Delete the steamvr.vrsettings file in "C:Steamconfig" (replace C with your drive letter). Then uninstall SteamVR and re-install. Go into Nvidia control panel, manage 3d settings, program settings, add all of the SteamVR apps (Compositor, Server) and set them to use your dedicated graphics card instead of the integrated graphics card.
