When the fan is spinning like crazy, is it actually throwing out hot air? Put your hand about 5 inches away from the the vent - you should feel the hot air on your hand. I tried downloading CPU tweak and CrystalCPUID but I have no idea what these terms mean, or what I can do. I thought I am willing to underclock the CPU a bit if that would help (someone else mentioned somewhere that it does help, but I have no clue on how to underclock. The way I see it, there is either a ton of dust below the motherboard (I have never actually lifted the motherboard from the casing yet as that is below), or this laptop has serious problems.

This is obviously overheating, but I've taken my laptop apart a million times (i replaced the DVD drive with a hard drive a long time ago and ive made sure to clean all the dust I can see with a air can, and this has not helped. When not busy, the temps are usually from 60-80C In CPUID HWMonitor it shows that the CPU temps are running up to over 100C at that time. In all of these cases the fan starts spinning like crazy, and it just turns off. It also happens when I try changing the notscripts setting in google chrome for a website, where it reloads the pages.

This especially happens when I try to either use the wifi, or the bluetooth (to tether to my phone). It has an Intel i5 520m problem is that my laptop overheats and shuts down by itself constantly.
