subject: Computer Repairing in case of breakdown [print this page] Downtime causes millions of dollars worth of damage to computer systems around the world. Power related issues as it turns out, commonly causes the unexplained downtime, time-outs, and other networking glitches. The power source should be safe and secure. Make sure that the earth connection is properly working and the polarities of live and neutral are in order. A qualified electrician can easily test this and the little investment would save you from all future major repairs. If the earth's line fails and the stray current on the motherboard lack proper grounding, then it leads to component failure. Later this can turn out to be a costly repair.
Feed power to your computer though a line conditioner with uninterrupted power supply unit. computer repair This would ensure that in the event of a blown fuse and fluctuations in supply, you are able to shut down your computer without corrupting the operating system.
Place the Central Processing Unit in a well-ventilated place. The CPU generates a lot of heat and the cooling fans should dissipate this heat into the atmosphere. If hot air cannot escape and cold air cannot enter the system, overheating would lead to component failure. There should not be too much moisture around since there are components called "capacitors" that fail if too much of moisture is prevalent in the air. Dust is an enemy. It settles everywhere and forms a thin layer on the motherboard. The dust layer combined with moisture becomes a good conductor of electricity that can damage the components leading to failure. Periodically blow air through a vacuum cleaner to remove all that dust settling on the motherboard, Switching-Mode Power Supply (SMPS), and hard disk printed circuit board.
Avoid shutting on and off the computer too frequently. Every time you put on the computer, it heats up and when you turn off they cool down. This ultimately leads to thermal degradation of components due to frequent expansion and contraction. If you want to go for dinner while working on your PC let it run on minimum of resources. This would enable the system to maintain its optimum temperature, instead of cooling down and again reheating leading to thermal wear and tear.
Preventive maintenance is the best solution for the optimum utilization of component life. Modern hardware consists of few serviceable parts inside the computer. The rapid advancement of technology obsoletes the serviceable spares if any. It is advisable that the user take care of the key factors that can lead to failure of the hardware.
