BASIC TROUBLESHOOTING TECHNIQUES

Almost no one is exempt. Like life itself, computers bring happiness, but also complications. There are several moments where many want whizzed through the air the computer that had so happily acquired a few months ago. That usually happens when problems begin to arise, and it seems that everything was over. Computers, like all man-made element, are not perfect. They tend to fail Especially if you do not do them regularly serviced. PCs are designed to last, on average, about 10 years. Sure, there may be gains to be left obsolete long before, but the duration of its various components is estimated to be mentioned that decade. According to statistics from different sources, the main cause of the problems of a computer (80%) is the user. Those who have little idea usually no minimum maintenance tasks that would bring good health to the system.

 

These are the main problems:

1) Decreased performance PC.
 
It's the biggest complaint from users. There are many reasons to explain it. The most common: lack of maintenance. Fragmented data, corrupted registry, spyware, and a lot of programs running unnecessarily. Simply set what you have installed, delete the unnecessary and take over the operation of the PC can be gained in speed and performance.

2) unexpected closures of programs, screens freezing and errors
 
Many of these problems are caused by spyware or spyware. While reach and constantly update with having an anti-spyware program, the causes can come on the other hand, such as the lack of proper drivers for the hardware installed. It would also be a good idea to increase the virtual memory of the PC, to better take advantage of the RAM installed.

3) The computer automatically restarts or turns off by itself.
 
The problem may come from dirt inside the cabinet, or a blocked fan. The computer can not cool, and the only way is fading. If you feel too hot from there, would be good to clean the fan.
If the problem persists, it may be failing power supply, or even would be good to review the internal cables to see if they are connected.

4) Strange noises and vibrations.
 
Hardware problem. Of all the parts of a computer, one or more are not doing as it should. Cables can be inside a loose or bad plate bolted or otherwise. You need to open the cabinet and set it can happen. As can be more complex, it is the perfect time to call for service.

5) home page, the search engine or the browser just changed.
 
It is also called "high-jacking". There is a spyware installed, whether it came from a social network or an email. The spyware installed a java script in the browser to change personal options. Run a diagnostic program can avoid service call.

6) Fall of the operating system

A system crash is a sudden and frustrating for a computer user problem, and has a number of causes, ranging from the sudden interruption of power to have an invalid operating system. Falls occur occasionally; however, if they occur frequently, the computer may need service.

7) Problems with CD / DVD

Dust and dirt may accumulate on the tray or slot CD / DVD, which can disrupt the ability of the scanner to read discs. You can also try cleaning the CD or DVD itself.

8) Problems with mouse and keyboard

Can also accumulate dirt and grime in the components of the mouse and keyboard, causing it to malfunction. Often clean inside the mouse and the keyboard to shake both devices continue to function properly.

9)Problemas with the video card

If you turn on your computer and nothing appears on the screen, it is possible that your video card is failing. Order a replacement or ask a technician to do it for you.

10) Windows fails to boot

Another common problem with computers is that Windows fails to start at the beginning, which prevents you access your files. If this happens, you can try to start your computer in safe mode or boot with the help of a CD system. If these options do not work, you probably need to reinstall the operating system with a Windows recovery disk.


11) Lock

If your computer stops responding to the mouse or keyboard, it is likely that your operating system is locked. Press and hold the power button to turn off the computer. Wait a few seconds and turn on the computer.

12) Slow Computer

Download malware or spyware may inadvertently slow your computer down. There are online programs, such as Spyware Doctor and Windows Defender, which will analyze your computer and remove harmful programs. You can also speed up your computer by removing cookies and temporary Internet files.

13) Unable to connect to Internet

The Internet connection problems can have a wide range of causes. Network cables connected improperly, an incorrect IP address conflict with firewall applications can cause connection problems.

14) The computer will not boot

If the computer will not start, it may be due to a problem with the power outlet. To test can plug another electrical device to see if it works. If the outlet is operational, the computer may need a repair.

15) Inability to delete files

Sometimes the computer does not allow you to delete files. That is usually due to a violation of the rights of trade, which means that another program is using that file as Aholic PC. The solution is to close the program that is using the file.

* 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.
