I built my PC about 8 months ago and it's recently started auto restarting. Usually when in a game but not always. And it's gotten much more frequent. From all of my research and everything I've tried I've kinda narrowed it down to probably my PSU but maybe my GPU. I want to know the cheapest and least intrusive way to proceed.
