Try a common settings change and if it still crashes, talk to your PC's maker about repairs.
"Unfortunately, at this point your best solution is to leave hardware acceleration disabled"
And no, many folk are not running new PCs from May 2014 so I continue to disable this.
When playing a video clip online, The video will stop and I will get a white panel with a exclamation mark in a circle.
Sometimes I can right click that and refresh and can get the video to play, but mostly I can do nothing with it.
It happens with both IE10 and the latest Firefox.
I am using the Comcast version of Norton suite anti virus if that makes any difference.
Any advise would be appreciated
