Random Kernal Errors - Enough already!

Question

Random Kernal Errors - Enough already!

Ok.. i just can't take it anymore. I have for years now been getting random Kernal errors where my screen suddenly scrolls grey and then the fan goes haywire. Sometimes i get a transparent black screen where all sorts of gibberish (to me anyways) shows up saying there was some panic error and all sorts of data... and my computer freezes. Sometimes i wake up in the morning and the computer is already frozen and the fan is in full jet plane mode.

This has been going on for years so it is not a just a OS 10.5 issue, but i am noticing it is happening more and more often, sometimes as many as 3 times in a day versus once every other week or so... it just seems like it is getting more and more frequent.

I have run Applejack, memtest, disk repair, repaired permissions, reset PRAM, and everything says there are no problems. I bought the computer used maybe 7 years ago and never had the original system discs so i can't run a real diagnostics on the computer. It is a dual 2.3 G5. I have tried taking out each of the extra RAM but it doesn't seem to matter. I am so used to it that i just reboot and move on...but I am getting really annoyed.

here is one of the reports i saved... maybe someone can make sense of it?

I would try running the extended version of your Apple Hardware Test.
It's not perfect but may flag something. Or, do you not have that disk?

You are experiencing a Kernel Panic as seen and described in Apple doc.#106227. If not, disregard.

Bad or incompatible RAM is the most common cause of KP's. It could just need to be reset……. to make sure there's a good connection.

Here's a great site for Resolving Kernel Panics. Please do all the steps in order, even if you don't think you need to do a certain step.

Here's a great MacFixIt article.

It also may be time to invest in a good disk utility.

If Disk Utility can't fix it, you'll need a more robust utility for the repair. I would recommend DiskWarrior. It is the best at directory repairs. It rebuilds then actually replaces your old directory. I feel every Mac owner should have a copy.

Make sure you get the disk so you can boot up on it to run repairs. You can also install it on another drive and run it from there to repair this one. DW works faster that way.

I use DW once a month to try and catch errors in my system from getting too far out of hand.

 Good Luck! DALE
