Hello, I have noticed that sometimes when I am watching live video being streamed from websites on the web that my PC will just shut down. I know that this can be sometimes caused by overheating, or too many programs running at once but usually when I'm watching streaming video that is all I'm doing. It may be caused by fullscreen viewing on the websites, but when I play DVD's or watch movies that I'm downloaded in Full screen this doesn't happen. I don't receive an error message(I know this may be because of a setting that calls for auto restart when errors occur.) the PC will just shut down and then I can hear my HD revving really fast. My PC to my knowledge has a good power source and it is an intel processor 6x T1100 Phantom II so, it should be able to handle quite a bit I would think. Any help would be appreciated, I know you guys are the best because you've helped me before.
