I just got a webcam (Logitech C920) and hooked it up to my Dell XPS 8900 desktop and I am getting really jittery video at any resolution greater than 360p.  

I took a quick phone video of what the screen looks like and uploaded to Youtube.  See link:

Not sure what is going on - any help would be appreciated.  I don't know if this is a problem with the video card, or something else. 

The machine is an XPS 8900 desktop.  Windows 7 Pro, 1TB HDD, 16GB RAM, stock GeForce GT730 video card.

I did a dump of the NVDIA system info from the system tray NVDIA app.  Here it is below.  Any suggestions would be great. It's a bummer having a 1080p webcam but having to run it at 360p.

Remove/uninstall webcam (via Device Manager) and all software for the webcam.

 

See if problem continues.
