You uploaded your WatchDog (WD) memory dump which isn't a real BSOD. The error was 0x117 which isn't a "real" bugcheck
Bug Check 0x117: VIDEO_TDR_TIMEOUT_DETECTED

Did you recently update your video drivers?

Check to make sure your card isn't overheating. Use a program like GPU-Z to monitor the temps GPU-Z Video card GPU Information Utility. Also make sure that your video card fans are working properly.
