The problem is that when you insert any usb device: memory card, HDD, usb-stick, mouse or keyboard ,- the PC freezes. Nothing can be done to unfreeze it, except manually rebooting PC by pressing reset button on the case. The problem is very common and spread among Windows users, and it can be fixed in few approaches.

I. Enable/(Start) Universal Plug & Play Device Host service in Windows services.

II. The second approach is to remove and reinstall all USB controllers.

1.Go to Start > Run > type in: 'sysdm.cpl' without quotation marks and press Enter.

2. Navigate to Hardware tab and click on Device Manager button.

3. Expand Universal Serial Bus controllers.

4. Right click every device under Universal Serial Bus controllers node, and then click Uninstall to remove one at a time.

5. Restart the PC and then reinstall the USB controllers.

6. Plug in USB storage device into USB-port, make sure the issue is resolved.

III. The third approach relies on a registry fix (this fix will also work if the usb-device doesn't show up in My Computer):

1. Go to Start > Run > type in: 'regedit' without quotation marks. Press Enter.

2. In the opened window navigate to the following registry key:

HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices

2. On the right pane, find and locate the problem device letter, which corresponds to problem device, delete this registry entry:

Note: The registry key should have the name that resembles the format of \DosDevice\X: where X can be any alphabet letter which corresponding to your physical system drive letter.
