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

When the game crashes, is there an error message that appears? If so, please provide a screenshot of the error message in your next reply. How long have you experienced this issue? Have there been any changes or updates made to the PC? Also please provide a system report. Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

Hope to see you online!
