To solve the issue, open Device Manager on your computer to reinstall the driver for your device while your device is connected with your PC via a USB cable.

Microsoft Windows Vista and 7 users

To open Device manager on your computer

Click on the Start button. 
In the Search box, type device manager, and then press enter. 

To reinstall the drivers for your device

Scroll down to the Universal Serial Bus controllers (USB section) of the Device Manager window. 
Look for an MTP Device: Media Device, Unknown Device or any other reference to your phone. Click on this entry and choose "Uninstall" whilst leaving the device connected. 
Wait a few minutes, and the computer will reinstall the drivers for the device.
Now, the phone is accessible via Computer/My Computer on your computer.

finally solved, well i just paired my phone with laptop (bluetooth) because of which the phone was not operating in mtp mode 

1. i just deleted bluetooth pairing from laptop

2. deleted bluetooth pairing from phone

3. disabled c201 (some number) drivers as i could see 2 drivers of that name in usb drivers section of device manager , i disabled both,which promptedd me to restart 

4. i just accepted to restart

5. after restart again i open the device manager and in usb drivers sectio i could see the disabled drivers status as disabled, hence i enabled it. hollllllllllllllllllllla thats all.
