sudden crash with no message
mac pro (start 2008) - el capitain 10,11,6
hello my mac pro crashes up to three times in the morning. No message on the screen, black screen and the fans start spinning fast. I wrote "crash" in the console and this is what it says. Answer me in French if possible thank you
