10.6.8 freezes periodically on MBP 3,1

Even though you've given us a good bit of infomation about your setup, you really haven't given enough about your issues.

You mentioned freezes and crashes. Can you post a "hang" or "crash" report in order to home in on what the computer was doing at these times please.

Also download and run EtreCheck to give us an even better idea of your setup. I realize it's for Lion and above, but should report at least some useful information to you. Copy and paste the results back here.

Have you run the Apple Hardware Test - either from the HD, or an original install DVD ?.

TG0D is for Logic board GPU Die temperature, so far as I'm aware, although that model's book shows all these : TC0D, TC0P, TG0P, TG0T, TG0D, Th0H as 'Main logic board'

Fan sensors are TG0H & Th2H.

While the fans or cooling may be at fault, I'd say that the code suggests a problem with the graphics chip, possibly caused by poor cooling, However, the disk0s2: media is not present. does seem like a drive issue... do you have an external to boot from or one to replace it with ?.

andyBall_uk, greetings; Would you be kind enough to share with me the source of the AHT error codes. Thank you.

Ciao.

Hello Oglethorpe, I've chanced upon several different ones, although posting links here could be against the rules... hopefully you'll find something with a search, or I can show an email here.

Hi Ogelthorpe

I see that some Apple Hardware test files include a list of codes, and since that isn't part of a confidential Apple service document, there seems no reason that the lists can't be shared .

Here's an example list, from an F42388C8 test. Look for an Fnumber.tdf file on any other machines.
