I have 2 mac G4s that will not start up any more
dual 1.25 OSX 4.11
I upgraded to leopard OSX 5.8
in order to get latest i tunes to activate an iphone
Shortly - the computer would no longer start up.

I moved the hard drive to another G4
shortly it would no longer start up

I put the "back up" internal hard drive I had in the first computer
into the second computer
I got new batteries
I reset the PMU on the logic boards.

The second G4 would sometimes start up - usually not

I got another 1.25 G4 - different hard drive - OSX 4.11
it starts up
I took some word files that were on on a back up disk - copied from
the first hard drive.
Now this computer randomly freezes up - Word or Safari
I have to unplug it and restart.

Any possibility you used a gray Leopard DVD (made for another model of Mac) to install 10.5 on the two G4s? That would be the problem. Gray DVDs only have motherboard drivers for a specific model.
