

Start with the dust issue, then go from there.

Good luck!

It sounds as if it could be a thermal issue.
Open the side and clean out the dust from inside the Mac.(Use a clean 1" paint brush)
Take the main processor fans out and clean the heat sinks for the processors.
If you are still having the same issue, then your only option is professional help.

Hello, I have an X800XT Mac Edition graphics card with a G5 2.0 dual processor and the problem I'm having is that when I boot up my G5, it goes through the spinning weel process, but when it's finished and...


I am going to recommend a hardware approach first and then a software approach, to this issue, in order to assist you. At the end of these procedures, is a general support link from Apple for additional support for no picture in your iMac G5 display

I am seeing more of such display issues like this, and more often than not, if the problem does not have to do with the firmware, it may be a damaged or corrupted file which can hinder the iMac G5 from normal start up functionality.
--------------------------------------------------------------------------------
PMU Reset (try this first)

The PMU (Power Management Unit) is a micro controller chip on the logic board that controls all power functions for your Mac.

• Shut down the computer.
• Unplug the computer's power cord.
• Press and hold the power button for 20 seconds.
• Release the power button.
• Attach the computers power cable.
• Press the power button to turn on the computer.
* Boot to your desktop.

This procedure may help but if it does not, follow the procedure below

--------------------------------------------------------------------------------
-SAFE BOOT MODE-
• Reboot your Mac
• Upon restarting your Mac, press the Shift key.
• Hold the Shift key until you see a White Screen with Gray Apple icon and eventually a spinning gear.
• When you see the Spinning gear, release the Shift key.
• Allow the Mac to continue booting up. Also this may take a little while

(NOTE: this may take anywhere from 5 to 15 minutes to load to the Safe mode screen depending on the performance of your Mac, but if it exceeds this time, shutdown your Mac and try just once more. It may have just frozen up the first time around for you.)

• You are going to enter the Safe Mode (which looks like your main desktop environment - the only difference is certain startup items are disabled.)

• Once within the Desktop in Safe Mode
• From the Finder Menu, click Go> Go to Folder
• Type in this line: /System/Library/StartupItems
• This path, is going to take you to the System Library folder which has all of your Mac OS X Startupitems.
• Remove all of those folders to the Trash.

*Reboot your Mac normally and see if you can access your normal User desktop environment.

One of these two procedures should help resolve the blank display issue you are experiencing,

PowerMac G5 with dual 2.7 processors powers on but no video


There are seven diagnostic LEDs near the memory banks of this model: six in a tight line between the edge of the logic board and DIMM bank 1, and the seventh just underneath DIMM bank 1 and slightly more inboard. Please tell me which of these LEDs are on and I will tell you what they mean.

Random Crashing only one processor showing


Well, I can give you free advice, but I can't give you a free solution. The symptoms are pretty conclusive that you have a bad processor that needs to be replaced. It's theoretically possible that your processor may have just gotten loosened, but highly improbable, as there are eight hex-head bolts involved. Sorry to have to give you the bad news.

I have a G5 Mac with a Power PC Dual Processor. When my computer seems to be doing too much it goes to sleep mode. At first I thought it was a over heating issue and then I thought it was a power issue...


check the setting of the G5, you might have it going into sleep more sooner than expected.

also g5 do tend to heat up, check for burned capacitors, also the fans has to be running at a certain speed, the computer will tell you if it in sleep mode.

click on apple logo / system preferences and display

it should be there
