Choosing the Right Motherboard for you


The motherboard is the heart of any computer. It is that big flat board inside the computer that everything is connected to. It performs the role directing information and connecting components. A motherboard is often overlooked when choosing components. This is a scary thought as the motherboard determines system performance as much as every other component.

Choosing the right motherboard does not have to be a problem, even though there is a lot to consider. We will start off with the larger parts and move onto the things that are less essential.

Firstly is the socket type. The socket is where the processor (CPU) connects to the motherboard. There is no compatiblility between sockets, so it has to be the right one. The socket connection needs to match the connection of the processor you have or the one you intend to buy for the computer.
Most older Intel Pentium 4s utilize socket 478. Newer ones use socket 775. AMD chips utilised socket A for a long time, but now the AMD Athlon 64 series and Semprons use socket 939. Just check with someone as to what yours or your intended one will have.

Your choice of chip will have a lot to do with your needs, but choosing one with an up to date socket type will ensure slightly longer motherboard life as you can upgrade the chip for a while.

DDR is the RAM of choice for most systems, but some newer systems, which includes all Pentiums with socket 775 use DDR2. These two kinds are not interchangable and have a different number of pins. Both DDR and DDR2 come in different speed ratings measured in MHz. DDR has a usual 400MHz denoted as DDR400 or PC3200, while DDR2 can go a little higher and comes in slightly faster speeds. Just make it match what the board needs.

A motherboard must be chosen carefully, to both match all the other components and fit in the case you choose. A little bit of research before you buy will save a lot of hassle later on.

Anti-Virus Software Fighting Back Against Computer Infections


Many computer users adopt the ‘it will never happen to me’ policy, but there are a number of computer viruses out there just waiting to infect and destroy the information contained on their hard-drive. This is why companies invented anti-virus software, which is a program that automatically helps to detect the presence of viruses on a computer or in a file before it is opened.

Anyone who spends a considerable amount of time surfing the internet, visiting unfamiliar websites or downloading photographs is at a higher risk for computer viruses than those who do not. Computer viruses are typically attached to word processing documents, computer programs and images which, if downloaded, may instantly affect the computer’s performance.

If a computer virus infects a computer, the owner may immediately lose everything in their computer and may be forced to use the factory restore disk. This CD, which is accompanied by most new computers, will restore the computer to it’s original factory settings.

Computer Slow? Optimize It With The Right Tools


Why does it seem like every time you get a new computer it operates at lightning fast speeds for only a few months before becoming slow and laborious over its tasks? Is this just something that we have to live with or can we do something to keep our computers running at optimum speeds?

The truth is that computers do not get slower as they age, a slow computer is a sign that something is literally holding your PC back and affecting its performance. And the good news is that you can do something about it.

There are many things that can affect your computer’s performance, from low memory to a fragmented hard drive and everything in between. The things that can affect your computer’s performance are usually of your own doing. You see, each time we download a program or delete a program, we affect the way our computer operates. This change in operation can leave holes in our PCs operating procedures or may even leave behind programs that can affect our computer’s performance.

Computer Peripherals


When purchasing a computer you must consider not only the quality of the internal components, but also the external ones that make the entire multimedia experience possible.

Computer peripherals, from keyboards to web cams, are an important part of our activities whilst on the computer, if not the most important one, depending on our needs and habits. When you are faced with the situation in which you have to choose peripherals, consider a few things before making your move.

Computer lessons for beginners : how to use a computer mouse


Learn how to hold the computer mouse:
Hold the sides of the mouse with your thumb on one side and ring finger or pinkie, which ever feels more comfortable to you, on the other side. Your index finger goes on the left button and your middle finger on the right button. (Some computer mice only have one button, some have several, some have a wheel which you can use your middle finger to depress the wheel then turn it up or down to scroll pages very quickly or slow depending on how quickly you turn the wheel. Personally I love the wheel and would not have a mouse without it!) When you are told to ‘click’ use the button under your index finger, or the left button.

Learn how to move the computer mouse:
Slowly slide the mouse around on the mouse pad. See what happens to the arrow on the screen as you slide it around.

Do you need a mouse pad:
You should have a mouse pad under your mouse, (although the new optic mice do not require one). You will have an array of choices when purchasing a mouse pad; find the one that is comfortable for you. Rest your hand on the mouse pad or desk and move it slowly, there is no need to lift the mouse off the mouse pad unless you run out of room, then you just lift it up and reposition where needed. You don’t need to move the mouse to the left or right, simply slide it left or right with the buttons still facing away from you.

What does clicking do:
Clicking sends a command to the computer. To click, gently press and release the left computer mouse button. Be careful not to move the mouse while you are clicking, if you accidentally do simply slide the mouse back to where you want to click and try again. Try to keep you hand relaxed on the mouse as you press and release without lifting your finger completely off the button.

You are Done – Great job! That is all you need to know to start using your computer and that mouse. Keep working on it and before you know it, it will feel like second nature to you and you will not even have to think about what you are doing.

Buying a Refurbished Laptop Computer


When considering buying a used or even a new laptop, the first thing you need to do is to determine your computing needs.

* word processing
* e-mail
* browsing web pages
* moving the laptop from home to work (weight)
* gaming
* on-line shopping
* a database application
* personal finance
* is battery power important

Check out the Minimum Systems Requirements needed to do all of the your applications. They will not come with the laptop, as refurbished laptops often only include the Operating System (OS). If they don’t include an installed OS, then be prepared to install it yourself. This is not for those that don’t know what they are doing, so research what is involved before buying one without an OS.

Once you understand what you really need, you need to determine your budget.

Most old laptops do not have working batteries. If you need a battery, shop around to figure out how much they cost. You should know that on older laptops, batteries don’t last more than an hour or two, so purchasing a new battery for the purpose of longer battery life may not be worth the expense. And by all means, stick with a name brand… IBM, Dell, Toshiba, Compaq-HP.

If you are new to computers and you want to browse the World Wide Web, you will need to obtain the services of an ISP (Internet Service Provider). There are basically two types of Internet access options: broadband (cable modem, DSL, satellite) and lowband (dial-up). Broadband is the preferred type since download speeds can range from 128kbs to 6000kbs. The faster the better, of course. But, if your budget is tight, dial-up works just fine for typical browsing and e-mail usage.

Your choice of ISP’s will be dependent upon two things: budget and location. If the budget allows and you don’t mind paying upwards of $35-50+ per month, you can purchase a broadband connection. However, even if money were no object, your physical location will determine what types of services are available to you. Broadband is not available everywhere (with the exception of satellite). If you have a telephone line, you can always choose dial-up. AOL’s bread and butter is dial-up users. Do your research to determine what is available in your area and compare costs.

And for you gamers out there, you definitely need a reliable broadband connection. Gaming over a lowband connection can be a frustrating experience and sometimes even impossible. You will need to check out the minimum systems requirement for the games you are interested in using to make sure the CPU speed and the RAM and graphic chip requirements will support the games you wish to play.

Once you have figured out your budget and your needs and the requirements of your laptop it is time to search for the laptop of your desires.

Some people choose to search at www.ebay.com. If you do be sure to check out the seller to be sure you will have a smooth transaction.

Many people don’t want the hassle of bidding, so use your favorite search engine: Google or Yahoo or MSN for the terms “used laptops” or “refurbished laptop”.

An important thing to keep in mind is how will the vendor treat you should there be a problem. If you don’t like their attitude or they don’t pick up the phone shop elsewhere. Price is important, but if you have a problem and spent the least amount of money possible the vendor may not have any resources available to help you after you have purchased and spent your money.

If all the above seems like too much of a hassle, then buy a new computer. It will cost around $700 + but will come with a new battery and a one year warranty, although some new ones seem to have only 90 day warranties. It will also have the latest Windows XP system and an 800 number to call the vendor, should their be a problem. I’d call the 800# first before buying to get an idea what kind of support they will provide.
