Computers are made of different components or parts, collectively known as PC hardware. Some of the main hardware PC units include CPU, mouse, display screen monitor, hard disk, keyboard, CD drive, etc. You can buy a computer from a branded company or purchase an assembled model through a professional computer software person. Many a times, when some parts of a computer get corrupted, you can also buy separate components from any online or offline computer dealers.

Likewise computer hardware parts also do include novel items such as scanners, sound cards, internet modems and even digital cameras. But, every computer has individual properties like RAM memory, CPU model details, etc which may vary from other computers.

Let us study about some of the most important computer hardware parts:

* CPU- This part is the brain of the computer. It is known as Central Processing Unit and works as a processor. The most popular processors are manufactured by Intel popular as the Pentium Chip model. Intel processors are widely used all over the world by most of the computer manufacturing companies.

* Mouse- This hardware is essential for desktop models as navigational object, to click on varied options, selecting different objects and accessing necessary information on the computer screen. There are two main buttons in the mouse, to be used to access info. Nowadays, you can find interesting types of mouse in the market such as laser mouse or ball mouse. But, they all serve the same purpose to help access computerised info from the CPU.

* Hard Disk- This is a device that helps in storing data. The all-round performance of any computer actually depends on the speed of its hard disk. Higher rotational speed of the hard disk enables fast and high speed performance by that particular computer.

* RAM- It is also known as Random Access Memory, which aids in storing of temporary information in the CPU. When you switch off the computer, such temporary info files are erased. The optimum performance of the computer also depends on the size of its RAM.

* Keyboard- This is one of the most important part in computer hardware. Keyboard helps users to enter specific commands by punching of alphabets, numbers or signs. There are other function keys like Control, Alter, delete, F keys, Page up, Page down, etc in the keyboard. There are a total of 101 keys in any standard keyboard, and designed in such a way so as to make typing faster and easier.

Other additional computer hardware includes scanner, joystick, external drive, printer and servers. Buying individual computer hardware parts can be a tedious task as there are variety of selection models, styles and designs to choose from. It is best to gather some basic first hand info about the specific computer hardware part that you intend to buy.

You can choose to buy from online computer hardware retail shops and other hardware dealers. Online directories can help you sort a list of potential manufacturers or retailers who are genuine and trustworthy.

No doubt computer has made our lives easier manifold. Though the online activities are endless, computer problems are always bound to be there if you have a system at home. Some may be easy to solve while other types of problems may not be a bit difficult to attend. The annoying thing is sometimes you may not know the exact reason for the problem itself.

Computer problems can be classified as two types:
Hardware problems
Software problems

The hardware problems are related to the physical components of the systems while the software issues are related to the ms windows, driver errors, modem issues etc. Given below are some of the common computer problems and their possible solutions.

Computer Problems due to Power Outage
The intermittent power cuts and voltage fluctuations may cause problems to the computers and disrupt your work. If there isnt adequate power back up for your system and if it gets switched off due to sudden power outage, then it may cause temporary or permanent loss of data, hardware issues etc. The best way to combat computer problems due to frequent power cuts is installing UPS (Unlimited power supply) for your PC. Even if the power goes off, the UPS will give you about 15-20 minutes of power backup. During this time, you can save the programs in which you had been working on and comfortably shut down your system without any hassle.

Drop in system speed
Most of you would have faced the problem of your system being dead slow in responding to commands. Sometimes, the system might take several minutes to execute an operation for what it should have taken only a few seconds. Slow system performance can be one of the most annoying computer problems. In such a scenario, be sure to check whether there is enough space in the hardware and also if the RAM memory is more or not. If you have stored any necessary files or folders or large videos and forgot to delete them long back, then you may get rid of them right away without wasting any more time. Perform disc defragmentation and disc cleanup to create more system space. If necessary, upgrade your RAM and hard drive for better system speed. Do the above steps and be surprised to find at least 40-50% increase in the system speed.

Speaker issues
Dejected that your speaker didnt produce any sound when your favorite song is being played on? Dont worry; this can be sorted out easily. Check at the back of your CPU whether all the wires from the speaker are plugged properly in the appropriate places or not. It is very common that the wires may be in loose contact. See the color of the wires and plug them into the right holes and make sure there isnt any loose contact. Once everything is perfectly done, then start enjoying your favorite music as you wish.
Computer producing Strange Noise
Note that the noise problems are completely associated with the hardware parts of your system. In such a case, switch off the system and unplug the power supply. Remove the CPU box and clean it and allow it to cool down for some time. Now reassemble the parts and make sure there isnt any lose contact. Your system is ready to go noiseless!

Computer Reboots Itself frequently
If your system reboots itself over and over again, then check whether there is any fault in the hardware connections or not. Sometimes, low voltage and power outage may hit the CPU and cause the system to reboot frequently. An ineffective cooling fan at the back of your CPU could also cause such a problem. Clean the fan whenever it is covered with dirt. Place your system in a cool area in your home, preferably near the windows as the system needs cool air to prevent from getting heated up.

When wanting to purchase a brand-new pc you could not in fact require a drive. Take into consideration a pc that merely possesses a CD/DVD mix drive. Flash drives, external hard disk drives and cloud storage space available online make it less complicated for you to save vital documents without jumbling your pc’s hard disk drive. This can save you money and lower the weight of your laptop computer.

Examine to figure out if you could readjust memory and RAM on the laptop computer. You could not have to now, however you could intend to in the future. It’ll be much cheaper to upgrade your aged machine than to acquire a new one. Keep these things in thoughts just before you acquire a brand-new laptop.

Take into consideration the dimension of your display. When it pertains to laptops, you can save a bunch of money by going with a smaller screen. While you might link an external screen when you travel with it, it is very important to consider just what you do and exactly how large you need the show in order to do it appropriately. For instance, if you deal with graphics utilizing a tiny display may not be ideal. You have to ensure it’s big sufficient for your needs.

Do the correct quantity of research just before you acquire a laptop. Do not see an offer and jump at it. It might not have the appropriate specs for you, and it could not be at all what you wished. Also if you acquire thrilled for a price, don’t get up until you have inspected it out.

Do not overspend on your laptop computer purchase. There was a time when you needed to spend $1000 or more to obtain an excellent laptop, but those days are long gone. Today, you could find terrific alternatives for $700 or less, and it is worth shopping around to get these kind of prices.

You need to consistently think about size when thinking about what laptop to buy. They normally come in between 13″ to 17″ when they are diagonally gauged. If you’re trying to get a laptop computer that functions as your desktop computer, then acquiring one with a monitor that’s 17 inches will be your best bet. If you take yours everywhere, you may wish a 13″ one.

With netbooks, do not obtain confused. While some folks take into consideration a netbook to be a laptop computer that’s compact, that merely isn’t right. Netbooks allow easy Web use in addition to email, however they do not have the ability and power linked with a laptop computer. Don’t obtain a netbook if you want a laptop when all is claimed and done.

To keep your laptop computer secure while driving, pack it in its very own luggage; if you do not have a different laptop computer bag, then get a padded case for the laptop computer that you could place in an additional bag. Ensure that there is nothing else in that larger bag heavy enough to fracture the screen with the case.

For people which do a bunch of multitasking, after that RAM is a crucial feature on their laptops. The cheapest laptop computers will certainly have much less RAM compared to the more expensive models. For high-end applications, games, and multitasking, a computer with a huge quantity of RAM is visiting be a necessity, not an option.

Its 9:00 on a Sunday evening and the phone rings. It is my Dad telling me that his computer is running slow, giving unusual error messages, takes forever to start up or something along those lines. He needs it working tomorrow when the stock market opens.

Three years ago I gave my 80 year old Dad a rebuilt computer of mine so he could check his stock prices without calling his broker all day long. He can get on the internet, read the news, go to Yahoo finance and check stock prices and look at a few other pages that I have saved in his Favorites. That is pretty much it. If anything out of the ordinary happens, he calls me. Other than the time a cricket got into his computer, all that the computer has ever needed is to have a good electronic scrubbing.

I highly suggest that everyone stick to a regularly scheduled maintenance program for their computer. How frequently this needs to be done is dependent on how much you use the internet the source of all of the spyware, viruses, browser hijackers, cookies, temporary internet files and other malware that can affect your computers performance. I maintain my work computer weekly, but this may not be necessary if you do not spend forty plus hours a week on your computer. My second computer that is not used but a few hours a week is only maintained monthly at best.

Here is a list of the things that I do to keep my computers running at peek performance:

1.Always keep your antivirus program up to date and scheduled to run daily at a time when your computer is on, but not in use. I have been using the AVG free version for many years and highly recommend it.

2.Run the free Adaware from Lavasoft weekly. It is a spyware removal program, with paid upgrades available. Adaware removes spyware, dialers, Trojans, browser hijackers and much more. It is best to remove it all regularly since even the less harmful stuff slows your computer down and wastes space. The free version of Adaware will remove most spyware and does not take very long to run, so I run it first.

3.Run Spybot. Spybot is another free spyware removal program. It will often pick up a few more nasties that Adaware missed. This program takes a bit longer to run than Adaware but is worth it.

4.Clean out junk files (temporary internet files, cookies), remove invalid registry entries, another check for spyware, defragment your hard drive and RAM and optimize your startup menu. I use a program called System Mechanic by Iolo Technologies. I bought this program for around $25 not long after Windows XP was released in 2001. I still use this product regularly. It performs these tasks quickly and is very user friendly. This product is a must have and a bargain in my opinion. I am sure System Mechanic has made many advances in the last seven years, but my old version still works very nicely for me (until the custom computer shop I use quits selling computers loaded with XP!).

This may sound like a lot of work to do on a weekly basis, but is well worth it. I do this on Sunday evenings when I am usually lounging around the house watching TV. I set a program to run, check back in a while when it is done and then start the next one. This way, it is not that much of an inconvenience.

See ya. Gotta run over to Dads now to clean up his computer.

Once you have decided to give your kids a computer and an office for school work, what exactly the second step? The primary decision you need to make is what kind of computer to buy. Your choices are desktop, laptop, tablet.

Desktops have been traditionally what is thought of when one imagines a computer. The benefit of desktops is that you can have excellent hardware. Furthermore, the components in a desktop are usually easily accessible, so you can upgrade it later on, rather than purchasing another new computer. You could improve the video card, or add a hard drive. Desktops also usually contain six or more USB ports, whereas laptops only have half that many. The most powerful CPUs and GPUs must have large cooling fans, and these will only fit in a desktop. Desktops also can display to multiple monitors. The drawback of desktops is that they are not portable. They are designed to reside on your desk. A desktop is ideal if you need a fast computer for graphics design. Reliable desktop manufacturers are Alienware, CybertronPC, and Sony.

Laptops are smaller and easy to transport compared to traditional desktops. In the past they had been not as powerful as desktop models, but more recently, laptop computers are designed to be just about as able to be productivity machines as desktop computers, for most everything but the most power hungry applications. One of the downsides of laptops are that they have space limitations, and processors designated for them draw less power. What this means is that laptops can’t have the large fans that are essential to use the speediest CPU’s. A standard hardware configuration includes an Intel or AMD brand CPU in a laptop. Additionally, there are fewer USB ports. The components are precisely installed, and swapping components after you own the computer may not be possible. Some laptop computers give you the ability to upgrade the RAM. The primary reason to buy a laptop is that it is portable. If you take your work with you, then this is a good option. Excellent laptop brands are ASUS and Microsoft.

Tablets may appear to be laptops without keyboards, and in some cases, that is exactly what they are. With the widespread availability of touch screens, tablets are universal. Most businesses sell laptop and tablet combination computers. Alternatively, you can shop for a separate removable keyboard for quite a few tablets. Tablets are portable, and thin. Tablets aren’t usually considered as the initial choice for your office computer. The attitude is changing, however, because tablets have advanced in the last few years. As an example, you can download office applications. You can also give presentations. They are superb for a mobile lifestyle. Tablets use one of three major operating systems. For example, iOS. Good tablet manufacturers are Google and Lenovo.
