Hi guys! The problem is: when I play games or doing something hard with my cpu and gpu laptop just turn off without any reason.Its not overheating - the temps are around 40 degree by cels... i noticed my fan cooler make strange noise when is spinning like cycles and can't change its rpm's which is weird... and when I play games by example temps go high so normal rpm's too but they don't, and then kaboom ... shutdown! what'is the problem laptop fan or motherboard? what ya think? when I turn on computer again loading and after a while same thing again. In Bios is ok for minute or two and shut off! Is it possible Bios have sensors to be sensitive if fan is moving normal, and if not to turn off??? or broken motherboard what you think?
