This problem has been happening to me for a couple of days now. When I'm playing a game, my system will restart during specific times. There is no bluescreen or error code (other than the event viewer, but more on that later). It seems to happen when I am transitioning between menus or loading something. It happened first when I was playing The Witcher 3 and I would load a previous save or fast travel. It also happens in Overwatch when the map gets loaded. It has also happened when I'm alt tabbing out of a game, but this is a rarer occurrence. I thought at first it might have been a RAM issue, so I removed one of my 8GB sticks and kept one in. When it crashed, I swapped sticks but it crashed again. Then I thought it might be a GPU issue, so I ran a stress test but it never crashed. My HDD and SSD also passed their respective tests. The thought occurred to me that the most obvious culprit would be the psu, but I have no idea how to test this other than swapping it out with another one of the same or higher wattage, but I do not own another as this was my first build. I ran AdwCleaner and MalwareBytes on the off chance it was some sort of malware but they came up clean. The event viewer tells me the source of the error is "Kernel-Power, Event ID 41, Task Category (63), Keywords (70368744177664),(2)." Googling this gave me no new ideas so I figure I'd ask the friendly people of Tom's Hardware for some ideas. I've added a link to all of my hardware below. Thanks for any suggestions.
