• Answer:

  I have this same thing happen to my computer. The problem is the hardware in my computer is working too hard for the operating system. When the computer gets to 100 degrees Celsius, it automatically shuts off as that's too hot. You can fix this by getting a new processor. You need one that's better than the one you have now. If you're using a laptop, get an Intel processor, not an AMD. After buying one, you can take it to a computer geek and have him or her put the new processor in for you. Another way to fix this would be to downgrade your operating system. If you're using Vista, you'd have to go to XP, if you're using 7, you'd have to go to Vista. If you've upgraded your OS, look online to see how to downgrade. If you're still using the original OS, you'll have to find a place that sells a clean copy of an earlier version Windows. -- And for you're second question: I just thought of something else. There might be too much dirt and dust inside the computer. Take it to a computer geek and have them look at it. If the problem still persists, it probably is the processor.
