It is very important to check a used computer thoroughly before buying it as it may lead to problems in the future. A hard drive will not show any outward signs but may be deteriorating. The same way the needle can suddenly slip and can cause scratches on the disc ultimately leading to memory loss as used computers can fail any time. If they are checked, the faults which may occur can be known. Let us first see the possible faults which may occur while purchasing a used computer.

Hard disk failures can happen due to heavy wear and tear over a period of time. The read and write heads of a hard disk are used to retrieve or recode data stored on the hard disk with the help of a disk platter rotating at a high speed. Over a period of time the risk of failure or malfunction of disk increases. Faulty sectors of the hard disks can be found out only if a full surface scan is done on the used computer. The scanning time depends on the capacity and size of the hard disk of the used computer. Many skip this procedure due to the time consuming process of scanning the whole disk and end up purchasing a used computer with a faulty sector.

Monitors need to be checked for any faults. The malfunctioning of a monitor is called a “dry joint” which results in the monitor not working after getting warmed. This can be checked only if the monitor is made to work for at least 20 to 30 minutes after switching on the computer.

Next is to look for any possibilities of the central processing unit getting freezed. Normally all the central processing units have a fan and heat sink for keeping the unit cool. Over a period of time the fans may not work properly due to the accumulation of dust and dirt resulting in over heating of the central processing unit and even leading to stopping from functioning. While buying a used computer the fan needs to be checked and if any abnormal sound is heard, it is not good for purchase.

The used computer may have a higher possibility of getting crashed and freezed due to the usage of the operating system for a good number of years. There may be a cache or RAM fault due to the over exposure leading to loss of data. To increase the performance of the computer and to avoid crashing, the operating system of the used computer can be reinstalled with a new operating system or a fresh one.

While checking the used computers for any faults, it is good to disconnect the network connection if any present before performing the tests. Also it is advisable to check the drives like the CD or DVD by opening and closing them and also playing something on the drives to see how they work. Monitors of the used computers can be checked for the resolution and brightness by trying different options of color, settings and so on. To check the hard disk size the CMOS setup can be gone through and to verify the speed of the processor, cache and RAM the pause button is pressed when it appears on the screen during the booting process. To check the booting process, the computer can be turned on and off a few times and seen how it responds. Checking should be done to see if all the passwords are erased before purchasing a used computer.

$Consider the printer’s DPI (dots per inch) capability, which is the resolution at which it can print photos and documents. The higher DPI (dots per inch) you have, the better quality you will have in either text or photo printouts.

$Consider the cost of ink. When purchasing a new printer, take a moment to compare prices among ink cartridges and make sure that you can afford frequent ink purchases if you plan to do a lot of printing.

$Take a look at the connector and make sure it’s compatible with your system. Most new printers connect via a USB port. Older ones connect using a parallel port, which is not commonly found on new PCs.

$When looking at the cost of ink, also look at the number of pages a single ink cartridge can print. If the page count is high, the cost of the ink may be reasonable. If the page count is low compared to other similar ink cartridges, you may want to select another printer that offers a better performing ink cartridge.

$Check out the warranty. All new electronics, including printers, carry a manufacturer’s warranty. Depending on the company, warranties can be valid anywhere from 90 days to 1 year and may include defects in material and/or workmanship. If your printer fails to perform correctly and develops a problem while under warranty, you will be glad that you saved the paperwork. Always keep the original purchase receipt and warranty information relating to your purchase.

$Buy from a name that you trust. When shopping for any item, it is best to purchase from a manufacturer that you know produces a quality product and especially when it comes to a substantial electronics purchase.

$Consider the size and weight of the printer. This is important for both cleaning general convenience. If your desk is small, you may not want a bulky printer taking up most of your space. At the same time, you may not want to lift on a heavy piece of equipment when cleaning your work station. A lightweight and compact style may be better, especially if your office is at home.

$Make sure that your computer is capable of running the printer software, which means it may require a specific processor type and speed, available memory, etc.

$Make sure that the printer you purchase has all of the features and capabilities that you need. For instance, if your primary goal is to produce realistic photos and you also plan to print written documents from time to time, consider the purchase of a photo printer. You can change the quality of printing to suit either images or documents or even a combination of both if you plan to print photo newsletters.

$Make sure that the printer has all of the necessary connector cables and that you will not need to buy any additional hardware prior to finalizing your purchase. If you need to purchase a USB cable, which is often the case with many new printers, you will want to purchase it at the same time to save on shipping if ordering online or having to make a special trip if you purchase locally.
