Hi xmage,
The sole minidump file isn't terribly helpful, but it does provide a jumping off point: the given process name is "GameOverlayUI'. If you have NVidia Shadowplay, Plays.TV, Discord, Raptr, etc, running with an overlay, try disabling it and see if you encounter the same issue.
It also looks like your CPU is overclocked, and the BSoD that is listed is a 0x101, which is commonly caused by overclocking.
Code:
[Processor Information (Type 4) - Length 48 - Handle 0041h]
Socket Designation U3E1
Processor Type Central Processor
Processor Family cdh - Specification Reserved

You likely need to increase the VCORE (CPU voltage), but for the purposes of troubleshooting, return to the intended clock speed of 2.7GHz.
