I have been using a computer for years but have never opened it.  I'm
intimidated!!!

I know it needs to be cleaned because it's sat on the floor for about three
years and I have a dog that sheds.

I could take it to a computer repair business to clean the inside, but I
thought maybe I should try to clean it myself.

Is opening and cleaning the inside of the computer risky for a first-timer?

How does "one" clean the inside?  What materials do I need?
