This is what happens when I try to play the game: After 5 minutes (often less) of running around the Ul'Dah starting area, my screen turns black and the game crashes. A window pops up saying "Unable to detect DirectX device. The program has shut down. Please restart FINAL FANTASY XIV." In addition, my computer announces that "Display Driver NVIDIA Windows Mode Driver, Version 196. 91 stopped responding and has successfully recovered."

My system information:

Operating System: Windows 7, 64bit
Processor: Quad core 2,4 ghz
Memory: 8GB Kingston DDRII
Graphic Device: NVIDIA GeForce 9800 GT 1024 MB

I have installed direct x 9.0 c of the same cd of final fantasy XIV.

I've reinstalled my drivers and I've updated it too, and finally the error appears again. I need a solution please. Thank you
