I have a new gtx 970m and just installed the drivers and got my Clevo P150EM to recognize the card. It is powered and appears in GPUz and afterburner but I can't run any of my games with it. Please help!
Reinstall the latest Nvidia drivers (344.75) and check the "clean install" button.
You didn't provide a whole lot of details, but I would guess that this is a problem with Optimus not kicking over to the 970M which should hopefully clear with a clean driver install.
