And they said Macs don't crash. This is like the 4th time over a couple months. I wrote down the crash message. Anyone know what's wrong? Is my ram going bad(i bought from Crucial) or did an app cause this?

Try running the Apple Hardware Test that came with your machine. If you boot to the Hardware Test disc and then hit ctrl-L, it will loop the test for you. Sometimes it takes a few tries through to catch bad RAM.

You could also take the PowerBook to an Apple Store or other service provider and ask them to run Apple Service Diagnostic on it. It is generally more comprehensive and can better detect problems with parts like RAM. It is not perfect, though.

The best thing to do would be to pull the additional RAM out of the machine and try to reproduce the crash. If you cannot, it is likely the card.

If your PowerBook still crashes when you remove the memory stick, send a bug report to Apple with this information :

Apple Bug Reporter

Also, I would try to disconnect any non Apple hardware (mouse, printer, etc) and see if it helps...

Could also give details on when the kernal panics occur, if it's with specific apps or general.
If it happens with specific apps, remove the ram and test again. Could also create a new profile and see if the panics still occur. If not, and the memory test checks out, then it might be safe to backup and do a clean install in case something got hosed.
4 crashes in a month is very rare.

Well, this tells you a lot. Please remove all memory that you can remove and see if this happens again.

I don't think that an app caused this. If a badly written application accesses the wrong memory adress space the application would crash and the systems remains stable. So I would guess its memory hardware that causes the trouble.

Normally memory has 10 years of warranty. So the tip with the hardware test is a good one. But best is to find your receipt and return the memory with the hint to this exception and get it exchanged on warranty.

As everyone has said...

You almost certainly have bad RAM. This happens. It is not your "computer's fault."

On solid hardware with no system hacks installed, OS X is exceptionally stable. Your behavior is not normal.

This kind of stuff happens.

I bought my PowerMac G4 last year. I maxxed out the RAM to 2GB. Doing this revealed that I had a bad RAM slot. Apple replaced the motherboard under warranty. It has been running great since last February.

Good luck.

This is not a public access website. Only ADC members can access it.

Yeah, only ADC members can access it. You can sign up for the free account w/ your apple id and you can use it also
