How to install that web cam model PK 635 M in windows 7.. coz evrytime i open my cam in yahoo messenger it say that no camera was found in the system

I noticed that there is no Windows 7 specific driver for this older camera. This can be problematic as the older XP drivers sometimes work and sometimes do not work in Windows 7 32 bit or 64 bit.

Good luck on this compatibility issue with Yahoo Messenger. Maybe try Skype or Windows Live Messenger for video chat.

I dont know how to adjust the color setting of my web cam..its already color green..i already adjust the color but still it didnt work...i tried the advance setting but it didnt work too.

Webcams do not have a perfect system just as the regular cameras as the resolution is also low. So you can make some adjustments with the corrrect lighting as luminance is important, being low can make it look green.
