Thread: G5 iMac a weird problem
07-19-2005, 02:49 PM #1G5 iMac a weird problem
My G5 iMac has started playing up recently.
The fans are making noise that is louder than a G3 iMac and they sound as if they would when using about half the processor power.
I don't think it's the same problem that everyone is talking about with the mid plane assembly (but i could be wrong).
It's almost as if the computer doesn't realise that it's not processing anything and insists on having the fans on.
I have tried repairing permissions, Mac Janitor, Tech Tool Pro and Internet Cleanup and nothing seems to work.
The weird thing is that sometimes for 5 minutes or so it will be completely silent, but then the fans start.
Any ideas ?
Thanks in advance

I have an iMac G5 and the same thing happens to me, especially when fast-scrolling through a graphic intensive website. What apps are you running when this happens?

Fire up activity monitor (/applications/utilities). Go to the "window" menu item and check CPU usage, and Activity monitor. A/v shows you what apps are running.

Well I took a look in Activity Monitor and I can't see anything that would cause it to do this.
At present just running Safari & Activity Monitor.
It also says Applespell, Button Manager, iCal alarm scheduler, Finder, SystemUIServer, Dock, pbs, login window, ATSServer & WindowServer
under "My Processes"
In the lower portion of the window it says
% User 5.00
% System 3.00
% Nice 0.00
% Idle 95.00
It's all chinese to me !

How much memory is the Window Server using? I don't have that on my iMAc.

It says 24.12 MB on Real memory & 185.35 MB on Virtual Memory

I would try a Repair Permissions and a reboot. See if the problem keeps happening.

The only time my fan starts making a lot of noise is when it has locked up or crashed which unfortunately happens frequently. Three weeks ago I purchased an iMac G5 and I'm not a happy camper. It crashes whether I'm surfing the net or working in Photoshop. Does anyone have any ideas why it keeps crashing?
The iMac came with 10.3 and I have upgraded to 10.4.2, I've run Disk Warrior and the apple hardware test and everything seems to be okay. I've gone so far as to re-initialize the drive and re-load everything. The only software I've installed is Photoshop CS and MS Office.
I have been a Mac fan since 1987 beginning with an SE, followed by a VX, Power Computing 603 and the G4 AGP so I'm no stranger to working on a Mac.
If anyone has any ideas please post them. Thanks.

I have already done all of those things and run Disk Warrior and Tech Tool Pro and Cocktail and Internet Cleanup and even done a complete system install TWICE and nothing solves the problem!

What screen size do you have. Mine flares up and doesn't stop at random intervals and also when: I boot from a disc, target mode it, but it will also do it in sleep, when its running nothing. I am very, very dissapointed. It was in apple's repair shop for 2 months, and they 'couldn't' find anything wrong with it. I am really pissed off now!

I'm out of ideas, here. If it's still under the 1 yr warranty, get the APP. I'm getting the feeling that this iMac G5 is not one of Apple's best iMacs.
