Hey,
sorry I couldn't get to you as I got quite busy during the weekend.
Anyway I did run a log to GPU-Z -
http://www.filedropper.com/gpu-zsensorlogI did a complete gpu-driver uninstall through DDU and then updated to the newest drivers (xxx81).
What's weird about the last simulation: it was running smoothly for a 'surprising extended amount of time' - I then closed the simulation and went watching videos on youtube right after and then "BOOM, headshot": laptop shut itself down.
Any clues?
I guess my option is to try up-/downgrade to either 670MX or worst case scenario or 660M
edit: I'll just make it clear that I can browse and watch videos fine, but apparently not right after a 'simulation' - I can even play old games like WipeoutXL/ 2097 continuously..
