Windows 10: Devices Manager lists devices as driverless.

Some of my devices, including my graphics card and ethernet controller, have suddenly been listed under unknown devices rather than their usual category The Video Controller and Audio Devices are what I think is supposed to be an Nvidia GTX 1060 6gb. The Ethernet controller is supposed to be Realtek Gaming Family GbE controller if I remember correctly. The task manager does not list my graphics card either, as it previously did. I believe the card is installed correctly to my motherboard as the display is connected to its HDMI port and its fans are spinning.Once, when I plugged in my mouse,

No hardware listed in Device manager?

I don't konw whathappend but in Device manager and in my Network connections there is nothing where there used to be a Modem listed and all my hardware in Device Manager. What happend and how do I fix this?

 

GPU-Z device list enumeration, device order?

Specifically, how are the the GPUs listed in the drop down sorted, or determined? Vendor and PCI ID? OS hardware device list? Other?

Sorry if this was answered somewhere already. Searching for "GPU LIST ORDER" and like terms were not helpful.

Thanks.

 

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.
