How to turn on Sony Vaio built in Webcam on Windows 7

Marigrc2...I verified my driver...it is the most updated version.  Device manager shows Sony Visual Communication Camera is workly properly!  ha ha.. ok.. But it doesn't work!!!  HELP! 

I can turn on the webcam companion 3.  I click on capture.  The green light turns on.  The picture box is there but no picture...just black.  Could this be a computer problem..i.e  the camera needs to be replaced or is it a software issue? Also there's a message that states components of ArcSoft Magic i-Visual Effect are being used by another application.  I do have Skype and I used to Skype with video with no problem until recently.   I have until November before my extended warranty plan expires so I could send it in to have the camera replaced BUT I need my computer for work and it will take 2-4 weeks.  Marigrc or ANYONE..PLEASE ADVISE.  Thanks in Advance :)

I do not have Arcsoft Webcam companion on my Sony Viao.
