BASIC COMPUTER MAINTENANCE
MAINTENANCE
One of the most common questions computer users ask is, How do I maintain my computer and keep it running great? A computer is a lot like a car...it costs more than you think it should, it starts going down in value as soon as you bring it home and it requires regular maintenance to keep it running smoothly.To properly deal with repairable systems, we need to first understand how components in these systems are restored (i.e. the maintenance actions that the components undergo). In general, maintenance is defined as any action that restores failed units to an operational condition or retains non-failed units in an operational state. For repairable systems, maintenance plays a vital role in the life of a system. It affects the systems overall reliability, availability, downtime, cost of operation, etc. Generally, maintenance actions can be divided into three types: corrective maintenance, preventive maintenance and inspections.
Preventive Maintenance
Preventive maintenance is the practice of replacing components or subsystems before they fail in order to promote continuous system operation. The schedule for preventive maintenance is based on observation of past system behaviour, component wear-out mechanisms and knowledge of which components are vital to continued system operation. Cost is always a factor in the scheduling of preventive maintenance. In many circumstances, it is financially more sensible to replace parts or components that have not failed at predetermined intervals rather than to wait for a system failure that may result in a costly disruption in operations.
Here are a few basic guidelines required. I Surge Protection: Power surges, spikes, lightning and brown - outs are all things that can literally burn up your computer and its peripherals. Save yourself lots of money in repairs by buying a decent surge protector (a.k.a. Power strip) for your computer and use it. A UPS (uninterruptible power supply), though slightly more expensive, is even better.
II Anti-Virus Protection:
Everyone should know about this by now, but we often see computers with either no virus protection at all, or anti-virus software that is badly out-of-date. Nothing can wreck your computer faster than a virus (except for may be electricity), but with a small investment in good anti-virus software and making sure you set it to update itself daily.
III Minimize the number of Software you install:
This is another thing many people overlook. Installing lots of programs on your computer is a lot like pulling a bunch of rowdy children together on a playground. Some of them may not play well together. A good rule of thumb is if you dont need, dont install. This is especially true when you surf the web. You will likely get bombarded with pop-up ads trying to get you to install all kinds of flee utilities they claim your computer cant live without most of these are spyware, adware and junk.
