If you read this article you will learn the true importance of preventive maintenance as an element of great value to avoid failures in your desktop or laptop PC, avoiding many of the causes of these injuries that affect your computers.

Much of the problems that arise in computer systems can be avoided or prevented if we carry out periodic preventive maintenance of each of the components of the PC.

There are two great enemies of your PC that are heat and moisture. Excess heat accelerates the deterioration of the delicate circuits in your computer. The most common causes of overheating are dust and dirt: ventilation ducts and dense fans can block the flow of air inside the cover, and an even thinner layer of powder can raise the temperature of the components your machine. So you need to keep your system clean inside and out.

The main objective of preventive maintenance is to lengthen the life of the computer and avoid possible failures in the future and basically consists of the physical cleaning Internal and External computer equipment.

Basically, you need to clean the external components and internal components found inside the CPU cabinet.

Among external components may include the cabinet, monitor, keyboard and mouse, and within the internal components that should be cleaned, the motherboard, adapter cards, cables and connectors, power supply are, RAM, fans, drives DVDs, CDs.

The frequency with which you should implement this type of maintenance depends on the computer environment basically, but must also bear in mind the quality of the components thereof. If the PC is in an extremely dirty environment should be cleaned on average every three months, but in clean office environments cleaning should be performed on average once or twice a year.

Although there are on the market a variety of elements that facilitate the task of cleaning tools you should use:

1. A blower or vacuum.
2. Foam to clean the case
3. Contact cleaner spray.
4. A small soft brush.
5. Several hygienic cotton swabs.
6. Pieces of flannel.
7. An antistatic wrist strap
8. thermal grease

Special considerations for cleaning the PC:

• Do not touch the edge connectors cards and memory modules with fingers as moisture forms deposits that eventually corrode the contacts.
• Certain elements merit a complete solution to remove dust from inside such as the power source and heatsink-fan on CPU.
• All environments with PCs should be as clean as possible of dust and other contaminants

In this article, we talk about a pixel of an LCD screen that does not work properly. Here we show you two methods that you can use and make a believer of even the most skeptical. Try it, you lose nothing and then you comment us.

In the first instance, let’s say that a pixel of an LCD screen of any device (monitor, TV, Laptop, PSP, etc.) can be red, blue or green and has three ways to fail:

• Dead Pixel (Dead Pixel): Is one pixel that is always in black, does not emit light of any color or intensity.
• Pixel stuck or locked (stuck-pixel): It is one that only shows two light levels, on or off without going through all the intermediate levels.
• Hot pixel (hot-pixel): Is one pixel is emitting light continuously. This light is red, green or blue and makes its maximum capacity.

These failures can occur at any time on LCD screens with TFT technology, moreover, you can be on your screen from the first-second use. These defects are not covered by the warranty if not exceeding a certain number of pixels. It seems a joke but it is not, at least until companies reduce these defects to the point that changing equipment not mean them an economic imbalance.

To try to solve these failures there are two methods, one for software and a manual.

Software method to repair a damaged pixel

It consists of a small program that produces intense flashes in a small window, which will move to the area where the damaged pixel is found. This can be repeated several times to get the result.

There are many versions of programs that do this work because programming is really very simple. One of the programs you can download the UDPix,  which also helps you detect damaged by putting the entire screen of the same color pixels.

Another useful to repair a damaged pixel software is JScreenFix , which has different applications depending on the type of screen.

Manual method to repair a damaged pixel

This method is very effective and truly consists of the following:

• Get a cloth or a slightly damp towel. Slightly it means you should not run water from the cloth at any time. Moist, not wet.
• Locate and memorize where is the pixel that is failing, and then completely turn off the LCD screen. If it still doesn’t work visit ask a managed it service provider san antonio to help you.
• With a fingertip, apply gentle pressure to the area where the pixel is damaged, using the damp cloth. No more pressure because you can damage other pixels, exerts a light pressure with slight movements of the thumb which is defective.
• While performing this task, turn on the screen so that it lights up with a strong image as much as possible. Remove the pressure and the cloth, the pixel should be working.

This method is effective in 80%. Give it a try and let us know how it works for you.
