My Troubled Mac – Part 2

Saturday, July 4, 2009

The good – It boots and runs

The bad – One kernel panic, one freeze

The ugly – Difficult to isolate the problem

 

Yesterday, I started the process of evaluating and fixing My Troubled Mac. It’s an Apple G4 1.42 GHz Dual Processor FW800 MDD (Mirror Drive Doors) model that has been prone to frequent kernel panics and freezes. My goal is to isolate the source of these problems, then decide on a course of action.

I started by removing all the hard drives, a USB 2.0 PCI card, and the Apple Internal Modem card. I installed a single hard drive, which is known to be good. I then reset the PMU. I left the DVD drive, video card, and RAM installed. So I now have a basic hardware configuration for testing.

My Troubled Mac

The good – My other Macs work perfectly

The bad – Repeating kernel panics

The ugly – Appears to be a major hardware issueg4mdd

 

On July 4, 2006, I purchased a used Apple G4 1.42 GHz Dual Processor FW800 MDD (Mirror Drive Doors) Mac on ebay. The total cost, including shipping, was just under $900. I thought this was a pretty good deal, since it was a 2nd generation version, with quieter fans, updated power supply, and copper CPU heatsink. It came with 2 GB (4×512)of RAM, two 80 GB hard drives, Pioneer DVR-105 SuperDrive, Iomega Zip 750 drive, ATi Radeon 9000 Pro 64 MB video card, Apple internal modem, Apple Extended USB keyboard, Apple Optical USB mouse, and system restore disc.
