Did you disable flash hardware acceleration? They flipped that on recently and when I see flash crash I turn the off.
If you can't find an alternative flash player with google or duckduckgo, I won't either. Try the setting I noted.
Help, my PC with Windows 10 won't shut down properly
Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
