Webcam not working on Laptop

[derbyjozef]

I have not used it in quite a while. Now when I try and use it, the webcam does not show up in Device Manager. If I bring up Windows Live Messenger > Tools > Audio Video setup, it states that no webcam is installed.

I have tried reinstalling the latest webcam driver, resetting bios to the default values, using System Restore to restore the original driver, and I have reinstalled the latest bios. None of these actions had any affect.

Is there anything that would cause it to be disabled? Why doesn't my laptop find the webcam/webcam driver?

Are there any yellow exclamation marks in the Device Manager?

In addition to looking in Device Manager, is this a laptop? Is this a built-in cam? If so, also chekck BIOS to see if it appears there and can be enabled/disabled/.
