My ACER laptop gets very hot but only when I haven't cleaned it for a while as the fan gets clogged up with dust. It only tends to happen in games but it will randomly turn off sometimes at any time. my computer is an Acer 7540/7540G/7240 series laptop running windows 7 home premium that I have had for about 3 years and have had a lot of problems with which I have managed to fix up until now.
