I don't think that is the case. Perhaps, something, somewhere might 
think it is getting too hot (an in a software, firmware issue). But I've 
never had it reboot during any times of stressing. I used to use a 
program 'think-fan' to control the fans. With that, it never got above 
80*c. I removed the program (thinking that perhaps something external 
controlling the fans was causing some embedded controller to freak out 
and restart the machine or something). I've since uninstalled it, and 
with stock control, the temps get to 90*c, but as I've said, doing video 
encoding for hours or any other stress testing has never caused an 
issue. It seems to reboot at surreal times, like I'll be typing and stop 
to take a sip of coffee then boom, screen goes black and then I'm 
watching grub load up.

Thanks for the tips though.
