Hi:

 

You need these drivers for those devices...

 

SMBus Controller:

 

This package contains the Intel Chipset Installation Utility. This utility enables the operating system to show the correct name for the installed Intel hardware in the Microsoft Windows Device Manager. This package is provided for supported computer models running a supported operating system.

Bluetooth:

 

This package contains the driver installation package for the Mediatek Bluetooth in the supported notebook models running a supported operating system.

The Mediatek/Ralink bluetooth is not supported on the newer builds of W10.

 

That is why it doesn't work.

 

Nothing you can do but to replace the Ralink wifi card with a different model, or buy an external USB Bluetooth adapter.

 

If you want to replace the wifi card I will need to know the product number of your notebook.

 

Use this guide to find the product number of your notebook...please do not post the serial number.
