Alienware R4 Crashing During Games/While Attempting to Run System Detect

I'm having a puzzling issue with my Alienware Aurora R4, recently updated from Windows 7 to 10. I've been playing a lot of Mad Max recently, and for no apparent reason, my computer has been crashing after about five minutes of playing. The whole thing just stops, no error message or black screen, just freezes in the game window. My video drivers are up to date (though it froze after restarting after installing the update). I have been forced power it off manually every time it crashes. I tried using Dell's system detect program in my browser, and when I use that it gets to something like "Obtaining System Diagnostics" and then hangs and I can move my cursor but all icons are unresponsive. If anyone has any idea how to resolve this I would greatly appreciate it.

Thanks
