^ As above are you using a desktop or a laptop, Could be un-configured switchable graphics, Find the name of your card(eg GTX 660) and find the latest drivers also check the device manager to see if it's actually installed.
right click on your desktop and go to Nvidia control panel.
then set graphics settings to 'global'.
that'll enable EVERYTHING you run to be using the Nvidia card instead of the Intel HD card.
