You didn't mention what G4 you have, but if you have the hardware test
CD, it will/should test your memory. 10.3.9 is very particular about
ram. I had ram sticks that worked just fine under OS 9.2.2. but made
the system completely unstable with Panther.

In a few of my machines I couldn't even install Panther. The installer
would stall. In a G3 I recently upgraded, I just got the spinning beach
ball of death.

If you don't have the hardware test CD, I'd pull all but 1 stick of
memory out. If that still crashes, pull it and replace it with another
stick. Chances are, not all of your memory is bad.

Good Luck.

Quite simple: the machine freezes up. It does not respond to keyboard
or mouse and the only thing left to do is reset.

2. When you tried adding new memory did you just add, or did you try
taking the old stuff out? Memory can fail and (in my experience) it's
one of the most common causes of an unstable OS X box.

I believe I stuck 2 additional memory cards in without removing
original ones. When I get a chance, I'll open it up and take out the
old memory and see what happens. Thanks for the input.

I'll need to look for that CD. Don't remember if it came with the OS X
or not. Sounds like something I should be able to download for free if
I don't have it, no?

Not necessarily. Those hardware test disks didn't come along until after
the early G4s. We have a Sawtooth, didn't come with one, and your 1998
date makes me think you've got either a Sawtooth or a Yikes.

One more thing. USB devices have a history of causing problems
for Macs. There have even been reports of a broken mouse causing
problems (the user didn't know it was broke, but when they
replaced the mouse, their problems went away).

So, if you have multiple USB devices, remove all but the keyboard
and mouse (as a test). This includes a USB hub as well.

If you have another keyboard and mouse, try substituting them (as
a test).

But as has been pointed out by others, memory is the #1 cause of
Mac instability.
