I have an HP notebook running Windows 7 Home with an integrated webcam. I have had the computer for 18+ months and never had problems with the webcam till now. Yesterday it still worked fine. Now the computer is not recognizing the device. Restart, reinstallation of the driver and driver update have all been to no avail. The computer gives me error messages saying there is no webcam device and where hardware devices are shown in control panel, it shows the device with an exclamation mark. I would appreciate any help someone could provide in reactivating this webcam.
