Although there are many things that can affect the performance of your computer, there are a few simply things you can do each month to help keep your computer running at maximum performance. This article will focus on two problems that impact the performance of your computer and will then explain what you can do about it.

Problem #1: Computer Hard Disk Files

Your computer is always writing information to your hard disk, no matter what you do. Your computer attempts to keep all file information in the same location on your hard drive. As you add and delete files, blank spaces are left between your files. As you add new programs or files, your computer tries to use these blank spaces.

Over time, this reading and writing of files can affect the way your computer performs. The files eventually become scattered in multiple locations on your hard disk rather than in the same location.

Your computer will still find the information. However, the more scattered the information becomes on your hard drive, the more accesses your computer has to make to find (and gather) the information. This requires your hard disk to work harder and do more reading/writing than is necessary. It will slow down your computer by as much as 200% and causes increased wear and tear on your hard drive.

Problem #2: Spyware

If you use the Internet, at some point you will download a file or software program onto your computer. Sometimes you will know something is being downloaded to your computer. Other times you will have no idea. (Although this article will not talk about small files called “cookies”, you may want to look up information on this subject. Cookies are written onto your computer from the Internet.)

Free computer programs (often referred to as Freeware) are a big hit on the Internet. Every day thousands of users download these “free programs”. Although there are some great freeware programs, these programs often have advertisements or tracking code associated with their use. The term “Spyware” refers to programs that gather information about your computer and (Internet) surfing habits without your knowledge. This information is then sold to a third party company as a means of generating revenue.

The problem with Spyware is that it also impacts the performance of your computer. It can make your computer very sluggish and unresponsive.

Three Steps to Improved Computer Performance

Now that we’ve discussed two problems that affect the performance of your computer, let’s discuss three things you can do to get your computer performance back to normal. You should do these three steps in the order presented. Ideally, you should repeat them about once a month or whenever you notice a change in your computer’s performance.

Step #1: Delete Spyware

The first thing you should do is to delete spyware files or programs from your computer. To do this, you can use a free software program such as Ad-Aware SE Personal Edition from LavaSoft. To get the program, go to www.download.com and search for “Ad-Aware SE” (without the quotes). Select “Download Now” and follow the installation instructions. Once the program is installed, you can scan your computer for spyware files. Then, you can select and delete them from your computer.

Note #1: Always be sure to use the “Check for updates now” option to keep your program current.

Note #2: You need to be aware that when you delete spyware files, some of those “free” programs you downloaded may not continue to work correctly. If you have a program you’ve downloaded and want to continue to use, check very carefully what you select to delete from the “Scanning results” once the scan has been completed.

Step #2: Clean up your Hard Disk

Once the spyware is removed, you need to clean up temporary and unwanted files from your hard disk. To do this on your windows PC, select the start option in the lower left hand corner of your computer screen. Then, select the program option. Under the program option, select “Accessories”. Under the “Accessories” option, select “System Tools”. From the System Tools option, select “Disk Cleanup”.

Select the drive you want to clean from the pull-down menu and select OK. Usually, this is Drive C. If you have more than one hard drive, select one at a time. This program will then scan your computer for files that could be erased from your computer. You can safely erase all temporary and Recycle Bin files. You can also check the box of any other files you want the program to erase.

Step #3: Defrag your Hard Disk

Once all the spyware and temporary files are removed, you need to defrag your hard disk. This process simply rewrites your computer files so they are no longer scattered all over your hard disk, but are written in the same location for quick sequential access.

To defrag your hard disk on your windows PC, select the start option in the lower left hand corner of your computer screen. Then, select the program option. Under the program option, select “Accessories”. Under the “Accessories” option, select “System Tools”. From the System Tools option, select “Disk Defragmenter”. First, select the hard drive from your computer. Usually, this is Drive C. However, many computers have multiple hard drives. Select one at a time.

You can select “Analyze” to have the program check out the hard drive and see if it needs to be defragged. The program will prompt you at the completion of its analysis. Use the defragment option as prompted.

Note: If you’ve never used this option before, I would recommend that you select the defragment option.

Once, you’ve completed these three steps, your computer and hard disk should be able to operate at maximum performance. Don’t forget to repeat these steps at least once a month or whenever you notice a change in your computer’s performance

Everybody just has to have a computer these days. Life without a computer is unimaginable. I am sure that there are those who feel that life without a computer is impossible. There was a time when food, clothing and shelter were the only necessities that man had. Fast forward to today, and we have yet another necessity to add to that list — Say hello to the friendly neighborhood computer.

Of course, now that you have a computer, you have to work on it. Certainly, there must be people who keep their PCs covered throughout the year, removing the covers once a month only to check if it is still working. But you don’t need me to tell you that such people are exceptions, not the rule. So for all those of us that have to be on our computers everyday, how do we make sure that our computers are working perfectly? This is where computer tips & tricks come in.

One important aspect that requires you to use computer tips & tricks is in ensuring that your computer does not become unnecessarily slow. We all want our computers to work at the speed of light. You can ensure that your computer remains quick by carrying out Scandisk and Defrag — two methods that are used to make your computer faster.

The function of Scandisk is to find and correct errors on the hard disk of a computer. Defrag performs the task of making sure that data files that have been stored across the disk are now reorganized in a continuous order. Defrag helps free space in which new data can now be stored. Both Scandisk and Defrag should be carried out regularly to make sure that your computer’s hard disk is both error-free and not overloaded.

These two operations are among the most important of the many gazillion computer tips & tricks that computer experts recommend you to make use of. If you have embarked on a journey to find some of the best computer tips & tricks, you are not going to return empty-handed. With a large percent of the population of the world having become dependent on computers technical snags become inevitable. And the consequence of these snags is that one finds cures and way of preventing them.

So don’t lose heart if your computer is threatening to crash. Consult a computer expert or a reliable online website and find some great computer tips & tricks to take care of your PC problems.

It seems that the time that it takes for computers to become obsolete is shortening more than ever. If you go out and purchase a top-of-the-line computer, it is very likely that in less than six months it will no longer be considered top-of-the-line. If you currently have a computer and you want it to be able to perform more functions, you don’t have to get rid of it and spend a lot of money on a new system. You can simply purchase components to upgrade your computer. If you seriously consider upgrading your computer, now is a perfect time to do so. As with computers, prices of computer components are at an all-time low. Depending on the type of specifications you’re after, you can spend as little as three hundred dollars to update your desktop or laptop computer.

Finding all the components you need to upgrade your own computer system is as easy as visiting findcheapcomputers.com. This website features detailed information about parts and includes a buyer’s guide to make buying your components a snap. The first task that you need to perform to upgrade your computer system is to make a list of the computer’s specifications. If you’re not sure what specs you want the system to have, you can consider what you will do most with the computer and then generate a list of specifications. People typically choose to upgrade their existing computer systems because it does not include a particular component to enable them to perform a particular task.

A processor is an important component in your computer. Whether or not you should upgrade your processor depends on the tasks you will perform with the computer and the type of processor that currently exists in your computer. If the system you are planning to upgrade does not use one of the fast processors on the market, you may want to invest in a motherboard bundle that includes a motherboard, CPU, and fan. These bundles generally cost less than if you were to buy the parts separately. Of course, you could purchase an Intel Celeron with a speed of 2.6 gigahertz or an AMD Athlon 2700+. Both of these processors are sufficient for general computer use as well as browsing the Internet and gaming.

In addition to the processor, you will probably want to upgrade your system with memory, a graphics card or video card, a monitor, and keyboard and pointing device. Finding cheap computer deals of these components should be easy since activities that require high-quality video such as gaming are very popular. The important thing to remember when shopping for these components is that you need to make sure they are compatible with your system. For example, an AGP graphics card is an excellent choice if you plan to do a significant amount of gaming because it processes graphics faster. However, your motherboard will need to have an AGP slot. If you’re not sure which components are most compatible, the website findcheapcomputers.com features information about computer components that are not only compatible with most systems, but that are also cheap.

As more and more people are becoming comfortable using their computers at school, home or in the office it’s only a matter of time before they encounter a computer virus. Here are our top 10 steps to protect you from computer viruses.

Use a high quality anti-virus program. There are many different anti-virus computers programs on the market some of them are better than others. Look to reputable computer magazines or websites for ratings to help you find the one that matches your needs.

Always use your anti-virus software. Make sure your anti-virus software is always turned on and scanning, incoming and outgoing email messages, and any software programs you run.

Keep your antivirus programs up to date. Most programs come with a yearly subscription make sure you take advantage of the updates. More advanced programs allow you to schedule updates or full system scans for “off hours” like 2AM when you aren’t likely to be using your computer.

Keep your computer up to date. From time to time operating systems fall victim to security holes or issue updates. Make sure you check periodically to make sure you are running stable up to date versions of your software.

Backup your data regularly. Most windows computer users keep their documents in the “My documents” folder. This makes it easy to back up all of your important documents. Make weekly or monthly copies to CD or USB drives.

If you use floppy disks or USB drives on public computers like your school computer lab, Kinko’s, or even digital photo printing store make sure you scan them for viruses. Public computers are notorious for not being up to date and properly protected.

Be wary of email attachments. Treat any email attachment as potentially dangerous. Never open attachments from people you weren’t expecting. Also be careful of attachments from people you know but weren’t expecting. Many computer viruses replicate themselves by reading the contacts from an infected computer.

Use text email if possible. While HTML email is prettier and allows you more control over formatting it also can carry computer viruses. If you use text based email the only way to get a virus is by opening an attachment.

Use downloaded freeware and shareware files or software with caution. Try to download them from popular reputable sources that scan the programs before they are uploaded. To make sure you are safe scan the program before you install it on your computer.

Be wary of links in IM or instant messaging software. Don’t accept invitations from people you don’t know and never click a link from someone you don’t trust, they can easily redirect you to another website that will try to install a virus on your computer system.

Your computer is as slow as molasses. Your mouse freezes every 15 minutes, and that Microsoft Word program just won’t seem to open.

You might have a virus.

Just what exactly is a virus? What kind is in your computer? How did it get there? How is it spreading and wreaking such havoc? And why is it bothering with your computer anyway?

Viruses are pieces of programming code that make copies of themselves, or replicate, inside your computer without asking your explicit written permission to do so. Forget getting your permission down on paper. Viruses don’t bother to seek your permission at all! Very invasive.

In comparison, there are pieces of code that might replicate inside your computer, say something your IT guy thinks you need. But the code spreads, perhaps throughout your office network, with your consent (or at least your IT guy’s consent). These types of replicating code are called agents, said Jimmy Kuo, a research fellow with McAfee AVERT, a research arm of anti-virus software-maker McAfee Inc.

In this article, though, we’re not talking about the good guys, or the agents. We’ll be talking about the bad guys, the viruses.

A long, long time ago in computer years, like five, most viruses were comprised of a similar breed. They entered your computer perhaps through an email attachment or a floppy disk (remember those?). Then they attached themselves to one of your files, say your Microsoft Word program.

When you opened your Microsoft Word program, the virus replicated and attached itself to other files. These could be other random files on your hard drive, the files furthest away from your Microsoft Word program, or other files, depending on how the virus writer wanted the virus to behave.

This virus code could contain hundreds or thousands of instructions. When it replicates it inserts those instructions, into the files it infects, said Carey Nachenberg, Chief Architect at Symantec Research Labs, an arm of anti-virus software-maker Symantec. Corp.

Because so many other types of viruses exist now, the kind just described is called a classic virus. Classic viruses still exist but they’re not quite as prevalent as they used to be. (Perhaps we could put classic viruses on the shelf with Hemingway and Dickens.)

These days, in the modern era, viruses are known to spread through vulnerabilities in web browsers, files shared over the internet, emails themselves, and computer networks.

As far as web browsers are concerned, Microsoft’s Internet Explorer takes most of the heat for spreading viruses because it’s used by more people for web surfing than any other browser.

Nevertheless, “Any web browser potentially has vulnerabilities,” Nachenberg said.

For instance, let’s say you go to a website in IE you have every reason to think is safe, Nachenberg said.

But unfortunately it isn’t. It has virus code hidden in its background that IE isn’t protecting you from. While you’re looking at the site, the virus is downloaded onto your computer, he said. That’s one way of catching a nasty virus.

During the past two years, another prevalent way to catch a virus has been through downloads computer users share with one another, mostly on music sharing sites, Kuo said. On Limewire or Kazaa, for instance, teenagers or other music enthusiasts might think they’re downloading that latest Justin Timberlake song, when in reality they’re downloading a virus straight into their computer. It’s easy for a virus writer to put a download with a virus on one of these sites because everyone’s sharing with everyone else anyway.

Here’s one you might not have thought of. If you use Outlook or Outlook Express to send and receive email, do you have a preview pane below your list of emails that shows the contents of the email you have highlighted? If so, you may be putting yourself at risk.

Some viruses, though a small percentage according to Nachenberg, are inserted straight into emails themselves.

Forget opening the attachment. All you have to do is view the email to potentially get a virus, Kuo added. For instance, have you ever opened or viewed an email that states its “loading”? Well, once everything is “loaded,” a virus in the email might just load onto your computer.

So if I were you, I’d click on View on the toolbar in your Outlook or Outlook Express and close the preview pane. (You have to click on View and then Layout in Outlook Express.)

On a network at work? You could get a virus that way. Worms are viruses that come into your computer via networks, Kuo said. They travel from machine to machine and, unlike, the classic viruses; they attack the machine itself rather than individual files.

Worms sit in your working memory, or RAM, Nachenberg said.

OK, so we’ve talked about how the viruses get into a computer. How do they cause so much damage once they’re there?

Let’s say you’ve caught a classic virus, one that replicates and attacks various files on your computer. Let’s go back to the example of the virus that initially infects your Microsoft Word program.

Well, it might eventually cause that program to crash, Nachenberg said. It also might cause damage to your computer as it looks for new targets to infect.

This process of infecting targets and looking for new ones could eventually use up your computer’s ability to function, he said.

Often the destruction a virus causes is pegged to a certain event or date and time, called a trigger. For instance, a virus could be programmed to lay dormant until January 28. When that date rolls around, though, it may be programmed to do something as innocuous but annoying as splash popup on your screen, or something as severe as reformat your computer’s hard drive, Nachenberg said.

There are other potential reasons, though, for a virus to cause your computer to be acting slow or in weird ways. And that leads us to a new segment – the reason virus writers would want to waste their time creating viruses in the first place.

The majority of viruses are still written by teenagers looking for some notoriety, Nachenberg said. But a growing segment of the virus-writing population has other intentions in mind.

For these other intentions, we first need to explain the “backdoor” concept.

The sole purpose of some viruses is to create vulnerability in your computer. Once it creates this hole of sorts, or backdoor, it signals home to mama or dada virus writer (kind of like in E.T.). Once the virus writer receives the signal, they can use and abuse your computer to their own likings.

Trojans are sometimes used to open backdoors. In fact that is usually their sole purpose, Kuo said.

Trojans are pieces of code you might download onto your computer, say, from a newsgroup. As in the Trojan War they are named after, they are usually disguised as innocuous pieces of code. But Trojans aren’t considered viruses because they don’t replicate.

Now back to the real viruses. Let’s say we have Joe Shoo virus writer. He sends out a virus that ends up infecting a thousand machines. But he doesn’t want the feds on his case. So he instructs the viruses on the various machines to send their signals, not of course to his computer, but to a place that can’t be traced. Hotmail email happens to be an example of one such place, Kuo said.

OK, so the virus writers now control these computers. What will they use them for?

One use is to send spam. Once that backdoor is open, they bounce spam off of those computers and send it to other machines, Nachenberg said.

That’s right. Some spam you have in your email right now may have been originally sent to other innocent computers before it came to yours so that it could remain in disguise. If the authorities could track down the original senders of spam, they could ***** down on spam itself. Spam senders don’t want that.

Ever heard of phishing emails? Those are the ones that purport to be from your internet service provider or bank. They typically request some information from you, like your credit card number. The problem is, they’re NOT from your internet service provider or your bank. They’re from evil people after your credit card number! Well, these emails are often sent the same way spam is sent, by sending them via innocent computers.

Of course makers of anti-virus software use a variety of methods to combat the onslaught of viruses. Norton, for instance, uses signature scanning, Nachenberg said.

Signature scanning is similar to the process of looking for DNA fingerprints, he said. Norton examines programming code to find what viruses are made of. It adds those bad instructions it finds to its large database of other bad code. Then it uses this vast database to seek out and match the code in it with similar code in your computer. When it finds such virus code, it lets you know!

Asterisk phone systems are an excellent, fully integrated VOIP PBX solution for businesses of all sizes. The set up eliminates the tremendous cost of setting up a traditional PBX system. This high cost often eliminates the possibility of using PBX for small businesses, but with Asterisk, even the smallest business can have all of the benefits of PBX in their office without spending money they do not have.

What Is Asterisk?

Asterisk is an open source software PBX that can be used by businesses and individuals alike. It is designed to run on Linux, but it can run on other platforms as well, including Windows. Asterisk was developed by Digium, Inc., who also sells the hardware necessary to set up Asterisk phone systems. Compared to other PBX options, Asterisk is incredibly affordable and has many features that are hard to find elsewhere.

Benefits of Asterisk in the Office

Besides the fact that it costs thousands of dollars less than a traditional PBX system, Asterisk provides its users with numerous other benefits. Since Asterisk phone systems are VOIP PBX systems, they use broadband connections to connect the telephone network to the traditional global telephony network. Calls can still be made and received in the same manner that they are with a traditional PBX system. Additionally, because the connection is made through the Internet and not the phone line, employees that work remotely can be connected directly to the office PBX through their Internet connections. When someone calls your office and chooses extension 10, that extension could actually be your home-based worker, and the customer would be none the wiser.

For large businesses that have locations in several geographical areas, using asterisk will allow the various offices to connect over the network. This can eliminate much of the expense of conference calls a company spread over several states usually faces. Additionally, employees who must travel frequently can stay connected to the office PBX system as long as they have an Internet connection.

Asterisk phone systems allow every extension to have its own voicemail box. These voicemail boxes are connected to the employee’s email accounts, so no one will ever miss a message again.

If you should ever have a problem with your Asterisk system, you can easily get help directly from Digium. They have friendly Asterisk consulting professionals that will help you get the system up and running as quickly as possible. You can call to ask questions about bugs that you find, and they are happy to help, as this type of feedback helps them improve the software for future users.

Asterisk supports a variety of VOIP protocols. Among the protocols it accepts are MGCP, H.323, and SIP. The program can connect IP phones to the traditional phone line easily. This flexibility makes the system easy to integrate into established businesses.

If needed, Asterisk phone systems can interface with traditional telephone lines. The product comes with several high-end features, such as voice recognition system integration, call data record, and text-to-speech system integration. All of these features make it one of the best PBX products available.

Benefits of Asterisk for Customers

Your employees are not the only ones who benefit from Asterisk phone systems. Your customers will benefit as well, both directly and indirectly, when you implement this system. It has features that are found in the most expensive products on the market, such as on-hold music that supports both MP3 and streaming media. Customers will have shorter wait times because the call queues allow agents to monitor the queue while they take the incoming calls, so they can shorten the calls if needed.

Asterisk phone systems offer the best of both worlds to their users. They provide a plethora of features to the business at a fraction of the cost of their traditional competition. There are other VOIP PBX options out there, but Asterisk is the oldest and most well established, making it the preferred choice among many business owners.

Rapid and trustful communication systems have become a norm in the modern world. For this reason, people are increasingly dependent on communication tools like the internet and the telephone which are the two major branches of the communication industry.

The telephone allows you to talk directly to anyone in any part of the world be it your friends, family or your clients. It is not only quick it is quite dependable too. This is such an important tool that now it has become one of the basic necessities in every home and business. Businesses depend quite a lot on this mode of communication and their life would get stranded without connectivity through a telephone.

The internet has also capture the world by storm through its ability to provide super fast and consistent means of communication. The amazing factor to the internet is all the applications that it offers for communication can be accomplished with very low cost. People can keep connected with other people through emails and chat.

The modern times has seen another advance in the field of communication by providing the latest communication tool, the Voice over Internet Protocol (VoIP) or the Internet Voice. This is very similar to talking over the regular telephone but it is much more advanced. This has become so popular in the modern times that people are seriously contemplating eliminating the use of the regular telephone and switching over entirely to the VoIP system.

VoIP is far superior to the conventional telephone in that it provides many more features and advantages which the latter cannot even dream about. VoIP is through the internet and the voice signals are converted into digital format and then transmitted to the other person. The digital format of the voice signals ensures that there is no loss of voice quality and the communication is quicker and crystal clear as compared to a regular telephone conversation.

A great attraction that VoIP provides is the cost factor. Using this system, a person can make long distance calls to any other place in the world at a very low price or even for free. When compared to calls made long distance over the regular telephone, the communication is much faster, clearer and much cheaper when using the VoIP service. So, you will end up with lesser bills over the month in comparison to using the regular telephone line.

VoIP provides other advantages too. Let us suppose you require a PBX in your organization. If you purchase one to be used with your regular telephone line, it will be quite expensive. But, if you purchase one and use it over the VoIP system, it will be much cheaper and highly consistent. The functioning of the PBX system is similar in both the modalities but if the PBX is used with the VoIP system, it will be through the internet rather than through the telephone line.

VoIP is easily obtainable in today’s times. You can find many service providers marketing the services on the internet who will provide business VoIP. But, if the purpose is to install VoIP system at home or if your intention is to make VoIP a career path, you will have to learn about setting up the VoIP system.

Installing a VoIP system is taught by Cisco Training Courses which has several such courses, one of them the Asterisk VoIP Hosted PBX.

If you opt for this course, you will be provided with all the training materials you will require to understand the process of setting up a VoIP system in any kind of setup. VoIP is beneficial for residential and business purposes. But, Asterisk VoIP Hosted PBX is more suitable for big organizations in meeting their communication needs.

Cisco provides all relevant information about the various VoIP PBX systems that are available and their utility. Using the Asterisk VoIP Hosted PBX, one can integrate all the phone lines in the organization into a single channel for communication that uses the internet to route the calls.

IP PBX is a powerful tool for communication within any office setup. Using this piece of hardware, the entire organization’s communication needs can be met and easily regulated.

If you are intending to take up VoIP as a career path, you need to contemplate about Cisco VoIP Training Courses. The advantage this course provides is the hands-on experience using the Asterisk VoIP Hosted PBX. VoIP is definitely a good career path what with the amount of popularity it is gaining by the day and the pace at which it is eliminating the need for regular telephones.

If you are going to work and do a lot of browsing on the Internet, the first thing you need to learn is how to take care of your computer.

It is far better that you take the trouble to look after your computer regularly, rather than have it freeze or crash when you lose everything on it, at which time you’ll have to pay out a lot to have it fixed.

Here are some tips to prevent disasters:

1) Set your virus checker to update itself automatically. This way, it is always updated with the latest protection.

2) Scan your computer daily when you finish working on it.

3) If on a certain day you happen to download many pages, software, programs, zipped files, exe files, etc., immediately after downloading everything, scan your computer. This way, just in case a virus existed in anything you downloaded, you will catch it in time before it infects your entire Hard Drive.

4) Use your online scanner to scan your computer once a week.

5) Use your adware/spyware checker once a week.

6) Do not open any attachments in emails from people you do not know.

7) Do not open any attachments even from people you do know, if you are not expecting anything from them.

A virus could replicate itself to everyone on the address book and send itself out by email, without the owner even knowing this has been done.

9) Do not download free music on the Internet – these free sites are always infected.

10) Do not download any free games from the Internet.

11) Adult sites are particularly prone to viruses.

12) Back up all your data on a daily basis. Use floppy disks, flash drives, memory sticks, zip disks, CD-ROMs, etc.

13) Print out contracts, payment forms, agreements and all legal documents and file them away in a ring-binder.

14) Try not to keep anything to do with your finances, payment details, payment processor passwords, credit card details, etc. on your computer.

15) A hacker could easily access all these details, if they are anywhere on your computer.

Sadly, despite all these precautions your computer might still get infected, as the people who invent these malicious programs are getting even sneakier.

When this happens, the easiest way to rid your computer of a virus is by rebooting your computer. This is not as difficult as it may sound, and if you learn how to do this yourself you could save yourself hundreds of dollars in repair bills.

Computer errors are very common and every computer user may face different kinds of issues so they should learn about the solutions of the common computer related problems. The common factors that cause problems in computer are viruses, spyware, Trojan horses, adware, corrupted registry, faulty hardware, low memory, low capacity hard disk, low CPU speed and stuffing computers with large number of software applications. In this article, I have compiled a list of the most common computer problems and their solutions.

Computer is very slow

This is very common issue and it arises due to the several factors such as too many programs running at the startup, low RAM, low processor speed, spyware running as a background application, errors in the Windows registry and the buildup of the garbage files on the hard disk. Scanning your computer with an up-to-dated anti virus and anti spyware program, cleaning and repairing Windows registry, increasing memory, deleting temporary files, deselecting the programs at startup and uninstalling unwanted software applications can solve this problem to a very large extent.

Network Server is not accessible

In a networked environment every computer depends on the server for logon authentication, files access, internet and printing access and sharing server resources. The downtime and the communication failure with the server are very problematic and frustrating for the users. Check both end of the network cable and make sure that the attached RJ-45 connectors are properly plugged into the LAN card and hub/switch. Ping the server’s IP and make sure you get the reply from server. Ensure that your server is on and working fine. A large number of the running applications on the server and simultaneous access to the server from a number of users can slow down the performance and speed of the server. Scan your PC with an up-to-dated antivirus program because certain viruses and spyware are responsible for the communication failure. Replace your LAN card with new one and assign different IP address and try to connect with the server.

Computer locks up or freezes

Missing .dll files, viruses, faulty registry, defective RAM and spyware slows down the performance of the server and it locks up frequently. Scanning PC with the anti virus and anti spyware program, cleaning and repairing registry and increasing RAM can solve this issue.

Computer won’t boot

Faulty power cable, power extension and power supply all contributes to this problem. Checking one by one each of the above components can pinpoint the problematic part. Simply replace that part with new one and your compute is okay.

Computer reboots itself

Defective cooling fan, power supply, RAM, viruses and spyware can cause this to happen.

Memory usage is maximum in computer

Either the memory is less than the recommend memory to run certain applications, swap memory chips with each other, scan your computer for viruses and spyware, increasing the page file and physical memory can overcome this problem.

Browser’s home page has changed itself

This is most likely a spyware problem and scanning computer with an up-to-dated anti spyware program can fix this issue.

Computer’s clock losing time

If you see that your computer’s clock is losing time frequently replace your CMOS battery.

My computer can’t get connected to internet

Check IP address, gateway address, scan your PC for viruses and spyware, check network cables and make sure that server’s or gateway’s firewall application is not blocking http requests from your PC.

Computer making noises

Faulty RAM, VGA, hard disk, Sound card, Processor and other components produce noises. Make sure that each hardware device is properly connected inside the PC and if the problem is still not resolved then replace the faulty hardware component with new one.

Do you remember when you were a kid, and saw your first automobile? To the older crowd, the answer might be yes. To them, the first automobile was most-likely an object of wonder. It wasn’t necessarily a thing to be feared, just an unknown. It was something that you had heard of, but hadn’t had any experience with it. It wasn’t scary.

To most everyone else, you don’t remember your first time you saw an automobile, because they’ve just always been around. You aren’t scared of them because you are familiar with them. The youngest generation of youth feels the same way about computers.

Many of you may remember the first time you saw a computer. It was a strange thing that you weren’t familiar with. To some of you, it was exciting. To others, it wasn’t. But somewhere along the line, you decided that using a computer was something that only younger (or more “gifted”) people should do.

We’re past the age when cars are for only the wealthiest. Now, everyone has a car. In previous days, it was perfectly fine to walk everywhere. Some still do that, but most have learned to drive. In these days, there are still some who can “get around” just fine without the use of a computer, but most people use them multiple times in a week.

In the same way, however, that most people see cars, the younger generations see computers. Computers are not something to fear. They’re only something that you’re not familiar with. That doesn’t make them bad. And it doesn’t make YOU bad.

So in the same way you have gotten used to cars, go ahead and have some fun with computers. Play around. You won’t break it, just like you didn’t break your car the first time you got in it. Go for it! Have Fun!
