I tried multiple times, and it just reboots every time, can't get past the very beginning of the campaign without it causing my computer to reboot.

Tried "Verify Integrity of Game Cache" in Steam Local Files tab.

Just played almost 3 hours of Battlefield 4 with no problems today.

Other games I have installed that have no issue are the new Doom, Elite Dangerous, XCOM 2, Civilization V, Wolfenstein the New Order, and FarCry Primal. All these games run Flawless.

Don't believe it to be a hardware problem.
