Did this machine come with Windows 10 or was it an upgrade from a shipped Windows 8? Arduino Ch340 Driver Windows 10. The reason I ask is that you might have the Windows 8 drivers still for some hardware so go to HP's site (no where else) and download the correct drivers for your machine for Windows 10 and install them. Then make sure you have the latest version of Skype. It is unlikely that both the camera and the mic are bad, it is more likely that the drivers or the program is at fault. You can get tech support from HP via phone and probably remote support as well from HP and they can eliminate a few other possibilities before deciding you need to send it back to them. You have to be a little bit crazy to keep you from going insane.
