Hi Richard,
It could be your Asus bluetooth managing app set to automatically run on very Windows startup. Can you send us a screenshot?
For now, try disabling it by following the steps in this article. On Step 6, look for any Bluetooth services, select it then click Disable. Give it a try.
If you continue to have this issue even after performing the steps in the article, please reply to this thread. The system will notify me so I can get back to you and provide you more answers.
