Q: Kernel panic

Hello,

 

I have a late-2009 MacBook A1342, which started giving me trouble in 2013. I shelved it at that point but now I am trying to repair it.

 

I was getting kernel panic errors during OS boot (Mac OS 10k549). I removed one RAM module, and it worked like a charm. Put the module back, it worked fine. Ran system updates, rebooted, and then I had my kernel errors again.

 

Sometimes, instead of the kernel panic screen, I would get the "your computer restarted because of an error - please press any key to continue or wait for a few moments' screen.

 

I would sometimes even get a kernel error while loading OS installation from a USB drive, with the HDD unplugged. Installed OS X Yosemite to an external drive, and am getting kernel panic on boot from said drive.

 

Ran memtest86 on both modules, after almost 3 hours of testing and 4 full passes, there were no errors.

 

Repartitioned the main HDD, installed Yosemite 10.10 successfully (it would not install prior to the re-partition, installation would hang and then display kernel panic after quite a while), and it still won't boot - gives me the 'your computer was restarted' message.

 

Fiddled around with RAM module placement, no joy. This seems to me like a RAM or logic board issue, but it would be one **** of a coincidence for both modules to have gone foul at the same time.

 

Here is a shot of one of the kernel panics.

Any help would be highly appreciated.
