Last night, I updated the onboard graphics driver, Intel HD 4600, and played for a couple hours thinking everything was fine. I log in today, and it again immediately crashes right after hitting play and nothing I do will appease it.

So, I'm not running anything in performance mode, it's not overheating at all and the GPU is fine. I couldn't say what my CPU performance is in-game, because I'm not able to get into the game at all, it crashes immediately after hitting 'play' on the launcher.
