Mac OS X 10.5.8 Freezes randomly

Hey there,

I'm having an issue with a PowerMac G4. It is freezing randomly and I just can't figure it out!

When it freezes, the system fully locks up. I.e. No spinning beach ball. The mouse won't move, the keyboard won't work,and the clock stops ticking.

The system is basically a fresh install of Mac OS X with a new hard drive. I've used tech tool pro's boot CD to run a full diagnostic test. All hardware comes back SOLID.

I'm attaching two different system log files of the time it happened. One time was 8:33:05
The other was 8:20:58

I included from when the computer initially started up, to 5 minutes or so AFTER it was shut down and rebooted.

I'm wondering about the USB lines the occur every 5 seconds. If I unplug the USB hub, these errors STOP. I tried replacing the USB hub but the errors and freezing both continue.

I'm stumped...I know I must be missing something but I'm pretty confident it's NOT software related, since it's a fresh install. I'm also pretty certain it's NOT hardware related on PowerMac itself. (It could be with a peripheral?)

Thanks for any advice you can offer!!!
