iMac G5 won't power on even after replacing power supply, help!
I have had this iMac G5 model forever and am not ready to let it go. A little before the holidays my computer started to make some loud crackling noises that were very intense? I shut it off manually. Started it back up later -- no problem for a little while but eventually the noises started again so I unplugged everything.
I set my computer near the window to stay cool after the initial noise night. Turned on great in the morning before work! I just happened to not have external enough memory to save all my photographs and music. I shut it down properly...but when I returned from work at night with more memory, the computer decided to not function normally again and could not boot itself up.
I did the diagnostics trouble shooting from apple (http://support.apple.com/kb/HT2173) and my LED 1 is on, and LED 2 lights up momentarily.
I figured it was a power supply issue due to the above link.
I went away for a week for the holidays. Decided I'd try the computer again...it had a holiday miracle and turned on again! But once I was to my desktop and trying to get my files off it began the noise so I immediately unplugged it. Being able to access my files time after time for short periods makes me believe that my hard drive was not damaged and I am grateful for that.
But now that I have purchased a "fully tested and functional power supply" from the Internet and successfully replaced my old one, I am wondering why my computer is STILL doing the same LED light indications and not starting up.
What else could this mean? I hear a "clicking" noise when I "start up" the computer from the back panel being removed where the fan gives a little jimmy but then stops. But it literally sounds like a click and I only see that fan action for .2 of a second with the momentary LED light display. Is there still other parts that would affect the power supply?
This is my first computer repair and I am not sure where to go to next so I would greatly appreciate if anyone can provide some clarification and guidance to getting my computer functioning properly again.
Is this a good question?
