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.

Power Mac G5 (Late 2005) Quad 2.5, Mac OS X (10.5.4), Currently 4GB RAM, 2 GeForce 6600 Vid Cards
