usb - Cannot connect my Moto X to Windows 7 PC

I cannot connect my Moto X to Windows 7, 32-bit PC via USB. After doing some research normal solutions people found were

1. Enabling MTP in connection settings.


2. Disabling USB debugging in Dev. settings.


3. Updating drivers.


4. Updating windows media player.

I've tried all of this still my PC can't detect Moto X as USB storage device. It shows the device in - Control Panel\Hardware and Sound\Devices and Printers, but says this device does not work properly as Windows cannot load its drivers. It gives option to re install drivers in troubleshooting but everytime I do it the device driver is not successfully installed.
