BSOD is making it impossible to play
I'm having similar problems and I've tried many of the solutions suggested but nothing seems to work. What happened to me was that I was getting BlackSOD from time to time but now I can't get past a particular cutscene because each time my computer crashes. It seems like my computer handled other more graphically intensive moments during the game but can not get past this one cutscene.
I have never had this problem before and I've played recent games on high settings. I can understand it's maybe a hardware problem but it's FFXIV that is the cause of that problem. I would just love to know which aspect of the game is causing this situation for so many people.
Sidenote... I have an open ticket with no response yet. Someone already said they had one open for 5 days so I'm not holding my breath.
