After performing a clean install, did you perform a windows update?
I remember seeing a camera update when I was updating my laptop; it was under "Optional Updates."
If that still doesn't work, pop in a Linux Distro e.g. Zorin, let it boot as a trial then see if the camera works. This is to find out if your camera is a hardware or software issue. You could also try installing Windows 7 again.
