Re: imac g5 is so noisy
Fan sometimes get stuck on, I won't bore you with the technical details as to why or the terminal command to fix. Just do this...
Shut down. Unplug the power cord from the back of the tower. Wait 15 minutes and plug it back in. Power up, it should have reset it.
The fans are "smart", some of them are designed to run only as needed, sometimes they get a little tangled up in their own underwear.

Hi John Try reinstalling via your macbook pro but this way round.Put the Leopard Disk into the Macbook and then start the Macbook in Target mode.on the iMac start it up and hold down the Option (or Alt) key then wait.after a short while you will be offered the HD in the MacBook and the DVD. Choose the DVD and see what happens. What happens when you do it the other war arounds is that you are installing a startup system for the MacBook onto the HD of the G5 and not the system for the G5. The installer uses the firmware of the motherboard that is running the install to select the correct version. Another issue is that the disk formatting may be wrong. it's unlikely seeing that you used disk utility from the DVD, but it is possible. Let us know how you get on.
Bad capacitors often cause the no-turn-on problem. This page has a good picture of what bad caps look like in the G5. If you see this trouble in your G5, you might be able to get this going. Kits of capacitors are available (here's the place I got some from) and If you're comfortable with electronic soldering and replacing parts on a printed circuit board, changing out the duds may be all that's needed. I've seen three of these now. On one, there was just a single bad cap that was keeping the computer from starting up. It's certainly worth looking into.
It should not affect the data on the hard drive but with all repairs such as this it always worth making sure you have your hard drive backed up. I had a similar problem with a imac a couple of years ago and the hard drive was fine when it came back. Hope this helps.
Get out your Mac OS disc and restart your computer and get that disc into the drive. You may need to restart with the disc in, but that's ok. Just restart again with the "C" Key pressed and the computer will launch with the OS disc, and then you can access the file menu when it finishes launching. Choose "Disk Utitlity" from the file menu and you can repair the system files on your hard disk. then restart without the disc in the drive. K
I have one doing exactly this at the moment. It had gone to sleep and the fans were going like crazy.
I think it is a Motherboard failure (it happened with many G5 iMacs), this one has been replaced once already, and I can't actually get it to install anything.
I'm taking it apart tomorrow to see what I can find inside. If I fond anything I'll let you know.
