I was having an issue with watching videos on You Tube on a Chrome browser. Then I read that You Tube will no longer work with Flash player. I deleted Flash player and now it works great. Maybe try deleting Flash and see what happens.
After installing these 3 most recent Windows updates ( Cumulative Update for Windows 10 for x64-based Systems (KB308144
, Update for Windows 10 for x64-based Systems (KB3081452), and Update for Windows 10 for x64-based Systems (KB3081449) ) on 08/27/2015, flash videos will no longer play correctly, i.e. "solid green screen with sound only". Is anyone else having this issue? I was having the same issue on Google Chrome and the issue was solved by turning off "Hardware Acceleration" in Flash Settings. No where to turn off "Hardware Acceleration" in Windows EDGE. I was NOT having this issue till I installed the 3 updates mentioned above.
