One of the worst things for any electronic component is “heat”. Cooling is essential for electronic components! Every six months I clean the inside of my system and perform maintenance on the electrical contacts of each card. REMEMBER Grounding is essential always when performing maintenance.
Semi-Annual Hardware Cleaning
Over a period of about six months your system regardless of its location will build up dust and debris on the fan blades within the system. The heat sink atop of the processor builds up enough dirt and debris to clog the natural air flow around and over the processor.
Fan Cleaning
I remove each fan first, and clean with simple green, taking note of the fan blades as to re-install correctly when finished. (I have inadvertently placed one in reverse, instead of pulling air out of the case, I was feeding ambient air into the case, because I did not pay attention to the fans orientation upon removal.)
Processor & Heat Sink Cleaning
After you clean all case fans, then turn your attention to the processor heat sink/cooling fan, remove it carefully and then separate the two components. Clean both the fan and the heat sink.
NOTE: There should never be any reason to disturb the processor, however for me I can’t resist. I re-seat carefully the processor and lock it into place. Sometimes the (heat dissipating paste) will make you think that the heat sink and the processor are glued together, because the paste becomes hardened over time. Thus the reason to NOT over use the paste. Re-assemble all components and replace. You now have a clean air circulation corridor over the major components.
Peripheral Cleaning
Remove each card (one at a time), using an eraser preferably a (white) eraser, clean all the gold contacts front and back of every card. Using a can of air, blow out each card slot. Replace the cards and seat firmly. Remove card readers, or using air blow out all card ports. You can clean the contacts as mentioned above, but is not recommended unless you are having trouble reading your cards. Open the DVD tray, using air blow out from front to back your DVD, while the case is open. Open the door of the floppy, if it is installed and blow out dust from inside. Remove the power supply and using compressed air blow out any dust, debris from the power supply. DO NOT ATTEMPT to open the Power Supply, this will VOID the warranty, and there are components inside that could kill you, if discharged.
Replace the power supply and plug in component power cables.
Support the case open side DOWN, and using canned air blow out the entire case, removing any dust and debris. Replace case cover, after a final check of all power and data cables, card seats, processor cooling fan etc.. You now have a clean hardware system. I recommend this twice a year for a dependable system.
Now your computer is clean and can “breathe” again.
“Remove each card (one at a time), using an eraser preferably a (white) eraser, clean all the gold contacts front and back of every card.”
I use DeoxIT® Gold (http://store.caig.com/s.nl/sc.2/category.292/.f) for this step, but only once, upon installation. I’ve gotten the kind of reliability I once got from Stabilant 22 (http://www.micro-tools.com/store/SearchByKeyword.aspx?word=stabilant), but at a friendlier price. With the protective, conductive, layer of DeoxIT® Gold in place, cleaning the contacts on peripheral cards has been unnecessary on my last few machines. (Stabilant 22 is just as good–some would say better–but at a stiffer premium in pricing.)
One thing: when cleaning processor fans, first, of course, use some canned air, but DO gently hold the fan blades to prevent unbalanced spinning. Also, IF one removed the heat sink from the processor, cleaning off the old heat-conductive paste and replacing it with new is a Very Good Thing. Here are instructions for application of various Arctic Silver products:

I do appreciate (and re-emphasize) your warning about the power supply. Folks who don’t know EXACTLY what they’re doing ought to keep their hands out of it. Blowing it out should be sufficient to keep it going… until it’s time to replace it. *heh*
One last thing: I’d change the order of cleaning. Support the open case upside down and blow it out first in the order of cleaning. That way, when blowing debris out of card slots, etc., there’s a smaller chance of blowing debris INTO them as well.
Great feedback and advice–thank you!

To obviate the need for cleaning peripheral card edge connectors or slots, I recommend using either Stabilant 22 or DeoxIT Gold on the contacts. Ditto for RAM. These products prevent the need to clean contacts and are designed to provide an even better electrical connection between contact points. Good stuff. These products seriously improve reliability, in my experience.
David, thanks for the tip!
