In today’s world, we all use computers. Well, most of us do, and the underprivileged are using it, maybe not directly, but indirectly. Somehow, even the tiger in the Indian jungle today relies on the computer to remain alive. Not that the fellow gets to use one. However, the environmentalists, the scientists, and all who care, keep their tabs on the guy through computers. Maybe even poachers do so. As far as Murphy’s Law goes, whatever can fail, will. So, the mighty computer can also fail, remember HAL?

In a computer, say a desktop, there are several working parts. They include mechanical, electrical, electronic, firmware, and software. As per reliability theory, more the number of components available, greater are the chances of failure. So, with five sciences present in the computer, failures do crop up sometimes or the other.

If you look closely at your computer, you will find some moving parts. These are called fans, which allow air circulation. While operating, the computer generates heat, and this has to be removed, which the fan does. Just as when you feel hot, you sit under a fan. Computer fans rotate at high speed, which causes a lot of wear and tear on their bearings. When a fan starts to make a lot of noise, it means, the bearings are degenerating, and it is time to change the fan. Failure to do so will cause additional problems due to heat build-up.

Heat build-up is a major headache for any machine, especially machines that have a sophisticated structure like computers. Heat causes the Electrolytic capacitors and heat conducting pastes to dry out, solder joints to fail, and reduces the reliability of all the electronic circuitry. This type of failure is very difficult to diagnose because of its intermittent nature. The whole computer may just freeze up and refuse to start, until it has cooled down. The power supply is the area where the maximum heat is generated, and the failure here, is also the most frequent. Therefore, if your computer has been acting strange recently, get it checked up.

Similar to heat, dust is also a great contributor to damage in computer moving parts. The sliding tray of your DVD drive may be malfunctioning because of dust entry. Dust entering the back of your display, may cause the high voltage generator inside to stop functioning. Some LCDs have Plasma back-lights, which also work on high voltage and are susceptible to dust. Fortunately, LCDs are changing over to LED back-light, which are more rugged. Mouse and track-balls are other devices, which choke on dust and lint. Frequent cleaning helps to increase their life.

Most people take their hard disk drives for granted, and never bother to keep backups. This is the biggest folly anyone can make. The hard disk drive is also a mechanical item, and is subject to wear and tear. It is generally quite rugged, but then there is a chance it can fail. Better to be safe than sorry, keep backups frequently.

Software is one of the most important parts of the computer, without which the computer is but a pile of junk. There are two types of software in use, the Operating System and the Application software. An Operating System should be efficient and unobtrusive. It should not require any maintenance, but there are some that do. Some need their registries cleaned or their hard disk space de-fragmented, on a regular basis or the OS may slow down or even choke. Some OS do not maintain their file systems with proper care, and malicious software (virus) can steal your data.

The Application software running on your computer should be from authentic sources. Unknown application software may be a wolf in sheep’s clothing, and could steal your data or cause a serious crash. It is always wise to use an Operating System, which does not allow unauthorized software to run and special anti-virus software to check for malicious software.

Therefore, it is highly recommended to update the anti-virus software before using the computer and scan the incoming emails before opening them.

Leaving the computer on is also not a good solution. It can create an excessive wear in mechanical circuits in the cooling fans and the hard drive motor. Frequently turning on and off the computer can also create problems in the motherboard circuits. These problems can be flexing and fatigue failure due to excessive temperature changes. It is a great practice to turn on the computer and turn it off at night or whenever you don’t use it. It is also highly recommended to clean inside the desktop to remove the dust that can create overheating in the system.
