PC restarting on window change



I have been having an issue since launch where if I alt tab, or just accidentally click on my second monitor with a window open then my computer will restart. I was wondering if anyone could help me with this, because I would rather not have to restart the game every time I want to alt tab, or restart my computer when I forget. I have never had this issue with any other games or with the beta, which so far I was able to put more time into since my computer was not restarting so frequently. So any help would be greatly appreciated.

Before you ask:
NO there is no blue screen.
NO there is no crash report (That I could find at least).
YES I have installed the latest graphics driver.
NO this did not happen in the beta or any other game.
YES Evolve is in windowed full screen mode.
NO I cannot give you a screenshot because my computer would have already restarted.

PC specs are:
8GB ddr3 RAM
GTX 780 TI
Dual 1600x900 monitor setup
