My laptop will often over heat when rendering videos or doing other intense tasks if I dont plug in my cooling stand; now my complaint is, when this happens, the computer automatically shuts down instantly with no warning what so ever. This really annoys me as there is a heat sensor in computers otherwise it wouldn't know to turn off in the first place, and also programs like HWMonitor use it. So what I want to know is, why doesn't windows give you a message warning you that your PC is overheating, so you can do something about it before it's too late.
