I would say that its more likely to be an instability in the os or drivers or hardware. I would suggest either to update or roll back gpu drivers if you have recently updated them or if they have been updated by windows update. Make sure your laptop is not overheating if you over clocking the gpu ir cpu then you should return the clock back to the base clock. stop codes can be notoriously difficult to fault find.

If you've not already done so then it's worth testing it with 3D mark (the free one) and something like Prime95 blend mode to see if they also make it fall over. Checking the CPU and GPU temperature readings while playing might also give clues.
