So I've been having this problem for the past few weeks. Sometimes, even when I'm running stock, my PC stops displaying outright, the fans still work, the aio pump still works, everything works, just the monitor screen goes black and looses connection. The only thing that does stop is sound, so I know it must be a hard crash of some sort. I checked if it was the gpu but it wasn't. A light located to the close left side of the dim slots starts blinking orange (long orange light with short pauses) I couldn't find anything online on this issue.
