PC Camera not working

Hi,

I have Dell inspiron15 which has inbuilt PC camera. It has stopped working. While diagnosing it on Dell portal, it fails to run the tests stating that eiter the device driver is not installed or incorrectly installed. But while checking it from device manager, it stats that you have latest updated driver in your machine. Could you please advise what might be the failure reason.

Regards,

Sanchit
