New PC but unable to get realtek hd audio to work

New pc but unable to get realtek audio to work, it does not finish installation after restarting, like the installing window does not show up, realtek hd audio not showing in device manager
 
Computer specs which includes motherboard name and model number would help.
Which OS are you running by chance ?
 
First you will want to clear out the old driver attempt installation, if add/remove programs has realtek.
Uninstall it, then reboot once, then after that you download ccleaner.
Let it do one scan to fix any issues and clear out any registry screw ups.
