Crashing A lot

I'm getting pretty frustrated with the crashing issues that i'm experiencing. They are very common. The game runs perfectly fine otherwise, smooth performance with all of the graphic settings set to standard. FFXIV will just randomly crash to desktop, with no error message, just that it has stopped responding. :(

Here are my system specs:

Tried to reinstall the game and errorchecking your harddrive?

Might be a file corruption issue.
Get a md5 filechecker (for example this one) and verify your files.
