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

You mentioned this is a new PC, correct? Double-check that you have all of the 'Optional' and 'Recommended' updates for Windows 10 installed. These may not be installed even if it says it's up to date.

When does this happen? Is it when you first log into the game or while you are playing?

Can you submit a Final Fantasy XIV system report? Simply go to the 'Config' option on the Final Fantasy XIV launcher and to the right of 'System Information' click on 'Display.'

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