If your computer has become slower over time, there are several possible reasons. In this three-part series, you’ll learn the primary reasons a computer isn’t reaching its full speed potential. First, we’ll examine the hardware-related reasons that might be preventing your computer from keeping up with your workload.

There are several hardware upgrades that can positively impact your computer’s speed:

1. Processor: If your computer is older, this is one of the likely reasons your computer isn’t satisfying your need for speed. The speed of the latest CPUs increases by a considerable margin each year. An older computer obviously has an older, and slower, central processing unit.

• Keep in mind, that a motherboard will only accept a particular “family” of central processing units. A processor upgrade might require the installation of a new motherboard in some cases.

1. Random Access Memory (RAM): While RAM does indeed have a speed rating associated with it, it’s the amount of RAM in your computer that is more important. Many computers have open memory slots that can be utilized to add additional memory. There is also the possibility of replacing memory modules with modules of greater capacity.
2. Hard Drive Speed. Not all hard drives are created equal. There are two basic designs utilized for modern hard drives: Hard disk drives (HDD) and solid state drives (SSD).

• Hard disk drives are mechanical and use one or more rotating disks to store information. HDDs operate at either 5,400 or 7,200 RPM, depending on the model. A slower speed drive has the potential to slow down your computer. There are a few models capable of 10,000 RPM, but these are quite rare and expensive.
• Solid state drives don’t have moving parts and are more reliable than hard disk drives. An SSD uses flash technology similar to the common USB stick. Solid state drives are more expensive than hard disk drives, but are considerably faster. The typical SSD is more than 10-times faster than the average 7,200 RPM HDD when it comes to reading and writing data.
• To save on cost, putting the operating system on a smaller SSD drive and storing the other programs and data on a conventional HDD is an great option.
• A hard drive that is near capacity can also hinder a computer’s speed. Your computer needs a fair amount of free hard drive space to operate at peak efficiency.

These are the primary hardware culprits to evaluate if your computer seems to be lagging in performance. Take a look at your processor, the amount of RAM, and the type of hard drive(s) in your computer.

Next, we’ll consider the impact software can have on the speed of a computer system.

The Differences Between Refurbished and Used Computers
 
There are many times when a new computer is either overkill or simply too expensive. Perhaps your needs or your budget are limited. If you’re interested in using a computer to surf the web, use a word processor or spreadsheet, and stay on top of your email and Facebook accounts, a new computer might be more than you need. A used or refurbished computer is a viable option.
 
It can be a little nerve-wracking to purchase a computer from a stranger on Craigslist. That’s what makes refurbished computers so attractive.
 
While there are no official definitions to separate ‘used’ and ‘refurbished’ computers, there are some generally accepted guidelines. A used computer is considered to be a computer sold ‘as-is’ by a private party. There is typically no warranty included. In most cases, no work has been done to the computer to bring it back to factory standards. You have little recourse if the computer develops an issue.
 
A refurbished computer is analogous to purchasing a certified used car from a dealer. The computer should be  put through a rigorous testing process, parts should be replaced as necessary, and a warranty included. A refurbished computer will be approaching the quality of a new computer at a lower price. It can be the best of both worlds.
 
The hard drive should be wiped clean, and the operating system is re-installed so there is ZERO user history. Refurbished desktop computers also often get a new mouse and keyboard (if not they should).  Any problems are  discovered and corrected.
 
This is very different than purchasing directly from the previous owner. A computer purchased on Ebay or Craigslist from an individual looking to sell might contain a history that you don’t want to be associated with.  Sometimes, people will hold onto a computer until a significant problem occurs and computer problems can be quite challenging to rectify. Spending money to purchase someone else’s problem might not be a good strategy. And, getting a refund may be difficult. Used computers can be a gamble.
 

Like anything else, purchasing a used or refurbished computer has both advantages and disadvantages. Understanding the pros and cons of purchasing a used desktop or laptop computer can make it much easier to reach the best decision. Good decisions can’t be reached with bad information.
 
Reasons to purchase a used computer:
 
1. Price: This is the most obvious advantage of purchasing a used computer – and the primary motivator for most people. Due to the “slow economy” many people and businesses are looking for used computers as a way to save money. It’s most likely the primary reason you are reading this article and considering a used computer. While older computers typically have lower specifications, they often provide far more capability than the average user requires. Even the most basic computer can be used for word processing, spreadsheets, using the Internet, or viewing photos.
 
• Unless you have a regular need for high-end applications, most desktop and laptop computers are overkill. Further, if you have fast internet speed you can often survive on an older computer with less “spec.”
 
2. Convenience: If you’re purchasing a used computer from a local computer business, it’s much easier to get repairs done. Try taking a new computer back to Wal-Mart for repairs. You’ll likely have to box up your computer and head for the post office. How long can you afford to wait? And yes, new computers sometimes have problems. In buying a used PC from a local shop hopefully you’ll be starting a relationship with a repair person there, also.
 
• A used (or new) computer is much easier to have serviced when purchased from a local provider rather than over the internet.
 
3. You won’t pay for things you don’t need. The primary difference between a current computer model and one that’s 3-years old is a faster processing speed, more ram and better graphics. These improvements aren’t necessary for 75+% of computer users. Why pay for more than you need? Also, many used computers already have expensive office and antivirus software and that is another expense you will not incur.
 
4. Windows 7 unavailable. Many users don’t like Windows 8. If you walk into Best Buy, Office Depot, Staples, etc. the only machines available have Windows 8. If you buy a used computer you can find one with Windows 7.
 
The disadvantages of a used computer:
 
1. Warranty: New computers include a warranty. If you’re purchasing a used computer from an individual or shop, they likely won’t include a warranty; however, purchasing a used computer from a computer business might include a warranty. Remember to ask!
 
2. The latest technology: If you need access to cutting-edge technology a new computer might be a better option. Consider what you truly need before making a decision. If you’re not sure what you need, ask someone with the necessary knowledge.
 
3. Lifespan: A re-furbished computer can potentially last as long as a new computer, but the used computer might naturally be out of date before a new computer. Again, assess your personal requirements and risk tolerance and the cost benefits of both.
 
4. The seller might be selling you a machine that has had a motherboard repair or might have been compromised in some other fashion. Similar to a used car the computer might have a past the seller might not know or be forthcoming about.
 

When using a search engine, there are several types of results that are returned. These results have different purposes. Knowing the difference can help your web browsing and your business. (You can click the images below to enlarge).
 
Paid Results: With most search engines, the first few results are usually paid results. This means that the companies or web pages listed actually paid the search engine for that positioning. Typically, these companies agree to pay a set amount every time someone clicks on the link. This is the largest portion of Google’s income, paid search results.
 
These paid results can also be seen on the margins of web pages and search results. Look at the photo to the left: The paid search results are circled in red.
 
Organic Results:
 
The organic search results can be seen circled in blue.
 
The various search engines have proprietary algorithms to rank web pages. The main purpose is to give the search engine user the most relevant possible results to their inquiry. There are hundreds of ranking factors search engines consider when deciding which result to populate in organic search results. These ranking decisions are controlled by an algorithm — which is a step-by-step procedure for performing calculations often controlled by software.
 
While the algorithm used to control search engine rank is unreleased here are some “suspected” ranking factors:
 
• Keywords: Google, Yahoo, Bing, and others, check to see if the right words appear on the web page for the primary topic. For example, a page about football would be expected to have certain words associated with it. The words quarterback, score, field, weather, players, etc., are all words associated with the topic of football.
 
• Links: Links to and from the website are also examined. The quality of the links is highly relevant. For example, a link from Harvard University likely carries more weight than a link from an unknown community college. In our football example, a link from another football website is probably a more important link than one from a car dealership, for example. This a voting system of sorts and fundamental to the original development of a successful search engine (Google – Founded September 4, 1998).
 
• Media: It’s generally accepted that pictures, video, and audio files increase the ranking of a web page. People tend to prefer a multimedia experience vs. one with only text. Also, it’s recommended to name photos since search engines have a hard time deciphering images vs. text.
 
• Age of the website. Older websites often tend to get more ranking credit than those there were recently created; however, this is not always true. A new site that is highly informative and popular can often outrank an older one with less activity and stale content.
 
• On page Engineering. Factors on the landing page such as readability, page load time, geo-locational information, etc. contribute to how high in search results pages appear.
 
Local Results: If you’re searching for the term “plumber”, you’re likely to get several results for plumbers in your area. Google knows that if you’re searching for the word plumber, it’s likely you’re looking for one that’s nearby. These local results typically include the company name, address, and phone number in a format that is unique when compared to other types of results.
 
See the green-circled area to the left.
 
Those are the three main types of search results. Paid search results are great, if you need or desire fast results. A bidding process determines the cost of paid search results. More valuable keywords will cost more.
 
Organic search results are free and can be even more valuable than paid search results. It means you have a great, relevant, and valuable web page. Getting to the top of the organic rankings can be challenging though. In many cases, expert assistance is required.
 
You’re more likely to appear in your local listings if you manually complete the listings form and fill it out completely to 100%. The search engines will eventually find your website and construct a listing for you. However, a listing that has been claimed by the business owner and filled out to 100% completion usually shows up more often in search results. The option to include photos, and in some cases even video, can improve the odds of appearing in the local listings. For more information on SEO please visit our website here.
