Problems occured after a complete reinstall of Windows 10 OS

I need to reinstall driver for my internal Bluetooth adaptor on each reboot of the laptop in order for the bluetooth to find my devices for connection. I have tried all versions of drivers from 2014 until the latest 2019 - and it doesnt matter which driver I reinstall after reboot, it works fine with any. But after reboot of the PC no devices can be found and a new reinstall must be done again. The Bluettoh adaptor is Qualcomm Atheros AR3012 Bluetooth 4.0, PC is ASUS Transformer book TX300CA. I have run troubleshooter, restarted Bluetooth services, running systems scans in the Commander and a bunch of other suggestions on this and other forums. Worth mention is also that if the bluetooth device shuts down, during same PC power-on session, in order to find device it must be marked as forgotten in settings and make a full reconnection again. Sometimes the system cannot detect what kind of device it is, meaning a speaker would not transmit any sound. A fix would be higly appreciated.
