Help! My dual G5 2.0GHz won't boot. I bought it October of last year, so the warranty just expired.

The video card died earlier this year, Apple retail replaced it under warranty. When I watch DVD movies, the whole system will often freeze up, the fans speed up to hurricane force levels and I have to reboot the machine using the power button. A long time ago, I had to buy Diskwarrior to fix the main drive. This was a while ago though, and in fact the Diskwarrior I have now does not work with 10.3.x boot drives or whatever, even though it did work with 10.2 or who knows what the cut-off version was.

That's the history, here's the problem.

I can't get past the multilingual you must reboot this computer warning.

I have tried to boot from OSX CD-ROM. I get the multilingual warning, and then oddly enough, a blue screen.

I have swapped the 2 SATA 160GB drives around. No change.

I pulled out the 2GB of Crucial RAM and left just the original 512MB of Apple OEM RAM in there, no change.

I tried booting into single user mode, I could do that, but don't know what kinds of commands I can type to get some diagnostic information.

I tried to research the issue but found nothing, especially since my search terms are so generic - reboot osx won't boot

Any tips on how I could better diagnose what the problem is before I pay$$$ to take it into Apple?

I basically left this computer on all the time. I'd put it into sleep mode. I went out of town for a week and so I actually turned it off. Came back from vacation and it won't boot.

As if I even need to mention this, I have a client dying to meet with me to do some work, and I'm dead in the water. I have a 15" powerbook, but the files I need are on my dead G5.

Thanks!

Tried to target my Powerbook via Firewire holding down T when booting. Same error, and it also crashes my Powerbook.

Hold down option to get into open Firmware, still errors using the Start-up drive.

Can't boot from Tech Tool 4.02 CD. Same you must reboot error.

The only thing I can do is cmd S into single user mode.

What are some diagnostic commands that I can enter in single user mode.

They damn fans hit full speed eventually in single user mode...

argh... third major problem with this Mac in a year...

fsck -f

says the boot volume appears to be ok...

[sodamnregistered2]

did a cmd-v startup for verbose...

seems kind of normal, then...

Panic(cpu1): jnl: do_overlap blah blah

Latest Stack Backtrace for CPU1

some stack trace stuff, then at the end...

Panic, we are hanging here.

Are my CPUs fried?

Took computer into Apple store. It's being sent out for repair, they will call me sometime after Thanksgiving.

Looks like a CPU may be bad...
