Ensure that the computer parts are compatible with one another! Also, if this is your first time building a computer or barebone kit, it may be wise to find someone who can guide you through the process so as to prevent damaging y our hardware components. Never force the components into their respective slots! If they don’t fit relatively easily, then something is wrong, double check to ensure the functionality and integrity of the integrating hardware component mechanisms.

How To Build A Barebone Computer – Step 1
Plan your budget for the computer kit you want to buy.

The very first variable you want to consider when building a computer is your budget. How much are you willing to spend? Basically if you build your computer you can save hundreds of dollars on parts. But how much do you have in mind? Also consider what additional hardware components you may need in addition to just a PC computer, such as printers, mice, keyboards, and monitors.

How To Build A Barebone Computer – Step 2
Make a list of all of the essential components that you will require. Typically the essential computer hardware components you need when you build a computer are CPU (Central Processing Unit), RAM (Random Access Memory), hard drive, motherboard, powersupply, and computer case. Additionally, consider if you want to make utilization of the videocard on your motherboard, or if you want to get a separate videocard. If you intend on using video intensive applications such as developing programs, or games, then it would be best to get a separate videocard to handle the computations.

How To Build A Barebone Computer – Step 3
Once you have purchased and obtained all of the necessary hardware components to build a computer, you want to plan and think how they will all connect to one another and verify you’re ready to begin. Ensure that you have an anti static matt to work on and that the humidity in the room isn’t too high. An anti static wristband can also be helpful, and the manuals that came with your motherboard and computer case can be helpful and often provide schematics explaining how to connect the components to the board and case.

How To Build A Barebone Computer – Step 4
Get a clean working environment that’s well lit and contains a flat surface. A kitchen table or a work bench often work the best. Remember you want to avoid static electricity at all times when building a computer, so try to avoid cotton clothing and wear rubber shoes!

How To Build A Barebone Computer – Step 5
Ensure that you have all the tools necessary to build a computer! I would suggest a flathead screwdriver, a phillips head screwdriver, and maybe a torx screwdriver. Please refer and analyze the hardware that is attached to your computer case, hard drive, and DVD roms to ensure you have the adequate tools to build a computer. Also, it’s wise to have a flashlight, and a pair of tweezers to attach the jumpers for the front panel connectors on your hard drive if your hands aren’t that nimble!

How To Build A Barebone Computer – Step 6
Now you can begin actually configuring your components. First, place the ram into the motherboard. If you’ve done your research accordingly, the ram should fit without problem. If there are color coded ram slots, ensure to abide by the color coordination! Some have a pattern of blue, black, blue, black, in this instance, if you install 2 ram cards, make sure to color coordinate! Install 2 blue, and 2 black. You know it’s installed correctly if it snaps in snugly. After your ram is seated, install the processor, and heatsink fan. Ensure to place thermal compound between the CPU and the heat sink fan in order to ensure an equal distribution of heat!

With the ram, cpu, and heatsink installed the videocard should be installed, if you decided to obtain one. Ensure that it fits snug in its correct slot, and most PCI Express slots have a pin that “locks” so you know it’s correctly placed.

Once the CPU, videocard and RAM are secure, the hard drive, and DVD rom should be plugged in. Next you need to screw the motherboard into the computer case, and ensure that you use risers! It’s very important that you don’t screw the motherboard directly to the case, this will cause a short out and a serious malfunction to your board, so don’t forget the risers!

How To Build A Barebone Computer – Step 7
With the motherboard secured in the computer case, you should make sure that the back panels are aligned properly with the back of the case. Your monitor, mice, keyboards, and other external components will rely upon a clear access point for the back of the computer case. With the back panel established, it’s time to connect the front panel case connectors to the motherboard. Doing this can be tricky as they are the smallest components in building a computer, so refer to the motherboard manual to learn the correct settings, and also you might want to use tweezers if your hands don’t have much dexterity.

How To Build A Barebone Computer – Step 8
With your hard drive, cpu, ram, videocard and motherboard installed, it’s time to install the power supply! Ensure that the power supply fits snug, and then plug the power connector into the motherboard. Many modern motherboards require two separate power connections, so observe the motherboard manual to ensure both of them are snug. Once the powersupply is seated properly and plugged in, it’s time to close the case, plug in your monitor, mice, keyboard, and power the machine up.

How To Build A Barebone Computer – Step 9
One of the most important steps in how to build a computer is setting up the operating system. Once you have installed all of the components you should make sure you have a operating system DVD. Windows 7 is one of the best Microsoft operating systems and is of recommendation. You may have to verify that you can boot from your DVD rom drive by going in your BIOS, if not already established, boot from your DVD rom first, and follow the on screen instructions to install Windows Vista.

How To Build A Barebone – Congratulations! Hopefully this guide offered a resolution that will save you hundreds of dollars. Remember, building your computer from scratch or from a barebone computer system can save you hundreds of dollars, offers you an element of customization impossible to obtain from most retailers, and most importantly educates you about system hardware components and computer science. If you ever require additional information, the best resource is the documentation that came with your motherboard, cpu, and other components, but please feel free to make wise utilization of this documentation! Happy computing.

The first personal computers were made available in the 1970s and were so simplistic that they were sold in kits, which could easily be put together by the consumer. The famous Apple-1 was the first personal computer to come with a fully assembled circuit board. However, one still had to provide a case, power supply, keyboard, and display for their Apple-1. When comparing today’s personal computers to the first models, one can see how advanced computer technology has become over a short period of time. For instance, gigabytes, MP3’s, AVI’s, USB’s, UPS’s and dual cores are terms that never existed in the 1970s, but are all common terms today when discussing computer technology. When today’s computers become damaged, a computer repair firm that specializes in PC repair and IT consulting in Cleveland, Ohio can help one understand what went wrong with their complex machine, how it will be fixed and maintenance tips.

Computer manufacturers do not work with consumers on a personal level when it comes to computer repair. When one sends their damaged computer to its manufacturer, it requires a mailing fee. Then the usual repair time is a couple of weeks to a month. After the repair is made, the consumer then has to wait at least a week before they receive their computer. The computer manufacturer may only disclose what was repaired in the consumer’s copy of the work order or receipt, but will not tell the consumer how the computer failed or how it was repaired. If the consumer calls the manufacturer with questions, they have to go through a hierarchy of employees starting from the bottom.

One blogger on Askville.Amazon.com, said when he contacted HP to troubleshoot one of its computers it took them two hours and then another hour to authorize the return. The blogger said it took two weeks before HP sent the repaired computer back to him. He also said when he contacted Dell to troubleshoot one of its latest computer models, he was put on hold excessively before he was able to authorize the return. He said it took Dell three weeks to send him back the repaired computer.

A computer repair company that specializes in PC repair and IT consulting in Cleveland, Ohio can offer certified computer technicians who will work with the PC owner one on one at their home or office. This not only allows quicker repairs, but also gives the PC owner the opportunity to establish rapport with the computer repair firm, allowing an opportunity for discounts and other deals on services. A PC owner has the chance to ask questions about how their computer failed to understand how to avoid it from happening again. For example, a computer technician from a computer repair company that specializes in PC repair in Cleveland, Ohio can inform the PC owner what Web sites to avoid to prevent the downloading of adware, spyware and viruses to keep their computer performance at optimal level after the repair is made. A computer technician from this type of firm can inform a PC owner to use surge protectors to prevent electrical damage after replacement of the damaged part.

Since computers are complex machines a lot more can go wrong with them other than virus infection and electrical damage. A computer repair company specializing in PC repair and IT consulting in Cleveland, Ohio can get to know the PC owner and their computer habits, since its computer technicians are able to work with the consumer on a personal level. This means the firm will know what maintenance tips to tell the consumer to keep their computer running for a long time and to save them money. Here are a couple of examples:

Never turn the computer off with the power switch until Windows has shut down

This will prevent permanent hard drive defects and Window problems from occurring. Use the Ctrl + Alt + Delete keys to restart the computer if it crashes.

Use an USP, uninterruptible power supply for the computer

This prevents the computer from crashing during power outages and protects it from low and high voltage shortages (some say a USP is more superior than a surge protector)

Back up important data on at least two separate physical drives

-Hard drive failure is a common occurrence

Run Scandisk and Defragment at least once a month

This can prevent crashes

Never unplug peripherals from the computer when it is powered up

This can short out the motherboard

Keep at least 600 MBs of C: drive free

This can keep the computer from running slow. Windows XP and Vista requires 400-600 MBs.

Use a firewall program

A firewall program prevents hackers from gaining access to the computer system

Keep every software disk

Disks can contain important drivers that need to be reloaded

Computers are complex machines that require certified experts to fix them the right way. When a computer needs repair, a computer repair firm that specializes in PC repair and IT consulting in Cleveland, Ohio can offer more than a computer manufacturer. The firm can offer the right expertise at one’s home or office to make the repair faster, offer better deals, and gives maintenance tips to save PC owners money.

Chad King is CEO and President of KingPin Computers, a certified computer repair company based in Cleveland Ohio that specializes in PC and laptop repair including spyware and malware removal, software and hardware installation, data backup and recovery for residential and commercial customers throughout Northeast Ohio.

1. Introduction to Cloud Computing

Cloud computing refers to both the applications delivered as services over the Internet and the hardware and systems software in the data centers that provide those services. The data center hardware and software is what we will call a Cloud. Cloud computing is relatively new concept and it has become popular recently. Cloud leverages virtualization technology and in the essence of Cloud computing there is a logical separation between different nodes, each node appears as a different physical machine to the user. Unlike grid computing, it makes several distributed computers connected together to form a big logical computer which can handle large amount of data and computation. In case of Cloud computing the virtualization technology makes it possible to have each node appear as separate physical machine allowing user to load custom software and operating system on each node and configure custom rules for each node.

The idea of Cloud computing is evolved from parallel processing, distributed computing and grid computing. There is a bit similarity between them but they work differently. Although Cloud computing is an emerging field of computer science, the idea has been around for a few years. It’s called Cloud computing because the data and applications exist on a “cloud” of Web servers. To simplify the concept, Cloud computing can be defined as simply the sharing and use of applications and resources of a network environment to get work done without concern about ownership and management of the network’s resources and applications. According to Scale, with Cloud computing, computer resources for getting work done and their data are no longer stored on one’s personal computer, but are hosted elsewhere to be made accessible in any location and at any time.

2. Related Technology Comparison

2.1. Grid computing A form of distributed computing and parallel computing, whereby a ‘super and virtual computer’ is composed of a cluster of networked, loosely coupled computers acting in concert to perform very large tasks

2.2. Utility computing The packaging of computing resources, such as computation and storage, as a metered service similar to a traditional public utility, such as electricity.

2.3. Autonomic computing

Computer systems capable of self management.

3. General mechanism

Cloud computing using information technology as a services over the network. The concept generally encompasses of Infrastructure as a service (IaaS), Platform as a service (PaaS) Hardware as a Service (HaaS) and Software as a service (SaaS). It can be the ability to rent a server or servers and run a geophysical modeling application available anywhere. It can be the ability to (S Rupley, 2009) rent a virtual server, load software on it, turn it on and off at will, or clone it to meet a sudden workload demand. It can be storing and securing large amounts of data that is accessible only by authorized applications and users. It can be supported by a cloud provider that sets up a platform with the ability to scale automatically in response to changing workloads. It can be using a storage cloud to hold application, business, and personal data. And it can be the ability to use a handful of Web services to integrate photos, maps, and GPS information to create a front page in customer Web browsers.

In a cloud computing system, there is a significant workload shift. Local computers no longer have to run applications. The network of computers that make up the cloud handles them instead. In this situation the demand of hardware and software on the user’s side is decreased. Let the cloud take care of it. The only thing that local computers should aware is the interface software that will run the application. Today’s, a Web Browser such as Mozilla Firefox and Internet Explorer 8 is widely use as an interface software in cloud computing system.

The truth is, internet users already used some form of cloud computing. If they have an email account with a Webbased email service like Hotmail, Yahoo! Mail or Gmail, then they had some experience with cloud computing. Instead of running an email program on a local computer, user will log in to a Web email account remotely. The software and storage for the account does not exist in the local computer it is on the service’s computer cloud.

4. Key characteristic of Cloud Computing

Currently, there is no standard definition or specification for Cloud Computing. It may take some time to define the key characteristics of Cloud Computing based on practices in the field.Based on practices in the areas of service provisioning and solution design, the following two key enabling technologies could play a vital role in this revolutionary phase of cloud computing:

4.1. Virtualization technology

Virtualization technology works to handle on how the image of the operating system, middleware, and application procreated and allocated to a physical machine or part of the server stack away. The virtualization technology can also help reuse licenses of operating systems, middleware, or software applications, once a subscriber releases their service from the Cloud Computing platform.

4.2. Service Oriented Architecture (SOA).

A service oriented architecture is essentially a collection of services. These services communicate with each other. The communication can involve either simple data passing or it could involve two or more services coordinating some activity. Some means of connecting services to each other is needed. The evolution of a system or software architecture is now moving towards services oriented, unlike several decades ago most of the application is stand alone and purposely for single use. Recently, the gigantic growth of the internet user and internet technology availability the use of software now can be rented. Giant company such as Google, Microsoft, Sun or even Amazon have this capability provide software services instead of selling the software directly to user. The SOA is software or system architecture that addressing componentization, reusability, extensibility, and flexibility. These entire characteristic is a fundamentals need for company that are looking for reducing cost and opt to rent instead of purchase.

Cloud Computing full document

Today, computers can now be found in nearly all homes and businesses. We rely on them and technology to assist in many of out daily activities such as banking, shopping, managing a business, communication, and much more. However, computer technology is constantly changing making it very difficult for consumers and businesses to keep their systems current as it can be very expensive to continually buy new computers. Today, many people are turning to used computers as an affordable alternative to buying brand new computers. Used computers are previous owned computers that have been refurbished for resale. Companies will acquire used computers from owners who trade in their computer for another upgraded one. There are many reasons why buying a used computer is more beneficial than buying a brand new unit.

The following outlines the reasons why it is beneficial to buy a used unit:

Excellent price: The price of a used one is far less than a new one, often from #100 to a couple of hundred dollars. Prices will normally depend the age of the computer. Generally, the older the computer is, the cheaper the price.

Quality Tested: When you buy a used unit from a quality used retailer, you are assured that the piece has been tested to make sure it is operating at peak performance. The technicians will test each one, identify any problems, and fix the problems. New units are normally just ‘spot’ tested.

A Used Computer Warranty: When you purchase a used piece, the retailer will normally provide a quality warranty. As well, in many cases, the manufacturer’s warranty will still be valid, depending on the age of the unit. You can often purchase an extended warranty at a reasonable price.

Option of Return: Quality used retailers will offer a set period where purchasers of used computers can return the used computer if they are unhappy with it after they have tried it at home. However, you will not be able to return it if it suffers damage such as spilling liquid on it while in your care.

Less Expensive to Upgrade: Today, there is always new computer technology coming out on the market. After a few months of ownership, a new computer can often become outdated. It is often cheaper just to upgrade a used computer when new technology emerges. Constantly replacing computers with new computers can be really expensive.

Brand Name Used Computers: If you are a fan of Dell, HP, or Apple, you will be able to find these quality computer brands for sale as used computers. You will get a quality brand name used computer at a much cheaper price.

Because our lives are now so dependent on computer technology, having a quality computer has become a necessity. Because of constantly changing computer technology, it makes sense to consider buying a used computer. Not only is a used computer an affordable solution for an individual or business, but a used computer allows for an inexpensive way to acquire and maintain the latest technology without having to spend a small fortune.

At low prices and with such convenient access, purchasing used computers Toronto is an economically viable option for those seeking quality technology. Another recommended alternative is laptop rental and computer recycling Toronto, which allows users to conserve money and test the platform first-hand.

Can antivirus software save my computer or laptop from a costly repair?

Antivirus software aims to do just what it says on the tin; by protecting your computer from all the malicious malware out there lurking on the web.

Computer viruses come in many forms, and these malicious programs don’t have to been downloaded and manually run in the way you may have thought.

Computer Repair Myth. We can fall victim to a computer virus sent by other computer users we know and trust. By opening an email attachment that contain a hidden virus program, we not only infect our own computer or laptop, but once installed, this kind of virus will attempt to send itself to the other computers in your email address book.

This type email computer virus attack is prolific as infected computers will continue to send infected files until the computer is repaired and the virus removed. If we scan our email attachment before we download them to our computers and laptops we will avoid this type of computer virus infection.

The Trojans
As the name suggests, these programs masquerade as harmless files such as media player plugins, but in reality they can be some of the most damaging computer virus infections. Once we have downloaded and run a Trojan file the virus will begin collecting information about our surfing habits and our usernames and passwords. I think almost everyone can see where this computer virus problem will lead to.

The Worms
Worms are another form of virus; these can infect a pc without you having to do anything at all, plugging in a USB memory stick, connecting to the internet using a CD ROM etc… can be all that is needed to allow your PC to become infected. These can effect PC performance, prevent applications from working, and occasionally prevent your PC from booting altogether.

Often we find customers come to us with what on the face of it looks like a computer or laptop hardware fault. But once we examine the machine we find the machine is infected with a virus. Usually many viruses.

What we have covered here are just a few of the ever increasing malicious programs that continue to infect our computers. As I’m sure we have mentioned before; prevention is better than cure. One good antivirus software should keep your computer safe and allow you to avoid the computer repair shop.

When is a professional computer repair service needed?

Once your computer or laptop is infected with a computer virus you should seek professional help from the guys at your local computer and laptop repair shop.

In our experience finding one virus is just the tip of your computer problems. The removal of computer viruses is not that straight forward as some would lead us to believe.

1. Not all antivirus software scan for the same threats.
2. In addition some viruses are designed to avoid certain removal methods used by the large antivirus software programs.

To completely check and remove every virus from your computer, your machine will need to be scanned by a range of virus removal techniques and software.

Simply scanning a laptop or computer with one antivirus program and getting a clean bill of health is a sure fire way of incurring a more expensive data recovery computer repair in the future.

My computer has a virus, what can I do?

1. Disconnect the computer or laptop from the internet.

2. If the laptop is part of a computer network, disconnect this to.

3. Don’t install any antivirus software. I know it’s tempting, but it’s pointless because you can’t be sure if the scan results are true or if they have been manipulated by the virus on the computer.

4. Call your local computer repair shop. Tell them that you laptop or computer has a virus and ask them for a quote. Some of the better computer repair shops will even come and collect your laptop free of charge.

5. Once the virus has been removed and the computer repair guys have returned your machine; now install the antivirus software onto your laptop. If you try to keep it up to date, you should have may happy years surfing and you will avoid the guys at the computer repair shop.
