Hi steffo,
1. Have you made any recent changes on the computer?
2. Are you unable to use the camera on any other computer?
3. Do you have any security software installed on the computer?
4. What is the version of Windows installed on the computer?
Method 1
I would suggest that you uninstall all the software and drivers related to the camera from the computer and later visit the Microsoft hardware website to install the latest version of software for the camera and check if it works.
Download Webcam & Headset Software

Halima,
Before you offer any more advice I suggest that you try the following experiment.
- Take a working LifeCam.
- Do the Firmware upgrade on it.
- Observe what happens . . which will be as follows: Your LifeCam is now a brick, and will not be recognizable to any computer anywhere.
This kind of extensive "advice" (e.g. Wiggle your ears twice. Poke the camera with a copper rod. Pledge allegiance to the American flag in front of the Post Office), simply illustrates that you have never done steps one through three above.
And this is why many people dislike Microsoft was much as they do. Some people LOATHE Microsoft. I am not one of them. I simply dislike your business practices. They stink.
