My in-built camera recently stopped working giving the error message: "error "0xA00F4244 NoCamerasAreAttached""

I've followed the list of steps on the Dell Support page, however nothing seems to be fixing the problem and, indeed, when I follow one step and go into Device Manager, the camera isn't listed.

I've also gone into the Dell Drivers and Downloads page, however there is no camera driver listed.

What can I do? Where can I find the driver for my camera?

Thank you
