Can somebody help me with interpreting kernel panic, please?

[putinga]

Hello folks,

Recently, my G4 1.67 started experiencing kernel panics. It started from ordinary bad ram symptoms - 2 or chims on startup... everything was backing to normal after resitting the modules (for up to five days)

I have tried clean system reinstalling (with zeroing) and everything from 'resolving kernel panic' document....

now, can someone savvy look at this:

Sorry for the grammar, guys. I am just waked up and it is not my first language

Why don't you run AHT (Apple Hardware Test) on your computer?Maybe it will tell you something...
Download here: http://www.info.apple.com/support/aht.html

That info and some more in FAQ on my sig.

hi skinniezinho,

i have used AHT and it says either, that two slots and two chips are running smoothly, or one RAM chip is missing. I will run it once again and share the results.

Anyway, thanks for your reply, skinniezinho.

Regards,

Well try running your computer for some time with only one slot, then the other...
To find out if you have some bad ram.
For example I had 4 dimms, everything went fine but sometimes I had kernel panics, turns out that it was one stick.with that stick only the computer wouldn't even boot!with 4 it was ok for lot's of time..
