I have recently upgraded to Windows 10 from Windows 7, and have found 1 very annoying problem, any time a small video plays on a website in any browser my computer completely freezes. I cant move the mouse pres Ctrl, Alt Del. nothign works i have to hard reboot my PC. 1st i had thought it a video driver issue so have updated them but yet it still happens, i have played videos through Plex and have watched a few episodes of a show back to back and no problems it only seems to happen in a browser.

Any help much appreciated
