How to repair my iMac G5
iMac G5 17 A1058 start to die plus display trouble
My Imac was starting to do strange things on the screen, or sometimes was going full grey. And I had to restart manually?
I tought it was the Nividia graphic card.
I did open all, cleaned up old thermical paste and made a new one. Also made deep clean of ventilators.
Then reassemble the computer who turn on and work.
But problem is getting worst.
Sometimes not even time to wait for the overall start.
Already bloqued, or impossible to do anything.
Still some trouble spotting on the display.
But display stay stable and computer isn't running anymore.
I did check the 3 ventialtors, they work.
But the cover of the "big stuff" aluminum color with the big G5 logo is getting really hot and very quick.
Does any body know or have any idea ?
Thank's for all.
Here I am.
New used combo installed and does work.
The computer does only start on Safe Mode.
Actualli is Installed with macOs system is 10.4.11
I do only have original CD OS 10.2
With this OS 10.2 CD It doesn't boot on Hardware test.
when I try to boot.
I can read on screen : "Invalid memory access at SRR0 and SRR1"
But trying the Hardware test (mac-boot + return) nothing happen.
I've tried to install OS 10.2. Unfortunatly after restart for new installation.
The screen is showing one black rectangle in middle. And nothing else happend.
I that correct to try to install OS 10.2 instead of actual 10.4.11 ?
Or better to try to install OS 10.5 or 10.6 ( I have CD of thoses).
I'm stuck !!!
please any advice.
