Hi everyone again,
I have exactly the same problem like some users around the world. For example -
https://community.amd.com/thread/236638 The man from the AMD community described the problem in detail. I can´t find any solution of the problem with PC crash black screen. When I say "Crash", I mean the screen goes black and there is no image on screen. The keyboard doesn't work. Even the power or reset buttons don't work - I have to remove the power cord and re-plug it in physically. There is no bluescreen or anything. It just stops working. The log of events simply shows that the previous shutdown at <time> was unexpected.
I've tried everything, absolutely everything. It means update all drivers, bios, windows etc., change MTB, VGA, RAM, power source.... My computer with AMD 2990WX is 100% stable (a lot of synthetic tests, Vray- 100hours stable rendering etc.) except of the situation when I am using Corona render. After a few minutes or hours PC crashes.
Please, is there anybody here who have experienced the same problem and found any solution of it?
I'm really desperate...
