Question / Help Black Screen on Windows 10 Desktop

[Aquariphone]

Hi there! I'm running Win10 64-bit. My machine has an Nvidia card but no other video processor (e.g. Intel chip). Is there any way I can get OBS to capture my screen? Audio seems to be working fine. Thanks very much for your thoughts!
