Unknown crashes

[EGT]

For some reason I've been getting a lot of crashes lately and I don't know what’s causing them. I don't mean application crashes, i mean that god awful black out of the screen and the "Hold down your power button to restart" ... whatever it is.

I know there is some way of looking up crash logs. Where can i find these and what should i look for to tell me where the problem is?

I haven't installed any new hardware since i bought RAM about 7 months ago so i don't think that's the problem. When it happened again tonight, i had just pressed "apple-shift-I" to import some photos to iPhoto. Other times it's happened just when listening to songs on iTunes. They froze in a short, continuous loop and then that ugly screen was staring at me ... so painful.

I'm thinking it might be something to do with having the iPod connected at the time through firewire (???) Other than that, i have no ideas.

Take that extra RAM out and see if it still happens. When OS X continuously crashes all of a sudden then its mostly likely a hardware problem. The easiest thing to start with is the RAM. Put in ONLY the stardard RAM.

I would also look at running the hardware test CD that came with your Mac. First though I would take out the RAM and see if that helps.

If you can make your OS run long enough, try repairing the permissions. I doubt that will help, but it never helps to trying little things like that.

the crash logs can be viewed using the console (Applications:Utilities). Once you're in the console, expand "/Library/Logs" and there should be a CrashReporter with all the logs of system crashes in it.

Otherwise you might want to Repair Permission and run the maintenance scripts. There is a good program called Onyx (freeware) that can take care of all things maintenance for you.

ok, i will try hardware test in the morning and also have a look at the crash logs.

I should have metioned that i have the latest version of Onyx but I've been using Macaroni to run the maintenance scripts etc so things should be running sweet.

thanks

I'm still getting these crashes I've just ran the extended hardware test and there seems to be no problems with memory or Logicboard etc.

Should just reinstall the OS from scratch?

1) What you described are kernel panics. Those logs are found on /Library/Logs/panics.log

2) The hardware test CD that apple gives you sucks. Try using an application like memtest to accurately test your memory. Let it run for along time.

3) Unplug all your peripherals except keyboard/mouse/monitor. If you're using a 3rd party mouse or keyboard, go back to the Apple ones. See if your kernel panics go away. If they do, add back peripherals one at a time and use the Mac until you find the culprit.

The panic logs show this:

Way over my head

Going to try memtest now, post the results later on or tomorrow.

The only peripherals i have connected are an ISDN USD Adaptor and a set of speakers. I just use the powerbooks keyboard and trackpad.

Thanks for helping out.

ANd then mention of the apple USB driver.

Looks to me like your USB ADSL modem is the culprit, assuming that's what the draytek thing is all about.

Phew! I was thinking that it was something more serious for a while. You've made my day! Thanks for the help!!!

the crash logs can be viewed using the console (Applications:Utilities). Once you're in the console, expand "/Library/Logs" and there should be a CrashReporter with all the logs of system crashes in it.

Otherwise you might want to Repair Permission and run the maintenance scripts. There is a good program called Onyx (freeware) that can take care of all things maintenance for you.

sorry I'm kinda new to Mac can you point me how to get there (crash logs) exactly. I tried to locate Library/Logs under Applications but wasn't able to.

TIA
