So when I’m gaming, my monitor loses signal however my pc keeps running. In order to fix the problem I have to restart my PC. I have tried replacing my GPU and PSU so it’s a pretty good assumption that it isn’t one of these two components causing the issue. Also to note, this happens more often when I am running a more powerful game, and it also happens more often on a hot day - to suggest that the stem of the problem is something to do with overheating. This problem has been ongoing for a long time so any help would be much appreciated.
