Went on the YouTube home page and the dark night advert, running adobe flash player, crashed my computer and it rebooted. It rebooted asking if I wanted to go into safe mode. I was using the Google chrome web browser and I just checked that I do have the latest adobe flash version and the same problem occurred in internet explorer. I just ran a hardware diagnostics tool and no problems were reported. This has not just been happening with the youtube homepage advert but from time to time with pages with a lot of adobe flash content. Playing videos usinf flash player is fine. Any ideas whats the causing the problem and how to fix it? Thanks in advance.
