Investing In A Used Computer? Read This First
Buying a used computer can save you a lot of money but you need to be sure to check the computer thoroughly prior to buying. There is nothing worse than spending a whole lot of time getting a new computer all set up, customizing it to your liking, loading all your software on it and transferring all your files to it and having it fail soon after. Fortunately there are some simple steps you can take to reduce the risk a used computer being a lemon. Buying a used computer is also a wonderful way to get a machine loaded with upgrades such as a USB TV tuner for very little or for free.
Probably the worst thing to have fail on a computer is the hard drive because you risk losing your data. The problem with inspecting hard drives is that many of the failures are due to mechanical issues that cannot be detected without opening the hard drive case is not recommended. So a hard drive that will failure very soon may not show any outward signs that it is deteriorating. Hard drive failures can be caused by internal issues such as the needle slipping and scratching the disc which will lead to failure. Some hard drive failure is due to mechanical failure others are due to ordinary wear and tear. The read and write heads of a hard disk are used to retrieve and write data to a hard disk that is rotating at a high speed. Over a time the risk of failure or malfunction of a hard disk increases.
Some potential hard disk failures can be detected by performing a full system scan. Certain bad disk sectors are easily detected and repaired by performing a full system scan. The scanning time depends on the capacity and size of the hard disk of the used computer. A full disk scan is often impractical to perform before buying a used a computer because of the time it takes. It is not advisable to skip this step.
Another component to inspect is the central processing unit (CPU). It is possible for the CPU to freeze. The primary cause of CPUs freezing is overheating. CPUs have a fan and heat sink to keep the unit cool but the fan can wear out or not function properly due to the accumulation of dust and dirt which can result in the CPU overheating. It is fairly easy to check if the fan is functioning properly by listening to it and looking for excessive dust. A properly functioning fan should be a consistent, low hum. A fan that is not working properly will often emit an uneven sound in volume or tone.
If you are buying a monitor it should have crisp colors and be bright. Dull or muted colors are signs that a monitor is near the end of its life. Monitors should not flutter or have lines and should not make more than a very low hum. The health of a monitor is even more important if the computer has a USB digital TV tuner.
A computers operating system should be checked as well. Over time operating systems can slow down due to programs being added and deleted from the system. The registry can also become cluttered with deleted programs. Unless you are knowledgeable with such things the best way to test the operating system is reboot the system a few times. A computer that takes an excessive amount of time to boot up can be a sign of an operating system that needs attention. Probably the best option after you purchase the computer is, if you are comfortable with it, to reformat the hard drive and reload the operating system and all drivers and programs.
All other hardware should also be checked. This includes, devises like CD or DVD drives, the drawers should open and close smoothing and you should be able to read data from a disc and if they are writable drives you should be able to write to a disc. Other items that should be inspected are the USB TV tuner card, mouse and keyboard.
