Good morning! Thank you for posting in the Final Fantasy XIV Technical Support Forums.

Please try the following:
- Update and reinstall the drivers for your graphics card and sound drivers (if applicable).
- Please try lowering the resolution.
- Please try running the game as an administrator.
- Perform a clean boot by opening the task manager and select the 'Start up' Tab. Disable everything.
- Please be sure that Final Fantasy XIV is installed to the C: Drive. (If Steam version, make sure both the game and Steam are installed on same drive)
- Please be sure to disable or remove any overlays (Discord, Steam, NVIDIA etc.) as they may interfere with startup.
- Make sure that the Windows OS is fully updated.
- Verify installation files (Steam)
- Reinstall game (If steam version, try uninstalling and reinstalling both the game and Steam). When reinstalling, please make sure to delete the locally saved content ('Documents' > 'My Games' folder).
