It is stated there my dear..
the error is on lv321av.sys which is a logitech company manufactured webcam.
further information you can refer below link.
http://www.runscanner.net/filelibrary/lv321av.sys.htmli wish to assist you on this but i am afraid i couldn't as you are too new too.
maybe let the seniors who are capable to guide you do it as i worry i might spoil your lappy.
the worse case is you know wat is going on with your lappy and send to shop to ask them help you.
maybe that is better for you rather than you DIY.
