At least once a year, you should remove the CPU housing and blow out the insides of your computer system. Computer equipment is temperature sensitive. Although it might not be thought of in terms of traditional maintenance, you should make sure that the room temperature in which you house your computer equipment is kept at a uniform level. Anywhere from about 65 degrees to 85 degrees Fahrenheit is acceptable. If temperature seems to become a problem with a computer system, the first line of defense is to periodically open your system and to pull and re-seat expansion cards and ribbon cables.
Temperature variations can also occur where integrated circuits are socketed on a motherboard.
Most average users should NOT attempt to pull and re-seat integrated circuits. This is odd. The final piece of computer care and maintenance advice should be practiced every time you use your computer. One user, that we've had experience dealing with, adopted this as a standard operating procedure.
