Black sceen render issue?

hi all ! im having an issue where every time i go to render its just a black screen ?? anyone know how to fix it ? thanks.

im running a RTX 2070 razer laptop

Render with what?

i think i found a solution i turned RTX of and switched to CUDA and that seemed to of done the job (Vray)

Moved to the Vray category since this is related to Vray.
