Blue screen
After played during 10 minuts in the world, my computer has crashed down, I configured the game as follows:

I thought that maybe can be that my graphic card was overheated, but... I have two fans of 12cm in the side, 8cm fan on back and 12cm fan on front where are the hard disk drives, also the room temperature is less than 25ºC.

Has never happened with other PC games, so what thing can provoke the Blue Screen? I bought the computer on September 2010, so isn't too old for the game...

You cannot Alt+Tab from full screen mode in FFXIV...it was designed that way on purpose at an attempt to combat botters and hackers, but it has never worked and has only been an annoyance to we legit players.

A simple solution that I use is the Borderless Window Script

As for the GPU overheating...that is more than likely the issue as FFXIV is highly un-optimized and runs about 15-20 degree c higher than it should, thus ones GPU can overheat very quickly! Get yourself this nifty program EVGA Precision , course not sure if it'll work for a different brand of GPU, but don't see why it wouldn't. Anyway, with that program or another similar one, you can manually set your fan speed. Set it about 70-80% when playing XIV.

Try those options and see how it goes!
