Notebook Wireless and Networking

hi i don't know much about computers but I've recently had a up date on my windows 10  and i think it damaged my Bluetooth driver or something like that also In device manager, Bluetooth Device only shows up after I set device manager to show hidden devices  and once I do that the only thing under the Bluetooth Device is "Ralink Bluetooth PCIe Adapter that has a yellow exclamation point sign in the logo. 

when i click update driver then click search for automatic drivers it says that windows has determined that the best driver is already installed , they may be better drivers on windows update or the driver manufacture website. 

I don't understand what that really means but at the lower part of the page it says search for updated drivers on windows update and nothing happens 

but now when i try again but click properties this time this is what pops up:

Windows cannot load the device driver for this hardware. The driver may be corrupted or missing. (Code 39)

Windows cannot verify the digital signature for this file. The signing certificate for this file has been revoked.

so i thought that maybe i just need to get a download windows 10 but my device cant run that, or because it was after that update i got from when  i shut down my pc before this whole problem happened.  on my pc (irl pc box) a link: www.hp.com/support  it does not help me in anyway at all.

i also have a problem with my Logitech Z313speaker system too,  I've trouble shoot it many times it says:

the audio peripheral doesn't appear to be plugged in check the connection. if I'm being honest I'm not sure on what that means and if i trouble shoot it again it says something appears to be unplugged. (also i tried to trouble shoot Bluetooth aswell and it says : Bluetooth is not able on this device please try using a external adapter to add Bluetooth capability to this computer)( im dont really know how to do that aswell)

please please please if there is anyone out there to help me just feel free to let me know
