VIDEOS PLAYING SOUND ONLY AND A BLACK SCREEN IN CHROME...For those using Chrome and not finding all these settings under options, accounts, security, etc., that everyone is suggesting, I was having the same problem. I found a solution. I went to play the video by clicking it, when it opened, I had the black screen and sound. RIGHT CLICK>SETTINGS> UN-CHECK "ENABLE HARDWARE ACCELERATION" I kept trying to click the box to un-check it, but nothing was happening and I couldn't click the other tabs on the menu or close it. I finally found that I could click just to the left of the box, on the edge of it almost, and it UNCHECKED THE BOX. Then it let me close the box and I restarted the video, IT WORKED!

Tried it and it doesn't help! Still the same issue happening on FireFox!
