Game crashes with no warning

[Rhaervis]

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

We would also like to recommend several other troubleshooting steps:

1) Make sure that your hardware is not overheating and remove any overclocks you may have on your graphics card or processor. Please check that any fans or vents are clear of blocks.
2) Disable any additional programs that could cause interference with the game itself including chat programs. Also, remove any custom configurations made using graphics driver-level programs
3) Remove any mods or injectors from the game or system
4) Turn off Fullscreen Optimizations. Find the executable file for the game (normally found in the install folder), right-click it and select 'Properties'. Under the 'Compatibility' tab, check the box labeled 'Disable Fullscreen Optimizations', then click 'Apply'.
5) Remove any unnecessary USB or audio devices (controllers, headphones, flash drives etc.)
6) Reinstall the drivers for your graphics card
7) Perform a clean boot by opening the task manager and select the 'Start up' Tab. Disable everything

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

Hi Rhaervis,

thanks for your answer. I googled and read several threads before posting, so I nearly did every Task you recommended before.

1) I have checked and monitored it while starting the game.
2)I disabled everything that I could. Which also includes all Statuptasks 7) I made a clean boot without any startups that I could disable. I literally had only ff14 and windows based Programs running
3)Never used one. If there are built in things then I don´t know them.
4)I will try this again due to the fact that there are several exe Files and I just did it with ffxivboot.exe
5)I started with everything unplugged exluding Keyboard etc.
6)I reinstalled the whole driver but it didn´t changed anything
7)see 2)

Many thanks for your help
