Hi, What’s the model of your motherboard? If it is too old and not compatible with Windows 7, some function may have problem. You can check it on Windows 7 Compatibility Center I suggest to update your BIOS to the latest version, also update your audio device. If the issue persists, you’d better contact motherboard manufacturer for further help. Hope that helps.
