Computer safety and maintenance

* What is the maintenance for PC? 

It is the care that is given to the computer to prevent possible failures, should take into account the physical location of the equipment, whether at the office or at home, as well as special care when not using the computer. 

* Types of maintenance for the PC. 

Preventive maintenance for PC. 

Is to create a favorable environment for the system and keep clean all the parts of a computer. The largest number of faults that have the equipment is dust buildup on internal components, as this acts as a thermal insulator. 

The heat generated by the components may not adequately dispersed by being trapped by the layer of dust. 

The fat and oil particles that may contain ambient air mixed with dust, creating a thick layer of insulation that reflects heat back into the other components, thus the lifetime of the overall system is reduced. 

On the other hand, has conductive elements that can create short circuits between the paths of the circuit boards and cards perefericos. 

If you want to prolong the useful life of the equipment and make repairs free stay for many years must be cleaned frequently. 

* PREVENTIVE MAINTENANCE AL CPU 

The surrounding environment is a personal computer wing it a magnet for dust and this is what most affects failures causing small electronic components, accumulated dust reduces the efficiency of the cooling fans and can act as an insulating blanket that retains heat and irradiation does not allow this to move away from the components. 

Emphasis should be placed on the following areas: 

Motherboard: 

Tools should be used as a clean rigid bristle brush, a vacuum cleaner and degreaser. 

CPU fan: 

This can accumulate nearly as much dust as the source of power, and as the CPU generates too much heat, it is important to keep clean the fan to keep good cooling capacity. 

Expasion slots (ISA, PCI and AGP): 

You should keep dust from these slot ensure good quality connection. Once removed excessive dust can apply a product that has just removing the dirt from the card and usually containing degreasing substances; this serves to prevent small grease residues cause the early accumulation of dust. 

* Reasons for PC maintenance * 

1.-Clean and organize your hard disk frequently fills informations because the system files are deordena and overall performance decreases. 

2.-Contents periodically scan the hard to correct disk errors or failures because a file cleanup and defragment your hard drive unprotected the informations will be more and more difficult to recover. 

* Maintenance should be done in three basic aspects: 

* Diagnostics: 

1.-time hard disk errors occur, the data is disorganized and references become obsolete. 

2.-These small problems accumulate and slowly put the operating system, and software system failures occur more frequently and operations on and off it takes longer. Should perform periodic maintenance. 

* Should be included in routine maintenance these tasks: 

Solving altered sectors, file cleanup and disk defragmentation duro.Exploraciòn hard disk to check for errors 

cleaning: 

To ensure optimal and efficient performance of the computer, we must keep clean and organized. 

We must remove the old programs, and programs not utilicemlos lad drives to free up memory and reduce the possibility of conflito system. 

* Defragmentation: 

Of all the components of a PC, the hard disk is the sensible more and what else requires careful maintenance, we use Scandisk or another utility to check for errors on the hard disk. 

* SAFETY PRECAUTIONS WHEN SERVICING THE PC 

These measures seem basic but it is vital for the security of your computer equipment and your personal safety: 

* Before opening any review it is necessary to detect possible fallasd, ppppor which you have to turn the computaddora and pprobar todaas and every one of the applications, review the floppy disk and CD-ROM. 

* Verify that each one of the keyboard keys work properly, both the mouse and the buttons to move without any problem. 

* Do not forget to turn off the computer and unplug the power cord from the power supply before removing the screws and take note of where the off. 

* Remove the screws and pack the boat for photographic roll-fico (so avoid losing screws), make sure to use the proper screwdriver. 

* Remove the cover from the computer if the CPU is mini tower lay him to work comfortably and safely. 

* Before removing any component, carefully observe the inside of PC, note the placement of the cards, when preventive maintenance is finished place them in the exact location where the sack. 

* Once taken notes ls little details necessary to put ñthe antistatic bracelet to avoid damage to any card. 

* When removing the card and cleaned the place lies inside an antistatic bag, same for all cards. It is recommended that you do not remove the hard drive, microprocessor and power source. 

* The workbench be located in a suitable place, to avoid running the risk that retirees fall enclosure components (cables, expasion cards, etc) 

* Proper lighting is essential to observe the areas to be cleaned, on par with a better identification of the components of the computer to avoid confusion when connecting different cables inside the system.
