Preventive maintenance can detect recurring failures, reducing dead spots and stops, increase equipment life, reduce repair costs, identify weak points in the installation of a long list of benefits.

On the computer, preventive maintenance is the periodic review of certain aspects of both hardware and software on a PC. These influence the reliable performance of the system, the integrity of stored data and an exchange of information right at the maximum speed possible within the optimal configuration of the system.

Within the preventive maintenance software exists that allows the user to constantly monitor the status of your computer, as well as minor adjustments in an easy way.

Preventive maintenance is generally occupies in the determination of operating conditions, durability and reliability of equipment in question this type of maintenance helps to reduce the times that can be generated by corrective maintenance.

While preventive maintenance is considered valuable for organizations, a number of equipment failures or human error when performing these maintenance processes. Planned preventive maintenance and planned replacement are two of the three policies available to service engineers.

The first objective of maintenance is to avoid or mitigate the consequences of equipment failure, achieving prevent incidents before they occur. Preventive maintenance tasks include actions such as change of worn parts, changing oil and lubricants, etc. Preventive maintenance should prevent equipment failures before they occur.

Preventive and corrective maintenance of software. The software maintenance software maintenance is one of the most common activities in software engineering and process improvement and optimization of software after delivery to the end user as well as correction and prevention of defects. Software maintenance is divided on two occasions: to prevent and correct. Preventive Maintenance software. Corrective Maintenance software.

Preventive maintenance software. Review Installation by Setup. Defragmenting your hard disk. Liberation of RAM. Freeing up space on HDD. Run Antivirus. Backup. Scandisk.

* Checking Installation by Setup. Consists of a review that is done by directly entering the menu on the Setup wing detecting units connected computer. By this you can detect any fault in connectors.

* Defragmenting your hard disk.

Disk fragmentation happens after the operating system has written different versions of the files several times, ie, a file after being modified to be saved does not occupy contiguous memory addresses on the hard drive, the defrag takes care to accommodate the files in contiguous memory addresses.

* Liberation of RAM.

Deleting files generated by the applications installed on the computer and no longer used, temporary removal, lost files, empty folders and shortcuts invalid records that have a path that no longer exists. RAMBoost 2.0, constantly monitors the state system RAM, freeing when you reach a certain threshold and thus optimizing the performance of your PC. Windows XP comes with a command line tool, called ClearMem, freeing up RAM and properly manage the resources, optimizing the paging file. WinRAM displays a graph of the state of the RAM, the percentage of free space and the occupied. Free

* Backup.

This procedure is to perform a data backup through the backup application. Route Cobian Backupcreador and backup manager. Easy to define the backup type normal, incremental or differential, the type of compression, encryption and exclusions. Advanced features such as task definition pre-and post-copying or performing other tasks with user credentials. The Tools menu hides more utilities: translator interface, decompressor, a utility repairman erased and permits among others.

* Scandisk.

* It is a software developed by Symantec, later acquired by Microsoft, to incorporate it with their operating systems MS-DOS. Scandisk is used to check on the computer both the integrity of the physical surface of your hard drive as the integrity of files stored in it. Examines the physical surface of the disc and is very effective for detecting file system errors. Reinstalling OS. Reinstalling programs, applications and Office. Reinstalling

* Reinstall operating system.

For some reason your operating system does not start or has failed. Failure of any reason that can not be repaired, this brings us to proceed to reinstall your operating system.

There are several processes that must be performed before starting a preventive maintenance Cie. to determine the proper functioning of the components. These are:

* If you have installed multimedia, can be tested with a music CD, this determines that the speakers and the unit are good.

* Perform a test to any installed peripherals. It is better take a while to determine the correct operation of the computer and its peripherals before you start dismantling equipment.

* We must be cautious with the handling of system screws when disassembling. The screws are designed for all points. It is very important to differentiate are those who are short of medium and long. For example, if you use a long screw to mount the hard disk, you run the risk of damaging the internal card of the same.

Preventive maintenance, in 7 steps

Internal cleaning of your computer:

Can be used for such cleaning appliances, a small vacuum blower or especially with a small brush. Special emphasis near the microprocessor and the Source.

Review internal PC connectors:

Sure they are secure and not loose. Check also that the expansion cards and memory modules are connected.

Clean PC Monitor:

It is recommended to uncover the PC monitor just in case repair is to be stored off because after a lot of energy that could be dangerous, if not the case, one blowing air in through the vents and clean the screen and the filter screen with a dry cloth that leaves no residue or lint.

If it is an optical mouse, always keep clean the pad (or pad where the mouse is used, that is valid for any type of mouse) and avoid having particles that obstruct the lens.

The drive:

By having all of them with a laser device is not recommended to open them if you are not qualified to do so. There are discs specially designed for cleaning lenses of these units.

The outer surface of the PC and peripherals:

It is recommended for this task a cloth moistened with liquid soap or a special substance containing no solvents or alcohol by its abrasive action, use it again after a dry, lint-free cloth.

The issue of software you have installed the PC and also requires maintenance is something that comment apart by the breadth of the subject.

Cleaning the PC

Isopropyl alcohol:

It is generally used to clean plates and tends to dry faster and does not stain as well as not having a strong odor. It also removes maimed you may have our cards or PC.

They are used to disassemble and assemble our PC at the time of internal maintenance well as for motherboards remove and refit.

Screen Cleaner:

Used to clean your monitor after or before performing maintenance on our PC.

Cleaner circuits:

It is used to clean internal PC cables so they are not damaged.

Compressed air

This tool is used to make internal cleaning the PC, to strip from dust, is also used in cleaning the power supply, monitor, keyboard, mouse and other parts of our PC.


They are used for cleaning usually inside the PC these brushes are camel hair you long for lint-free, can also be used for keyboard, mouse, etc..
