Key loggers, in its most basic sense, is a software that logs or stores data of all details that are typed through your keyboard. Key loggers enable the computer owner to monitor the sites visited by the people who has used the PC. Also, passwords are detected by the key logger and stored to its database. The software also produces screenshots of the web sites that the users have visited. All of these data are then sent via e-mail to the person who is registered in the software.

For many people, the use of key loggers seems to be very intruding. Some view key loggers as intruders of privacy that no one can ever use the computer without giving data to the person who ‘supervises’ all the computer’s activity.

However, it is not always bad. Although it really seems unethical to encroach someone’s privacy, it depends on the purpose of the action that justifies it. Key loggers are extremely useful especially in keeping one’s family together. Key loggers detect web sites and passwords, which can be used to detect if one’s partner is cheating or not. It can also protect your children as you can detect earlier if your children are accessing sites with contents not suitable for their age group.

Like most useful software, key loggers come in with a price. However, it will not hurt someone, but would rather benefit someone, if one takes the initiative to look through the internet and shop around for other viable options.

Key loggers are very useful, but its use should be limited to personal use only. Putting this type of software in public computers encroach other people’s privacy. However, if you want to keep your family bonded together tightly, getting a good key logger program will be one beneficial choice to make.

Because of the rapid boom and advancement of the computer age, PC cleaners have already sprung into existence. However, since its “debut” in the computer market, the computer users are divided whether or not its usefulness pays off for its value.

Here is a little assessment of PC cleaners. Computer cleaners have the function of organizing the data on the computer and eventually “cleaning” it from “trash” or rather unnecessary and/or unwanted data inside someone’s computer. Its usefulness is simply awesome. At first, I doubted how it functions and how well it performs. But when I finally got one (I won’t say the brand as I do not plan to advertise with this), I installed it right away. It was quite surprising that such complex software was installed easily and quickly. The interface was user-friendly and even non-computer geniuses will be able to install it in a breeze.

After the installation, I automatically tested its functions. I commanded the program to scan and clean my whole system. In a few minutes, I got a result of the scan and the list of the data that have been cleaned by the computer. I was surprised by the load of garbage my computer has at that time. Temp files, internet cookies, history, and recycle bin items filled the list. The total data amounted to more than 3 gigabytes, in fact even nearing the 4 gigabyte line.

Imagine the weight that these trashes put on your computer and how it slows your unit down. But, I was happy and satisfied that I got my computer cleaned (and I get it cleaned again monthly) and I am enjoying the optimal performance that my computer should give me. Well, overall, PC cleaners are indeed useful and beneficial. Therefore, it is very much worth its price because of its intense usefulness for your computer.

I bet that all computer users and owners have already experienced screen freezes. Although in most cases freezes seem to be harmless, it is definitely annoying because you cannot do anything with your computer.

Why does this happen? The best possible answer is because of your Random Access Memory (RAM). For those who do not know what the function of RAM is, it is the capacity of your computer to multitask or to process multiple applications at one certain point in time. When the RAM overloads itself by having too many processes that the hardware can handle, the screen freezes because it cannot process data at its optimal speed.

Fixing the screen freeze is quite easy. Since your RAM is overloaded, basically, you have to unload your RAM. When the screen freezes, the best choice is to wait until the screen becomes active again. This is to not create unnecessary processes that will further slow your RAM down. If you can’t seem to wait or have waited long enough, press the start button (the button between your Ctrl and Alt in the keyboard OR you can click it with the mouse if the cursor still functions). The RAM would most likely set some space available for it as it would stop temporarily some background functions and processes to unfreeze the computer screen. If the screen is still frozen, then there is a chance that your computer has a virus that was able to penetrate through your antivirus. The possible solution for this will either be by rebooting your computer and getting an antivirus that could kill the culprit, or by formatting your PC to assure that it has been cleaned from any virus or harmful program.

When the computer screen encounters a freeze, don’t fret. Try the solutions above and fix the problem yourself.

Mozilla Firefox is indeed one of the most popular web browsers available, not to mention that it also one efficient and convenient software that enables us to surf the internet and even speed up our browsing which makes the whole experience worthwhile.

However, there are times when our trusty web browser encounters its problems and thus causing it to lag. With the lag of the browser, it then gets annoying because instead of speeding our internet surfing, it is slowed down.

Many of the computer users – or rather Firefox users – would ask, “Why does Firefox lag?” The answer is simple. Most likely there are other data present that weighs down Firefox. A computer (even software) can be compared to a hiker. The hiker is loaded up with things necessary for his hike and paces at his natural, optimal speed. But if you would add up things to his baggage that are unnecessary, the hiker’s pace will surely slow down. The same goes with Firefox. Here are some solutions to the major problem of lag:

• Clean Firefox – Yes, software can be cleaned. In the case of Firefox, you can clean it by clearing the cache, deleting the history, and removing the unnecessary temporary internet files. Remember, more junk is more lag.
• Clean the Registry – It is highly vital for you to clean up the registry of your computer. More junk is more lag. Firefox creates a lot of data on your registry, thus loading the software up and slowing down its process.
• Manage Your Add-ons – Many Firefox users fail to manage their add-ons well. Add-ons like plug-ins and toolbars can weigh your browser down. It is best that you disable or even uninstall plug-ins and/or toolbars that are unnecessary. Doing so will lighten Firefox’s load and will give you a better performance.

PDF files are very widespread nowadays, and majority of important documents (that do not have to be edited) are stored in this type of format. But, the usual problem with these files is when we need to modify some of its contents. We can’t do it in the Reader, so we’d find a way to convert it and make it editable.

The usual way of converting PDF to an editable version is by converting it to Word (.doc or .docx). Doing this usually requires you to download software that has the capability to convert PDF to Word. One of the most common in this is Adobe. However, there are also other programs that are coded to do the particular type of job.

There is another way though. As downloading software and installing it is not always possible, there is another way of doing so through the use of the internet. There are already websites that cater their services of converting files to other file format, PDF to Word for example. It is not limited to that type of job though. Some websites can actually convert ODTs to PowerPoint files. The staff of the website can help you in converting it and some sites usually require payment for the conversion. It may seem a little too much for paying but if it will save your document and ready it when you need it, it will be quite a good deal.

There are also free sites that convert PDFs. These sites may be sometimes good, depending on the site you visit. However, it does not guarantee accuracy of the conversion. Some words may be misaligned and such. Grammatical and typographical errors may also arise. For people who just want their PDF converted, this is good. But if you need formal files, then the pay sites will be better.

Windows 7 is the latest upgrade of Microsoft to their operating system line. Maybe you want to upgrade to it because it is said to be better than Vista (because comparatively, Windows 7 runs on lower resources than Vista). However, not because it is better means you are obliged to upgrade to it right away. First, ponder upon these points before you upgrade your operating system:

1. Hardware – Your computer hardware matters. Not because you can run your computer on XP means you can run 7 that easily. Yes, you may install it, but have you considered the possible performance it may bring? Barely meeting the minimum requirements means a very slow Windows 7. Your hardware should be able to pull it off with a better performance with better computer components. Also, if you plan to change your computer in a year or two, it would be better to postpone upgrading your OS. It would be more practical to buy a new computer (with better specifications) with a pre-installed Windows 7 operating system. Not only should you check the components of your CPU, but also other third-party hardware (i.e. webcam, printer, scanner, etc.) because some hardware do not support Windows 7; thus, rendering your third-party hardware useless. Consider these things first.
2. Software – Even if your hardware is enough to run a well-performing Windows 7, if your software lacks the compatibility to Windows 7, then it will be a hassle. Of course you have installed different programs in your computer (perhaps in XP or Vista), but the question is that will it work with Windows 7? Not all software has later versions that can run on Windows 7.

These two things are primarily the things you would have to consider before getting Windows 7. Be sure you check on these or else it could be a setback.

Sound cards are in form of chips which are integrated on the motherboard of your computer system. This integrated chip helps in obtaining audio output from your system enabling to accomplish various sound based tasks. Since, the sound card is a crucial component which completes the functionality of a computer system, it is essential to pick the right kind of sound card or audio card for your computer. For your assistance, the following article will focus on important aspects that will help you obtain a practical and suitable sound or audio card.

Interface or Technology:

While buying any computer component, it is essential to ensure that the computer component is compatible with the system. Hence, considering the interface or the technology on which the component is designed can help you obtain a simpatico part run with your system. Similarly, while buying a sound card it is essential to match the technology or interface with that of you system’s motherboard. There are two common types of technology which serves as the base of most sound cards that are available in the market today namely ISA and PCI.

ISA: ISA cards are cards which were initially introduced and are older technology as compared to PCI technology. ISA is the abbreviation of Industry Standard Architecture and was released in the year 1981 by IBM. Sound Cards based on ISA technology are mostly cheaper now and are not so popular. People who have systems working on ISA technology purchase these ISA sound cards.

PCI: PCI or Peripheral Component Interface sound cards are advanced cards which are widely seen in market today. Since, most computer systems utilize PCI sound card technology, most people with latest computer look for PCI interface. This technology was introduced in the 1993 by Intel. Most motherboards nowadays have PCI slots which serve as a standard connectivity option for sound cards. The reason why PCI slots are competent as compared with ISA slots is that PCI can handle 64 bit of data whereas ISA can only handle half of it which is 32 bit data.  

While purchasing a sound card, it is essential to check whether your computer motherboard already has a compatible sound implanted. There are fair chances that you may get a sound card already installed on your motherboard, if not then you may have to buy a compatible sound card for your system. These types of sound card are also called as “on-board sound card”.

Once you have determined what type of soundcard will be suitable for your motherboard you need to determine other features of your sound which are also decisive factors while buying a sound card.

• Speaker connections: It is essential to determine whether speaker connections offered through the sound cards are sufficient for your use. Most people using more than one set of speakers may require extra S/PDIF ports. Sound cards usually have different ports serving different purposes. Usually the use of the ports are indicated in colors for example pink colored SPDIF port would generally be used for Microphone Input, a black colored port would connect to a Subwoofer/ Center where as a green colored port would serve the headphone or Front Speakers Left and Right. Likewise there are other ports with different color codes used for different functions. Hence, you should determine the nature of your use and select a spound card with sufficient ports for connection.
• Available Midi Port: Sound cards also provide a specialized port for gamming purpose technically known as Midi Port and commonly referred to as Game Port. This game port can be an integrated as post 1990 almost all computers have game port already installed. It can be based on either of the technology PCI or ISA.
• Microphone Connection: Usually all sound cards come with SPDIF port for Microphone connection. As mentioned early, port for mic will generally be in pink color, depending upon the manufacturer. You need not by any additional hardware to connect your mic.
• Full Duplex: As computers are nowadays used for online voice chat purposes it is essential for the computer sound card to support Full Duplex technology. This technology allows the devices to play as well as record sound at the same time. It is helpful for competently communicating over internet using VoIP. 
• 3-D acceleration in sound: 3-D acceleration is very useful for games and is available in three types namely DirectSound 3D, EAX and A3D. Hence while buying a soundcard it is essential to ask about 3D acceleration.
• Cost: Cost is something that most people would give the first preference when it comes to buying computer products. The cost of a Sound card may evidently vary on different factor such as manufacturer, technology used and features offered. However, an average soundcard will cost you around $200 to $300.

Some other consideration:

Warranty: Warranty is something that one should always consider when buying any commodity especially when it comes to electronic goods. This will help you save the money which you would have otherwise spent in repairing the component when it stops functioning. This is because when your device is under warranty then you are eligible for free or economical service based on the conditions.

Customer support: Most people wisely consider customer support when they buy sound cards. It is evident that electronic good are more prone to technical malfunctions; for assistance on basic troubleshooting which can be accomplished on phone you would require a customer support number which may help you rectify common issues. However, you should determine whether the company offers round the clock customer support for all seven days a week also ask whether the number they offer is toll free or premium based.

Make sure you buy a branded sound card from an authorized dealer who is well established in the industry. There are some dealers who also install the sound card for you on your system. However, if you are trying install the sound card on your own then it is essential to take experts assistance while accomplish the task. For assistance on installation of sound card you can refer to our Sound Card Installation Guide

Video card are also referred to as Graphic accelerators and graphic cards. It is also some time called as video adapter and display adapter. It is an important internal chip of a computer as it helps the users to obtain graphical presentation of the data he is working on. It also helps in watching movies, playing games and other tasks which include visual intervention. Most work which includes videos flash etc may be almost impossible to accomplish if graphic card does not exist in computer system. Hence, it is a crucial component which should be selected carefully. This rest of the article will throw some light in things you should consider while buying a video card.

Type of card: One of the crucial and decisive factors that should be considered is the type of card that will suit your motherboard. It is essential to determine which video card will suit your system when it comes to upgrading or installing a new graphic card in your system. Remember that when you upgrade your video card, make sure that you buy the next best version of your existing graphic card. You cannot skip a level and get the third level advanced graphic card as it may not be compatible with your system. In order to get information on how to determine the configuration of your card you can check our Determine Existing Video Card/ Graphic Card on Your Computer. You should also make sure that you buy a compatible video card for your system.

Connection types: There are three standard different types of connectivity option which can help you connect your graphic adapter to your system. Compatibility factor also comes into consideration in this phenomenon.       

PCI-E: PCI-E can be considered as an extension card interface which is also referred to as PCI-Express. This interface is used to link extension cards such as Video Card with the system motherboard. PCI-E was introduced as a successor of PCI, AGP and PCI-X standard interface. The PCI-E was introduced in July 2002 and is the newest technology connection bus used nowadays. This interface is available in different formats name X1, X2, X4, X8, X16 as well as X32. You should have relevant port on the motherboard to connect through PCI-E cable.

AGP: AGP is the abbreviated form of Accelerated Graphics Port, which an interface which was used with Intel Pentium II computer for connecting graphic cards. This standard of interface was introduced in 1997. It is a 32 bit cable which is capable of working with highly advanced video cards. Unlike sharing PCI bus, APG has dedicated route between processor and slot.

PCI: PCI is the abbreviation of Peripheral Component Interconnect which was introduced in the year 1992 by Intel. It was designed to work with 32 or 64 bit bus. It is said that PCI allows data transfer rate of up to 132 MB per second at clock speed of 33 Megahertz. However, it is said that instead of PCE slot AGP slot shall be used. In any case you should determine whether the interface you are adopting is compatible with your system.

Power Supply: Video cards nowadays are built on advanced technology due to which they require high power. Hence, while buying a graphic card you should determine whether you power supply will provide sufficient power to the video card. Most contemporary video cards may require 500 W or even more. If you learn that you power supply will not meet the requirement then you can either upgrade your power supply or go for a lower version of graphic cards. To determine the configuration of your power supply you can check the label on your PSU or SMPS. Sometimes the model number may also contain the wattage of the device.

Memory: A crucial factor that should be kept in mind while purchasing a video card is the video memory that the card offers. Similar to system memory, these graphic cards also holds some memory space. The more is the memory of your card the better is the performance and quality of video. A computer should have a video card with minimum 256 MB of video space.

Ports: Most of the latest graphic cards have DVI ports. However, there are fair chances that you may come across cards which enjoy both DVI as well as VGA connectivity option. If you have a card with VGA connectivity, then by using a DVI to VGA converter one can accomplish the task.

Chipset: Chipset is another important factor that serves as a decisive factor to determine which video card will suit you the best. You may come across numerous graphic card brands but there are only two major chipset manufacturing companies namely Nvidia and ATI. Both companies offer competent chipset to suit your graphic card and their competency may differ extensively. Hence, even before you buy a video card you should check which chipset performs optimally and based on that buy a compatible video card for better performance.

Size of the card: Computer chassis or computer cabinets are available in different sizes and shapes. Hence, in order to make your graphic card snugly fit into the cabinet you should consider the size factor. Due to advanced features and enhanced competency the size of video cards have increased therefore it is essential ensure that your cabinet offers sufficient space to accommodate graphic card. You will have to physically look into the computer and check whether the graphic card will fit into the computer chassis.

Cost: Cost is another significant consideration which should be kept on mind while you buy your video card. Inevitably, the price range of video cards may vary according to various factors such as manufacturer, technology used etc; however, a conventional video with considerable feature will cost you between $100 and $500. 

Warranty: Similar to other factors warranty also plays an important role when it comes to buying video cards. This proves to be helpful when your device is corrupt or suffers from any technical malfunction. Under such scenarios if your graphic cards in under warranty then you have to option of getting it repaired by experts from the company itself, without having to pay any amount of money.

Support: Also try to find out information on customer support facilities offered by the company. This will help in case there is are any small issues which can be solved over the phone by following simple troubleshooting steps. This is will eradicate the need of physically sending the device to the company and waiting for a long to receive it back. While you consider asking about customer support you need to make sure that they proffer 24 x7 customer support facilities.
