Windows 10: Sound, wifi and bluetooth suddenly aren't available

Hi,


My wifi, sound and Bluetooth suddenly disappeared. Windows says these devices are not installed.


I've tried reinstalling windows.


I can't update the drivers as they don't appear on device manager.


They don't appear on my bios either.


Can anyone help me with this?

:)

 

Can't select paired bluetooth speaker as sound output (Windows 10)

I just got a new bluetooth speaker, an Urbanears Stammen (concrete grey)

I can connect to it from my phone, using Bluetooth, and play back sound no problem. But I can't get my Windows 10 laptop (Dell XPS 15) to use it as a playback device.

I can connect and pair to it no problem, as you see in the screenshot below





It also shows up under bluetooth in the device manager. It's not listed under "Audio inputs and outputs", which I thought it should be, but I can see it under "Sound, video and game controllers".





But I can't select it as a playback device





I found this relevant superuser question: Windows 10 computer paired w/ bluetooth speaker, but doesn't send music to speaker

And I tried the suggested steps listed there, but nothing helped

Any further ideas I could try?
