10 reasons for a computer failure

What are the most reasons for a computer failure and how to prevent it?

The average life of a PC or Laptop is 3-4 years yet a computer's life can be cut down to a fraction of that amount if the machine is expected to work in less than perfect conditions.

Yet the majority of causes for a hardware computer failure can be prevented by adhering to some simple steps:


1. User errors – Any tool is only as good as the person who uses it and computers are no different. Actions such as not powering down properly, skipping scan disks or continual button pushing while a computer is processing can damage a computer's hardware, particularly drives and processors. Always follow the correct guidance in using a computer machine.

2. Faulty manufacture –It seems there are an almost infinite number of manufacturers and assemblers making computers and while some have vast experience and resources, others are no more than two guys in a garage so it is not surprising that an increasing number of computer systems are faulty when bought.

3. Bad upgrades - It is not just computers themselves that are victims of bad person using it, upgrades by inexperienced computer fitters can cause horrendous problems. Faulty add-ons such as RAM can kill a processor instantly, also attempting to ‘overclock' or interfere with a processor can often lead to a fatal melt-down.

4. USB Device Mishaps - It seems everything can be plugged into a USB these days. However, it maybe that your USB device is not suited to the operating system you use or it may be faulty leading to a fatal short circuit.

5. Power problems - Power surges or unexpected power cuts can not only cause instant loss of data but can fry a processor. It is not just power from the grid that causes problems either - lightning can surge through cables (even phone or network or external devices with external power and connected to your computer wires or external devices with external power and connected to your computer through USB ports)  frazzling your system and so can static.

6. Dirt/Dust - A dusty environment will clog a computer and block cooling vents causing a computer to overheat. Dust can also contain conductive material and particles can stick to circuit boards and cause a short circuit. A cloud of dust can also explode if it comes into contact with a source of ignition (like a computer). Even home computers if not properly cleaned can succumb to problems caused by too much dust.

7. Water/fluids - Of course computers are electrical and with all electrical equipment, computers and water do not mix, just one spilled cup of coffee could see the end of your PC.

8. Heat -  Processors can run exceptionally hot and if a computers cooling system is inadequate (because the machine has been upgraded, overclocked or just clogged up with dust and grime) it will only be a matter of time before it packs up for good.

9. Cold -. Just as with heat, computers don't enjoy the cold too much either. Processors will not operate at all if the operating temperature is too cold as condensation inside the machine can freeze and expand damaging the processor and electronics.

10. Knocks/bangs - Computers are sensitive machines, simply moving a PC (Desktops usually) to another room can cause havoc, disrupting the delicate circuitry and hard drives. Dropping a computer or severe knocks and bangs will permanently damage the circuits and processors or dislodge wiring.
