Windows 10: Computer freezes - USB Icon pops up when nothing is plugged in?

My laptop frequently freezes for brief periods, about 5 seconds. Every time it occurs, the icon on the bottom task bar indicating that a USB flash drive is detected will pop up, when nothing is plugged in. It goes away when the computer unfreezes. Does anyone know what could be causing this?

:)

 

USB Drives plugged in but No Safely Remove Icon in Tray, and


....no drives listed in Hardware List.

When I plug USB drives in, the Safely Remove Hardware icon does not appear in in system tray (its not hidden either)

First, I went to Settings > Personalization > Taskbar > Select which Icons Appear on the Taskbar...





.. and found it was already on

Next I tried using the solution in this post...

Solved No safely remove icon in tray any more after Windows 10 Anniversary up - Windows 10 Forums

...making a shortcut from "rundll32 shell32.dll,Control_RunDLL hotplug.dll", but when I run the shortcut, there are no devices listed...





(in this screenshot, you can see two USB drives in the Explorer window in the BG but nothing listed in the panel. )

NOTE: They are listed in Disk Management and in the Device Manager under Disk Drives, and they function just fine..
I think the Safely Remove Hardware icon is not appearing because despite being detected and showing in Explorer, Device Manager and Disk Management, its not being listed in this panel for some reason.


NOTE2: I recently installed a new motherboard.

ASUS B150M-A
CPU Intel Core i5 - 6500 (3.2 GHz)
Mem 4096 MB (DDR4 - 2133)

I am 100% sure it was working before that, but I cannot say for sure if it was still working after that.
A friend suggested that it might be a setting in BIOS, but I have looked through it and nothing stands out.

Any suggestions would be welcome.


ETA: this is not the system listed in my System Specs page. That is another computer which I still have.

 

USB problem

I have difficulty booting up computer at usb ports detecting and I think of my webcam cause it.
The computer boot screen is having a big delay it freeze for 30 or 60 seconds at the usb scanning step. Sometimes in Windows it says Unknown hardware at windows opening. Could it be my usb ports that begin to sucks or my webcam is having trouble ? (No other usb devices plugged other than wireless usb key for keyboard-mouse combo)

 

help. USB drive isn't assigned a drive letter.

Any usb flash drive I plug into my computer isn't assigned a drive letter. The physical drive shows in the "safely remove hardware" but it doesnt show up in disk management. I have tried to populate the volume thru the safely remove hardware properties window and it does pop up in the list but it doesn't stay there. This isn't a format or assign a letter problem. It's more complicated then that. Maybe one of the services needed for usb drive management was disabled? Suggestions needed. btw external usb harddrives work fine.
