Computer randomly shuts itself down.

My laptop will literally get hot after 20 minutes. The fan starts running loud and gets so hot I have a perma burn mark on my leg.

I even have it hanging off my desk a bit to get more air into the fan. It started doing this the day I bought it. When I run maple, its even worse. The fan never stops running and it shuts itself off. I'm pretty pissed I bought a lappy that I can't use the way I want because it gets so damn hot.

BTW~ How would I go about cleaning my laptop? ( I have never owned one before)

I hope you haven't been running your laptop on a carpet or on your bed, as not only does it not get enough air this way, but it also acts as a vacuum cleaner and sucks in a lot more dust than it normally would. To clean your laptop, you will most likely need to take some screws out and take off the fan cover and/or other parts, depending on how your laptop was built. You could try blowing out dust with a compressed air can, but how you should aim it, again, depends on your laptop -- the designs are not standard.

Laptops shouldn't get that hot. You might want to send it in for repairs while you still have your warranty. >_>
