Since last week, I've experienced about 10 kernel panics. It all began when I was using Google Earth when the fans starting going crazy, then bam - it powers off. Then at various other times it would shut off, like when I was watching a movie or using iChat. Now, whenever it shuts off and I press the power button to turn it back on, it shuts of immediately afterward (I don't even see the apple logo). I was using 3rd party RAM, and thinking that was the problem, I removed it and installed the stock ram even though memtest said it was ok. But since removing it I've had 3 kernel panics, which were all today! I ran memtest again and it said everything was ok. What could be the problem with it? Are there any fixes I can perform myself without having to take it in?

the only third party thing I have attached is my HP printer, and it wasn't even attached the first time I experienced a kernel panic. and I just ran disk utility and it said it was ok. :confused:

It just happened again and I've noticed that it's happened 4x while using iEatBrains (used to find information on songs in iTunes library). Should I just take it up to the apple store, or is there a way to fix this myself?

I have had 9 kernel panics today. yah it sucks. at about the 7th i figured out it happened when i was playing wow at full settings. I cranked wow down bit by bit to get it stable and i havent had one for a few hours. I also had a kernel panic when doing some h.264 encoding on my old mb. I'm guessing the mb and mbp start having coruption issues when under lots of stress and heat, which leads to the grey screen of death.

ps. I have have run the hardware test, everything good. and the reparied permissions. if i get another outbreak i'm reinstalling osx, then im returning it doesn't work.

Generally speaking a Mac will fall asleep before it kernel panics from overheating, but both of you might want to use CoreDuoTemp or something similar to monitor the temperature. Make sure your machines are in a well ventilated area too, and use them on a hard, flat surface. :)

Ok, I have had and are having the same problem with my iMac G5.

Im getting a couple of Kernel Panics per day on average. I have done all the things you can do yourself and had to logic board replacements. If you take your Mac in I suspect they will do the same but this has not fixed the problem.

Also check out your panic.log file (you can open /Library/Logs/panic.log from /Applications/Utilities/Console) for any information as it can clue you in what is triggering the panic.

Memory related issues may look something like:

USB related panics tend to look like:

.. and so on. The above isn't all inclusive as the messages can vary greatly. I remember when my processor was the culprit (but unbeknownst to me at the time), it just spit out something small like this constantly and even engineers couldn't figure out what the problem was:

panic(cpu 0): thread_invoke: preemption_level -1

and when it finally fried completely, the dreaded "machine check exception" (fatal unrecoverable hardware problem):

Wow, I have owned 3 macs, and I have only been through 2 Kernel Panics. Once on my PowerBook and once on my MacBook Pro. You should definitaly get it checked out.

I cannot find this panic.log. Spotlight couldn't either.

Hmm... Are your kernel panics showing the grey screen? I don't have the panic log either but I think that's because I haven't had any kernel panics. Have you cleaned your logs (maintenance tasks do this) since the last kernel panic or reset your PRAM? :)

Yeah I reset the PRAM and it hasnt happened since then....but that could just be coincidence since I havnt done any processor-intensive things. ill test it when i get back from class...but now I have a test to take :(

Okay, well resetting your PRAM will have cleared your logs. I mentioned it more for pknz as a possible reason for not being able to find panic.log. Good luck with your test. :)

ok well I just ran iEatBrainz and that definitely did the trick....yep....another kernel panic. it does it with both the stock ram and the 3rd party ram (omni ram). so im guessing i have to take it in? :( if it means i have to give up my computer for a week then forget it....I'll just live with it....

I've been having the same problems with my iMac G5, its's gone in for repair, and the logic board needs replacing. I took a photo of what was happening to it with my digital camera to show to the repairers. I'm not sure if they are related in any way though.

Good luck with it. Hopefully they'll be able to fix it promptly.


Amy2005, at first glance your kernel panic looks to be from bad RAM. Do you have third party RAM? If so, are you comfortable taking it out and testing your machine with it not installed? :)

I love the last line of the ol' kernel panic screen. Gets me every time. :D

When i bought my mac from a shop i had extra ram put in yeah. Its gone there to get repaired and they say it needs a new logic board, i'm ringing up tomorrow to see if its ok, so they may say something about the RAM then. :)

The last line scared me at first, then i thought it was funny lol :)

Ok latest call to Apple (in Australia) resulted in them telling me to take it back into Apple (in New Zealand) and have their technicians get in contact with the Australian technicians over this problem...

Wonder what will come of it this time.

Which means I'll lose the iMac for a week or more and my sister has university assignments and I have secondary school assignments.

Just give me a freaking new one already!:p

i took it to my apple store the other day and they said they would have to replace the logic board and heat sink (and the part of the case that's changing color). they said it would take about 4 days at the apple store....so I'm gonna have to wait for a week when I don't have a paper due to give it to them. but the situation has gotten worse. whenever i turn on my macbook, a dark grey screen appears with multi-colored vertical lines.

I'm glad that yor machine is still under warranty.

Generally if a machine has a problem, it will show up before your warranty has expired.

Unfortunately, these inconveniences are the pitfalls of buying Rev "A "
machines from just about any manufacturer.
