I changed the OS to Windows 7. After changing OS, my webcam stopped working. Where can I find the required drivers for it? I have HP Pavilion DV4-1241 Entertainment Notebook.
Usually after upgrading or installing a fresh copy of Windows, you lose the drivers required for certain hardware to work and have to re-install them. You can try to download HP MediaSmart Webcam, in most instances it installs the driver of your webcam automatically and you can start to use it again, right away.
