Why should you have your computer cleaned?
I have worked on many computers that stopped operating due
only to the huge amount of dirt within them. In at least 5
separate occasions, I was presented with a totally dead non-working
computer that started working again after removing piles of dirt from inside of
it. Its very probable that many of the permanently dead systems where I
found huge amounts of dust were ruined because of it. To illustrate my
point, have a look at some pictures here of what can happen to your computer if
you keep it on a bare floor or in a dirty environment.
