Hi, I have a Laptop and I turn it on and will play WC3 for about an hour. After that the screen will turn black and I will not be able to do anything. The sound starts to just repeat over and over like a scratched cd. I will have to manualy shut the computer off by holding in the power button. I have been playing this game for years and it just started doing this. Is my laptop overheating and turning off to keep from damaging it's self? Thanks in advance for your help.
