Computer reboots a few seconds after launching the game.

Hmm. What processor do you have? Amount of RAM? What are the "other" games that work "just fine"? A patch by SE likely wouldn't do you any good. If your computer is just shutting off, there's more than likely a hardware issue somewhere.

Intel Core i7-3770@3.40 GHz with 16 GB RAM. Other games I've played recently, without problems, are Hitman Absolution, StarCraft 2, Dota 2, Mass Effect 3.. etc. Maybe they're not as demanding but changing the graphic settings in FF ARR doesn't seem to help. (A few times I've been fast enough to change the settings before computer reboots.) I'm gonna try stress testing the computer to see if it shuts down. And try again after the maintenance tomorrow. Just to make sure.
