Hi.
When i render the video about 3h long i render in HEVC 4k 60fps and especially if im doing upscaling from 1080p to 2160p this problem happens to me. It shuts down my pc after some percentage of render, more or less, every time percentage is different. But confusing part is that it doesnt shut down my pc completely. My monitor loses signal, also my keyboard and mouse stops working and my PC's ventilators start to spin faster and they became louder. So i cant shut down PC with keyboard, or mouse, neither the power button works on my pc case, only way is to kill the power for the PC. I dont like to shut down pc like that, its not good for it.
I also found old videos that people had problems when rendering shuts down their pc, but that videos are 6-11y ago recorded. In their solution is to disable half of the processor cores through "Task manager/Vegas/Set affinity". But i would like to use all off my cores, not half of them. I mean threads, not cores. Also i dont know is their pc is not shut down completely like mine, i found nobody that speaks about that on the web. So if you have idea what can fix my problem i would be grateful.
