Windows 10: Device Manager failure

When I try to start Device Manager either from Control Panel or otherwise, it shows the blank Device Manager window for a second and then disappears. I have run scanhealth and restorehealth from the DOS window which did nothing, but reported corruption it scanhealth that could not be fixed. Until now no problems. Only MS Win 10 antivirus. Full scan did not resolve the problem. Win 10 troubleshooting does not resolve the problem. How to fix?

Device Manager Un-Hiding Hidden Devices

When you connect a plug and play device, Windows Plug and Play manager detects it, finds and installs the driver. Device Manager lists the device with a solid icon.

The driver is only removed when you uninstall the device, not simply by disconnecting the device. When the device is disconnected, its driver is still installed. By default, Device Manager only displays connected devices. When you show hidden devices, note the Bluetooth icon you see is semi-transparent (not opaque). That indicates a "non-present" device. Sometimes also called a "ghost" device. The driver is still installed but the device is not currently detected (i.e. not connected).

Device can be disconnected when

• Device unplugged (e.g. removing a USB device)
• Turning a device OFF
• Disabling the device in BIOS (then windows won't detect it) or
• Device failure

So

• Check BIOS as suggested
• Check board connections
• Can b/t be turned off by a switch? or keyboard combination?

Also possible the b/t h/w failed
