The other day i bought a webcam called 'Microsoft LifeCam VX-700' for my laptop as my laptop didnt come with a built in one stupidly, when it should have. But anyway, it doesnt have a disc installation, it's a simple plug into a USB port and it will install itself on that way. It worked for a few days. But i accidentally plugged it into a different USB port once when i had other things connected to my laptop, and now it wont work because my laptop think the webcam is already in use by the other USB port, and on thing like IM, it comes up blank, and will constantly say i have a webcam when it isnt even plugged in. Is there any way to solve this without wiping my laptop ? Like taking the webcam back and swapping it for a new one ?
