I think I fried something in my iMac

[OneMoreMacUser]

Well the title mostly explains itself, when i go to start up my iMac it turns on does its chime, waits about two seconds and then dies. If I unplug the machine and wait for a little bit i can make it do that again.

Before the iMac "died" I was using Apple works 6 on Mac OS X 10.2 and it had gone through many install processes and I had to keep unplugging the thing because the CRT was turning off unexpectedly multiple times, sometimes it would turn back on and shake, but mostly it turned off and there was nothing i could do! So I had to unplug it! After installing the OS and updates and the unplugging multiple times I think it died, my bad.

So from the symptoms and the circumstances, what should I replace, or try to do to fix it.

It's possible the power supply is going bad or the graphics card. Can you determine if it boots up fully, but with no screen?

Like mentioned before, does it boot fully up but without display?. Maybe the CRT is failing itself? I have some failed CRT´s that made that behavior before dying.

How do I check if it boots "fully" with the CRT dead?
Is there a button I can press?

Listen for any other sounds, attempt to log in with your password (if you have one) by guessing when the log on screen is there. Try playing some music by pressing the play button on the keyboard - if you have it.

Remember the computer shuts down a couple seconds after turn on.

Well then I would start looking at replacing the power supply. What kind of Mac do you have?

Getting a power supply for the one I have is hardly worth it, for me right now.
It's an iMac g3 rev. A, all the power supplies I have found are about $80

That sounds about the going rate. I replaced the PSU in my iMac G5 and it was about $60.

in a lot of cases with these g3 imacs it's much cheaper just replacing the entire computer than an individual part.
