Because computers are run by operators,User Error is the most common cause of computer malfunction.When the user is at the computer,he or she may add or delete certain files.Or he/she may remove or exchange certain hardware features.

When we look at user error,we must remember that since we’re human,the user error may be easy to solve by simply asking the last user if he/she installed any software,re-configured any software or hardware settings,etc.

Free Registry Cleaner To Fix Windows Errors

In most cases I can tell you most computer’s will a few if not many corrupted files located inside the registry or in the hard drive. I believe that there’s nothing worst than having your Windows system slow down, have a blue screen or just plan old crash. Your Registry will soon give you another problem in which I believe is related to the entire operating system of Microsoft Corporation.

Your registry holds both your hardware and software application configurations for your computer. Since your registry holds such important information Windows is consistently grabbing the data it needs from the registry in order to run and keep your computer running.

Since your registry holds such important information Windows is consistently grabbing the data it needs from the registry in order to run and keep your computer running, and after your installation of any applications you may run the risk of corrupting you registry further.

No matter how much experience or effort you put into fixing your registry you might still have a few uncorrectable errors left. Based on my experiences, as time goes by you’re going to eventually install new programs and hardware into your computer, and you’ll also be uninstalling them so you run the risk carrying unwanted and invalid registry entries; this will prevent your computer from operating smoothly.

So now that you know the wretched thing that can happen here’s two way you could try to use to fix your registry errors.

– Save a copy of your registry and keep a backup copy somewhere on your computer.

– Use a popular registry cleaning software often. Please make a note that this is the best solution and keeping a backup copy of your registry is also another method to use along with this. By using registry cleaning programs you’ll be able to scan and repair any possible errors in your registry. Know this, you do not need to be technical when using this software because it’ll scan and fix your registry errors automatically.

Never used this type of software before? Don’t worry it runs on automatic and if you want you can play with the settings to scan specific parts of your registry entries like wrong DLL files, wrong start entries, missing fonts in your computer and much more.

There’s a massive range of different software brands for registry cleaners that you can find online. I’ve prepared a list of things to look out for when selecting the right software:

1. I’ll say you need a special feature that will give you backup and restore functions of your registry.
2. The ability to warn you when your registry is being modified in a major way.
3. The most valuable aspect of the software developer is customer service and technical support so make sure they have both
4. Find out if the software is easy to install and comes with help files.

Build Your Own Computer or Buy?

Build Your Own Computer or Buy?

Just look inside a computer case. At first glance, all those wires and components can look terrifyingly complex. And thinking about putting them all together by yourself may seem impossible.
Not to worry! Even though they are the products of advanced technology, the various pieces of a personal computer (PC) fit together with simple connections. If you can use a screwdriver and follow simple instructions, you can build your own PC.
Don’t be intimidated by the task of connecting the computer components together. Many of the internal connections are molded so that it is impossible to fit them together the wrong way. If you have ever assembled a child’s toy, you are more than capable of assembling a computer.
Advantages Of Building Your Own
You are probably asking yourself why anyone would bother to build a PC. After all, you can buy a cheap computer in almost any retail store.
If cost is your only consideration, you probably are better off buying one of those cheap machines. But if you have any special requirements for software or hardware, you’ll benefit from the total control over the type and quality of components you get from building your own PC.
You can save some money, too. Although you probably can’t match the price of the cheapest preassembled PC, once you begin adding on the inevitable customized hardware, the costs go up anyway. Suddenly building your own computer starts looking cheaper. And don’t forget–those super-cheap PCs are bare-boned systems. Unless you need a computer only for basic word processing and e-mail, you will probably have to upgrade anyway.
Building your own PC can be a great learning experience. You will gain a better understanding of how the various components work together, knowledge that can be useful for troubleshooting. If your computer ever breaks down, you may be able to pinpoint the problem and fix it yourself, saving money on expensive repair bills.
You are virtually guaranteed to get the best computer when you build your own system. Big retailers often use cheaper OEM (Original Equipment Manufacturer) components to cut down on costs. Components like these can compromise the performance of a computer system. Although you can buy OEM components yourself, the trade-off in reliability and stability is usually not worth it. Brand name components are just a bit more expensive, but are well worth the cost.
Disadvantages
The major disadvantage in building your own PC is that you don’t get a system-wide warranty. For example, if a malfunctioning motherboard fries your memory chips, you may not be able to get compensation for the damaged memory. If something like this happens with a store-bought system you could probably get the whole computer repaired under the warranty.
However, if you buy all your components at the same time from the same retailer, you are more likely to be compensated for this kind of situation.
Time is, of course, a factor. But it is educational time. And if you enjoy tinkering at all, it counts as fun time as well.
The Bottom Line
Building your own PC has a lot to offer. You’ll be assured of getting the best components available, which translates to the best and most reliable computer for your money. You will learn about computer components and how to choose parts with the best performance. When it comes to servicing your computer, you may be able to solve and fix the problem yourself.
Oh, and one final advantage. The bragging rights of telling your friends that you built your own computer. Priceless!

More Questions To Ask A Computer Training School Before Paying

More Questions To Ask A Computer Training School Before Paying

The decision to attend a computer training school is one of the most important you’ll ever make, and even more important is which one to attend. Asking the right questions can give you an idea of whether a given IT school is a good investment. An earlier article I wrote on this subject was so popular that I thought I’d offer some more advice on the questions to ask before you write that check or take out that loan.

If the school offers a placement service, ask to talk to the people working in that department and ask them how they go about placing graduates. Most schools offer a list of companies that they’ve placed students with. Get this list and start calling some of these companies. Ask to speak to their HR department, and ask them for their opinion of the school. Even if they don’t say a lot, their tone of voice can speak volumes.

Ask to meet some of their teachers, and don’t be afraid to ask them how long they’ve taught at that particular school. If the average teacher has been there a while, that’s a good sign. If there seems to be quite a bit of turnover at the school, that’s not as good a sign.

Another key area is the availability of the computer labs during class and after the class is over. Speaking from experience, I can tell you that getting hands-on experience with the various software and hardware you’ll be working with in the field is the #1 way to get ahead – just reading books won’t do it. If you’re taking a router class, does the school have real routers for you to work on? If you’re taking a PC repair class, are there plenty of PCs for everyone in your class to work on, or do you have to share?

You want classes that offer hands-on experience during class, and you should be able to get into the computer labs after class. You may not be able to use the labs at night if the school offers night classes, but again I speak from experience – the time you spend in the computer labs after class is just as valuable as the time you spend in class. Make sure the labs will be available after class – and then get in there and work!

Ten Courses Of Study If You Want To Be Your Own Boss.

For many Americans, an important component of the American Dream is the possibility of hard work turning into financial fortune. The career exploits of such self made magnates like Andrew Carnegie, Lee Iaccoca and Donald Trump are examples for many.
The idea of being self-employed appeals to many people who want the possibility of unlimited income, a flexible schedule and perhaps the opportunity to work from home. If you’re one of these people, having the proper training, especially in a growth industry, is very important. Consider these ten courses of study, if you want to be your own boss.
Creative Careers
The personal computer has made it much easier to enter the marketplace in many professions. Training in graphic design, multimedia design and web design allow you to work from home, or as your clientele increases, out of an office. Education in these skills can also create opportunities for you to work as an employee, or contractor. These creative jobs are very much in demand, particularly as advertising spending has increased as the economy has improved.
Mechanical Careers
If you like to fix things or work with your hands, there are some great, lucrative training programs that will allow you to do this type of work for a career. Most of these jobs require you to work for someone else first, either to gain skills training or the money to go off on your own. A career in HVAC (heating, ventilation, air conditioning), home appliance repair, electrical installation/repair or auto body repair are all great ways to make your hands create a living for you.
Service Careers
There are many service careers available as well for the self-employed. Home healthcare is one such growing field. Nurses, both RNs and LPNs, are in wide demand. Another career field that is growing is court reporting and closed captioning. The growing legal system and new Federal laws designed to benefit the hearing impaired are driving growth in these categories.
In addition to having the skills to perform your chosen business, you need the business skills as well. Sales and marketing are in first order, while organization and administrative skills will keep your clients and the IRS happy.

What Anti-Virus Software Consist Of

What Anti-Virus Software Consist Of

Anti-Virus software consists of computer programs that attempt to identify, thwart, and eliminate computer viruses and other malicious software (Malware). Anti-Virus software typically will use two different techniques to accomplish the following things, Examining,also known as scanning your files on the computer to look for familiar viruses that will match definitions in a virus dictionary.

The Anti-Virus software will also identify suspicious behavior from any computer program which might indicate if it has infection.Some of these analysis may also include data captures,port monitoring and other methods as well.Most of the commercial Anti-Virus software uses both of the following approaches, with an emphasis on the virus dictionary approach.

In the virus dictionary approach,when the anti-virus software looks at a file, it refers to a dictionary of known viruses that the authors of the anti-virus software have identified.If a piece of code in the file matches any virus that is identified in the dictionary,then the anti-virus software can take one of the following options.

1. Attempt to repair the file by removing the virus itself from the file.

2. Quarantine the file(such that the file remains inaccessible to other programs and it’s virus can no longer spread).

3. Delete the infected file. To achieve consistent success in the medium and long term,the virus dictionary
approach requires periodic downloads of updated virus dictionary entries.

As civically minded and technically inclined users identify new viruses “in the wild”,they can send the infected files to the authors of anti-virus software,who then include information about the viruses that are new in their dictionary.Dictionary-based Anti virus software typically examines files when the computers operating system creates,opens,closes or e-mails them.

In this way it can detect a familiar virus very quickly upon receipt.Note to that a systems administrator can typically schedule the anti virus software to examine (scan) all files that are on the computer’s hard disk on a regular basis.

Although using the approach of the dictionary can effectively contain virus outbreaks in the right circumstances, anti virus authors have tried to stay a step ahead of such software by writing ” oligomorphic,” “polymorphic” and more recently “metamorphic” viruses, which encrypt parts of themselves or otherwise modify themselves as a method of disguise,so as to not match the virus’s signature in the dictionary.

Anti virus programs come in many different types and it is important that you understand all of those types before choosing to purchase any for your home or office computer system. Research this some more before choosing which type would be most beneficial to you. Keeping your computer functioning properly is really very important because they sure do cost us all plenty of money!

Purchase an anti virus program for your computer now if you do not currently have one for your personal computer, otherwise you are going to be out a great deal of money once your computer becomes invaded by bugs!
