My Computer Keeps Shutting Down Randomly

Computers that shut down randomly will be suffering from one of several possible problems. In order to fix this issue, it's essential that you're able to fix the problems that cause your Windows computer to shut down, and having used PCs for many years, we've found a very simple way to combat this problem for good.

The first and most probable cause of your computer's random shutdown problem is from overheating. When computers run, they generate a lot of heat, which is why they have all sorts of fans inside. However, if your computer is not cooled enough, it can act in very strange ways, including shutting down randomly. If your system gets too hot, then it will just close down in an attempt to cool off.

Fixing the problem of overheating is actually very simple. If you have a laptop, make sure that it's not hot underneath. If it is hot, then you should put it onto a desk or flat surface and allow the fans underneath to work. It's often the case that people will smother the fans on their laps, causing laptops to overheat and shut down. If you have a desktop, simply take the side off the case and then get a desk fan and let it blow onto the inner-workings of your system. This will cool it down enough to let you see if the overheating problem is actually what's causing your PC's problems.

The other big cause of this problem is actually to do with Windows itself. Windows often shuts down your PC randomly if the settings that it needs to run are unavailable. The problem is that whenever you use Windows, it's constantly reading 100's of settings from the "registry database", and if any of those settings are damaged or corrupted, Windows gets highly confused and can cause your PC to shut down.

The registry database is a central storage system for the files and settings of your PC. Basically, whenever Windows is being used, it needs to recall a large number of files and settings that make your computer run smoothly and effectively. The registry has been a central part of Windows since Windows '98, but it's one of the major reasons why computers will just shut down randomly. To fix this problem, you should look at using a "registry cleaner" to scan through the registry and fix any of the damaged settings or files that are inside it. Registry cleaners are software programs which scan through your system and allow it to quickly find and fix any number of issues inside your system. These programs are software tools and are very easy to use - you just need to download one from the Internet, install it and let it fix any of the issues on your PC. It will remove all the problems it finds and should make Windows run a lot more reliably again. is a B2B Portal marketplace that opens virtual doors to assists buyers & sellers trade with each other at a reliable, common platform, and promotes their products to local and international markets.

McAfee's 2011 List of Threats

With the New Year fast approaching, tech enthusiasts are very excited about all of the latest technology that is being introduced in 2011, but what about the possible security concerns that come with all the new technology? On Tuesday, December 28, 2010, McAfee released their 2011 list of threat predictions. The company said, "The list comprises [the] most buzzed about platforms and services, including Google's Android, Apple's iPhone, Foursquare, Google TV and the Mac OS X platform, which are all expected to become major targets for cybercriminals."

"We've seen significant advancements in device and social network adoption, placing a bulls-eye on the platforms and services users are embracing the most," said Vincent Weafer, senior vice president of McAfee Labs, in a statement. "These platforms and services have become very popular in a short amount of time, and we're already seeing a significant increase in vulnerabilities, attacks and data loss."

McAfee will have to work especially hard to fend off the increasingly sophisticated malware that will be targeting Apple in 2011. So far, the Apple Mac OS platform has been decently secure, said McAfee. The iPhone and iPad are growing increasingly popular in the business realm though, and McAfee is afraid that with the general lack of knowledge about how to secure these Apple devices Apple botnets and Trojans could be a frequent occurrence and become a serious issue.

The biggest thing that people need to be really careful about is social networking sites. McAfee said that sites like Twitter and Facebook can easily fall prey to problems like URL shortening scans. They continued saying that they knew that utilizing abbreviated links does make it easier to condense your 140 character limit Tweets, but sometimes these links are also an easy way for criminals to mask and direct users to malicious Web sites. Each minute there are more than 3,000 tiny URLs created. Due to these astronomical numbers, McAfee said that they expect to see an increasing number of URLs that will be utilized for spam, scamming, and other malicious purposes.

Although a recent study showed that only 4 percent of adults really use location-based services, companies are continuing to release location-based features including Foursquare, Google Latitude, Facebook Places, and more. McAfee warns that the information that is shared on sites like these could easily enable cyber criminals to formulate a targeted attack. They also predicted that in 2011 there will be an increase in the use of this type of tactic across most of the popular social networking sites.

A lot of these location-based services that people utilize are used via their mobile phones. Because of this, McAfee is also predicting a “rapid escalation” in the number of mobile attacks due to “widespread adoption of mobile devices in business environments, combined with historically fragile cellular infrastructure and slow strides toward encryption."

McAfee also said that the increased use of Internet TV connections could pose a serious security risk. If manufacturers just rush into releasing their products, they could run into some major issues with suspicious and malicious apps on platforms such as a Google TV device. "These apps will target or expose privacy and identity data and will allow cybercriminals to manipulate a variety of physical devices through compromised or controlled apps, eventually raising the effectiveness of botnets," McAfee said.

These weren’t the only things that McAfee had on the threat list that they released. The list also included:

Hacktivism: McAfee is predicting that there will most definitely be a rise in the number of possibly politically motivated cyber attacks. "More groups will repeat the WikiLeaks example," McAfee said. They continued saying that unlike WikiLeaks though, the strategy will be much more sophisticated and leverage social networks.

Friendly Fire: McAfee is saying that there will also be a rise in the use of malicious content that is disguised as an e-mail from a source that you know. There is “signed” malware that works to imitate legitimate files that McAfee is afraid will be much more prevalent. They also said that “friendly fire,” which is a threat that seems to come from your friends but really is a virus such as Koobface or VBMania, will become a much more prevalent choice by cybercriminals. McAfee also said that these attacks go hand-in-hand with social network attacks and that these social network attacks could quite possibly eventually overtake e-mail attacks.

Botnets: McAfee Labs is predicting that with the merger of Zeus and SpyEye that there will be more sophisticated bots that will be produced because of the advancements for bypassing security mechanisms and law enforcement monitoring. McAfee Labs also says that they expect to see an increase in botnet activity that begins to adopt data-gathering and data removal functionality, instead of the more common use of sending spam.

Well, one thing that can definitely be taken from McAfee’s 2011 list of threats is that there are definitely threats out there that users want to avoid. Security is a big issue that many people tend to avoid, including myself. Protection and caution is necessary and is something that people really need to pay a little more attention to.

Browser Wars Heat Up for Microsoft

"I fear all we have done is awaken a sleeping giant...", those were the words of Admiral Isoroku Yamoto after the attack on Pearl Harbor, and it also seems to be the feeling people have toward Microsoft and the company's entrance into the "browser wars" we are seeing today.

Back when Internet Explorer first came out, it was a high performance browser with a lot of useful functions. However, those days were finite, and Microsoft got branded with the reputation of producing crappy browsers, a reputation that IE7 and IE8 did nothing to improve upon.

In 2010, however, a long effort to reactivate the company's browser projects showed promise in IE9. As of right now, the application is still in beta form, but it has already shifted the browser market dramatically.

Internet Explorer 9 supports any and every kind of Web standard including a ton of HTML5 features like built-in video, CSS3 for advanced formatting, professional typography and SVG for smoothly resizable graphical elements. IE9 also speeds up the execution of web-based JavaScript programs. This development did manage to alert browser rivals for one top priority today, hardware acceleration. The software itself is accompanied by a push by the industry where Microsoft is educating Web developers and contributing to the development of standards.

It does appear that it may take a little while before web developers trust that Microsoft is serious about browsers again. It also seems that people still using the ancient IE6 will still be wary of upgrading. One thing is clear, Microsoft is paving the way for a new browser future where web sites as well as web applications become more fluid, interactive, polished and powerful.

In terms of Microsoft, Internet Explorer 9 has come in at exactly the right time. The battle with IE has always been against Firefox, however, Google's Chrome has brought in a new era of fierce competition. I think it is safe to say that Google knows a little something about the internet, and the company has a major agenda of web applications to pursue as well as a big enough presence on the web to allow it to make new technologies relevant by building them into its browser and web site.

Early in 2010 Chrome passed Safari by Apple for third place in the rankings of browser usage, and its growth carried to almost 10% of usage in November. A new phase of Google browser ambition is just taking off as well. The Chrome Web Store, which was designed to promote web-based applications and Chrome OS, allows people to find and purchase nearly any web app they want.

Chrome OS is much more of a departure from existing technology than just a browser. Google only offers it built into hardware. Google has done a good job with Android, but it is still unclear as to how well Chrome OS will fare with consumers and businesses.

Firefox's percentage of browser usage has remained consistently flat for most of 2010 thanks to Chrome. There are big things planned for Firefox 4 including many new features and performance enhancements. The problem is that Mozilla failed to meet a 2010 deadline and has since been pushed into 2011.

Apple's Safari has steadily increased in usage share with a few signs that the Windows version is catching on. Safari has been the principle sponsor of the open-source WebKit project, the same project both Safari and Chrome are based on. However, Google is steadily increasing.

One notable feature of Safari 5 that arrived in July was extensions that have the ability to customize the browser's behavior. Opera, the browser currently ranked 5th, is building them into Opera 11 which is the upcoming version of the browser which will match Chrome and Jetpack, the upcoming browser from Mozilla.

Adobe Systems, maker of Flash Player plug-in, had a particularly difficult year but ended on a good note. Apple, not surprisingly, did not budge on their ban of Flash from iOS devices directly, however, it did relent on blocking an Adobe tool that allows you to convert Flash apps to native apps. Google and Adobe forged an alliance due to the very public fight between Apple and Adobe which resulted in Flash support and promotion within Android.

The browser market combines competition between makers with cooperation as all the companies seek to advance the possibilities that can occur on the web. HTML5 standardization has sprouted emotional clashes between different groups involved as the specification moves more under the control of corporate powers.

The mobile market is also a big challenge to the web. Native software can offer better interfaces as well as faster performance than traditional web apps on mobile devices. However, it is still clear that the web as well as the tools for using it are clearly on the rise.

Find And Fix Computer Restart Problem

If your computer is having automatic restart problem and you do not know why, you are on the right page. In this article I am going to help you troubleshoot your PC restart problem and we will try to find and fix your PC for automatic restart issue.

There may be two major probabilities behind this PC restart issue.

1. Hardware Problem.

2. Software Problem.

It is learnt by experience that, when ever computer got restart problem majority was because of software issues. So before we doubt on any newly installed hardware or peripheral device, let's check for any possible software issue.

Ask your self, have you installed any software recently after which your PC is being restarted accidentally at anytime? If so, try removing that newly installed software. IF you have not installed any software recently, then doubt goes on to computer virus. About 90 percents of computer issues happened just because of virus infection. So, if you think your computer might be infected by virus attack, you should consider full format of PC instead of installing antivirus only, because in most cases, cleaning viruses by installing antivirus software on infected PC do not help. So what I mean here by full format is

a. Format your system drive and reinstall your Operating System.

b. Install your hardware drivers,

c. Before doing anything else, install latest antivirus software and update it. Run full scan of your pc and remove any viruses found.

d. Install all other necessary application software.

It must be enough to solve your computer restart problem if it was due to software issues. If the problem remains unsolved, then doubt goes on to hardware issues.

Again ask your self, have you installed any new hardware like CD drive, RAM, Extra Hard Drive, PCI Card? If so, simply remove it and your problem might be resolved. If you not have installed any hardware and restart issue is still not fixed with above mentioned method, there are chances of faulty hardware issues.

You may try replacing following hardware one by one with your friend or family who is ready to let you allow playing with his PC. So you can find faulty hardware your self and can save service charges of computer hardware consulting person. You may simply purchase that device and replace your self.

1. First of all replace your RAM.

2. If your RAM is OK, replace SMPS (Power Supply).

3. Then try replacing CD/DVD Drive, Hard Drive, and CPU Fan one by one.

4. If everything seems to be OK, final doubt goes on to processor or mother board. If you are not able to replace it with your friend or family, it's time to consult computer hardware engineer. Do not forget to tell him about all above procedure your have done to save time and cost.

What Is Computer Software, Application Software And Systems Software?

A computer's software refers to a program (or a group of programs) which give a computer instructions on what to do and how to operate. Software programs can provide one main task, or multiple main tasks.

As an example, a program designed to edit digital photographs has one key task (i.e. to allow for editing of photos) - naturally it would have numerous sub-tasks though (i.e. red eye removal, color correction features, resizing and cropping/cutting of an image).

On the other hand, a computer's operating system (a complex piece of software which basically handles and runs the entire computer) would carry out many main tasks - for example handling input and output (i.e. the user typing in with a keyword, or audio coming out of speakers), memory allocation, managing the computer's hardware components (these are the electrical components which power a computer) and much more.

Software can be grouped into roughly two groups: application software and systems software. Essentially, software which facilitates just one main task (for example, photo editing software as in the above example) would be counted as application software. This is contrasted to systems software which refers to complex, multi-task programs which help to run the entire system - such as an operating system.

These two main groups of software are discussed in more detail below:

Application Software

This is software which is installed on an operating system (See "Systems Software" below for more information). As mentioned above, this type of software tends to perform just one main task. Another example of application software would be a website browser: this is the program which you are probably using right now to view this article. Examples of a browser include Internet Explorer, Google Chrome and Mozilla Firefox. In short, their main task/function is to facilitate you in surfing the internet.

Other types of application software are as follows:

  • Word Processing - this type of software allows you to type up documents and letters. Examples include Microsoft Office Word and Open Office.
  • Antivirus Software - this type of software helps protect your computer system against malicious threats such as viruses and malware. Examples include Norton Antivirus, Kaspersky Antivirus and AVG Anti-virus.
  • Photo Editing - this type of software can be used to edit and manipulate photos and other digital images in various ways. Examples include, Corel PaintShop Pro and Adobe Photoshop.

Systems Software

This type of software is quite accurately described as being at the very core of any computer system. Without systems software, a computer could not really function. In short, it manages every aspect of a computer system - from how the hardware interacts with the software ('drivers') to giving the user an interface and platform to interact with the system ('operating system'). The operating system - or 'OS' - is the software that loads up after your computer is switched on. It's where all application software is installed on. Examples of an OS include Microsoft Windows (XP, Vista, 7 etc), Linux (Ubuntu, CentOS) and Apple Mac OS X.

Other types of systems software include device drives (these make the hardware components function correctly with the software and computer system) and utilities (these are also called 'utility tools' and they help monitor, maintain, check and analyze different parts of a computer; such as 'Task Manager' and 'Disk Defragment on Windows OSes). is a B2B Portal marketplace that opens virtual doors to assists buyers & sellers trade with each other at a reliable, common platform, and promotes their products to local and international markets.

Why Do We Call Software "Software"?

The word "software" has actually been in use for decades before the invention of the computer - it was actually coined in 1851 in the cotton and wool mills of North West England to describe clothing and cloth which had a superior finish - it was quite literally soft wear.

The modern source of the term, "software", dates back to 1960 and was used to describe the programs which were run on a computer, itself termed "hardware".

Hardware was a term borrowed from the tools, plant and machinery vendors who referred to their goods as "hardware", as in the hardware store - a popular term used widely in society those perhaps less today. In the pre-computer era, hardware was more likely to be used to refer to a hammer or circular saw than an electronic gadget.

The first use of hardware as it applies to computers and peripherals is thought to have originated from the NASA rocket development teams who designed, built and tested the rockets and systems which would one day take men to the moon. Software was used a natural distinguishing term to separate the essential differences between the tangible, physical electronics and the programs and applications designed to operate upon them.

The term "software engineer" was instituted at NASA as well, and this designation spread throughout the military and scientific community in North America and from there to the rest of the world. The term software was also used to impose a feeling of inferiority upon programmers - it was not a badge of honor or respect when it was initially used. At this time in the fast but very new development of the computer, the hardware was considered to be much more important and far more valuable than the programs which would run on them.

Companies such as IBM built themselves into huge conglomerates based solely on the value they saw in the hardware they were manufacturing. It took a visionary geek, who had dropped out of Harvard. to see the error in this way of thinking, and he along with some of his close friends managed the deal of the millennium - his name is Bill Gates.

Microsoft was founded as a software house and the big break for the company came when IBM negotiated to use Microsoft's Disk Operating System (DOS) on its machines. During the meeting which sealed the deal, Gates asked if his company could retain ownership of the software, and IBM readily agreed - they saw no value in it, indeed, at this time you couldn't even obtain a patent for software of any description (the US Supreme Court did not rule that software could be patented until 1981).

Microsoft went on to market DOS worldwide, including to IBM clone manufacturers who undercut "Big Blue" with cheaper, but equally well performing machines. Possessing ownership of the operating system gave Microsoft a worldwide advantage over any other software application developer because to run well on a machine powered by DOS; if the application software would not run well with DOS, it didn't sell.

Breakthrough by IBM May Bring Us Exascale Supercomputers

If you are one of the people out there that doesn't think that a supercomputer seems good enough, then you probably work at IBM. Researchers at IBM have just made a breakthrough in using light pulses to help accelerate the transfer of data between chips. If this works out like the people at IBM think it will, then it could quite possibly increase supercomputer performance by more than a thousand times.

This technology, dubbed CMOS Integrated Silicon Nanophotonics (I feel smarter already), integrates optical modules as well as electrical modules on a single piece of silicon. This allows electrical signals created at the transistor level to be transformed into light pulses, seemingly allowing chips to communicate faster according to IBM silicon photonics research scientist Will Green.

IBM believes that this new technology will lead to massive advances in supercomputer power. The fastest supercomputers we have around today max out at nearly 2 petaflops which, for us lay people, registers into two thousand trillion calculations per second. The photonics technology could increase this number to a staggering trillion million calculations per second. Yeah, a MILLION TRILLION calculations per second, otherwise known as an exaflop. This would help IBM achieve their goal of building an exascale computer by the year 2020.

According to Green, "In an exascale system, interconnects have to be able to push exabytes per second across the network. This is an interesting milestone for system builders who are looking at building exascale systems in 10 years."

The possibility of integrating multiple photonics modules onto a single substrate or onto a motherboard is here, according to Green. Newer supercomputers already use optical technology for chips in order to communicate. However, this usually occurs at the rack level and mostly over a single wavelength. This breakthrough will allow optical communication simultaneously at multiple wavelengths.

The good thing about this technology is that it can be manufactured on a standard chip production line. Another benefit is that it also needs no special tools, making it extremely cost-effective. The current demonstration used a 130-nanometer CMOS manufacturing node. However, IBM plans on pursuing integration into "deeply scaled sub-100 nanometer CMOS processes," according to Green.

The technology aims to replace copper wires. As you know, copper wires are widely used today for data transfer between chips. Optics can get a speed increase for distances as short as a few centimeters to as long as a few miles and even consumes less power. Eventually, IBM hopes to use optics for on-chip communication between transistors as well. According to Green, "There is a vision for the chip level, but that is not what we are claiming today."
