Re: [Avid-L2] Mac Gurus, please help

oh, also boot into verbose mode (you'll have to look it up) and when it panics you should see a clue what it was doing when it crashes. it'll say something like kernel panic bla bla bla backtrace and something there i think.

greg, at this point the only thing i can think looks like you didnt try- bad gpu (have you tried a different gpu?). other than that something is probably wrong with a motherboard component, maybe the apple intel power management system, lots of stuff doesnt get initialized at safe boot like cpu and power management stuff.

if a gpu swap doesnt work, find a used one somewhere, definitely not worth your time- you've got much more important things to do!

I'm still having the 'lock up' trouble with my MacPro 3,1 - essentially,
it runs for about 3 minutes, then rainbow pinwheels in perpetuity.

It started doing this about two weeks ago- no known change in software
at that time. It does NOT do this in 'safe' mode, which makes me think
it's an OS or extension issue - but that doesn't seem right after
today's attempts to repair

I've tried the following, with no change in outcome (it always stalls in
2-3 minutes of operation when booted not in safe mode):
- deleting the most recently added kext files (there was only one from a
few weeks ago - everything else is months or older)
- creating a new user
- re-installing the OS
- creating a 'fresh' OS install on a different hard drive - booting from
that drive
- removing memory in pairs, booting with minimal memory and different
configurations
- booting from a 'known good' HD from another machine
- swapping in a 'known good' graphics card
- removing all PCIe cards except gpu (although they all work correctly
until the 'stall' happens

and anything else I could think of and maybe haven't listed here.

What am I missing? What else would cause this? Clock battery? It's a
macpro 3,1 that's an assistant's station and if it uses much more of my
time to repair, it may just have to be retired. I just don't want to
spend the cash to replace it right now!

Any clues or suggestions appreciated.
