Question: whenever i try watching a vedio a green screen comes up but i can hear the audio? 

Answer: It sounds like you need to install the correct video codec for the video you are trying to watch.  You can determine which codec you need by using a program like the GSpot Codec Information Appliance : http://www.headbands.com/gspot/\n\nFurthermore, I would recommend installing a codec pack from the following website : http://mirror2.edskes.com/
