Some tips to try:
1) Go into device manager and disable (not uninstall) all the Nvidia HD audio driver's.
2) 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.
3) GPU overclocking - in case the GPU is overclocked, try to lower GPU and Memory clock speed (Perfomance Tab for NVidia control panel)
