Good morning and thank you for posting on the Final Fantasy XIV Technical Support Forums.

When did this start occurring? Was there any change in your PC that coincides with the error? Do you notice any pattern to the crashes, or does it seem random?

To resolve the issue, you can try updating your graphics card drivers and disabling any overlays that are active when you play the game (such as the Steam overlay, Nvidia Geforce, etc.).

We hope we can be of assistance in helping you enjoy the exciting world of Final Fantasy XIV!
