Hardware Support for Windows 7


Hardware Support for Windows 7

February 01, 2009 by Jason
Even though Windows 7 is essentially the evolution of Windows Vista, as the operating system is available in public Beta, users of the development milestone will inherently come across glitches, including hardware incompatibility problems. Furthermore, some Windows 7 Beta Build 7000 testers are bound to run into incompatibility issues even with Microsoft’s own hardware products, namely the peripherals that the company is building through its hardware division. However, the software giant already has software in place designed to make its hardware products play nice with Windows 7 Beta.
According to Microsoft, the Habu Laser Gaming Mouse and the Reclusa Gaming Keyboard do not have Beta software available for Windows 7 Beta. “Habu Laser Gaming Mouse will continue to have basic functionality without an additional software download. Reclusa Gaming Keyboard will continue to have basic functionality without an additional software download,” the company informed. Read More»

Turn your PC into a Super Computer

January 21, 2009 by Jason
What, exactly, are supercomputers? The clue is in the name, really: they’re powerful computers capable of calculating many millions of floating operations per second (FLOPS) essentially, they’re very, very fast.
While any array of powerful computers, such as a modern-day web server which consists of several motherboards (the main circuit board of a computer) running in parallel can be considered a supercomputer, generally the term is reserved for machines that dedicate their entire hardware to one complex task at any given time.
Take the NEC Earth Simulator in Japan, for example, which was created specifically for modelling weather problems associated with global warming. Or the world’s fastest computer, BlueGene/L at Lawrence Livermore National Laboratory in the US, which simulates the behaviour of biomolecular structures and protein folding. It’s capable of 600 trillion FLOPS (tera-FLOPS or TFLOPS), whereas, the six-year-old Earth Simulator is only capable of 36TFLOPS. BlueGene/L won’t hold the top spot for long, though. Supercomputers twice as powerful will be online soon. Read More»

Windows Laptop Selector Guide

September 02, 2008 by Jason
While Apple’s Macs running OS X are without a doubt making inroads into the territory owned by Microsoft and PC makers with Windows machines, the fact of the matter is that the Redmond company and its OEM partners still account for the vast majority of the operating system and computer markets.
As far as consumer trends are concerned, there is a palpable shift from traditional desktops to laptops, and Microsoft is not only delivering Windows Vista, an operating system tailored to a mobile lifestyle, but it is also prepared to offer guidance on the acquisition of a new computer. From the Windows Guide library, the Redmond company has made available for download the Windows Laptop Selector Buying Basics.
“GHz? MBs? SDRAM? You don’t have to speak nerd to find a great laptop. Our Buying Basics makes it simple and straightforward to understand what you need to know when looking for your next PC,” reads an excerpt from the guide. Of course that the decision to buy a new machine orbits around money. “Many people see price as the biggest factor when buying a PC. A bargain-basement price may seem tempting now, but will it give you the laptop you want for the long haul? Technology changes rapidly and even if you spend less today, you might end up paying more tomorrow just to keep up with new software.” Read More»

Improve performance by tweaking your hardware

August 21, 2008 by Jason
Learn how your hard drive and graphics card impact your system’s performance, and dig deep under the bonnet to discover and fix hardware issues.
In previous guides we have looked at improving your system’s performance by simply removing unwanted programs. The next area we want to understand is the impact your hard drive and graphics card have on your system.
Before we start examining your computer, we need to see what Windows Vista believes is possible from the system when it’s working at its best. Searching for ‘Performance’ in Start Search should lead you to the Performance Information and Tools analysis of your system. If any numbers are low, then you may wish to consider looking at these areas for replacement. My laptop has a lowest rating of 4.3, which is more than adequate, but should one number be low compared to the rest, I would consider replacing that element. If your computer is running low on RAM, for example, it will use the hard drive as an extension of memory, but this deals a fatal blow to your computer’s performance because the hard drive can be 1,000 times slower than memory. In my experience, a Windows Vista PC with just 1GB of memory will struggle unless your system is only lightly used. Read More»

Six Things to Consider Before Buying a Laptop

August 19, 2008 by Jason
Laptops are complex little machines with a variety of configuration options which can lead to very confusing buying decisions. In this article, we are going to cover out factors that one should consider before purchasing a laptop. These 6 factors are the crux of any laptop purchase and by using these as a guideline, you can land the most appropriate mobile PC for your needs.
1- Weight
The lighter the laptop, the easier it is to move around. Prices usually have an inverse relationship with the weight of a laptop. Hence the lightest of laptops will almost (always) cost more than the heaviest ones.
Another relationship is the features of a laptop which would affect the weight of the laptop, which can be if it has a powerful graphics card, or a larger screen etc. The laptop will end up being comparatively heavier and more expensive. So keep a look out for that.
2- Power Consumption
Battery life is critical for users who are on the go. On an average workload, a regular low budget laptop would easily give you 2.5 to 3 hours of battery time. A fairly good machine would easily clock in 4 hours. Read More»

Modding Your Laptop Graphics Card Drivers

August 17, 2008 by Jason
Whenever you play computer games that utilizes 3D graphics, a decent frame rate of about 25-30 frames per second is a prerequisite to make the games run smoothly and be at all enjoyable. If you play on a desktop PC, you always have the option to put in a more powerful graphics card, but that’s not an option with laptop computers. Another problem with laptops – but one that can be avoided – is the lack of updated graphics card drivers. Using updated drivers can provide better performance in new games thanks to game-specific fixes and improvements.
The Problem with OEM Drivers
Although both of the leading graphics card manufacturers (ATI/AMD and Nvidia) provide generic driver updates regularly that are designed to work with all of the respective manufacturer’s chips – even the laptop versions – most OEMs (laptop manufacturers) do not allow these to be installed on your laptop, since they prefer to use proprietary solutions for all their driver updates. As a result, you may be forced to use drivers that are as old as your laptop if the OEM doesn’t update their drivers on a regular basis, which is unfortunately often the case. Read More»

How to identify if you’re CRT Monitor Should Be Replaced ?

August 15, 2008 by Jason
Don’t take that computer monitor in for repair! Often, it is no longer cost-effective to do so. While you or your budget may or may not agree with these tips, it could give you more peace of mind. And help with deciding if and when that old CRT (tube) computer monitor should be retired. You may be surprised to know, a CRT type of computer screen is a more durable option if children or schools will be using it. They often have more life in them.
Necessary Things: CRT monitor, Scissors, Fountain pen, Cable
1. Push the button on the front of the monitor to turn on the monitor if it is not powered on. You might hear a slight buzz sound and see the screen flicker. Wait for Microsoft Windows to load.
2. In the case you do not see a picture, repeat the procedure. If it is flashing in any color other than green you may have a problem. Otherwise, give it time to warm up. Read More»

Hardware Restrictions In Vista

August 11, 2008 by Jason
Vista lets you place restrictions on hardware devices to protect against data theft. You can place restrictions on device installation, limit access to devices already installed and control Autoplay settings for removable devices.
Data theft can occur through the installation of hardware such as removable storage devices. For example, an attacker can install a removable device on your computer with the intent of copying your data to it.
Vista protects against this type of data theft through device installation restrictions. You can control the installation of devices through the local computer policy (or a group policy). You can find these settings in the following container:
Computer Configuration \ Administrative Templates \ System \ Device Installation \ Device Installation Restrictions.

More Information Than You Need…

August 04, 2008 by Jason
We’ve mentioned hardware information utilities a couple of times in the past, these are programs that tell you about your computer and its setup, but this freeware tool, called HWiNFO32, leaves absolutely nothing to the imagination. If it were technically possible to tell you how many nuts and bolts are holding your PC together, it would do so. As it is you’ll just have to be content with every possible scrap of information regarding the hardware connected to your computer that it is possible to extract, from the manufacturer’s code name for your CPU chip, to whether or not your monitor supports an obscure feature called Blank to Black Setup. You can also set a benchmark, so you can track performance and monitor changes, there’s a Sensor page, that tells you all about the temperatures and voltages running around inside your machine, and you can save Reports, which might come in handy one day, if you need to track down a tricky fault.
