Exact same error message. Only I'm on Windows 10 Home 64bit 1607 version (recently updated) with a brand new laptop:
AMD A10-9600P Quad Core
Ati Radeon R8 M445DX
8GB DDR4 RAM
My trouble also started out of the blue. PC crashes, no BSOD, just reboot and then continues like nothing happens. Here is the minidump: https://we.tl/CtN5HbVioP
More notes: all display drivers up-to-date, so are all Windows updates.
I've seen some messages that this could be due to low voltage in the kernel, which would cause it to malfunction. The claim that this would be from overheating seems unplausible to me, as the PC is (literally) a week old. And I haven't been doing anything intensive for the hardware, yet.
