Crazy question, but what would youtube and my PC restartig have in common?

[MouthBoy]

OK, as title really. In the last 3-4days, I have had 3 crashes on my machine where the screen has turned black and after a few seconds rebooted itself. The only common factor is youtube, usually full screen youtube. It sounds stupid I know but thats the only time it crashes. I guess it might be something to do with video drivers, but surely I would have noticed something else going wrong if it was that?

So any ideas? Or anything I can do to test more?

Problem with GPU drivers or Adobe Flash player perhaps? I would start by reinstalling both with the latest version from the vendors website and/or try another web browser too.

Another vote for flash.

Yea I just updated my Nvidia drivers and about to grab flash too. Thanks for the advice and hopefully it will solve the issue.
