Webcam on HP Pavilion Desktop, 64-bit driver, Windows 7 works intermittently

My webcam has started gradually and over many months.  I was with Vista.  Took me to upgrade to Windows 7, 64-bit, in the hope that it would solve the problem.  I have run programs troubleshooting and followed the suggestions that initially appear to work and then there is a noise of "Ding-Dong" carried by the computer (sometimes several times) and turns off the webcam.  Now with Windows 7, I get a #43 error signal saying that the device is disabled.  It works well or doesn't work at all.  Sometimes, it works when I turn on the computer, sometimes not.

I get the error message as soon as the webcam is stopped.  (The computer beeped a two part when he does this, if I have open registration page, I can see the webcam icon to a green check mark disappear.)  Sometimes it bounces and off several times before you stay off.  The webcam is often (but not always work when I first boot my computer.)

My computer: HP Pavilion Elite 9517c, now on windows 7, 64 bit but the webcam no longer works when I was using Vista - I was hoping that the upgrade would solve the problem

Webcam: model CNF8215, HP webcam, now in port #0003 Hub_0005 (I tried to change USB locations and even the cable, but none of this makes a difference) provider: Microsoft, the hardware ID: USB\VID_03FO & PID_B116 & REV_6457 & MI_02

I tried the sites above, but the webcam appears not on the lists of programs - this is the frustrating part - when the webcam is not working there is nothing to show problems and then when it stops working it is referred to as a "unknown device does not" and I can not find it or any what prgram/device related to it.  It still appears in the list of devices with a yellow!  I did all the troubleshooting suggestions and also updated the drivers of HP. I have not tried to uninstall the webcam when it works (it's what you're suggesting?)   Could you be a little more specific on how I would reinstall it if that's what you're suggesting.  Thank you very much!
