I am having the same problem, i updated to Windows 10 and now it crashes my PC, makes it restart but not a full restart like if it was over heating. But before this Arma 3 ran just fine, when i had Windows 8.1. Now the game crashes my PC, and i don't know why.

When I start it the 1st time, I get that, but the next time I start it, it restarts my PC.

Oh, and PlanetSide 2 does the same thing now as well, work just fine on Windows 8.1. And i re-downloaded both games and still the same thing.
