Troubleshooting, as it is commonly defined, is a form of solving problems especially those found in systems, machines, and devices. Its definition alone exhibits the importance of such activity mainly because through it, expenses on repairs and buys are lessened and more importantly, a device’s usage is maximized. It is important to remember that at the very instant that a device is bought; issues could instantly go with it. This explains why it is greatly important to know how to troubleshoot these ever increasing system, machine, and computer problems. Troubleshooting lessens expenses brought by repairs and even the need of buying new systems and computers knowing that through it, problems are given immediate solutions. Also, through troubleshooting, uses and benefits of an involved software or device are maximized which as well makes its cost worth it and thus avoiding serious problems such as system failure or device malfunction and breakdown.
Troubleshooting computer network is among the most important job descriptions of the network administrators, system administrators, network technicians and the IT consultants. A computer network can have different kinds of problems such as it can be infected with virus and spyware, attacked by hackers, accessed by unauthorized users and may face connectivity failure issues due to the faulty network devices or configurations. Following is a list of the basic network troubleshooting commands that are built-in the Windows based operating systems and UNIX etc. The right use of these troubleshooting commands can helps a lot in diagnosing and resolving the issues with your computer network.
Ping is the most important troubleshooting command and it checks the connectivity with the other computers. For example your system’s IP address is 10.10.10.10 and your network servers’ IP address is 10.10.10.1 and you can check the connectivity with the server by using the Ping command in following format.
At DOS prompt type Ping 10.10.10.1 and press enter
If you get the reply from the server then the connectivity is ok and if you get the error message like this “Request time out” this means the there is some problem in the connectivity with the server.
IPconfig is another important command in Windows. It shows the IP address of the computer and also it shows the DNS, DHCP, Gateway addresses of the network and subnet mask.

One of the most common problems that an individual encounters with their MP3 player is incompatible file formats. All MP3 players can read files in .mp3 format and most can also accommodate .wma formats. Even if a music file doesn’t match these extensions, there are several software programs that allow an individual to convert file formats to suit their MP3 player. Compatible files are the most important thing to consider with an MP3 player because without them, the music will not play.
If you’re MP3 isn’t playing an entire song, check to make sure that the entire track was downloaded properly. Sometimes a computer glitch or simply an oversight in downloading a portion of a track rather than the entire track will present a problem. If the complete track was downloaded and working properly before being downloaded onto the MP3 player, there may be a hardware problem with the player itself.
When downloading any file, including an MP3 music file, make sure that the download is free of any viruses and was obtained from a reputable source. By running a virus check on the file prior to opening it, an individual may be able to protect themselves from a computer virus. If a file contains a virus of some type, it may cause operational problems with the MP3 player as well. Before it even makes it to the MP3 player, however, any present virus will have already infected the computer. Your best bet? Purchase a reliable anti-virus software program and use it regularly on every file download.
If a problem arises with an MP3 player and cannot be resolved by first consulting the user’s manual, which should have been included in the packaging, individuals are urged to contact the manufacturer for possible warranty information. If the MP3 player is not covered under warranty, the company may still be able to repair or replace any defective part at the customers expense. Otherwise, a local electronic retailer may be able to correct the problem or recommend that the MP3 player be replaced altogether.
He can give a lot of technical advice to the client in various things like Internet security, data storage, right use of various computer applications etc. This will work out to be a mutually beneficial relationship between the client and the service giver. All those who own a PC are bound to need PC repairs now and then, and for these repair requirements they would need a PC technician. While this is an indisputable fact a technician can do much more than repair a PC. So far as he has got a good rapport with the PC owner, he can forestall a lot of repairs by helping him to maintain the computer well.
One of the ways in which a PC technician can help is by emphasizing to the client the need for data protection. With relation to the Internet, there is a lot that a client has to know about firewalls, securing of passwords, problems with an unsecured router etc. If his PC technician can explain to him all these and guide him on how to use the Internet in a secure way, the computer owner will be able to prevent data exposure to a great extent.
In most cases, computer users try to get the help of a PC technician only when there is an emergency need for some PC repairs. Instead of that they can tie up with a technician, which can involve technical advice as well. Even if he charges a little extra for it, it will work out as a mutually beneficial package. Under this agreement, the technician can give his client detailed advice on the need for surge protection, power backup requirements, registry cleaning, virus protection, and the need to continuously back up data to save data.
The need for data backup can never be overemphasized. Data can be stored in external storage devices like eSATA or a USB flash drive. For those who find even this inconvenient, there are online provisions for data storage. A PC technician can obviously guide a computer owner on the advantages and disadvantages of using different data storage facilities and on the cost effectiveness of each.
Online data storing facilities have many advantages over external data storage devices. When the data is stored online, the user does not even have to carry a thumb drive in his pocket. There is no risk of mechanical injuries to the storage device as well. The data can be accessed from anywhere in the world and the user can work on any other computer if his own one is non-functional and in need of PC repairs.
Many of the online storage arrangements allow free storage of limited amounts of data and charge an annual or monthly fee for more storage. The computer can be programmed to back up data and store it at the site on a daily basis. Lots of computer users may not be aware of even such a provision, while others may not know how to program the computer for it. All these are arenas where a PC technician can help.
Another arena where a technician can help is in guiding the user to take advantage of the many inbuilt programs that a computer will have. Many users are either not aware of, or are not conversant with the programs. In short, a PC technician can help a computer owner in many more ways than doing PC repairs.
There are plenty of web hosting companies these days. Every webhosting firm promises many things, but when they have to deliver, some just fall by the side, and come a cropper. Therefore, it is advisable to be careful when you choose a web hosting company.
When you own a site and then get it hosted by a web hosting company, you are likely to entangle many web-hosting problems occasionally. Therefore, it is important that you find a good host, who has a viable customer support, and who will be able to provide you with onsite support and fix any existing problems. Always perform a little survey before you decide to choose a web-hosting company. Do not rush!
If you do a little browsing over the Internet, you will come across many webhosting services. Spend some time reading the sites, and search for some reviews about the site. It would be fantastic to read the reviews and know other’s opinions that have already used their services. At least you get a chance to know something about the company.
Make sure that the chosen firms provide customer support within a period. There are firms who will never fix any web host problems on time. Then, imagine how your business is likely to suffer in such cases. Apart from how the web hosting company provides customer support, you must also learn about the company’s experience. The more the company survives in the market, the more it has done reasonably well to be in the market. Finally, to say in short, experience is the key when you choose web hosting companies.
We all know the dangers of drinking coffee while typing on our laptops, but just like I’m doing right now, you probably drink coffee while working. Of course, once you spill your drink on your laptop panic and regret makes you swear the bad habit off, but until then our daily cup of poison must be drunk to get us going.
So what should you do if your laptop gets wet?
The first thing you should always do is to unplug it (if plugged), turn it off, and remove and external devices (e.g. USB sticks, mouse, external hard drive). Forget about backing up your files, because you just need to make sure you don’t fry your computer!
Next thing you do is to turn your laptop upside down (to prevent further seepage) and run for the most absorbent cloth or paper towels to wipe off as much of the fluids as you can. If your laptop’s keyboard easily comes off, take it off and try to dry off as much of the laptop as you can. After this, the best thing to do would be to take it to your service center. However, if your the DIY type of person then you can follow more steps to try to save your laptop from liquid damage, although it involves taking your laptop apart.
In case you already committed a big booboo by turning it back on when still wet and it does turn on or turns back off after turning on for a few seconds, then you’d better get ready to apply for a loan because chances are that you’ve shorted a vital part.
Testing your computer’s memory or RAM (Random Access Memory) to check is very important because it can cause multiple problems in your computer, such as repeatedly automatically rebooting. Testing it for errors will show you if it is time to get it replaced or if you need to check your computer for other possible causes.
The good news when it comes to testing your computer’s RAM is that it is as easy as pie. There are also free software, like Memtest 86+, that you can use to perform the test.
To use Memtest86+, all you need to do is to download a copy from their website, burn the file on a CD/DVD and run it on your computer. You will need to restart your computer and boot it from the CD to run the test. The test will do everything for you and will report any hardware problem. Of course, if it does find one then it’s off to the computer store for you to buy a replacement. There’s no need to sweat it because they’re quite affordable (compared to other computer parts, let alone an entire computer) so there won’t be a need to take out a loan just to get one.
Computer problems are greatly evident nowadays. There are those problems that can be readily fixed while there are those that seem to be very difficult to even just identify. For users’ easy and safe usage, there are now various ways on how to diagnose computer problems preventing further damage in the system. Checking newly installed software and running a virus or malware scan are just some of the most commonly used ways in diagnosing computer problems. There are cases the when the user installs new software, he or she is then asked for permission to allow changes brought by such installation. Sometimes, there are instances that problems arise after this is allowed. With this, users can diagnose problems through checking those newly downloaded software ensuring that it didn’t cause any problem. Another way of diagnosing computer problems is through running a malware or virus scan. Through such scan, problems are identified as well as its causes and so are its locations.
Users are always reminded of the importance of backing up one’s files. Behind this reminder is the fact that computers are always prone to system breakdown and nonetheless, users rarely see this coming. What causes system breakdown? The main reason behind it is user’s lack of knowledge. Indeed, the quality and functionality of a computer will only last if the user knows how to properly deal with its usage. Nowadays, though there is an increase in users, there as well seems to be an increase in unknowledgeable users that neglect the importance of maintenance. Just like any other forms of technology or device, computers are in need of regular maintenance to ensure that every part functions the way it should be but if for instance, there are already problems and are still taken for granted, the system can then just breakdown. Nonetheless, lack of knowledge of users leads them to incorrectly handling the said device which then causes more serious problems.
Computers are considered to be necessities in a person’s everyday activities. With this, it is helpful that the user has even that little idea on how to deal with possible arising problems on computers. Why is there a need to fix these computer problems? Once a problem is identified, it is almost always recommended that this is immediately considered and solved mainly to avoid it from worsening which could then lead to negatively affecting the parts and system of the computer. Nowadays, solving computer-related issues are very much attainable due to the rise of varying software that cater to such use and as well the increase in computer experts that find it really easy to find and apply appropriate solutions to visible problems. These issues and problem no matter how simple each appears to be must be taken into consideration to avoid more problems and of course, allowing more users to maximize the usage and benefits that computers are known for.
