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.

Laptops are gaining in popularity these days. Almost everyone is carrying one now either for work or entertainment. Laptops with the latest technology are introduced to the market everyday and these new laptops come with a huge price tag. However, that does not mean you cannot get a good and cheap laptop. I have put together a guide that may help you out in your hunt for a cheap and good laptop.

Buy cheap laptop with older technology

Rapid advance in technology makes it meaningless to buy the latest technology at a high price. When laptop with wireless capability first came to the market, a unit with this technology can cost up till US$2500. NOw after 2 years, you can get a relatively fast centrino laptop for less than US$1000

Buy used or refurbished laptop
The depreciation of a laptop value is so high, that after one year in the market, a laptop can easily lose half its value. So if you are looking for a cheap laptop, look for one which is close to one year old. Not all used laptop are in bad condition. You will be surprised to find that some used laptops are still in good condition because their owners are power users or gamers.

Buy laptop from power users or gamers
I like to buy electronic gadgets including laptops from hard core power users or gamers. Let me share with you why. Gamers or power users usually require the latest and most powerful technology to run their games or power hungry applications. They often will not settle for second best. They also have the tendency to chase after the latest technology. So after one year, they will be bored of what they have and will look to sell off their laptops so that they can buy a new one. Now if you are looking to buy cheap laptops with up to date technology and you happen to have friends who are gamers, do ask them if they are looking to sell off their laptops. Who knows, maybe you can buy a good and cheap laptop from them.

Scan through gaming forums and local gaming community
if you do not already have friends who like to play computer games, then scanning through gaming forums on the internet is another way to get good and cheap deals for used laptop. Internet makes it easy for you to do this. Go to google.com and start searching for gaming forums. Visit each and everyone and see if they have a Trading Section. You will definitely find many post from gamers looking to sell their gaming laptops.

Scan through local bulletin boards
Do scan through local bulletin boards near you for cheap deals on laptop.Especially if there are software companies around the area. Software companies do offer their used computers or laptops for sale when their software projects end. I personally had gotten a few good deals for my family and friends.

Look for cheap laptop with at least 512mb memory
This is especially important for used laptop. If the processor speed is slow, then having more memory can compensate for the lack in speed. In fact, The size of memory plays a big part in determining how fast a laptop runs an application. Just by increasing the memory size, you can see a huge difference in speed. A cheap laptop with at least 512mb memory can run most non graphic intensive application easily.

Get cheap laptop from reputable manufacturer
This is very important because if you are buying used laptop, then the chances of requiring servicing is higher than a new laptop. So if you buy from a reputable manufacturer, you will save alot of trouble and time if your laptop do require servicing.
