I just upgraded my system to Windows 8.1, and I have been getting BSODs that I did not get before the 8.1 upgrade. Though I cannot conclude that running the Android Emulator with Intel's HAXM is the cause, both crashes have occurred while the emulator was running.
Output of verifier.exe /all and then a reboot and then verifier /query: http://sdrv.ms/17CPVu9
Edit: According to http://software.intel.com/en-us/forums/topic/475129 it is being caused by HAXM. Will close question when I find a solution.
