    So, my G5 is just problem after problem anymore. I fixed my RAM issues, now rocking 3GB of healthy DDR sticks. I popped in a new healthy 320GB WD Blue drive and cloned a fresh Leopard install to it that I have on a backup 60GB hard drive I keep around.
    Now it is much faster and even a tad less noisy (Fans don't run full blast as much anymore) but I still get constant crashes which is leading me to believe a CPU is failing.
    What happens before a crash? The program running locks up, one CPU ramps to 80%-100%, and the other goes to 5%-23%. Then I either get a kernel panic (happens most often) or the program crashes.

    Heres my most recent error log:

    Interval Since Last Panic Report: 54689 sec
    Panics Since Last Report: 1
    Anonymous UUID: B7053A18-C0D2-4289-B3FD-DE393B66AEDB

    Also, the crashes aren't terribly frequent. I can perfectly use the G5 as my main desktop still. But the crashes are still a thing that I have no idea how to fix.

    @WalnutSpice I recommend that you go ahead and do an extensive hardware test using Apple Service Diagnostics (ASD). I believe you need an AASP to source this.

    Can you pull one CPU out and see if the problem goes away?

    Keep in mind that a G5 requires a CPU to always be in the CPU A position to boot.

    I wouldn't know which one to test. Sometimes CPU A will go to 100% and B will go to idle, and sometimes CPU A idles and B runs up towards 100%. And I hear of a lot of people damaging the CPUs even when being very gentle with them, so I wouldn't want to risk it doing that myself. I do have an Apple Extensive Hardware DMG though so I can test it through software. I just need some burnable DVDs.

    I was thinking you could just guess. If the problem is still there, then swap to the other one. There's a CPU preference pane thing around, I think it came with xcode, that lets you disable a CPU in software. That might help diagnose the problem.

    Although if you've already seen that it's not processor specific, then it may be something else. Perhaps still related to your earlier RAM issue?

    I'm pretty sure it's not RAM related anymore. When it was, I had loads more issues then I do now. But I'll definitely check disabling a CPU through software.
