Update your drivers and make sure you are actually plugged in to your GPU and not your motherboard.
yes, that's what I did. But let me make sure, how do you update your drivers? Windows update?
Nope that's for the OS. So to your Asus's or Nvidia's website (which ever brand you have) and look up the drivers for your model of GPU (ex. AMD: r9 280x, r9 290, etc; Nvidia: GTX760, GTX770, etc.)
