HP Pavillion DV6000's web cam not working with Windows XP Professional?

I have this laptop HP Pavillion DV6000, which initially came with Windows Vista Home Premium, however after wards I replaced Vista with XP Professional as Vista was not compatable with most of the drivers.

Now all the hardware is working properly except the Webcam, it just fails, when started from my computer a message that ';Creation of the video preview falied, please check the device connection and make sure that the device is not being used by another application or user'; and with other applications like Yahoo and Windows messenger it gives a message ';No web cam found';

Please help on how to make the webcam work with Windows XP professional, I have tried installing the latest drivers from the Hp sight, but it was no good.HP Pavillion DV6000's web cam not working with Windows XP Professional?
yeah, you need drivers for that webcam as you said that you changed the operating system....you can get it from HP website, select your model and install the webcam drivers which are compatible with windows Xp....otherwise contact them on website and ask for particular drivers...
