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

Outside of recommending to lower any settings, and making sure that the hardware is clean, there is not much I am able to suggest. As the issue you are describing could be a hardware problem, I advise to speak with someone who would be able to look at your PC physically.

This thread will be moved to ‘Separate Support Required’.

Thank you for visiting the Final Fantasy XIV Technical Support Forums.
