Unfortunately, it isn't just those with Nvidia graphics cards that are being affected by this. I use an AMD Radeon HD 6700 graphics card, and I am also having this problem. My whole computer will restart after a few moments of logging in to FFXIV, and this has only started happening yesterday. I haven't had any problems with it randomly crashing in the past, and now it is suddenly crashing every time I log in. I've checked all potential problem parts on my comp, but they are all running smoothly. All of my other games still work normally, too. It is just FFXIV that is giving me trouble.
