Recently my PC will randomly shut down when I am playing a game and I will hear a eeehhh sound in my headset. Also, last time this happened my computer wouldnt turn on for a few minutes. And a few minutes ago my computer restarted by itself. When this happens the power cord connecting to the power supply is hot to the touch, I was wondering what the problem would be. The outlet in my wall? The power supply? Or the power cable? Thank you!

I think I found the problem. I unresticted the amount of bandwidth I would use a few days ago. I changed it back and am not having problems. Could that have been the problem?
