Webcam not Working

Hello @Womanofword4! Welcome to the community. 

When you attempt to use the webcam, does it actually display an error message saying it can't find the camera or something along those lines? If it's not, it's possible that there's just some kind of flap/screen covering the camera. Some laptops will include a privacy cover you can move out of the way for a webcam, though I'm not sure if Dell does this or not. 

Check the function keys on the top row of your keyboard and see if any of them have a camera icon. If so, press that function key and see if the camera will turn on. If it doesn't, try pressing FN + that function key and see if that works. Normally there's a light next to the webcam that will come on when the camera is active.

If that doesn't do it, right-click your start button and go to Device Manager. Check for a "Camera" category and if you see one, expand it and uninstall the webcam. If you don't see a Camera category, check for "Imaging Devices" and "Human Interface Devices" and see if either of those have a webcam listed, and uninstall it if so. After that restart the computer. 

If there is no webcam listed in Device Manager, we'd want to check Dell's website to see if they have webcam drivers available, but without knowing exactly which Inspiron 7000 model you have I can't provide the link. You could go to Dell's website yourself and it can auto-detect your model: https://www.dell.com/support/home/us/en/04?app=drivers
