This sort of message is generally not from Windows, but from an audio manager program that was supplied with your sound card (whether that's integrated in the computer or was a plug-in card inside a desktop case). Check out what's running in your system tray, including the overflow area, and you'll likely find something like RealTek Audio Manager, or DTS Audio Control, or similar. You can typically bring up the context menu for same and through their settings set them not to start with Windows or to turn off selected or all notifications from them.
It's impossible to get more specific without knowing specifically what's running.

Always remember that computers are just glorified light bulbs - they rarely fail in continuous use and usually go pop when turned off and on.
