Try reseating your RAM one stick at at time in each of the slots. Here's how: iMac G5 17" Model A1058 RAM Replacement

Check the capacitors on the logic board for swelling and/or corrosion. Note the diagnostic light in the center of the logic board and tell us your results.

OK, I reseated the ram. I have to order tools to get to the logic board. I'll get back to you when i get it done.


What I can see of the logic board looks fine. I plugged it in, the only light on it had an arrow pointing to it and it was green.


Do you have one or two RAM sticks? If only one, did you try it in both slots? Will it completely boot from the system installation disk (not the AHT)?


It wouldn't install the original software.It got so far and I got an error message.

I tried disk repair from the startup disc. It finished and said:

Checking extended Atributes file-invalid leaf record count-(it should be 600 instead of 150) I tried to boot it agin and i got a white screen with some typing in the upper left hand corner that said 'invalid memory------Type mac-boot. I typed mac-boot and the screen turned pink. I shut it down with the button onthe back and it spit the install disc out and shut down. Any ideas?


Please tell us about the RAM you are using
