There's only one memory dump in the folder - is that all that's in the folder on your computer?
If there are more, please upload them with your next post.
The lone dump file blames: xusb21.sys - a component of your XBox USB wireless controller
I would suggest uninstalling the program related to this component and see if that stops the BSOD's
