I have been experiencing immediate system shutdowns while watching certain youtube videos. The computer shuts down with no hesitation or warning - as if I'd held the power button. This only happens while viewing certain videos. Every time I've experienced the problem, I've been in the middle of a controversial progressivist or revolutionary type clip. I have noticed the phenomenon is particular to certain videos. Not every video crashes my computer - most play fine. I noticed the problem initially running Mint 13 with mate, but have since re-installed to 14 mate and experienced the same problem. I have so-far experienced the issue on two different wifi connections. I have noticed that if a shutdown occurs, after immediately rebooting and reloading the last viewed page, I get another shutdown within seconds, whereas the first would have been after the video played for a few minutes. The nature of the problem leads me to believe it is a targeted shutdown, due to government surveillance paranoia. I really have no proof though. Are there any logfiles or other places to look that would help me find the root of the problem? Is there any way to reject/override a shutdown command? lastly is there any simple approach to downloading flash videos first and then watching them with vlc (or another open player) embedded in the webpage? Ideally I'd like to bypass flash altogether.
Here is one of the videos I was watching when the shutdown occured:
Firefox version 18.0.1
Adobe Flash version: 18.104.22.168
Gnash version 0.8.11 (I have even experienced the problem when using gnash with adobe flash disabled)
Linux Mint 14 32-bit with Mate

Again, I can watch hours worth of youtube videos and videos from other sites, its only when I watch anything that would clearly put up a red flag on any government surveillance software that bombs my system... which is why I feel I'm being attacked, but again, no proof. any advice on where to look is much appreciated. Thanks.
