The PC maintenance should be done not only inside but also outside. It's a habit we should adopt both for hygiene and for aesthetics. Sometimes a lack of cleanliness, dirt dust and chemicals can cause a malfunction of the PC (shorts, warm-ups, crashes, noise components).
In what follows I will try not to use difficult to obtain materials or products that are not within our reach.
The cable that goes behind the CPU and power supplies must be unplugged, turned off all devices and peripherals are disconnected from the CPU, for comfort and safety is not enough off from the switch located at the source.
ATTENTION!
When we begin to clean the cpu, it would be OK to have placed a wrist strap, is mandatory to have a shoe with good insulation, if possible, place ourselves in a dry environment and do discharge static electricity from your body (touching the metal parts of the Compaq HP nc6120 battery or some other metal objects).
If you read the advice, you can unscrew the side of the cpu and open it (careful with the edges of the box!, You can cut). When cleaning do not clean all components, but that they need cleaning.
In principle we will clean the fans on the back of the cpu, and if there are, front, these are the point that facilitates the entry of dust into the HP dv2000 battery. Being in constant motion, cause dust particles to enter through it and some from sticking to the blades.
For cleaning it will have several options you can use a vacuum cleaner, a spray of compressed air or a brush. If you use a vacuum cleaner, be careful not to suck any jumper. If you see dirt and will not want to clean more effectively, if you dare, you can remove the fan (look closely at what position) and clean carefully.
Once cleaned the fans back and front, focus attention on the heatsink / CPU fan, surely the sink, which has several sheets, will fluff them off with compressed air spray or brush. If you happen to remove the heatsink, before replacing the thermal paste should be cleaned with a dry cloth and leave no rest, remember to leave as was the thermal paste, not close, but a slight layer to prevent air from the processor and heatsink. Thus we end up with the cleaning of fans and start with the motherboard.
To clean your motherboard does not use liquid at any time, we deal mainly with the brush and much patience.
When cleaning slots (slots) of memory cards and a spray of compressed air (not a lubricant and driver, would cause short circuits), in contrast to clean the edges of memories and cards, rub with an eraser until improvement is noticed that the color gold. If we do a more thorough cleaning, we can disconnect the connectors that are in the bale and remove the jumpers base, taking care of the position in which they were, because a bad connection can cause problems, if necessary, and do not have much memory takes several photos, to remember their positions.
