My video card has been working for a few months. Both in this setup, ( R7 2700X) and in my last CPU ( i7 4790). For no apparent reason, it started turning off while idle.
All my drivers are up to date. The BIOS and Chipset are also updated.
It also happened once during a Linux distro installation. ( My PC is currently booted to Linux, for testing reasons ).
At first, on windows, I had MSI Afterburner configured with a custom aggressive Fan Curve. Since this problems first started, I disabled it, and tested the Wattman Power Saver profile. It turned off while I wasn't even touching the PC.
Here is a picture of it. I can confirm that the Fan is blowing.
[EDIT 2 -- IN THIS PICTURE: PC is on, (sound is on), video-card leds and Fan are on, but the tachometer is showing no activity + there is no signal in the monitor ]
The two 8 Pin connectors do not share the same cable. This power supply a 80 Plus Bronze certificated PSU.
Here is a picture of it's specs:
There is no Overclock in place, and was not under pressure in any of the situations that it crashed.
Any help ?
I have worked in this computer using Linux for a whole day, and nothing happened.
