A few days ago I noticed Geforce experience had PUBG listed as being able to be optimized so I decided to go for it. About 10 minutes in game my computer hard crashed. Pressing the power button would not turn it back on and only flipping the psu switch on and off would boot the computer. CPU temps were hovering around 45 C and GPU was mid to high 70's. The crash does not happen when reverting to my previous settings. Playing with the settings to try to fix it, I put everything on the lowest setting and turn certain settings up. Anti-aliasing and post processing were the ones that made the computer crash. Could this be a GPU or PSU problem? GPU temps seem fine and shouldnt crash the game.

CPU: FX 8320
