but some on internet saying the problem is because of this stwrt64.sys and Rtnic64.sys driver become old for windows 8.1. And required to update tht driver to become compatible with windows 8.1.

and when I google about the driver above. And stwrt64.sys driver is the High Definition Audio Driver. So try updating that audio driver and the rtnic64.sys is the Realtek driver. So problem is with them actually. So maybe the driver didnt found the hardware component or other related stuffs.
