Computer Crashes? – Ideas to Fix a Computer Crash

Computer crashing is absolutely the first tough problem to millions of PC users.When you get this problem, everything comes to a halt and what you can do is just to reboot your computer reluctantly. Most of the time, computer crashes unexpectedly even though you were playing a small game, writing down your diary, or visiting a web page. Such phenomenon predicts you that there is something wrong with your computer and it has to be fixed before it gives up completely. However, fixing the computer does not need to replace your computer with a new one. Your current computer likely just needs a little attention. To identify the reason for crashing seriously is a very necessary step before you take some action on it.

Here are some common reasons for crashing as below. You can find what is the specific factor that causes the computer crashing easily.

1. Computer Crashing caused by Hardware

*Poor Heat Dissipation* Monitor, Power and CPU will emit plenty of heat when in operation.If the generated heat is not dissipated in time, the normal operation will be adversely affected, which may result in decrease of operation speed or life expectancy. A common solution is to dispose a heat sink and a fan corresponding to a heat source. Computer will probably freezes because of the poor heat dissipation. If you use a laptop with a low quality cpu fan, you can purchase a USB fan to cool down the CPU temperature. Your computer will run more smoothly than before.

*PC is moved inappropriately” If your computer is moved to another place incautiously, some components in it would slap because of the violent vibration and results in the crashing. Therefore, I suggest you handle your PC with care.

*Dust Killer* Guess what? Too much dust in your computer will also cause computer crashing. Don’t be lazy:) Cleaning the dust regularly is another effective maintenance method to avoid PC freeze.

*Unmatch Device* If the Motherboard frequency does not match with frequency of CPU, the computer would fail to keep running smoothly but just crashes continually.

*Incompatibility between hard/software* Some 3D Application Software and special software would probably have conflicts with the hardware of some computers.

*Memory Malfunction* Loose or low quality memory would cause computer crashing frequently. You need to check the memory and plug it into the mainboard again. If there is something wrong with the RAM, please try to clean the gold finger.

*Hard Drive Malfunction* Computer Crashing also could be caused by the aging of PC hard drive or the bad track of the HD. I advice you download or purchase some HD diagnose tools to detect and fix HD problems. If the hard drive is damaged seriously then you have to get a new one to replace it.

*CPU Overclocking* Overclocking of course will improve the CPU working frequency but meanwhile it also will bring unsteadiness to the computer. So get your CPU to the normal frequency right now.

*Conflicts from HD Resources* To remove the potential conflicts among PC devices, you can enter the “safe mode” and adjust some settings in the “Controle Panel”—“System”–“Devices Manage”. To fix some errors caused by driver program, you can modify the registry with this instruction: Click “Start” menu—“Run”–Type in “regedit” and find out the relevant registry keys. Delete them. If you feel hard to do this, it is highly recommended that you download registry cleaning software to fix the invalid and wrong registry entries/keys on your computer to reduce the probability of computer crashing.

*Shortage of Memory* If you try to run some large applications on the computer with poor memory, it is no doubt that probability of crashing would be increased.

2. Computer Crashing caused by Software

*Virus Infections* Virus,Trojan,Worms,Spyware,Malware, etc will absolutely affect computer performance and cause computer crashing frequently. To install a kind of anti-virus software on your computer is very necessary as a PC user.

*Improper Setting of CMOS* CMOS, short for Complementary Metal Oxide Semiconductor, is a low-power, low-heat semiconductor technology used in contemporary microchips, especially useful for battery-powered devices. So make sure the settings of it are correct.

*Delete System Files Accidently*

If you delete some system files that the operating system could not work properly. Of course there comes the computer crashing. To fix this problem, you can insert the installation boot diskette with the same version of operating system then type in “SYSC” and transfer the whole system files again. Problem would be resolved very quickly. Or you can download Registry Easy and use the “files recoveryer” function to get those system files back!

*Broken Initialization files* Some initialization files such as System.ini, Win.ini, User.dat, System.dat are vital to Windows Startup.If those files were broken or get something wrong, computer will fail to start and also will freeze even crash!

To avoid and fix computer crashes, I highly recommend you try to use registry repair tool to optimize and protect your computer regularly. You can download the free trial to scan your computer errors from now on.

Grid Computing – The Future of Internetworking

If you are using the internet from your desktop, then your computer is part of a network. This network in turn is part of another network. In short, the internet is a networking infrastructure. It was the result of some visionary thinking by the people in the early 1960s that saw great potential value in allowing computers to share information on research and development in scientific and military fields. Shrinking computer sizes and information sharing services made it possible for every computer in the world to interconnect. The ‘World Wide Web’ is a service built on top of the internet which enables millions of computers around the world to share information.

The internet has served well so far but has a few shortcomings. Scientists and computing experts are always on the lookout for the next leap forward. The internet allows you to only share information and nothing more you can think of apart from that. In order to address this issue, the experts have devised a new system which is called the ‘Grid’. A grid computing system is a type of parallel computing system which enables us to share computing power, disk storage, databases and software applications. The term ‘Grid’ first appeared in Ian Foster’s and Carl Kesselman’s seminal work – The Grid: Blueprint for a new computing infrastructure. Ian Foster is the Associate Division Director in the Mathematics and Computer Science Division at Argonne National Laboratory (United States), where he leads the Distributed Systems Laboratory, and he is a Professor in the Department of Computer Science at the University of Chicago. In one of his articles, Ian Foster lists these primary attributes of a Grid:

1. Computing resources are not administered centrally
2. Open standards are used
3. Significant quality of service is achieved

A grid computing system, also known as a distributed computing system, relies on computers connected to a network by a conventional network interface like the ‘Ethernet’ (the port into which you connect your LAN cable). These computers have the capability to combine and yield better results than a supercomputer. These computers are independently controlled, and can perform tasks unrelated to the grid at the operator’s concern. This is what Ian Foster indicates in the first point of his checklist.

The striking feature of a grid computing system is that it enables sharing of computing power. This is also known as CPU scavenging in which a computer steals the unused cycles of any other computer. These cycles are nothing but the idle times of a processor in a computer. Shared computing is the act of sharing tasks over multiple computers. In other words, it is as good as getting the same job done from a bunch of people rather than a big strong man. As a result, a task which took days to complete will be achieved over a relatively small period of time. IBM is currently working on developing a global scale supercomputer based on the concept of shared computing. They have named it as ‘Project Kittyhawk’ and it will run the entire internet as an application. Shared computing is one of the services that a grid will provide.

Desktops, laptops, supercomputers and clusters combine to form a grid. All of these computers can have different hardware and operating systems. Grids are also usually loosely connected in a decentralized network, rather than contained in a single location, as computers in a cluster often are. Hence, a grid’s flexibility and additional features distinguish it from its competitors. Moreover, a grid is built from open standard protocols and interfaces like TCP/IP protocol suite which is important to realize internationalization rather than subjugating it to local limits.

In addition to shared computing power, a grid allows you to share disk storage, databases and software applications. Altogether, this system will be very helpful to people belonging to different categories, ranging from scientists to consumers. Most of the computers in mid size and large size organizations are idle for a higher percentage of time. These idle processors can be utilized for other important tasks by the means of CPU scavenging. Different scientists of the world would like to visualize their applications in real time rather than wait for ages till their results are shipped, verified, and then sent back. With the help of grid, people from different fields of expertise will be able to hook up to remote computers and share their findings. This won’t only speed up the process but will also produce accurate results.

One of the biggest projects on grid is being carried out in Switzerland by the European Organization for Nuclear Research (CERN). Thousands of desktops, laptops, mobile phones, data vaults, meteorological sensors and telescopes will constitute the biggest grid which will produce an annual database of roughly 15 million gigabytes. This event will become possible when two beams of subatomic particles called ‘Hadrons’, will collide in the ‘Large Hadron Collider’ – A gigantic scientific instrument 100 meters underground at Geneva, Switzerland. Thousands of scientists around the world want to access and analyze this data, so CERN is collaborating with institutions in 33 different countries to operate a distributed computing and data storage infrastructure: the LHC Computing Grid (LCG).

To constantly reap the benefits of such a system, it is important to make sure that the computers performing the calculations are entirely trustworthy. The designers of the system must thus introduce measures to prevent malfunctions or malicious participants from producing false, misleading, or incorrect results, and from using the system as an attack vector. In a grid, computers drop out either voluntarily or due to their failure.

Many projects over the grid are underway and the day is not far when it will be globally implemented. But for any new technology to be successful, it needs to be given a chance. Its fate will be in our hands. There is going to be a lot of chaos and confusion before the scores are out. The chances for the grid to emerge as a successful computing system are high, and with it our understanding of the universe is going to change.

How to Speed Up Your Computer – Top 8 Easy Ways to Speed Up Your Computer

As we know, the speed of computers would probably degrade after using for one or two years. How to speed up computer performance is what every PC user concerns about. If users never maintain their computer then they would encounter extremely slow speed computer problems. The system would eventually takes long time to respond a user’s operations such as surfing the Internet, playing PC games, running some applications even opening files. This article discusses how to speed up your computer and maintain the performance to keep it running smoothly. By following these 8 easy ways, you can enjoy your computer at a very high speed without purchasing a new one.

Are you ready? Let’s go!

1. Remove any virus, spyware, malware and worms to speed up your computer.

I strongly suggest you install some kind of anti-virus program on your computer to prevent any infection from virus, spyware, malware and worms. They not only slow down the startup speed but also will affect your whole computer performance even crash the system. After removing the infected files or virus, the speed of computer would be upgraded.

2. Defragment your system to speed up your computer.

The Windows operating system places files and programs on a hard drive. One file will not necessarily be located in one physical place. Over time, a hard drive can become fragmented with hundreds of files broken up in many locations across the drive. Ultimately, those fragment can slow down a computer’s speed and respond time. So to defragment the system is an effective way to speed up your the computer. To defragment your system, follow this steps: Go to My Computer, then to Local Disk, click on Tools and follow the instructions.

3. Terminate unnecessary programs launching automatically at the Startup.

If there are too many programs run automatically at the system startup, you will have to wait for a long time before entering system totally. To speed up your computer, you can try this method: Click “Start” menu–Run and then type in “msconfig”. From there please terminate some unnecessary services and applications which run automatically at the system startup. And reboot your computer finally.

4. Clean useless DLL files in the memory to speed up your computer.

Too many useless DLL files could affect the speed of computer because they would occupy much memory space so that cause the computer slow performance.

1)Click Start menu–Run–Type in “regedit”

2)Find outHKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersion Explorer

3)create a new DWORD name it as “AlwaysUnloadDLL”.

4) Modify the data as “1”

Or you can download some registry cleaners to speed up your computer by cleaning invalid and missing DLL files of system.

5. Increase RAM space.

More and more programs require a lot of RAM space to run properly. If you do not have enough RAM to run applications, you will feel your computer becomes extremely slow and you have to waste much time on waiting for the responding from your computer.

6. Clean up unused desktop icons to speed up your computer.

Too many icons on the desktop also will slow down the speed of computer. By following these steps, you can clean your desktop within a few of seconds. a. Open Display in Control Panel. b. On the Desktop tab, click Customize Desktop. c. Under Desktop cleanup, click Clean Desktop Now. d. Follow the directions in the Desktop Cleanup Wizard.

7. Decrease kinds of font on your computer.

Although Microsoft Company claims that Windows system could be installed 1000–1500 kinds of font, if you get more than 500 kinds on your PC then slow speed problem would come actually. So I advice you remove those useless fonts to optimize the speed of computer.

8. Clean registry of system to speed up computer.

Guess what? Many computer speed problems relate to registry errors on your computer. Registry is a crucial part of computer system. Invalid and missing registry of system would absolutely cause numerous PC errors including the computer speed problem.

Here is What to Do When Your Computer Crashes

It is extremely frustrating and annoying when your computer crashes. This is an all too common occurrence. Unfortunately when this happens most people do not know what to do. Here is help so what to do when your computer crashes and how to prevent it in the future.

Knowing that computer crashes are inevitable it is important save your work regularly. There is nothing worse than losing valuable data or a document you have spent time working on, because your computer crashes unexpectedly.

So what causes a crash and what can you do when your computer crashes?

The first thing you need to do when your computer crashes is to ascertain the reason behind it. This can often be difficult if the computer completely shuts down or goes to a black screen. But if you pay close attention you will be clued in to the symptoms and signs that may help you to store your data and also prevent a crash.

Be sure to resist any emotional response when your computer crashes. Some people think tapping or hitting their computer can fix the problem. Others experience rage and want to throw it out the window. Neither action will help matters.

On most occasions your computer crashes when because it gets over heated. The intense heat generated causes your computer to temporarily shut down in order to cool the system and re boot again. You need to be cautious with over-heating problems as intense heat generated can result in hardware damage or even failure needing you to replace a drive.

If your computer is stored in an area that does not get good ventilation it can over heat easily. Also, if the computer housing has a fan at the back and it gets covered with dust this will not allow air to flow properly and that can lead to over-heating.

A surge in the power supply can also cause your computer to crash as it cannot handle the excess power. In severe cases your computer may not power up at all. This can usually be avoided by using a surge protector power strip.

Software problems involving viruses or software conflicts can also be the cause of computer crashes. These are problems a computer technician is best at solving.

Another common cause for a computer crash is the one involving the registry files of your personal computer. Very few personal computer users are aware of the registry folder that sorts, stores and keeps track of all the valuable information on the software and hardware, including drive space and other programs that are essential for your computer to run smoothly.

Registry database is perhaps the most frequently used as well as the most important part of the “Windows” operating system. It is also the biggest cause of most computer errors and computer crashes. This is because “Windows” requires accessing the registry database for everything.

Hundreds of registry files are opened edited or in use every time that Windows perform any task on your computer. That sometimes creates confusion leading to improper saving of such files. As a result these files often get damaged or even corrupted. So the Windows find it difficult to read such files which slows down your personal computer and leads in error message or a total computer crash.

The way to prevent registry computer crashes is the use of a registry cleaning device on a regular basis, and defragmenting your computer once in a while. Once you download a good registry cleaning device and schedule it to clean your computer at least once a week, your computer will run more efficiently with fewer error messages and not crash as often.

Custom Computers Can Save You Money

When the typical consumer begins searching for a new computer, they usually look for the best deal from the biggest, name brand super store they can find — but is this the best computer system for your money and will it really do everything you need it to?

If your at the cross roads in your search for a new computer, let me offer you some professional computer advice before you spend your money on a name brand system from the super store down the street. There are several advantages to buying a custom computer from a professional system builder.

Guarantee

If you purchase a system from a professional builder, you can be assured of the quality that goes into building your new computer system. Everything from the parts, to the time spent installing your custom system will be done with extra attention to detail. You can be guaranteed that a custom built computer will do everything you envisioned your computer doing and usually more. All computers from a system builder will offer a guarantee of some sort. Most reputable builders offer a 90 day parts & labor warranty from the date of purchase, on all new custom computer systems.

Quality

All the parts purchased for a custom computer are thoroughly reviewed to make sure the components perform as expected or better before they are purchased, and ultimately installed in the customers new computer. All custom systems are designed, built, tested, packaged, and shipped with a great deal of pride from the builder. This typically goes a long way towards the value of the final product you receive for your money. The old saying you get what you pay for could not be more true. Custom computers are built with you in mind and every little detail is taken into consideration.

Performance & Reliability

Professional system builders will generally test each individual computer more thoroughly. The individual attention applied during the building of a custom computer can assure first rate quality, and reliability not available from typical mass-produced, name brand computers. High quality, custom built computers will typically perform better when running newer applications; and especially when running hi-def games that require a great deal of video processing power. You can be assured that a custom built system can handle any application or game that you throw at them.

Expandability

Custom computers will save you money in the long run due to the expandability they provide. Name brand computers are designed and sold; such that when technology advances you must live with the old computer or buy a new one. When you own a custom computer you have the option to upgrade only old hardware that needs it, while maintaining any serviceable components; therefore, extending the service life of the computer and all the hardware it uses.

Usability

Usability is important because you know your computing routine and needs better than anyone. Custom built systems can be catered to your exact specifications based on your individual computing requirements. You get the savings you deserve by not buying hardware you really do not need, and the performance you want because you helped design it yourself. With a custom built computer system your productivity will increase, and anything you do on the computer will be done with ease.

Serviceability

All electronic devices will eventually fail, and yes that includes computer systems. When the time comes to get repairs performed on your computer, you will find that using “off the shelf” parts as opposed to “proprietary” components, like name brand manufacturers use, means that custom computers can be repaired by just about anyone. The warranty of some prebuilt, name brand computers require repairs to be performed at a particular service location, and with specific parts, which may mean repairs take much longer. The parts for some of these name brands can even become obsolete after only a few years. This means you would have to buy a new computer if you were unable to get the part to repair it from the manufacturer. Custom computers can be repaired with “off the shelf” parts from hundreds, if not thousands of different vendors. This makes the parts less expensive and more readily available when your computer needs repaired.
