I have a IMac G3 slot loading and it wont boot up every time?   Some times I trun it on it go to the apple and boots up.   But most of the time its just a gray screen and then a fast white screen than back to gray with a folder?   When it does come on it freezes when its on for maybe 10min or if I try to download to a flash drive(to remove all my stuff).    I think its running 10.3.9 or some thing like that.  Is There any way i can get it to work again?   Also the cd/dvd burner is not working when I put a cd in it gets stuck? I read that I need to reinstall os 9. But i dont have the money to get one or where to find one.  I also read I need a new hard drive but I need to get some of my stuff off .Also when its been unplug for a few and i plug it in and trun it on the light comes on then it makes a pop sound and shuts off and wont turn on unless i unplug it and plug it back in. I really like to get this IMac to work again.

 

Any Ideas or tips? also when I do option key then power on it wont read its hard drive?

 

when I do the Command, Option, P, and R keys and try to type the

 

reset-nvram ( it lets me do this one)

set-defaults  (the 1st time I did it, It said "bad defaults") but when I try to do it again it freezes)

reset-all ( I only did this one 1 time and it restarted but did the same thing)

 

If I get the USB to Sata/ide would I need just it or the whole power cord too? could I just but on tiger(10.4) and use a usb cd burner

I also got a new clock battery.

 

Thanks For sticking with me in the long post but if you can help let me know.

    I think the popping sound is the power supply going bad.  Or maybe the fly-back-capacitor going bad.

     

    you need to reset the Mac's PRAM, NVRAM, and Open Firmware. Shut down the Mac, then power it up, and before the screen lights up, quickly hold down the Command, Option, P, and R keys, until the Mac has chimed twice more after the powerup chime. Then, before the screen lights up, hold down Command-Option-O-F until the Open Firmware screen appears. Then enter these lines, pressing Return after each one:

     

    reset-nvram

    set-defaults

    reset-all

     

    "The reset-all command should restart your Mac. If so, you have successfully reset the Open Firmware settings."

    Which iMac do you have?  slot loading or tray loading?  Firewire or not?

     

     

    Query by serial number

    Apple's warrenty database will identify the type of Mac you have.  Your serial number is securely sent, but you get only the name of your machine.

    https://selfsolve.apple.com/agreementWarrantyDynamic.do

     

    This site provides more information, but lacks security.

    "A serial number is a unique, identifying number or group of numbers and letters assigned to an individual piece of hardware or software. It's used for various things depending on the product / brand but what is your Mac's serial number for and more importantly... what is it hiding and what can it do for you ?"

    I'm going to assume it is a hardware problem.  To get your data out, remove the harddrive & place hd in an external hd enclosure with an ata/ide connection.

     

     

    When it does come on it freezes when its on for maybe 10min or if I try to download to a flash drive(to remove all my stuff).    I think its running 10.3.9 or some thing like that.  Is There any way i can get it to work again? 

     

    What the problem with copying?  Should be able to copy lots in 10 minutes.

     

    Your data is at /Users/your-short-user name

     

    copy by folder.  Look what you got on another computer. 

     

     

    I read that I need to reinstall os 9. But i dont have the money to get one or where to find one.

     

    Were did you read this?  It could be a software problem, but with the popping sound, I'd go with hardware.

     

     

     

     

     

    If I get the USB to Sata/ide would I need just it or the whole power cord too? could I just but on tiger(10.4) and use a usb cd burner

     

    You need an external FireWire drive to boot an iMac G3. Does your machine have firewire port?  Get something with a power cord. The usb drive will be no faster than your flashdrive.

    Like I said its a slot loading and it does have the firewire.

     

    as for copy it freezes at 10min if I dont do any thing with it just leave it on.

    but when I try to copy it freezes half way downloading and the hard drive make noise like it reloading and the freezes.

     

    do you have a link to the firewire cable and or the hd external hd enclosure with an ata/ide connection.

     

    how do I tell if its the popping sound is the power supply going bad.  Or maybe the fly-back-capacitor going bad.

     

    also it freezes at the


    reset-nvram

    set-defaults ( its stops here and it wont load)

    reset-all

    also if I get a 80gb with mac os x 9.2.2 on it would that work as a new hard drive and would it boot up again?

    I think you can find these cheaper, but this will give you the idea.

    I got a new hard drive(it works great now) with 9.2.2 on it can I buy Mac os x 10.3 and down load it to the 9.2.2 or do i need other Mac os or Mac os x

     

    Thanks

  • rccharles Level 5 Level 5 (6,495 points)

    You can install 10.3 on top of 9.2.2.  This will allow you to dual boot.

     

    Slot loaders can run 10.4.  I'd recommend 10.4 because you can run web browsers that will view all web sites with the exception of video.

     

    For tiger, you need 256meg of memory.  A slot loader will take 1gig of memory.

     

    You may need to get more memory.

    get the 512meg card(s)

    I tend to think dashboard is neat, but not neccesary for my everyday workflow.

     

    it is possible to enable and disable it as needed,

    by entering the following commands into the terminal:

     

    -- To turn Dashboard off:

    defaults write com.apple.dashboard mcx-disabled -boolean YES

     

    -- To turn Dashboard on:

    defaults write com.apple.dashboard mcx-disabled -boolean NO

     

    -- You have to restart the Dock after making either change for it to take effect:

    killall Dock
