Hi,
No problem, try the following and let me know.
First, open windows Control Panel, open Programs and Features, right click the entry IDT Audio and select Uninstall.
When this has completed, restart the notebook.
Again, windows will load an audio driver automatically - just let this complete.
Click the Start Menu, open All Programs, open Accessories, right click the Command Prompt and select 'Run as Administrator'. In to the prompt type the following command and hit enter.
sfc /scannow ( note that there is a space between sfc and the / )
Let the process complete, then type exit and hit enter.
Restart the notebook again.
When windows has reloaded, use Recovery Manager to reinstall the original IDT HD Audio Driver ( this will also reinstall the Beats Audio interface ) - the procedure for using recovery manager to reinstall Software and Drivers is detailed in the document on the link below.
Recovery Manager - Windows 7.
After the reinstallation has completed, restart the notebook one last time - let Windows fully load for a couple of minutes before trying the Beats icon in the Taskbar.
Regards,
