Question about Apple iMac Computers & Internet
I have iMac computer made in 2008.RAM 2GB.Recently it frequently freezes up (beach ball appears and no matter how long I wait it does not go away) Disk Utility does not indicate any problems .Considering this and the fact that I do not hear any clicks,noises etc makes the impending failure of HD unlikely.The only way to deal with the problem is to switch off the computer is using a power button.Switching to another browser does not help.It can happen regardless of what I am doing eg accessing a webpage reading email)When these problems occur there is usually approx 50% of free memory and a lot of free space on HD.I did not recently install any new software My operating system is OX 10.8.6.

When you say you've used Disk Utility, have you done both Repair Permissions, and Repair Disk? For Repair Disk you need t boot from a different drive, the original install DVD if you have it?
Another thing to try is, remove and and then replace the RAM chips, sometimes the connections need to be re-seated.

You are going to need a system install disk for this machine if you want to reinstall it. However, if you just want to run diagnostics, any system install disk for MacOSX should do the trick. You just won't be able to run the installer once you boot from the DVD. The first thing I would do is make sure the eBay seller sold this to you in this condition and without the install disc, because if not, you've got an issue with them.
If you don't have an install disc, your cheapest solution is to call Apple and order a replacement disc for your model computer. You will need your serial number, which you can find on the sticker on your computer. Good luck, and let me know if you need more guidance with this.

it won't read it because the new os disk is double layered and the g4 drive you have probably won't read double layered dvds. best solution is to buy or borrow an usb external dvd drive. i did this last week and it worked fine.

SOURCE: wont start up completly
there is the single user start-up, which you were thinking of. There is also a safe-boot for macs.
To start up into Safe Mode (to Safe Boot), do this:
1. Be sure the computer is shut down.
2. Press the power button.
3. Immediately after you hear the startup tone, hold the Shift key. The Shift key should be held as soon as possible after the startup tone but not before.
4. Release the Shift key when you see the gray Apple icon and the progress indicator (looks like a spinning gear).
During startup in Mac OS X 10.4 or later, you will see "Safe Boot" on the login window, which appears even if you normally log in automatically.
During startup in Mac OS X 10.2 through 10.3.9, you will see "Safe Boot" on the Mac OS X startup screen.
To leave Safe Mode in any version of Mac OS X, restart the computer normally, without holding any keys during startup.

They are a few thing to try althoguht you may have already tried them;
Pram and PMU reset -
First turn off the iMac, once turned off unplug everything from the IMac and physicallly unplug it from the wall, wait about 5 mins at this point, then just plug in the very basics (keyboard + mouse) - this is the PMU or power management unit aspect of this - the next step is a PRAM or paramiter RAM reset
To do this hold down the apple + alt + p + r key on your keyboard just after you turn on the iMac, and keep these held down, you should hear it chime as normal, now if you keep holding down the keys you shoud here it chime again, keep the keys pressed down till you have heard 4 chimes in total.
After that is done let go off the keys and the iMac should restart as normal - can you eject the disk now?
Sadly System profiler is normally very effective at picking up hardware that is installed in your Mac, The fact that it is not brining up anything would suggest that the super drive may be faulty or somehow disconnected, if you try the above and it does not work then i would suggest you call a AARC or apple authorised repair center and have the S/N: Serial number of your Mac ready - you can find your local repair center on the Apple website - for example the closes repair center to me would be Jigsaw Solutions LTD (www.jigsaw24.com) who are the UK's largest retailer of Apple abode and Quark.
I hope the above is helpful and that you do not need to contact an apple authorised repaird center!

SOURCE: IMac G4 completely dead!
It sounds like you may have tried this already, but I'm not sure.
Unplug the computer, disconnect the power supply form the logic board, and remove the battery completely. Let it sit this way overnight. Reassemble it and try again. It dissipates latent electricity from the board.
