I cannot tell you how often I get a PC in that is so dusty inside and the air-flow vents restricted that I don’t know why it hasn’t burned out already!
I know many of you may never think about cleaning your computer, but you really should. I don’t mean cleaning as in cleaning out all the junk that gets on your computer. Let a professional do that. I am talking about physically cleaning the dirt and dust out of it, even an amatuer can do this.
Something as simple as buying a can of compressed air at your local Radio Shack and blowing the dust out of the vents can make a big difference. (If you visit either of the Radio Shacks in Owensboro ask for Josh Thompson at the mall RS or for Jacob at the RS in Wesleyan Park Plaza.)
However, for the really brave, I’ve included a link to a Microsoft site that has an article about how to do a thorough cleaning. https://www.microsoft.com/athome/moredone/cleancomputer.mspx
