I have a laptop that will not play news video clips, play on-line greeting cards, allow me to watch programs on PBS, add items to on-line shopping carts, allow me to post here or play You Tube videos. I can not find a setting to allow them to be played. I run Win 7 64 bit and Google Chrome. I also have 2 desktops running Win 7 64 bit and Google Chrome that work fine. My guess is some setting on my laptop needs to be changed. Any suggestions?
