Why Does My Computer Keep Freezing Up? – How to Fix PC Lockup Problem?

"Why does my computer keep freezing up?" I was asked by a lot of people the cause of their pc free problems. And I am fed up with spending much time in answering the question time and time again. This article is to tell you the real cause of your PC Freezes.

Many people think it is the low RAM resource that results in the lockup problem. So they upgrade their RAM to 2 G, 4 G or even higher. But unfortunately only a few people successfully resolve the problem. Why? Because the shortage of RAM is only one of the possible causes that lead to only approximately 20% of the PC lockup / freeze problems.

The most probable cause of your trouble is the system problem – Registry Errors! That is the reason why people who already have more than 2 G RAM on their computers are still constantly bothered by the problem.

What is registry? It is the system database in which your most important system information and program settings are saved. It contains all the vital directive information for your Windows system. Your system needs to access the data in registry before it can execute a certain operation and process like system shutdown, restart, running a program, opening a file and so on.

But registry is easily corrupted and damaged when you are using your computer. Overtime, without proper maintenance, it will be loaded with errors and incorrect or even missing information which will make your system unable to work properly or implement a certain task. And when your system can not find the correct information, it will not know what to do. Then it freezes up! That is the real cause of your trouble.

How to fix the registry errors and stop your computer from freezing? You can download a good registry cleaner and install it on your computer. Then run a thorough scan in your registry. Your trouble will go away. And keep in mind that registry is easily damaged. You need to clean it up by running the registry cleaner once or twice a month at least, or you will have the problem again.

The Relationship Between Science, Technology, and Society

Science and technology is the best thing society could ever ask for. Since the industrial revolution in the 18th century science has been in progress. Some sectors that have been boosted by science and technology are energy, physical sciences, information and communication. The society has greatly gained with the invention of technology.

Infrastructure in the society has grown with the help of science and technology. Modes of transport like electronic railway lines were realized and these actually benefited the society by offering them a better means of transport. In the past, almost everything was analog but thanks to the science and technology we are now being digitalized by the day. The invention of the telephone and radio services has broadened human communication.

Without society then there would be no science and technology and that is why the invention of certain tools and equipment have helped achieve big things. Society can not do without the industries we have today. The society needs science and technology. The creation of computers is work of art by individuals was a milestone that would come a long way in helping the society. A computer helps us to leverage ourselves by gaining valuable information that we can use to enrich our lives. The impact of science and technology can seriously be recognized. Many people around the world take for example scholars in colleges and universities have taken the lead examining the relationship between science and technology.

The evaluation of this relationship has emerged as an important area of research. Public interest groups and academic organizations throughout the world are recognizing the importance of STS. The reason is that people need to recognize that there are people who are affected by the science and technology. Controversies such as modified foods, stem cell research are the issues that have brought policy makers and scientists together to have a way forward on this.

Science and technology has actually largely contributed to the vision of man about himself. Science has been modified the opinion about the origin of man and place of origin too. Through the results of scientific discoveries the perception of man about his behavior and his place of origin has been modified diversly. Experiments in science today are in one way or another affecting the society.Take for example the experiment on cloning a human being. The experiment brought a lot of controversy since the society was skeptical about it.

How is science and technology related to society: The developing world has a long tradition of participatory action research, popular education and community organization joining up to solve some science and technology issues that affect the society. How is science and technology related to the society is something that is calling even for the government intervention. Science and technology related issues are actually been discussed worldwide today. Progress in this has resulted to the ability to produce diverse types of material items. Answering the question how science and technology is related to society.

Computers play a big part of our everyday life. You can find a computer in almost every home in America, not only for entertainment purposes, but also for educational purposes.

School departments across the country have recognized the value of adding computers to classes and in many schools there are computer stations where children can complete their assignments.

Teachers can program the computers in their classroom with learning activities that children will enjoy playing, without realizing that they are actually learning.

Most households have working parents, when they come home from work; they have household chores such as laundry, preparing dinner, clean up. There is very little time to supervise or even help with homework.

In families that have single parents, time is even more constricted. This is where a computer can assist the parents by assisting the child with their homework.

There are some drawbacks to a child learning from a computer, but the benefits far outweigh the drawbacks.

Strategic and analytical skills can be learned a lot faster on a computer then in a conventional classroom. Software has been developed in age appropriate levels to help the child identify numbers shapes and colors.

Parents and teachers can download or install software to give the child the resources he or she needs to complete any assignment. The child is taught how to turn the computer on, and how to operate it; he or she will have access to a wealth of information.

Games are not only for entertainment purposes. They can teach a child how to think about how to overcome an obstacle and solve a puzzle. It is strategic thinking that they can carry into their adult lives.

It is recommended that parents choose carefully the games and programs that they download. It should be something age appropriate to avoid the child getting frustrated and give up. A child needs something that is challenging, but not impossible to complete. The Internet offers millions of downloadable games and activities for children of all ages. It is important that the parent screens the games before their child or children use them.

Allowed older children to pick the subjects and activities that interest them. If they enjoy science, then download a program that he or she can do a science project on the computer. If you have a mathematically genius, then download math projects. It can be fascinating for a child and they are learning at the same time.

If you want to spend more time with your child, you can make computer time quality time spent with your child. Sit with them when they are at the computer and encourage them, when they complete an area of ​​the program praise them.

If you can replace television time with computer time, you are not only assisting them with their education, you are creating fun filled family time that your children will really respond to.

Top Reasons to Love PC Games

Most of the kids love to play PC games. Not only the kids even some of the adults love them too. It should be noted that the games that are liked by these entertainment loving players are not always an easy option to play. Most of them are quite difficult. But as I mentioned earlier that we are all lovers of the games so do we master its tricks soon with focused playing. Now, coming to the devices that are used to play games we can say that there are mainly two types of gaming. One is the gaming consoles and the other one is the PC games.

While consoles are new and can be easily carried everywhere but the game lovers claim that the PC games offer better gaming experiences. Reasons that attract gamers to play games on the PC are described underneath.

Availability of Different Types of Games

In the PC, one can get to play a number of games. This is because PC has several features which provide the necessary environment for installing and playing the games. Most of the games are free to download, but, if you are using the consoles then you have to pay for each and every games you install in them or want to upgrade. So, you can install any games from the adventures games to the games that kids like to play.

Better Gaming Experience

With PC, you get the opportunity to play with the gaming keyboards, joysticks, etc. The consoles never offer such choices. It has limited keys and overuse of them can cause them to damage. They also do not offer immersive sound quality like the PC does. And when someone else is around then they can use headsets to enjoy the sounds. You can also challenge you peers over the net and call them to compete with you over PC. The consoles have limited number of games that offers these facilities.

Longer Life of the Devices

Consoles last for a maximum of 3 years. It might be less but not more while a personal computer lasts for several years. You actually do not have to get them upgraded frequently because newer versions if at all comes need not be installed necessarily.

So, you can see that everything about the PC games is good and easy. Undoubtedly, for the same reasons, PC games have become the easy choice of the numerous players around the world.

The Broad Categories of Computer Networking

For some people, the computer itself could be a scary topic, considering the fact around how complicated the machine is. Talking about computer networking could give a heart attack to such people. However, it is not as scary as it may sound.

Computer networking could be understood by separating the two words in the term. A “computer” as we know is a complex machine that helps us to process information. “Networking” refers to linking or connecting. Hence computer networking would simply mean getting two or more computers connected. When we say the word “connected” in this reference, we mean that one computer could be accessed through the other.

Broadly speaking there are two ways of connecting two or more computers. The first one is called the wired network and the other one is called the wireless network. Both of these are huge subjects to study and understand. However, in layman’s language it could be said that when two or more computers are connected through wires it’s called the wired network. And when they are connected without the wires through wireless router, it is known as wireless network. As the wired networks are limited to the area wherein the wire web is installed, similarly the wireless has range limitations. The number of machines that are on a network would ensure the speed of the network. More machines in a network would mean a slow network.

The various computer network systems could be – Personal Area Network; Local Area Network; Campus Area Network; Metropolitan Area Network; Wide Area Network; Global Network and most importantly internet, intranet or the extranet. The names are given to the network depending upon the arena they have. Like for example the campus area would mean the machines that are in a given physically limited campus are connected through the computer networking. This could be wired or wireless networking.

Internet could be understood as a global network system.

Computer Game on Mars; Design for Communication Device

As the pictures from the Mars Rover and the Mars Satellites come back in greater detail we will begin to see computer video games, which will have the Martian Surface as their backdrop. These computer video games are becoming more and more defined and realistic. NASA themselves have put together virtual reality and augmented reality settings to train astronauts and the CAVE Institute has also been gathered data sets and digital pictures and video to make VR Mars experiences a reality here on Earth. Currently there are over 1.6 million digital high quality pictures of the Martian Surface which have been beamed back to Earth and this is enough to make a super Xbox 360 experience for you in your own living room your new Plasma High Definition TV.

One of the challenges now to go with that backdrop is to design realistic components, space surface vehicles astronaut suits, space habitats and devices, such as hand held communication devices that the video game characters will use. Now then this will take a little extra thought, as it is important for video programmers to stay ahead of the game. First off these astronauts will not be holding in their hands anything looking as silly as a cellular phone. Chances are they will communicate via devices on their neck which will sense the vibrational movements of their vocal cords and send them via voice activated sound or directly to a device in their fellow astronauts ear or a tiny microchip inside the ear near the ear bones, which will run off the electromagnetic induction of a miniaturized unit catching pulse and brain waves to power it up. So to be realistic as a gamming programmer you need to be thinking here.

Top Ten Things To Consider When Buying A Computer

When entering into the world of computers it can get very easy to get confused and loose sight of your goals and sometimes your budget. Hopefully I can help you set some realistic goals and make sure you get the computer you really want and need.

1. The first thing that most of us are constrained to is budget so this is the first thing you should consider. We always want the best but we need to be grounded on what we can afford. So Get a budget and stick to it.

2. The next thing you should be looking at is your requirements. Do you need a laptop or desktop? What is the machine going to be used for? Once you have done this go back to number one and see if these are compatible often they are not first time round. You either need to adjust your budget or adjust your goals to make them more compatible with each other.

3. Once you have ironed out the bugs it's time to move onto the computer itself. There are many things to consider when actually buying the computer, here I will list the most important so you can choose wisely.

4. The Processor is the most important factor when choosing a computer nowdays and there are many factors in processor choice the main thing is that in my opinion Intel are at the moment making the best chips and their core 2 duo range is the best so go for one in this family and you will be ok.

5. Next it is on to RAM, now this is simple for most just go for as much as possible and remember if you go above 2 GB then you must make sure you get windows vista 64bit as your operating system.

6. Hard drive is the next piece you should tackle. Again for the ordinary person it should be just a case of bigger is better.

7. Graphics, now all computers come with some form of graphics built in. But my recommendation is to go with something a little better possibly from NVIDIA.

8. Now that should be your main considerations when thinking of the hardware. The next thing to think about is software now many computers come with windows vista as standard, this should be premium at least I would not even think about basic.

9. The last thing to do with the actual computer is a good virus and spy ware package. Do not be under any illusion This is probably the most important part of protecting your computer. It will get attacked at some point be prepared when it does.

10. Finally the internet, get a good internet provider broadband at least, no computer I complete without this basic of add-ons.

I hope this list is helpful in helping you make vital decisions when buying your new computer.

Will Magic Trackpads Turn Computer Mice Into Antiques?

Apple Computer systems has created an item they're calling a "Magic Trackpad" and business speculation is buzzing that Apple is hopeful of the Magic Trackpad perfectly replacing the standard mouse as the technique by which users move the cursor around the screen on their computer systems .

Numerous laptop computer systems, regardless of whether from Apple Computer systems or from manufacturers of Windows based machines, have had trackpads obtainable for many years. There are even windows machines that allowed an external trackpad to become attached to a desktop machine instead of a mouse. Users who advocate for the trackpad have discovered it simpler to utilize than the mouse and have discovered it leaves them far less susceptible to repetitive tension injuries.

Now, if Apple is hopeful of extremely replacing the mouse with the Magic Trackpad, it's doubtful that the mouse will turn out to be an antique like an antique Persian rug. Unlike vintage rugs, a mouse based on old technologies will almost certainly not have much purpose going forward other than a curiosity piece, or a museum piece somewhere like the Boston PC Museum.

In order for Apple to have invested in the development of the Magic Trackpad, they would have to become convinced there is really a marketplace for them. So they've almost certainly received thousands if not millions of phone calls over the many years requesting a trackpad kind of function for desktop machines. Individuals who had worried about utilizing the mouse simply because of repetitive tension or had just gotten tired of the mouse, almost certainly decided the trackpad was the technology that most fit their requirements, and asked Apple to develop one. Earlier Apple laptops had utilized trackballs and almost certainly some folks felt the trackball was nearly as unwieldy to utilize as the mouse but the trackpad enabled the user to utilize one or two fingers from either hand.

Will the Magic Trackpad really be able to fully replace the mouse for all users? Most probably not, as there are many people these days who attach a mouse to a laptop with a trackpad simply because they are more comfortable utilizing the technological tool they very first learned. You will find people who will choose the trackball. But Apple obviously does not see the marketplace since they have created the item. As numerous business analysts have noted, Steve Jobs has a fairly great track record on item development, even if there is not a ready marketplace identified, and if Apple has received sufficient requests for trackpad technologies over than the many years, the marketplace has already been identified.

Will the mouse turn out to be an antique? Possibly, but almost certainly not as valuable as the antique Persian Rug.

Computer Speedup Tutorial – A Trick to Make Any PC Run Like New

One of the largest issues facing computers today is the way in which they are rather running slowly. This problem is a huge issue for millions of systems around the World, and is caused by a large number of potential problems that can develop on any Windows system. Although there are a few effective ways to speed up your PC again – there is one really powerful "trick" you can use to boost the speed of your system back to the levels it was at when it was new.

The way to speed up a PC is to fix the problems that cause it to run slowly. Many people make the mistake of just trying to tweak and optimize their system to improve its speed, but are unaware that unless you have a strong "foundation" for your system, you will not be able to improve the speed of your PC at all . There are a number of reasons why computers can run slow, but there's one main cause which is extremely easy to fix and could make your PC run like new – by cleaning out the registry .

The registry is a central database inside your computer which stores a large number of files and settings that Windows requires to run. Everything that Windows requires to run are kept inside the registry database, making it one of the most important & frequently used parts of your system. Settings such as desktop icons and even your stored website passwords are kept in this part of Windows, making it one of the most important features of the Windows system. Unfortunately, the registry is so important that it's used too much, causing your computer to save many parts of it in the wrong way, leading it to run slower and with a lot of errors.

The registry database is the most common reason why Windows will run slow – and now many people even know it exists. It's also why computers tend to get slower with age – because new PCs have no damaged registry settings to hold them back. This is a huge problem because it causes Windows to be unable to read the files it requires to run, making your system run slower and slower as it tries to decode the files it needs. To fix this part of your system, you can use a software program called a 'registry cleaner' to fix all the potentially damaged settings inside it.

Computer Freezes? An Effective Method to Stop Computer Freezing

Like blue screen and blank screen, computer freezing is an annoying problem to Windows XP, Vista users. I researched for a long time for the reason why computer kept freezing. Finally, when I found it, I was in big surprise!

It was Windows registry which caused computer freezing!

The Windows Registry is a database that stores settings and information for hardware, operating system software, and non-operating system software. That is, registry contains vital information of PC device drivers and all installed software.

When you run a program, registry provide the information of the program to Windows. Then Windows can find the location of the program and access the settings correctly. With the information, Windows can run the program smoothly and stably.

Registry is usually saved as DAT, SAV and other files, spreads over the system disk where you installed Windows. Registry key is the smallest unit which store the value of specific programs. It is very vulnerable.

If you install and uninstall programs from computer, registry keys can be easily damaged. And if computer is infected with virus, malware, spyware, they can also bring damages to registry keys or even delete some keys completely. These two issues result in up to 90% missing, invalid and corrupted registry keys.

When some keys are damaged, the programs and drivers will not be able to work properly. That is why you frequently have program not responding, screen freezing, blue screen and blank screen of death. To solve those problems, you need to clean up and optimize registry regularly.

Computer Repair – Peak Performance Is Important

Computers are a part of daily life, both personal and professional. If your computer was to encounter a problem your life could have been seriously hurt. It does not matter if it is a hardware problem, software problem, or a spyware or virus infection – a broken computer stinks! Since computers are complex pieces of machinery most people will seek out professional help when it comes to computer repair.

Computer problems can be hardware related. This means that a mechanical part of the computer fails. Most individuals do not have the expertise needed to perform this type of computer repair themselves. Expert help is usually thought for problems like hard drive failure, motherboard failure, or CD / DVD drive failures.

Virus and spyware infections are potentially serious issues that must be addressed. Most everyone runs some form of virus protection or spyware protection on their computers. However, if the programs are not set up to date a virus or spyware infection can pass through the program. Even if you keep your virus protection current new viruses are being created all the time. You might have had the unfortunate luck of going to a website that harbored this new virus before your anti-virus software was updated to include the new signature files. There are free tools on the internet that allow a person to attempt to remove the virus or spyware on his or her own. Some of these malware programs are so bad that the services of an expert in computer repair need to be obtained to restore the computer to a virus free status.

Software problems are also a reason a person would bring his or her computer to be repaired. Files can be corrupted, and this can cause a program to operate in strange ways. Again, a person can try to repair the problem on his or her own, but more often than not the computer is brought to an expert for repair.

When thinking about computer repair you might only think about it in terms of a problem with your PC. However, preventative maintenance and computer upgrades fall under the category of computer repair. Replacing an aging video card, adding additional RAM to your computer, or upgrading a hard drive to a solid state drive are all things that you can do to make your computer run better. You are not bringing it to an expert when it is "sick" but you are taking it for a "well visit" to make sure it runs as well as the day you bought it home from the store.

A computer that is working at peak performance is important. If you have a PC that is not working the way it should then computer repair is necessary. If you have a PC that is running satisfactorily, but you would like to see perform better, then computer upgrading services performed by a repair professional could be just what the doctor ordered.

Desktop Computer – Know It Better

Desktop computers, a type of micro computer, fit on a desktop and are used broadly in offices and home. Personal computers or home computers, workstations, internet servers and special communications computers are four types of desktop computers used. Desktop computers are widely used in household, schools, business as these computers are very cheap.

The desktop computers are typically modular and its components can be easily upgraded or replaced. These are available in elegant case styles. They are used for carrying various tasks like organizing digital photos, office tasks, editing of video and accessing Internet.

Micro Instrumentation Telemetry System (MITS) 8800 introduced the first desktop type system in 1975. The launch of this variety of computer illustrated scores of other companies to produce personal computers. In 1977, Tandy Corporation (Radio Shack) launched its model of personal computers having a keyboard and CRT. In the same year the Commodore PET and Apple II were also released market and these are forerunners of today`s Desktop computers.

Introduction of IBM PC, in 1981 by IBM, was a milestone in the field of Personal Computer. Based on Intel`s 8088 microprocessor, it became a success overnight. The introduction of a 16 bit microprocessor paved way for more powerful and faster micros. Also standardization in computer industry could be made as IBM PC used an operating system which was available to all the computer manufacturers. Apple Mac PC using Motorola 68000 is another series of 32 bit popular personal computers launched by Apple in 1984.

A modern desktop computer consists of Display Motherboard, CPU, Primary storage (RAM), Expansion cards, Power supply, Optical disc drive, Secondary Storage (HDD), Keyboard, Mouse.

All the desktop computers come with ports which allow plugging different external devices into the computer viz, keyboards, monitors, scanners, printers.The different type of ports are Universal serial bus, Ethernet, Modem, Headphone, Serial, Parallel, PS / 2, VGA, Power connection, Fire wire, and Card reader.

You should surf the internet to check for detail guides available before purchasing a desktop computer. A few important points are listed here which may help you to have an informed purchasing decision:

Processors (CPUs): It is a very difficult choice to make between an Intel processor and an AMD. The main difference comes in the relative speed and number of cores in the processor. You should refer for the detail information on this in the internet sites.

Memory (RAM): It is best to have at least 1 GB memory system and older DDR memory standard should be avoided. For better performance, faster memories are required and ensure that future upgrades of memory are possible.

Hard Drives: 250 GB or more storage space is best to have in present days. Serial ATA interface is used in most drives now for ease of installation.

Optical Drives (CD / DVD): Multiformat DVD burner which can support both + R / RW and -R / RW with a 16x recordable speed are best to have in desktop computers.

Video Cards: Integrated graphics is sufficient if you are not doing 3D graphics. The important things which you should consider are the memory capacity of the card, version of Direct X supported, output connectors and the performance. For the purpose of games a Direct x 10 card with 256 MB memory should be considered.

External Connectors: Instead of internal cards, external interfaces are preferred now for various upgrades and peripherals to computers. IEEE 1394 or FireWire points and USB 2.0, both should be present in a desktop computer.

Monitors: These days LCDs are more popular than CRTs. This is because they have less power consumption and have reduced size. Also traditional aspect ratio of 4: 3 is being replaced by wider display screen and prices of 20-22 inch models are decreasing.

Computer Lap Desks

Laptop computers were designed to make life easier by allowing the user to carry them around all the time and work anywhere at anytime. Though this is a godsend, laptop computers have a major drawback.

The portability of these machines may be their strength, but they are designed in such a way that the user has to adopt an array of uncomfortable positions to work on it. The lack of proper screen height or proper keyboard angles means that laptop users are oftentimes required to crane their necks or strain their wrists unnecessarily. Needless to say, constant crating of the neck, training of the wrists or sitting in bad positions can take its toll on the health of the user.

Computer lap desks are provided to relieve laptop users of the need to use these uncomfortable postures. Many computer lap desks come with features that include adjustable angles and heights. This allows the user to adjust the position of the laptop to suit a position, resulting in greater levels of comfort. When lying down, the lap desk can be adjusted so that the screen is elevated and the keyboard tilted forward, so that the neck, wrists and back are not unduly strained.

Computer lap desks are available in a variety of styles, looks and designs – each having its own unique features. There are some lap desks that come with a tapered pillow and large surface areas coupled with mouse friendly surfaces. Many lap desks are made from durable materials such as canvas, plastic, wood, aluminum and foam pillow. Most lap desks also have undersides that are rubberized to prevent the desk from slipping off of your lap. Dual risers are also provided to elevate the laptop and allow the computer's cooling fans to work property, thereby preventing the computer, as well as the user's lap, from getting uncomfortably warm.

Gaming Hardware Guide – Learn What It Takes To Make A Gaming Computer

So you're into gaming, and you're looking to turn that shabby computer into a gaming powerhouse? You do not need unnecessarily expensive gaming computer though, you just need some decent gaming hardware.

If you do not exactly know what gaming hardware is, I've put together a guide explaining what it takes to have a gaming computer. You do not needily need all of these components, so I've broken them down by level of importance.

3D Video Card

First and foremost, if you have to have a decent video card to play the latest 3D games. You can have the best computer around, but if it has a cheap video card, 3D games will appear to run as slow as if you had a slow computer. You do not necessarily need the latest video card, because at the rate they come out it will be outdated in a few months anyway .. unless of course you have $ 500 burning a hole in your pocket and you really want to.


Since your CPU is the heart of the computer, this one is kind of obvious. Like most things, you do not need the fastest CPU around, but if you want a real gaming computer, you'll want something at or around 3 gigahertz (or 3000+ for you AMD enthusiasts).

You'll also want something that has a fast front side bus. It's usually best to find a motherboard and cpu that have similar front side bus speeds, because they work together, and the overall speed of the front side bus will only be as fast as the one with the slowest speed on it. It's kind of like driving a sports car on a highway with a 55 mile per hour speed limit, the car might be able to go 155, but the highway will only let you go 55.


Also known as Ram, it's what applications and games use to store information, the more the better. It's good to have at least 512 Megabytes, but real gamers have 750 megabytes, to 1 Gigabyte or more. Memory is extremely cheap these days, it's one of the cheapest and simplest upgrades you can do.

It's not only the amount that matters though, they also come in different times. DDR2 is the fastest, cheapest memory you can get right now. If you have SDRam, you'll probably want to upgrade your motherboard and CPU so you can have faster memory. It's kind of drastic, but your games will most likely be sluggish if your equipment is that old. Regular DDR is good enough for gaming, it just does not have the throughput that DDR2 does.


Today's fastest motherboards have faster Front Side Bus. The Front Side Bus (or FSB) is essentially the highway that runs from the CPU to the Ram, the bigger the highway, the more traffic it can handle at once, making calculations faster. Another thing to watch out for is what kinds of hard drives it supports. If you want SATA or SCSI drives, either your motherboard needs to support them, or you need to purchase an expansion card to plug them into. You'll also want a motherboard that supports the fastest computer memory you can get, which is currently DDR2.

Hard Drives

Hard drive speed may not sound important, but it can be one of many bottle necks that your computer runs into if it's not up to par with the rest of your computer. If you purchase regular IDE hard drives, you'll want at least 7200 rpm (rpm = rotations per minute, the more rotations the faster the drive).

If you want real speed though, you'll want a Serial ATA hard drive (SATA), which is one of the fastest hard drives you can get without buying server grade hard drives (SCSI), which are pretty expensive. Your motherboard has to support SATA or SCSI though if you plan to purchase these kinds of hard drives, or you have to have a PCI expansion card to plug them into.

Sound Card

If you want gaming quality sound, then you definitely need to replace that stock or built in sound card for a decent gaming sound card. And if you want the full effect, go for a dolby 5.1 surround sound enabled sound card for that super crisp sound your games can produce. Mix that with some 5.1 enabled speakers, and your gaming experience just took a new turn.

Computer Cases

Ok, so computer cases are not that important for speed, but if you want your new gaming computer to look slick too, then you need a nice colored case. Your friends will be jealous, and you will finally be able to look at your computer and smile, because it looks so awesome.

Program Not Responding and Freezing? – A Way to Improve Computer Performance

Program not responding and computer freezing can be attributed to devoid of CPU or RAM resources. If one program can not obtain sufficient resources, it will stops responding.

Resources are always inadequate. The capacity of your computer CPU and RAM is given. If the hardware resource is fairly distributed to all programs, they can run smoothly. But the problem is that mal distribution of resources always exists.

When some programs take up too much resources and a program can not acquire enough resources, this program will not be able to work properly and stop responding. And when there are too many programs running at the same time, the CPU or RAM Usage reach 100% and no more resources can be distributed to each program, computer will probably encounter freezing.

There are two ways to solve the program not responding and freezing problem. One is to upgrade computer hardware. Change existing CPU for one of higher Hz or dual CPU. And upgrade your RAM to 2GB, 4GB or higher one. Then the computer has enough resources for all software.

The second method is to optimize the system and make the resource distribution fair and proper. When Windows runs over time, it is stuffed with junk files and registry keys are missing or corrupted. Too many junk files will take up hard disk space and RAM. It is necessary to clean up them regularly to free disk space and save RAM.

Another factor is the registry. Registry is the database that stores settings and information for hardware, operating system software, and non-operating system software. The settings and information is packed in registry keys which are vital to Windows system, software and drivers. Windows system need access to the key value before alloting resources to programs. Furthermore, software and drivers also needs the data to run stably.

When some data is damaged, the programs and drivers will not be able to work and system can not allot resources fairly to each programs. That is why you frequently have program not responding, screen freezing, blue screen and blank screen of death.

How to Clean a Virus-Infected Computer Step by Step

Does your PC have abnormal processes or unknown applications? Does your PC slow down tremendously? Does your IE (Internet explorer) always ask you whether you want to run some ActiveX plug-ins or debugging scripts? Typically, these are signals indicating that your PC has been infected by viruses. The following will show you how to clean a virus-infected computer step by step.

What people tend to do when their PCs are infected by viruses is to reboot their PCs. Actually this practice is totally wrong. When your PC gets viruses and you try to reboot it, you may suffer from greater loss because you are able to accelerate the virus infection and lose all data on your PC in this way. Therefore, when your PC is infected, the first tip is: do not reboot your PC immediately!

(1) The first thing you need to do is to disconnect the internet and the simplest way is to take your internet cable out from your PC if it is wired network.

(2) The second step you need to perform is to back up your important data on the infected PC. You can use a USB flash drive or optical disk to back up your important data.

(3) The third step is to kill viruses on your PC completely. You will have to enable your internet connection now. Then you will need to update your antivirus software and then run a full scan. There are various latest viruses being created each day so updating your antivirus is a possible solution to fight against the latest viruses.

But sometimes there will be exception. Even though you have tried to update your antivirus software, the viruses on your PC will not be completely removed or they even disable your antivirus software. In such circumstances, the virus will require manual removal. If you fail to remove it by yourself, you'd better ask someone else or try to find some good virus removal support to help you before the viruses cause more damage on your PC.

(4) The fourth step that you need to do after you clean the virus altogether is to change your all kinds of accounts' passwords. For example, you will need to change your Email / Face book account's password.

(5) A final tip is: if you are a LAN (Local-Area Network) user, you will need to check whether other computers within LAN are infected by the same viruses. If yes, you will need to remove all viruses on other PCs, otherwise, the viruses may spread on your PC again via the LAN.
