Hello,
been having some issues for a while with FFXIV causing my pc to entirely crash and become unresponsive. The screen(s) either go completely black and/or upon restart one of the screens has a large white bar across it with a few random dots above and below.

This doesn't happen to me in any other games, not even heavier ones such as the Witcher 3.

Reinstalling my graphics drivers seems to solve the issue everytime but then upon playing again, after not very long I receive the same crash. It doesn't happen during any particular time, not cutscenes or battles or anything in particular; nothing seems to trigger it. I have a feeling it must be to do with my drivers or DirectX?

I have an NVIDIA GTX 970 (I have done a complete fresh install of the drivers a few times already). I have also tried to resit the card.

Please help!
