It seems to be just FFXIV:ARR that is doing this to my PC and it is at random times. Sometimes it is a few minutes in or sometimes it is immediate.

I am just running around questing or doing fates or whatever and then all of a sudden the screen goes black and there is a buzzing sound and either I am forced to reboot the PC or it does it itself.

Sometimes I get this message when windows tries to boot up it says: "An operating system wasn't found. Try disconnecting any drives that don't contain an operating system."

I do have 2 hard drives hooked up to my motherboard, but so far (knock on wood) when I play Battlefield 4 or other games this issue does not occur, just FFX14.

Is anyone else experiencing this? And if so, what can I do to get this to stop?
