Web Cam Not working in my Laptop

Hello All,

Currently i have Lenovo Y50-70 laptop, i bough new web cam from one of local website called vlogging guru, they mention in their article about top youtuber pewdiepie use same web cam so i buy it. here you can see the exactly web cam what i’m talking about “Logitech Pro 9000” but the problem is when i connect my web cam to my lenovo laptop they show me something error. i’m trying connect my web cam which i bough new but they show me video of laptop web cam which i don’t want to use anymore in Zoom webinar. Actually I’m a teacher from one of local college in USA, due to coronavirus we need to do online classes now a day.
