the maintenance of computer equipment is very necessary, to extend the life of our equipment, it is important that as common users learn to do basic maintenance. And if I tell you that you can also do it with household objects saving costs and facilitating preventive maintenance.

Let's count the cost of computer tools that we will replace with household objects, for basic maintenance of computer equipment, note that the tools are expensive but their effectiveness is already proven by experts, however, the purpose of this document is to provide options for those who can not afford the tools, I should also note that not all are replaceable in full.

There are two types of hardware maintenance:

According to (Armero Kreisberger).

Corrective maintenance: it is when there is a failure or inconvenience in the proper functioning of my computer and this must be solved.

Preventive maintenance: to maintain the computer clean making sure that it is not the dust and the sulfation or corrosion what damages our PC.

Prices of the tools when replacing:

Blower: 70$.

Sq 180cm3: 20$

Hagibis Cleaner Multi 4 1: 47$

A Phillips screwdriver: 5$ (not replaceable).

For home use:

Hair dryer.

White rubber eraser.

Hair dye brush.

Phillips screwdriver.

Let's start with the hair dryer, these come in many makes and models, but basically they can help us access these inaccessible parts of the board, where the dust lodges, and without disassembling anything, just by disconnecting the pc from the power supply, removing the cover, and blowing the dusty areas. (Recommendation hold the computer fans so they don't spin while blowing).

Eraser: it can help us to free sulfation and partner, that lodges on the pins of our RAM memories, or on our graphics card, very useful!

Hair dye brush, well your mom, your sister or your thick sure use one, and then discard it, it comes in the boxes and you can give it a long time of use, to remove dust from our hair box.

Phillips screwdriver with magnetized tip, I do not recommend you to replace this tool, for several reasons, but the first is that it is not so expensive, and the second is that using a kitchen utensil as are the, is very risky and can damage the integrity of the screw, plus the magnetic tip screwdriver will keep the screw held to prevent it from falling on the plate. (note it can also help to pick up previously dropped screws).

Conclusions:

Extend the life of our computer, it is important and knowing the costs, do not have to know much about computers to simply do preventive maintenance, which keeps our pc in good condition, I hope you have been helpful my post.
