Overheating Problem dv6, help getting the dust out.

[Joshc]

For a while now my Dv6 laptop has had a problem with over heating. It's around over 6 months old. Its continually getting hotter.

Now I figure it's the dust, as it is in a high dust environment, my desk I have it on constantly has a layer of dust on it no matter how many times I clean it. I do not currently have a cooling pad. (dv6 notebook)

What I want to do is clean out the dust from inside. Now I'm not an expert and I've never done it before, It looks kind of complicated to get the screws out etc. I found a guide on the net which seems good at taking it off but I'm not sure (http://forum.notebookreview.com/showthread.php?t=226910). 

What I would like to know is:

1) Is there an official step by step guide or an equivelent guide I can follow.

2) Is there anything I need to know, not to do, to do, before/during taking the case off and cleaning ( what not to touch what not to unscrew etc)

3) How many cans of compressed air would I need to fully clean it.

4) Anything else I would need to know before attemping to clean it

Also I had a problem with a sort of rattling/loud humming, sound comming from the left side, can't determine wether its the harddrive or fan. It is an intermittent sound, it normally starts up when I turn on the laptop, but ends up stopping sometime later.

Any and all help is very welcome.
