So i've been having an evergrowing problem with my G5 quad 2.5 box over the last year or so. It started very rarely freezing while it was sleeping with the fans blazing. Over the last couple months it has become drastically worse... it is freezing nearly 3 times a day now, sometimes when it's asleep, sometimes when i'm running it. There is no common symptom for applications or anything.

I read a report that said to check my logs for PanicReports. I have over 100 panic reports in the last month.

I have ran full Apple Hardware tests stating nothing is wrong... as well as a number of RAM tests saying the ram is ok. I've switched out between 3 pairs of RAM sticks, as well as disconnected all peripherals... but had the problem still occurs under all states. I do have 2 video cards that I haven't tried testing without yet.... other than that, I can't find any sign of a hardware failure.

The kernel_panics all vary, but most looks similar to this:

Please help, any information would be great.... this is averaging 3 times a day, and its getting very inconvenient. This is a very fast box, and I am very curious as to what is causing this issue.

    Hi-

    What are the two graphics cards?
    The "com.apple.NVDAResman" is noted in graphics card problems in other forums.
    Though a failure is possible, a conflict between the two cards is suspect.

    What manufacture FAM do you have? You may have bad RAM. Start by replacing with factory RAM. To eliminate it as a possibility.

    Have you read through this:
    http://www.xlr8yourmac.com/systems/G5coolantleaks.html#updates

    As well as reports on Mac news sites (MacFixit, MacIntouch, etc)?

    You shouldn't be having this, or that many, and not take it in for testing.

    Using just one video card, then the other, would be normal trial and error to narrow down, just as you said you tried ruling out external cables and devices (and yes, even a bad FW or USB cable can cause panic).

    @ BleedingStar

    I just wanted to let you know, that you are not alone with this issue. I have a Quad G5 with the exact same problem. It started when I upgraded to Leopard and at first I might have had one a week, but now I rarely go a day without it happening 3 times in a single day.

    I've done the usual, replaced ram, re-installed Leopard, etc.

    I would be very curious as to what you find out. I know I need to take my computer in, but I'm putting up with it for now, since this is my main work computer and I don't have another one to fall back to.

    Friend had Quad, on-site 'Care, 3rd logicboard and ALL of the small and large issues with Photoshop and other applications vanished.

    Of course you want to watch for heat, fans, leaks.
