I've seen people take them to shops, reload the OS and fight it tough and nail.
My buddy took 3 months to give up the fight. At least I loaned him some USB webcam while he fought it.
I have a HP Pavilion dv9000z CTO Notebook PC with 32 bit Vista (SP2). When I first purchased the laptop, the webcam worked fine. 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?
