Adjust Graphics for Speed

Windows XP has a lot of new cool looking visual elements, however, those new elements take up more RAM and cause your computer to be less responsive. By tweaking your graphics settings, you can increase the performance of your computer.

To get started, Let's reduce the color quality.  This setting determines how many colors are displayed on your screen.

     1. Right click on your desktop and select properties.
     2. Click on the settings tab and adjust the color quality drop down box to Medium (16 Bit).
     3. Click OK.

Next, let's use the windows performance settings to optimize your computer for performance.  This will revert back to the old Windows 2000 look as well as take away a lot of the fancy graphics effects.  However, if you are really into performance, this is the price you have to pay.

     1. Right click on the My Computer icon on your desktop or in your start panel and select properties.
     2. Next, Click on the Advanced tab and hit the setting button under performance.
     3. On the visual effects tab, select Adjust for Best Performance and hit OK.
     4. Hit OK once more to exit system properties.

Disk Defragmenter for Optimizing the Placement of Files.

This utility program is used to re-organize the files and un-used space on the hard disk, so that operation system can access data more quickly and easily. When operating system stores data on the disk, it stores the data in the first available sector on the disk. In this case data of a file is stored on disk in a scattered form; it is referred to as “File is fragmented”. The fragmentation slows down the data accessing speed of computer. You can improve the performance of your computer by de-fragmenting your hard disk. In De-fragmentation process, the data of each file is stored in continuous sectors. There are many third party software’s available in market for this purpose but you can use windows built-in utility program called Disk Defragmenter. To start disk defragmenter utility, first make sure all running program are closed.


To run disk defragmenter utility, go to the Start button and type dfrg.msc in Run option then press ok. Now here a disk defragmenter window will appear. Select any drive and press defragmenter button. If you have a large hard disk, this process can take several hours. I recommend you doing this after one month if you want to improve the performance of your computer.

Tips about Fiber Optic

Learn more about Fiber Optic

A fiber optic cable consists of tubes of glass or plastic fiber which transmit digital data over longer distances and at higher data rates than other forms of wired and wireless communications. A typical optical fiber consists of a very narrow strand or fiber of glass called the core. This core is surrounded by a concentric layer of the glass called cladding. The diameter of a core is 62.5 microns and the diameter of cladding is about 125 microns. The cladding is coated with insulating material such as plastic jacket.

In twisted-pair cable and coaxial cable, data is transmitted in the form of electric frequencies. So copper wire has to be protected from water and electromagnetic waves. In fiber optic cable, these types of problems are not occurred.

The data transmission speed is very high because fiber-optic cable uses light to transmit data. The data transmission speed is up to billions bits per second. An important characteristic of fiber optic is refraction. Refraction is the characteristic of a material to either pass or reflect light. When light passes through a medium, it bends as it passes from one medium to the other.

The advantages of fiber optic cable are:

* Its transmission capacity is about 26,000 times greater than twisted pair media - up into the gigabits and more reliable (lower data transmission errors).

* It has high level of security and much thinner and lighter than other metal wires.

* Fiber optic not affected by electromagnetic noise for example radios, motors and others cables.

The disadvantage of fiber optic is that the cables are very costly and difficult to install.

Therefore the fiber-optic cable is becoming more popular and replacing all old cable system. Today telephone, banks, and television companies are replacing their existing telephone and coaxial cables with fiber-optic cables.

Graphic Card Troubleshooting

The graphic card is one of the most important pieces of hardware in your PC. Without it, your super monitor with all the bells and whistles is just a junk box.

Make Directional Input

Most video cards come with simple frame capture programs, but you'll have to do some programming if you plan to integrate video capture with other operations on your computer, such as adding text data as an overlay or changing video-in channels on the fly. In this case you'll need good programming libraries in a language with which you are familiar for the video card. Some companies include libraries with their cards, but most charge extra. Most often libraries, when available, are for C or BASIC, and sometimes Pascal.

Choose Between 24 bit and 32 bit

For True Color mode, some graphic cards offer 24 bit while some offer 32 bit. Which is the best? When True Colour mode was first suggested, it utilizes 32 bit which was very pleasing to the eye, they realize that 24 (with less coolers) won't look much different since the human eye can only take about a certain amount of colors. On the other hand, 24 bit will run faster compared to 32 bit because it uses less colors. So if your card utilizes 24 bit, don't worry, it isn't bad.

Always Use The Latest Drivers

Yes, it is important to make sure you always have the latest drivers. The latest drivers will offer you better performance, more utilities and more compatibility (usually for DirectX or Direct3D). Take the effort to check you card manufacturer's site to look for the latest driver updates.

Boot or Start Computer Faster

Many computers take a lot of time to boot (or start). This is due to many reasons.

Some slight changes can do wonders for your system:

1. Press start->run then type msconfig and press enter.

Go to the Startup tab. Here you will see a list of Startup items. These are all the programs that automatically start when you boot your PC. It is these that slow down the boot up process.

So uncheck all the unwanted items like ms-office, messengers other utilities that u may not need at startup). Don't uncheck your antivirus software.

Restart your PC to and see for yourself, your PC will now boot faster....

2. A great new feature in Microsoft Windows XP is the ability to do a boot defragment. This places all boot files next to each other on the disk to allow for faster booting. By default this option is enabled, but on some systems it is not, so below is the information on how to turn it on:

Go to Start Menu and Click Run
Type in regedit then click ok
Find "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Dfrg\BootOptimizeFunction"
Select "Enable" from the list on the right
Right on it and select "Modify"
Change the value to Y .
Reboot your PC and see the change yourself.

3.SPEED UP BOOT BY DISABLING UNUSED PORTS.!!
You may have tried many tweaks like modifying windows XP start-up applications, prefetches, unload DLLs method, etc. And yes those methods do work for me.

I have just accidentally found out another way to give you an extra boost in windows XP's boot performance. This is done by disabling your unused devices in Device Manager. for example, if you don't have input devices that are connected to one of your USB's or COM ports, disabling them will give you an extra performance boost in booting. Go to Control Panel -> System -> Hardware tab -> device manager Disable devices that you don't use for your PC and then restart.

Windows Vista Hardware and Software Requirements

According to Microsoft Corp, computers capable of running Windows Vista are classified as Vista Capable and Vista Premium Ready.

A Vista Capable or equivalent PC needs to have at minimum an 800 MHz processor, 512 MB RAM and a DirectX 9 class graphics card. A computer that meets these requirements will be capable of running all editions of Windows Vista although some of the special features and high end graphics options may require additional or more advanced hardware.

A Vista Premium Ready PC will take advantage of Vista's "high-end" features but will need at least a 1.0 GHz processor, 1 GB main memory, and an Aero-compatible graphics card with at least 128 MB graphics memory and supporting the new Windows Display Driver Model. The company also offers Windows Vista Upgrade Advisor from its website to determine the ability of a PC to run Vista in its various guises. The utility runs on Windows XP (with Service Pack 2) and Windows Vista.
Microsoft lists some Vista capable hardware on their website. The "Windows Vista Premium Ready" laptops they specify have Intel Core 2 Duo T5500 or above CPUs and 1 GB memory.

Windows Vista's "Basic" and "Classic" interfaces will work with virtually any graphics hardware that supports Windows XP or 2000; accordingly, most discussion around Vista's graphics requirements centers on those for the Windows Aero interface. As of Windows Vista Beta 2, the NVIDIA GeForce FX family and later, the ATI Radeon 9500 and later, Intel's GMA 950 integrated graphics, and a handful of VIA chipsets and S3 Graphics discrete chips are supported.Though some XGI Technology Volari chips were DirectX 9 (including the Volari V3XT which was available in PCI cards), with XGI's exit from the graphics card business it appears none of its chips are supported as of Vista Beta 2. A PCI Express (PCIe) video card is not a requirement for Windows Aero, but Microsoft recommends PCIe video over an AGP device due to the interface's greater bandwidth. There are some PCI cards available that are compatible with Windows Vista as well.
