I don’t know if many people are aware of this or not but if you have a computer that is at least a year old, it has dust inside of it.  Not just on top of the parts but inside of them as well.

It’s a good idea to buy a can of compressed air, that is unless you have an actual air compressor.  Either way, just unplug everything from the back of it and bring it outside.  Open the side door of it by unscrewing the 2 screws in the back then start blowing things.

You will be surprised when all of a sudden you see a dust cloud forming right in front of you as all of the dust starts shooting out of places you didn’t even know dust could exist.  This may not help your computer perform faster or efficiently but I’m sure it can’t be good for the fans or your CPU’s heat sink to be that dusty.

We don’t have an air compressor anymore so I went to Walgreen’s and bought a can of compressed air for $7.99 (WOW $8 for air!) and came home and opened both computers and just started blowing all the dust out.  I was shocked at how much dust came out of them.  The CPU’s heat sink had a lot of dust and so did the power supply fan and case fan.  I was actually shocked at how much dust was in the case fan compared to the rest of the computer.

The reason I did this is because Chips power supply died, he couldn’t even turn his computer on anymore and when I opened his computer up to take it out I could see all this dust in there.  I figured it was that time again but I was out of canned air so I figured now is as good as any to buy another can.

So that is my tip for the day.  You can buy a little car tire air compressor that plugs into your cars lighter socket for around $20 and it will work just as good as a $8 can of compressed air and it will last you a lot longer than the cans do.  It’s worth it knowing your computer isn’t going to have all that dust inside of it.  I blow the dust out of both computers at least 2 or 3 times a year and you should too.
