Your screenshot indicates the HD Audio drivers that should be installed on your PC are no longer installed.
The best option is to uninstall the VB-audio cable drivers, then go to the support page for your PC on the manufacturers website to download and manually install the version of HD Audio drivers and Graphics drivers they provide.
If you have any difficulty locating that support page, click your Start Button, then just type msinfo and press Enter, please provide a screenshot of the resulting System Information window.
