Any computer system is a massive investment and a multipurpose tool that has to be kept functioning to get the maximum mileage out of. Maintaining the computer at its best has the advantage of getting optimum performance and maximum productivity. A computer, like any other piece of machinery, has a few moving parts and some parts that generate heat. In addition, there are also some software parts which, like their mechanical counterparts, need to be looked after.
The computer has some mechanical moving parts like the fans. These are used to remove the heat build-up from inside the cabinet or the housing of the computer. Most of these fans are the brush-less type and use self-lubricating bearings that mostly do not need maintenance. However, all environments are not same, and there could be dust and grime build-up that could clog the bearings and make the fans run slow.
Slow running fans will sometimes cause more noise and also will not be able to circulate enough air to remove the heat build-up. This may lead to several malfunctions such as sudden freezing of the computer. It is therefore, imperative to open up the case and use a strong vacuum cleaner in blower mode to blow out the accumulated dust and grime.
The CMOS battery that keeps the clock running even when the computer is powered off has a life of about five years. The first signs of age will show up when the computer starts to lose time. Replacing the battery will usually solve the problem.
Windows users will have to use some sort of software to clean up the Registry. When adding or deleting software from the computer, the Windows Registry System often retains junk, and, which later makes the system malfunction. More modern operating system such as Linux and Macintosh do not have this malady.
Another software cleanup tool, required by Windows users, is the disk cleanup and defragmentation. When Windows stores its files, it often distributes them all over the hard disk. This causes the whole system to slow down or even crash. Again, this is a Windows alone malady that can be overcome by using more efficient operating systems.
Computers connected to the internet and sharing files between other computers, run the risk of contracting and becoming affected by virus and spywares. It is recommended that some good anti-virus software be installed to detect, warn and eliminate potential virus before they can cause harm, such as Norton Antivirus, Kaspersky Antivirus, Bitdefender Antivirus etc.
Periodic checking of the hard-disk and marking off the bad sectors will prevent expensive data loss. Several software are available that could be used to warn of potential danger while checking the hard-disk. Backup important data and plan for a new hard-disk as early as possible.
Power interruption in the middle of an important task may cost you several hours of unsaved work. Another problem that a sudden power interruption may cause is hard disk failure, especially if it was reading or writing at the time. It is recommended to invest in a good quality battery backed uninterruptible power supply to act as backup source of power, until you could shut down the computer in the specified manner. I also suggest you to do timely backup of your data. You might find this post useful:
