I have been having an issue with my machine for the past few weeks. Every time I run a game on my machine what uses DirectX11, the game crashes after about 20 minutes of it being played. It only happens to games that are using DirectX11, (anything but DirectX9/10 etc.) It happens to games such as: TitanFall, Metro: Last Light, Far Cry 3, Bioshock Infinite, and Battlefield 4. Other games such as L.A. Noire, TF2, Portal 2, Garry's Mod, and Orcs Must Die 2, work perfectly fine. I have tried a number of things so far to attempt to fix this issue such as: running the program as administrator, checking for updates on all of my drivers, reinstalling drivers, and turning ups fan speeds. None of these have worked for me. Please help.
