Whenever I play certain games like Tera, Dishonored, Blade and soul, my pc crashes. The screen turns into a random color, and produces a loud stuttering sound, the fans go overdrive as well then suddenly stops, then I have to hard reboot the pc. I'm able to play Tera for a good few hours, but can't run dungeons, lowering the settings doesn't seem to solve the problem. As for dishonored, after the opening scene, it crashes. For blade and soul, it just crashes whenever I try to move while in a certain region, while in combat, and even crashes before loading into the game. changing settings doesn't solve the problem for all three games. I can run games like fallout 4, witcher 3, gta v and other demanding games without any problems. So far those 3 are the only games that crashes the pc.

I'm going to try and change the psu and graphics card sooner or later.
