My MacPro 4,1 is having nasty crashes, and I don't know why
So my MacPro 4,1, which has been firmware updated to a 5,1 so it is running OS X Sierra is having some nasty crashes, where I get this crazy video noise and the machine is basically locked up. I have to do a hard shutdown.
The system has 32GB of RAM and it's system is running of an OWC SSD in the a PCI Slot. It also has a USB 3 card, a Black Magic Intensity Pro and a PC NVIDIA GTX 670 with 4GB of RAM.
It started crashing in Premiere Pro, and DaVinci resolve so I thought it was video card related, but lately has been crashing at any time.
First I ran Cocktail and it's full suite of Automation. Then I restarted and ran Diskwarrior 5.0 from it's USB, but that didn't fix much if anything. And I upgraded to Tech Tool Pro 9 and ran it's full suite, and everything passed, including the video card (and I ran it's test a few more times). Strangely it ran longer while in the E-Drive than it has lately on it's own, which makes me think something with the system, and yet this looks like a very hardware centric crash.
And the system install is very recent, in the last 6 months it was a totally clean install.
Here is video of the crash:
I am just wondering if anyone else has seen anything like this? I am hoping it isn't hardware. Be it Video Card, motherboard or power supply, but it is getting so I can't do anything without a crash.
I have posted on the Apple Forums, and have one response.
I have looked at the console log and the files at ~/Library/Logs/DiagnosticReports/ and have not seen anything that would be causing this.
I do see that Expandrive is crashing all the time, which I know.
