Some tips to try too:
1) Go to grahpics options and make a frame limit to either 30 or 15 (check 30 first).
2) Go into device manager and disable (not uninstall) all the Nvidia HD audio driver's in case it is Nvidia GPU.
3) GPU temperature - please check while playing the game gpu temperature with a program like GPU-Z, to make sure GPU does not overheating. If it does, try to turn on FPS limit to 30 FPS in graphics settings.
4) GPU overclocking - in case the GPU is overclocked, try to lower GPU and Memory clock speed (Perfomance Tab for NVidia control panel)
