I have an amd fx 835o, gtx 970, 16 gb of ram, corsair rm 750and msi 970 gaming mobo. the computer boots and runs 2d apps fine, but when i start playing 3d games (accually running the game, not just in the menu) the computer freezes up, and the only way to stop it is to do a hard restart. this was happening before, but only on a specific game so i took it for granted.
