Windows 10: Unknown Device "On: Volume Manager" Drives Inaccessable in Explorer

2 drives SSD and HDD and all usb flash drives I plug in are showing up in device manager with this error. It all happened at the same time so I'm hesitant to call a case of mass hardware failure.

I've checked in Properties to upgrade drivers only to be informed that the "best drivers for this device is already installed" against all the drives including HDD's, SSD's and USB drives. the machine runs fine and in Disk Management they are all listed as they should be. Has anyone experienced a similar problem? All hard drives appear in the BIOS as they should.

 

Network devices listed under Unknown in Device Manager


I have a Dell Inspiron M731R laptop upgraded from Windows 8.1 to Windows 10 Home 64-Bit that suddenly quit connecting to the home network. Was using wireless, so switched to an Ethernet cable, but still no luck. I just discovered that ALL of the network-related devices are now listed under an "Unknown" tab in the Device Manager. A check of properties of each item in that folder says they are all working properly, but that obviously isn't the case. I tried uninstalling each of the 4 items, but when they are recognized again they still show up under the Unknown tab. Any suggestions would be welcome.
