All of my games (PUBG, Darkest Dungeon, and Hearthstone) will work fine for an hour or so and then eventually crash with no error message. When I reopen the games they only stay open for a few minutes before crashing again. Google Chrome has an issue which causes my screen to go black for a few seconds, and if there is a video playing it will stay black with a green box in it (image provided). These issues started happening when I got my new cpu, mobo, and ram. I originally thought it was a gpu issue, because overwatch would crash and say "rendering device lost", but I recently replaced my gtx 950. I am now leaning more towards RAM, because one of my sticks can only go up to 2866mhz. I already wiped my harddrive and fresh installed windows. I just want a second opinion before I replace anything.
