In order to fix the problems, I recommend that you update your webcam drivers. Access the official web page, select your operating system, and download the latest webcam files. After that, press Windows + Pause/Break key combination and open Device Manager. Expand the Imaging devices list, right-click on the webcam driver, and select Update Driver Software. Use the Browse option to navigate to the downloaded package, select the driver, and install it following the on-screen instructions. If the issue persists, try using another webcam capture utility from Software Informer database.
