1. Open ‘Device Manager’ by clicking the Start button. In the search box, type ‘Device Manager’, and then, in the list of results, click ‘Device Manager’.
2. When the device manager pops up, in the list please check for ‘Imaging devices’.
3. Under ‘Imaging devices’ check if you are finding webcam.
4. Right click on the webcam available and click on ‘Uninstall’.
5. Check the box which says delete the software and click ‘OK’.
6. Restart the system and check for issue resolution.

Also, I would suggest that you download the ‘Dell Webcam Central’ and install it.

Please follow the steps below to run the diagnostics for the Webcam on the system.

1.       Open the link http://dell.to/11MXNII 

2.       Select ‘Hardware’ under ‘Choose a Diagnostic Type’.

3.       Select ‘Camera’ under ‘Diagnostic Selector’.

4.       Click on ‘Run Diagnostics’ button.
5.       Let me know the results.
