OK this is what is happening. Its a bit complicated

My eMac was working fine. I restarted it and the following situations occur.

1. It starts but the screen is black. sometimes it starts and the chime occurs and but the screen stays black and the eMac remains on.

2. It starts with no chime just 4 loud beeps and the screen is black and eMac stays on.

3 It starts and the white Apple screen is displayed along with the spinning dash wheel. the wheel spins for a while and then stops and the eMac shuts down.

Sometimes when the emac stars and there screen is black the little light on the front panel will blink four time and then remain lit.

Any advice would be much appreciated.

It is a 1Ghz eMac. 2004, the model with the 1.1 USB bus ATI graphics.

EMac 1 gig, Mac OS X (10.2.x)

    ok I followed that link and found something like this:

    4 beeps = no good boot images in the boot ROM (and/or bad sys config block)

    I can find a lot of info about the beeps but nothing about what it really means or what to do.

    Hello again Dominick,

    1. Don't go poking around inside that eMac unless you know EXACTLY what you are doing in there!

    2. Have you changed any RAM chips there?

    3. Has that emac been subjected to a jolt or sudden movement recently? Ergo - Before this issue manifested itself?

    Regards.

    Have you run Apple Hardware Test? It's on one of the CDs that originally shipped with your eMac. Put it in, and reboot while holding down D. It won't fix anything, but it will tell you if a trip to the repair shop is needed.

    Ian, Thanks for your help!

    New RAM was added a year ago with no problems.
    The eMac has not been subjected to any sudden jolts.

    I have taken the eMac to the Genius bar at a local apple store but the techs answers were sort of vague.
    He said it could be bad RAM but that they had no RAM old enough to replace it to rule that out. He reseated the RAM and I think he swapped it around. I believe I have to sets of 512K RAM to equal 1Gig total.

    He thought maybe it could be the mother board but he did not know and really offered very little conversation or answers.

    He said I could try finding new more RAM from somewhere and replacing it (which I know hod to do) but other than taking a chance on buying some new RAM I don't really know where I would get it. If I knew for sure it was just the RAM I'd order it right up!

    He didn't think it was an HD problem.

    Sometimes the grey screen on the eMac does come on about every 5 power up tries. Then the little gears spins for a while and stop and the machine shuts down.

    I now have a new iMac and all I need now is a way to get the info from the internal eMac hard drive (although I would like the use of the eMac).

    Is there a way to access the hard drive through an ethernet connection or some other way from my new iMac?

    My only options seem to be to buy new RAM and try it out, and or remove the internal HD and buy a connecting USB case and run it from the iMac.
    But I don't want to give up on the eMac just yet.

    Thanks for any suggestions.

    Kiraly. Does that disk come with any new OSX packages? Like Tiger? Because I have Tiger which I installed a while back but I don't think I have any "original" discs that shipped with the eMac from back in 2004.

    Also, will it boot up from a disk? I tried to boot up from a Tiger OSX disc but nothing.

    No it doesn't. It only comes on discs that ship with new Macs. Because every Mac has different hardware, it would be impossible for Apple to include a "universal" Apple Hardware Test with retail versions of OS X.

    Here is a very old Apple page where you can download a disk image of Apple Hardware Test for the eMac, then burn it to a disc and then boot from it. But I don't know if it supports all eMacs or not.

    Kiraly,

    I actually found the original disc! But my screen is not working so I cannot see anything.

    Here's the thing.

    Sometimes the eMac starts and beeps and flashes.

    Sometimes it starts with no beeps and flashes but the chime is distorted. In this case every once in a while the grey startup screen does come on. The little gear indicator spins around for a while and then the eMac shuts down.

    I'm wondering why it sometimes starts (no screen) and gives the beeps, but then sometimes it starts with no beeps but the grey screen comes up.

    Either way I cannot seem to get the eMac to give me a screen to work with.


    I'm also wondering if I can somehow connect my iMac to the eMac when it remains on but with no screen and access the eMacs internal drive from my iMac to migrate the info.

    New Development!

    I got the eMac to start up from the Tiger install disc and ran disc utility to repair the HD. There seems to be a directory problem that disc utlity cannot fix but in the past I have used Diskwarrior 3 to replace the directory with no problem.

    I have accessed the Network utility from the install disc and I have the menu up now.

    Does anyone know if I can hook up my iMac to my eMac using this network utility so I can migrate my info to the iMac?

    I am afraid to shut down and try to boot from the Disc warrior disc to fix the directory in fear I may not get the eMac to boot again.

    I'll be waiting for suggestions?

    I have used Diskwarrior to rebuild the HD directory but I cannot get the eMac to boot on its own so I shut down the eMac and tried to start it.

    All the beeping and flashing is gone but first thing I get is a quick screen with a folder that blinks once with a question mark then the eMac goes into the grey apple screen with the spinning gear forever.

    I feel I'm making progress because at least now I have a screen to work with.

    I still need help. anyone?

    It seems as if the eMac cannot find a system to boot from the HD. Can I make a bootable disc on a DVD and use it to boot with?

    All I need to do is to get access to my drive for migration to my eMac.

    HELP!

    Thanks

    Boot your eMac while holding down T. Then hook it up to another Mac with a firewire cable. It should mount on that Mac's desktop as an external firewire hard drive. You can then grab your files off of it.

    Kiraly,

    I have a 400-800 Firewire adapter arriving tomorrow so I'll update you on how it all goes.

    My old eMac only has firewire 400 and the new iMac only has firewire 800 thus the adapter.
