So I've just built my first PC ever. Pretty excited about it. It actually posts and runs smoothly at first glance. I start to download all of my games and what not onto it overnight and go to bed. So the next day I go to play League of Legends, a relatively low demand game and use OBS to record the gameplay just as a test. About ten to fifteen minutes in, the computer freezes completely, requiring a hard power off and reboot. This phenomenon continues during gaming, whether it be League, BF4, 7 Days, anything requiring moderate load. However, just browsing, it's never frozen. I've updated drivers, everything I can think of to no avail. Please help.
