Firstly, I apologize for my English.
Second thing, I have HP Envy dv6 7210tx 3rd Gen. i7 having Windows 8.1, For the last few days, my laptop wasn't working properly. so i "Refresh" it by using a Win 8.1 DVD. After refeshing, My Integrated HP Truevision HD webcam was working properly but one day suddenly it stopped working. My Cyberlink youcam responded to Turn On the intergrated webcam. i dont know how to Turn it ON. I check the Device Manager, My device Manger doesn't has the "Imaging Device". but it had Hp webcam in Human Interface Manager. Unfortunately, I uninstalled it. I refreshed it again. Installed All the drivers again. People say webcam driver is included in Youcam Software. i did everything i could. but i neither have the imaging device nor the Hp webcam. Please Help.
the other thing, is there any Hp recovery manager for Hp envy dv6? because i didn't it even in the HP drivers for Envy dv6.
