Ways to Restore Old Machines to their Former Glory

Just because your computer is playing up doesn't mean it's time to throw it away. Toby Green discovers five easy and inexpensive ways to restore old machines to their former glory

There are following steps:

Smarten up your security

If you feel your computer slowing down, this could be a sign that it has been breached by malevolent forces. "One of the symptoms of becoming infected is that your system starts to go down," says Con Mallon, a director at Symantec, producer of Norton security software. "It has a split personality where it's doing the things you want it to, but it's also doing what the hacker or the malware writer wants it to."

Running a virus scan regularly should pick up any nasties, but run the updates program so it has the best chance of detecting every virus.

"Anyone using a Windows PC online should have an anti-virus tool, firewall and anti-spyware utility," says Allen. "You can get all three for nothing." He recommends AVG Free (free.avg.com ) or Avast (www.avast.com ) for anti-virus; the ZoneAlarm Free Firewall (you'll need to disable the Windows version); and, for an anti-spyware program, Ad-Aware Free (www.lavasoft.com ).

Boost your memory

The amount of memory your computer has isn't only about the number of photos or songs you can store on your hard disk. Alongside that you also have RAM (random access memory), which is used by your computer temporarily while it is running programs.

The more RAM you have, the more programs your computer can cope with running. "Adding more memory is one of the best ways to boost a PC's performance," says Allen. "The more memory, the better, although the standard versions of Windows XP and Vista have an upper limit of 3GB. www.crucial .com/uk and www.kingston.com/tools can tell you how much memory your PC can handle and what type to get."

Prices vary, but you could pay as little as £15 for 1GB of RAM – in terms of a minimum to aim for, Microsoft say Windows Vista can run on as little as 512 MB, while GB would provide optimum performance.

As well as being good value, extra memory is also easy to install yourself, though any computer store can do it for you. As long as you have the right memory for your motherboard, it should be a case of popping the old memory out and slotting the new memory in www.computeractive.co.uk has tutorials for desktops and laptops.

Let a program do it for you

There are a huge number of commercial programs that claim to clean your machine at the touch of a button. One area where they can help is the registry – where settings for everything in your computer are kept. It is so important to the running of your computer that you should never attempt to edit it yourself unless you're 110 per cent sure of what you're doing.

But some of the tasks that these programs do you may find you don't need. "System clean-up utilities are ten a penny and we've found that many of them simply automate tasks home users can perform," says Allen. Not all of them have to be paid for – Allen recommends CCleaner (snipurl.com/ ba4ln ), which includes a registry cleaner.

Before you buy or use any program do your research – with so many available you need to be confident that what you use won't damage your PC, so go for a big brand or something recommended by a reviews site you trust. Make sure your registry is backed-up before editing it, even if you're confident about the program you're using – Microsoft's Help and Support website (support.microsoft.com ) gives a step-by-step guide.

Call in the experts

If you don't have the time or confidence to mess with the inner workings of your computer you may decide to call in the experts. There are independent computer shops and numerous high-street stores you can bring your PC in to, while many offer home-visits.

Tim Fairs of TechGuys, the technology experts who offer their services in branches of PC World, says that such a service can give you peace of mind. "You get the plumber to come round or hire someone to service your car. I think the same these days is true of technology in that a lot of customers would much rather have someone else do the work than take the risk."

Of course, this all costs money and Allen believes it's often unnecessary. "Everyone should at least give it a try themselves before paying for a homevisit or in-store service."

However, if you are unsure in any way about what you're doing, always consult an expert first.

Features of Energy Efficient PC

A typical desktop computer, together with a monitor and printer, can consume as much electricity as five or six powerful incandescent household light bulbs.

If left running for long periods of time - or even 24 hours a day - a computer can easily cost you more in electrical bills than its original purchase price.

While you can use the power-saving features built in to today's operating systems to put a computer into a sleep mode when it's not being used or simply turn it off, many people don't.

Computers in Internet-connected households or in the workplace are frequently left running non-stop so that they're always available for research or play.

That's why it pays to look closely at how much electricity a computer is likely to use when you're on the hunt for a new machine or upgrading components within your existing one. Computers today run the gamut from power-sipping misers to unabashed energy hogs.

And it's not always clear from the packaging which one you're signing up for.

Notebooks

Notebook computers are built from the ground up to consume as little energy as possible - and therefore to save you money over desktop machines. Not all notebooks, though, are built with power- saving in mind. Models that are touted as 'desktop replacements' typically are built around the same components that appear in full- sized PCs, and they therefore consume as much electricity - and cost almost as much to operate.

Under the hood

Whether you're evaluating a notebook or a desktop computer, the components in it determine how miserly it is, so it pays to know something about the power needs of the parts that make up any computer you're evaluating.

Central processing units (CPUs) - the main chips around which PCs are built - often use more energy than other components. While most processors today go into a low-power mode when they're not being taxed heavily by the demands of software, the maximum power usage is telling.

Intel's flagship Core i7 processor, for example, requires 130W of power, and AMD's Phenom X4 Quad-Core uses 140W. Intel's Core 2 Quad chips use 95W, while most of the Core 2 Duo chips consume significantly less, at 65W. What this illustrates is clear: today's powerful processors are also power-hungry, and the more powerful chips consume significantly more electricity and will therefore be costlier to operate.

Processors designed specifically for notebook computers fare much better. Intel's high-end Core 2 Duo chips designed for notebooks, which generally run at 2.1 GHz or better, consume either 25W or 35W, depending upon model. The Core 2 Duo U7700, which runs slower at 1.33 GHz, needs only 10W of power, while AMD's Sempron for notebooks runs at 1 GHz and requires just 8W of power.

Video cards

Today's fastest processors are typically paired with today's beefiest graphics cards, which use so much electricity and throw offso much heat that dedicated fans are required to keep them cool.

The graphics cards from Nvidia and ATI, built for running today's games and 3D applications, can consume anywhere from 117W when idle to well over 300W under load. 'Under load' refers to the power draw of the cards when rendering complex objects or powering through a game, while 'idle' refers to the power required just to have the video card turned on.

Hard drives

Hard drives are on or at the ready almost always when a computer is powered up. So they're always drawing energy. As with other components in a computer, higher performing hard drives - those with rotational speeds of 10,000 revolutions per minute (rpm) or higher - consume the most electricity. To save money, look for hard drives - either desktop or notebook - that spin at 5400 or 7200 rpm. Western Digital's 'green' drives, for instance, spin at a variable rate to conserve energy, and they consume about 40 per cent less power than comparable non-green drives.

Solid State Disks (SSDs) are increasingly popular as replacements for hard drives, both in desktop and laptop computers. While many assume that SSDs consume less power than traditional spinning- platter models, recent tests have shown that their power usage is about the same.

Monitors

If you're still using an old cathode ray tube (CRT) monitor, ditch it. Its power requirements are probably twice that of a similar-sized LCD panel. Most LCDs use fluorescent back lights, which are energy efficient. What's more, when in sleep mode, many LCDs consume just 2W or less. Better yet, monitors are easy to turn off completely. Do that if you won't be using it for a while.

Final decisions

The bottom line is that the energy efficiency of any computer - and by extension the cost of running it - boils down to how much power the individual components consume. In today's world of mix- and- match PC purchasing or building, you have a great deal of control over how energy-efficient your computer will be when armed with the knowledge of how power-hungry its parts are.

D-Link announces Green Technology solutions

D-Link Green Technology

D-Link has announced its second-generation 5-Port Gigabit Desktop Switch which provides up to 73% reduced power consumption without sacrificing network performance.

The DGS-2205 is one of four environmentally friendly small office/home office (SOHO) unmanaged gigabit switches that will ship this year with newly enhanced power-savings.

The Green technology of D-Link conserves energy by recognizing when a port is active. It is also capable of altering power usage in relation to the length of its cable, conserving energy use for both the user and the environment without any loss of performance.

Even, when a computer is shut down, switches often remain on and continue to consume considerable amounts of power. Through D-Link Green technology, the new switches can detect when a computer is turned off and will respond accordingly by powering down.

Normally, switches send full power to cables regardless of the actual length. Through D-Link’s Green technology, the switches are able to analyze the cable’s length and adjust the power accordingly.

The incorporation of D-Link Green Technology into these DGS-2200 series switches re-emphasizes D-Link’s strong commitment to protecting the environment, leading the development of eco-friendly products that comply with RoHS (Restriction of Hazardous Substances) and WEEE (Waste Electrical and Electronic Equipment) directives.

D-Link commitment to making its products more energy efficient is being appreciated by leading industry-watchers, such as PC Magazine and Laptop Magazine, which recently named the D-Link Green initiative the most innovative of 2008.

Steven Joe, president and CEO or D-Link Systems, Inc. “Our goal is to maintain industry leadership as a pioneer of Green networking technology by building in even more energy-saving features into our products without sacrificing performance.”

“We plan to continue the momentum of success we’ve realized with our first generation Green products as we seek new avenues that protect the environment and help our customers save money in the process,” he added.

Power saving equals cost saving with the new second generation D-Link with MSRP prices set at $59.99 for the DGS-2205 and $79.99 for the DGS-2208. MSRP pricing of the DGS-1016D and DGS-1024D are $219.99 and $249.99 respectively.

Apple's New Green Computer

If you are in the market for a new computer or laptop there are now greener options. Computers and laptops that are manufactured normally contain harmful chemicals, including brominated flame retardants (BFRs) and polyvinyl chloride (PVC), in the circuit boards, internal cables, connectors, insulators, and adhesives. Apple has worked to remove these chemicals from the aluminum-based MacBook family by launching green computers.

The new MacBook Pros are the greenest ever. Made with arsenic-free glass, BFR-free internal components, Mercury-free LED-backlit display, PVC-free internal cables and highly recyclable aluminum and glass enclosures, Apple’s laptop range can now be recycled a lot easier than the earlier versions. On top of all this, the battery in the new 17-inch MacBook Pro lasts up to five years or 1,000 recharges. This means that the laptop uses just one battery in the time that typical notebooks use three. Apple is also committed to using between 34% - 37% smaller packaging for the notebooks.

Apple also created the new Mac mini desktop computer which uses a combination of highly recyclable aluminum and polycarbonate, and is only 6.5 by 6.5 by 2 inches, making it a fraction of the size of a typical desktop tower, which requires less packaging and allows more units to be transported at a time.

On the technology side of things, the new Mac mini uses an advanced power management system that allows it to use up to 45 percent less power at idle than its predecessor, making it the most energy-efficient desktop computer. According to the Apple website, “Mac mini meets the stringent low power requirements set by the EPA, giving it ENERGY STAR certification. In addition, Mac mini meets the latest efficiency requirements of ENERGY STAR Version 5.0 Specification for Computers before its July 2009 effective date.”

Facebook New app Encourage Towards Green PC

Popular social networking website face book is now in Green Technology. Face book new application promises greener PC, which encourages to save environment as well as energy. It also encourage environmental and energy conservation. Many offer obvious advice like to use green technologies, save environment, use LED bulbs, but a new app offers to green up the PCs Face book members rely on to access the social networking site.

"Green Your PC," developed by Redwood City, Calif.-based SupportSoft, Inc., offers to help configure settings including your computer's monitor timeout, disk timeout and standby mode so that they comply with Energy Star and Carbonfund.org recommendations. Users can do this either by downloading a piece of SupportSoft software (an .exe file) that automatically performs the configurations or by following a tutorial written by SupportSoft that instructs users on how to change their PC's configurations themselves. So use green PC to save energy, save environment as well as money.

The app became available earlier this month for Facebook members using PCs (a Mac version is in the works). SupportSoft, a provider of third-party helpdesk services, got the idea for the app from a free service it's been offering its customers since last year. The company offers that service when customers call up with other information technology support needs, but Facebook opens up a much broader audience, which SupportSoft hopes "Green Your PC" will serve. (Previous ScientificAmerican.com coverage of Facebook apps has included one written for Burger King, which Facebook later disabled.)

"We're doing something that the majority of users don't know how to or don't think to do on their own," says Anthony Rodio, SupportSoft's executive vice president of worldwide operations. Rodio says he has no plans to offer the app through MySpace or any other social network.

It's unclear exactly what impact computer energy settings will have on the environment. But Carbonfund.org, a non-profit that advocates for renewable energy, estimates that if 100,000 computers and monitors reduced electricity use to the level set by the "Green Your PC" app, it would save more than 11 million pounds of carbon dioxide emissions annually (roughly the same as emissions from burning 13,000 barrels of oil).

Donate Your Old Computer Equipment to A Good Cause

Donate Your Old Computer Equipment to A Good Cause. Why Recycle When You Can Re-Use?

We have to donate all electronic garbage so that it can be further recycle thus use it again for good purpose. By doing so we can save environment, earth as well money. So, take steps to save energy. Got any old computer equipment lying around? You could recycle it, or you could put it in the hands of someone who will get some good use out of it.

That's the idea behind Computers With Causes, a charity that accepts old computers from individuals and small business, refurbishes them, and gives them to people or organizations who need them.

This reduces e-waste, cuts down on clutter, and puts perfectly good electronics back to work where they can help change the world for the people or groups who receive them.

According to their website, "Computers with causes evaluates each and every donation on a case by case basis. Whenever financially beneficial, computers with causes will repair, refurbish, and properly prepare donated property for placement into an educational environment or other cause we support. The ultimate goal being to maximize the benefit of your donations both financially and through educational purposes to the communities in which we live."

Functioning computers will be put back to use in the community. Non-functioning computers can even be useful, as they'll get donated to schools to help teach computer repair.

Anything Computers With Causes receives that can't be used gets recycled, using what they call a "zero landfill" process.

Donations earn you tax deductions, and some donations can even earn you a free vacation!

How to make your PC Efficient?

It costs hundreds of pounds, but your PC may have a surprisingly short life. Fresh out of the box, it runs like a dream, but after only months of use, it can become frustratingly slow. It takes ages to start up, browsing online becomes tortuous and running multiple programs at once is impossible. Plus, it could begin crashing with alarming regularity.

In more financially stable times, we might have simply bought a new computer, but this has become less attractive as household budgets tighten. There is an alternative though; perform some simple tasks and install a few upgrades and you could get your PC firing on all cylinders again.

There are two Windows utilities that Allen recommends. The first is the Disk Cleanup program, which prompts you through a series of steps to get rid of computer clutter, such as desktop icons for programs that you don't use. The next is the Disk Defragmenter – this organizes the data on your hard-drive so the computer doesn't have to work hard to access it.

Another easy task is to fully delete any installed programs that you don't need. "These eat up hard disk space and slow down the speed at which Windows starts," says Allen. "Check the list of installed programs in Windows XP by clicking the 'Start' button, opening the Control Panel and selecting 'Add or Remove Programs'." In Vista, open the Start menu and type "programs" into the search bar, then select "Programs and Features". Go through the list and select the programs you no longer need for removal."

Just don't be too gung-ho. "If you don't recognise a program, leave it be," warns Allen. "Windows and security applications store updates here and these shouldn't be removed."

Smarten up your security

If you feel your computer slowing down, this could be a sign that it has been breached by malevolent forces. "One of the symptoms of becoming infected is that your system starts to go down," says Con Mallon, a director at Symantec, producer of Norton security software. "It has a split personality where it's doing the things you want it to, but it's also doing what the hacker or the malware writer wants it to."

Running a virus scan regularly should pick up any nasties, but run the updates program so it has the best chance of detecting every virus.

"Anyone using a Windows PC online should have an anti-virus tool, firewall and anti-spyware utility," says Allen. "You can get all three for nothing." He recommends AVG Free (free.avg.com ) or Avast (www.avast.com ) for anti-virus; the ZoneAlarm Free Firewall; and, for an anti-spyware program, Ad-Aware Free (www.lavasoft.com ).

Boost your memory

The amount of memory your computer has isn't only about the number of photos or songs you can store on your hard disk. Alongside that you also have RAM (random access memory), which is used by your computer temporarily while it is running programs.
