Mac 3,1 El Capitan randomly shuts down.

[fredfx]

Hi Forum:

My Mac 3,1 running El Capitan is randomly shutting down. I'm wondering is there a way or piece of software that can log what is causing the shutdown? Before I start replacing parts I want to have at least an educated guess as to what is causing these shutdowns.

My system config is below. I've also attached a .pdf of the crash reports following the shutdowns.

Thanks in advance for any help you might be able to offer.

best,

Fred
