It's happened to me a few times, re-installing the official iGPU drivers from Intel or Nvidia drivers does the trick for me.

Im still struggling with this, I tried reinstalling the Nvidia drivers but no luck!

I have resolved it, going here and updating a load of drivers : http://www.drivertoolkit.com/

It's quite likely that you'll experience some bsods after using that driver tool. They're incredibly unreliable and often install incompatible drivers leading to instability. If you have further problems, let us know.

I reverted to Windows 8.1 on my Optimus IV, there were just too many little issues with Windows 10 to make it a stable platform.
