Also having this issue. However, I don't even get a BSoD on my rig; the computer just powers right off, then a few seconds later, boots back up. No error, nothing.

I have been playing this game for months without issue. Nothing changed over the past few days that I can think of, no updates applied, no hardware changes. All of a sudden, I was playing for a couple hours the other night, and the computer rebooted.

I have checked/tried:
- All temperatures (system is watercooled, nothing above 50C)
- Power supply (750W)
- Video card drivers (Geforce 660ti)
- Reinstalled FF14
- Prime95 (passed, 14hrs+)
- Memtest 86 (passed)
- MSI Kombuster (14 hrs+)
- Low graphic settings
- Upping GFX voltage, lowering clock speeds

I am completely stuck at this point. I know my hardware is fine given all the stress testing I completed. I tried rolling back the nVidia drivers, still same issue. The game will load to character selection but as soon as I select a character and the screen finishes loading, computer powers down. If I then reset to default graphic settings (play in a Window), sometimes it crashes right away, sometimes I can play for 15 minutes before it happens again.

I will note that I can play ANY other game, like Farcry 3, Starcraft II, Counterstrike GO, without issue, for many hours. It is ONLY this game that will do this. There has to be some software/driver conflict going on because I have now read countless posts with the same/similar issue. Clearly this frustrating because I see no solution in sight. It is so hard to troubleshoot since I get no error reports of any kind. I'd hate to have to nuke and pave the OS and not have that resolve the issue.

Currently resorted to playing on a crappy laptop until someone can produce a permanent solution. Any further suggestions are always welcome
