Mac Pro 3,1 Random Shutdown Problem

#1
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.

And of course....like many of you out there, I'd love to replace it with a new Mac Pro..........but alas.....there isn't one....

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

best,

Fred

Some questions:
What are you running when it shuts down?
Is the machine running hot? Check the vents to make sure they are clear of those dust bunnies. Once it cools down, open the machine and check the fans to make sure there is not dust slowing it down.

What devices do you have plugged in and running?
