Dell Vostro 3400 Webcam not working - Drivers required

Hello,

WEBCAM of my Dell Vostro 3400 laptop is not working. 

I think one possible reason for the issue could be if the drivers of the webcam are missing as "Imaging Devices" is not being shown in the "Device Manager".

So, please provide the drivers or the link to download the drivers for Dell Vostro 3400 WEBCAM. Also, suggest if there is another possible reason for the issue and how could that be resolved.

I'm using Windows 8.1 (32 bit) on this system.

Thanks in advance.
