My Powerbook G4 1 GHz 1 GB RAM 60 GB HD Last TiBook Revision, Nov. 2002 possibly died a few days ago.

While playing a DVD connected to a TV (displays synced), it suddenly stopped with mezzoforte fans, screen froze. Note: we had around 35°C these days. After a restart with ctrl-cmd-power, it boots up and freezes frequently -- sometimes with a black screen, showing only a little something of gray in the bottom, sometimes with the last screen without mouse pointer.

What I tried:

• boot from Tiger CD, repaired permissions and both partitions, 2 runs until 1 clear run
• boot from DiskWarrior, running Diagnosis a several times until 1 clear run
• zapped PRAM
• PMU reset
• Apple Hardware Test, everything's ok
• Reinstalled 10.4.7 update --> crash after update
• HD formatted, 10.4+10.4.7 combo updates installed --> crash while installing, boot worked, crashed while entering personal data
• Original recover DVD installs fine, crashed Welcome movie

This could be a graphics chip heat issue?
There is only 60 minuted or so to go. I don't want to work in the fridge, even if this would help ...
After 3.5 years of long runtimes (2 y. as desktop replacement), I'd be not too angry about this.

But I strongly wanted to ask you experts in here before selling it as a defect PB on eBay ... any ideas, someone?

No opinions yet? Is my English too bad? Is my loved PB really dead? Plz let me know what you think ...

Nothing wrong with the English.

I have a TiBook 667 DVI myself and it tends to run hot (was 'folding' on it) so I have a cooling fan for it to help dissipate heat.

As for your problems, you might have been better giving less info to entice people in the problem. At the moment you seem to have done everything that you should do, and any suggestions now would be more wild speculation (and open to ridicule!!!)

Saying that, are you sure it is not the HD? Can you have it running from an external for an extended period of time?

I think your OS is hosed, if you don't have an external HD to run from Boot from Tiger DVD and leave it on for a while. Or run a ram check or screen check and make sire its the OS!

Thanks for your opinions.

Unfortunately I forgot to mention that I even tried the external HD option: I did install Tiger on a firewire drive that resulted in the same behaviour with the screen. maybe this happened a bit later, but same game.

The OS option (was my first idea, too) isn't the solution, like you read above, I even formatted the HD and installed a clean Tiger. An later on, even the clean install of the original recovery did not work.

So, you all think that it could be dead? Even if it can running for around 45 min. before crashing hard? Is there one last way of diagnosis that I could go?
