New PC desktops and all-in-ones can provide the optimum performance for browsing the Internet, running applications, and playing video games. However, the cost of a new computer can also be quite high, and buying a new PC desktop or all-in-one every few years is not always an option. Fortunately, buyers have a large selection of used PC desktops and all-in-ones to choose from, many of which can deliver the power needed to handle everyday use with great performance.
Begin by considering the RAM and central processing unit of a machine. These determine how many programs and tasks can be run at the same time and how quickly actions are performed. It is also useful to look for computers with powerful graphics cards if films are watched on the machine or 3D games are played.
Used PC desktops and all-in-ones can be purchased from computer retailers and occasionally from electronics shops. Many used computers are also available online. These can be found in classified advertisement from private sellers and in marketplaces like eBay.
Components of Used PC Desktops and All-in-Ones
In some cases, good quality used PC desktops or all-in-ones that can still deliver power can be difficult to find. Buyers may need to replace small components, reformat the hard drive, and perform other actions to restore the unit to a working condition.
Processors for Used PC Desktops and All-in-Ones
The central processing unit (CPU) is the command centre of a computer. It interprets instructions from the user to make programs available and performs other actions. CPUs are built with cores, which determine their speed and performance. Video games and operating systems demand a multi-core processor. For a machine that can still deliver power, choose a used PC desktop or all-in-one with a quad-core processor to avoid slowdown and lag times during use, or consider upgrading this component after purchasing the used computer. Remember to factor in any upgrades when calculating the total price of the unit.
RAM for Used PC Desktops and All-in-Ones
The RAM (random-access memory) of a computer determines how many programs can be run at once without slowing down the machine. It also affects the time needed to boot up a PC desktop or all-in-one. The minimum amount of RAM needed to get any serious power from a computer is 2 GB. This allows multiple browsing tabs to be open and enables users to play video games without too much trouble. Buyers who wish to do photo or video editing, or play games with advanced 3D graphics, should look for PC desktops or all-in-ones than can handle 6 GB or 8 GB of RAM.
Motherboard Support for Used PC Desktops and All-in-Ones
Buyers who are considering upgrading their RAM after buying a used computer should be aware of the motherboard because it determines the amount of RAM that can be used. Motherboards can be either dual-channel or triple-channel. Dual-channel motherboards can support 1 GB, 2 GB, 4 GB, 8 GB, and 16 GB, while triple-channel motherboards support 3 GB, 6 GB, 9 GB, and 12 GB. However, bear in mind that motherboards have limitations. For example, not all dual-channels can handle 16 GB, so it is important to review the specification for the used PC desktop or all-in-one before making an upgrade.
Graphics Cards for Used PC Desktops and All-in-Ones
Graphics cards handle the speed and performance of videos and games on a PC desktop or all-in-one. Dozens of new cards are produced each year to keep up with the advancements in video resolution and game graphics. Although computers are designed with built-in graphics cards, the power and quality of these units can vary greatly. For fast video and good quality gaming, look for a used machine with at least a 1 GB graphics card. Some high-end used computers have a 2 GB card. It is also possible to purchase new graphics cards for a used machine.
Hard Drives for Used PC Desktops and All-in-Ones
The hard drive capacity on a computer determines how much information can be stored on it. The amount of storage needed by a buyer can vary greatly depending on the amount and type of software used. Digital artists and serious gamers may need a computer with a 1 TB hard drive, although most buyers should find 500 GB to be more than sufficient for their power needs. Hard drives also have a speed rating that determines how quickly data can be saved and transferred. Hard drive speeds are rated in RPMs. Look for used PC desktops or all-in-ones with hard disk drives of 7,200 RPMs to deliver real power.
Factors to Consider When Buying Used PC Desktops and All-in-Ones
There are several factors to consider when buying used PC desktops and all-in-ones. Consider the cost and effect on performance of upgrading to a new operating system and ensure that the software on a machine is licensed. Also, consider the possibility of repairs and cleaning.
Software and Operating Systems for Used PC Desktops and All-in-Ones
One of the most important factors to consider when buying a used PC desktop or all-in-one is the operating system (OS) it uses. Most secondhand computers have a Windows OS installed, although it may be two or three generations old. To get the best performance from a machine, it is useful to have the most modern OS available. However, in some cases, these can be expensive and eliminate some of the cost benefits of purchasing a used computer.
It is also worth checking to make sure that the software and OS on a used PC desktop or all-in-one is licensed. All computers with Microsoft OSs installed since Windows XP was released have a product key that is shown on the external casing of the machine. The OS is also included on the machine's start-up disks, which should be included in the sale of the used PC desktop or all-in-one. The seller should also be able to provide the disks for all additional software.
Repairs and Maintenance for Used PC Desktops and All-in-Ones
Many used PC desktops or all-in-ones have been used extensively, so may require cleaning, reformatting, or other work to restore them so that they can still deliver power and a good performance. When setting up a new computer, clean it as much as possible. If a PC desktop is purchased, open the external casing for the tower and remove any dust and dirt that is inside the machine. Run the Disk Defragmenter in Microsoft Windows. Also, consider purchasing virus protection software to guard against malware. It may even be worth taking the machine to a technician for a full system check if the seller has not already done this.
Buying Used PC Desktops and All-in-Ones That Can Still Deliver Power on eBay
A wide selection of used PC desktops and all-in-ones that can still deliver power can be purchased from the sellers on eBay. Shop for these machines by typing keywords into the search field on the home page. For example, enter "used dell desktop" into the field to see all items tagged with those terms. You may add new keywords on subsequent search results pages to refine the listings further.
Read the Item Description
Take the time to read all of the information about the PC desktop or all-in-one carefully before committing to a purchase. Look for a specification sheet to learn about the machine's processor, RAM, graphics card, hard drive capacity, and other details. Check the description of the computer provided by the seller and compare it with all available photographs. Determine which items are included in the sale and be aware that some machines are sold without a screen, mouse, or keyboard. Be clear on the price of the item, and factor in the delivery charges and any necessary upgrades into your calculation of the total cost.
Read the Seller Feedback
Ensure a positive transaction by examining seller profiles. Look for positive feedback ratings and compare them with the number of transactions sellers have completed to find the most experienced and reliable eBay users. You may also view comments left by previous buyers. These can provide additional details about the seller's performance, such as the quality of communication and how well packaged the items were during delivery. Where possible, look for sellers that specialise in used PC desktops or all-in-ones as they may be more experienced in whether upgrades are needed to deliver power.
Purchasing used PC desktops or all-in-ones can save buyers considerable amounts of money. There are many items on the market that are in excellent condition and can still deliver power. To find good quality pre-owned machines, consider the processor, RAM, hard drive capacity, and graphics card. The processor responds to commands from the user and is responsible for performing vital actions in the machine. Choose a quad-core processor for the best performance. RAM affects how many programs and operations can be conducted at once. Look for used PC desktops or all-in-ones with at least 2 GB of RAM. Check the motherboard before considering an upgrade.
Graphics cards affect the appearance and speed of videos and games on the system. Buyers looking for strong performance should choose at least a 1 GB card. Clean a PC tower and run the Disk Defragmenter to clear space on the machine if the seller has not done this. It may be worth hiring a technician to examine the machine, if this is cost effective, before purchasing the PC desktop or all-in-one.
Used PC desktops and all-in-ones can be purchased online at eBay, which has listings from commercial and private sellers. Perform the necessary research before buying and look for items at low prices that have excellent performance.
