How to Restore Registry from Backup File?

After we backup registry by creating a file, it is no use doing this without knowing how to restore registry from the backup file. We can do it in a very easy way by using Import command which is in the Regedit Software. (If you don’t know how to create the backup file, Please Read “Backup Registry …“.)

Open Regedit Software. Know how to do, please read “Edited Windows Registry Tool …” .
Click on File > Import
Choose the registry backup file which is in dot reg (.reg) format.
Then click Open.
Now the registry is recovered from your backup file

However, we can restore the registry in another way. If your backup file is in dot reg (.reg) format, you do not need to open Regedit software for registry recovery. You just double-click on the backup file and then click “Yes”.

Driver for Windows Vista

Windows Vista is Microsoft’s new generation of graphical operating systems used on personal computers. It is designed to host both managed and native applications on a productive and secure platform. Compared to its predecessor Windows XP, Vista has numerous new and reworked features which make it more reliable, secure, and powerful.

Windows Vista does not use drivers that the user specifies during installation for the storage device. Since Windows Vista does not support a number of older hardware and software, it generally requires an update or new driver to operate smoothly and efficiently.

As far as Window Vista installation is concerned, it can be done with the help of a Windows Vista installation disc. While installing this operating system, the user requires using advanced settings in the Window Vista Setup to specify the storage device driver.

The storage driver which the user specifies during Windows Vista installation is loaded during the overall scenario. It only supports the drivers present in its installation disc.

Storage device features for the driver that the user specifies while installing the operating system are not available in Windows Vista. It will not show them even though Vista appears to use the .inf file which matches to the storage device driver the user specifies during installation.

To resolve the problem, the user requires loading the specific driver again. Outlined below are the required steps to complete the task:

* Insert the Windows Vista Installation Disc into the CD/DVD drive.

* Reboot the computer from the installation disc.

* Insert the media which has the new storage device driver.

* Configure the Windows Vista Setup program using the advanced settings.

Note: The user needs to click Load Driver to load the particular driver from the media. This will configure the Windows Vista Setup Program to use the specific driver.

Indeed, the drivers implemented for Microsoft Windows XP and Microsoft Windows Server 2003 may lead to technical default in Microsoft Windows Vista operating system. This is why when it comes to reliability of the Windows Operating System, the Microsoft is always the brunt of much criticism.

Overclock Your Computer

There are two schools of thought as to why you can, or would even want to overclock most CPUs and GPUs. One of them takes the peace, love and understanding route, namely that the manufacturing process is never 100 per cent reliable, so not every chip that rolls off the same production line is born equal. Those with the most lustrous coats and shiniest eyes (bred on Pedigree, presumably) are ready to be high-end components, but those with a bit of a squint and a runny nose may have a funny turn if they exert themselves too much.

Hence, some chips are slapped with a lower official clock-speed and sold for less groats than their beefier brethren. The potential for their intended glory remains, however. Overclocking techniques can unlock at least some of that potential, albeit at the risk of frying the chip completely.

The tinfoil hat/Angry Internet Men theory is based on the same concept but chucks in a bit of paranoia. In this scenario, every same-series processor is born equal, but The Man artificially neuters most of them and slaps different badges on what are fundamentally the same chips. Overclocking, then, is simply a way of taking back what's rightfully yours.

The truth likely lies somewhere between the two. Mass production certainly makes more financial sense than dozens of separate lines, and it's true that a low-end CPU or GPU can be made to punch far above its weight, but their stability isn't as guaranteed as a chip that's officially able to run at a higher speed. No manufacturer wants to deal with a steady trickle of returned parts, after all. But it does mean home overclocking is almost always productive - and seemingly more so with every new hardware generation.

It's also increasingly easy. The earliest overclocking on the 4 to 10MHz 8088-based CPUs of 1983, involved desoldering a clock crystal from the motherboard and replacing it with a third-party one, with only partially successful results. Ouch. Still, the precedent was set: a dedicated guy-at-home could exceed his chip's official spec. IBM, then very much the top dog of PC land, wasn't entirely happy about this, so follow-up hardware included hard-wired overclock blocks.

More soldering this time of a BIOS chip, managed to get around this. By 1986 IBM's stranglehold had been broken, resulting in a raft of 'clone' systems - and a wealth of choice. Intel's 286 and 386 processors became the de facto standard chips, and bus speed and voltage controls began to shift from physical switches and jumpers to BIOS options and settings.

It was the 486 that really changed everything however. It's telling that this was the chip most prevalent during the era that birthed the first-person shooter as we know it: 1993's Doom very much popularized performance PCs for gaming driving system upgrades in the same way a Half-Life 2 or Crysis does these days. At the same time, the 486 introduced two concepts absolutely crucial to overclocking both then and now. Firstly, it popularized split product lines; no longer was it a matter of buying simply a processor, but rather which processor. The 486SX and DX offered some serious performance differential, and notably the SXs were hobbled/failed DXs, giving rise to the ongoing practice of assigning different speeds and names to what were the same chip.

For a while too, the 25MHz SXes could be overclocked to 33MHz by adjusting a jumper on the motherboard; something less salubrious retailers took full advantage of. Secondly, it introduced the multiplier: performing more clocks per every one mustered by the system's front side bus. The 486's 2x multiplier thus effectively doubled the bus frequency. This was something overclockers would make the best of for successive processor generations - bumping up the multiplier was the simplest and often most effective way of increasing CPU speed. Nowadays (since the Pentium II, in fact), the multiplier is locked to prevent this, save for high-end chips, such as Intel's Extreme Edition series. For a while, there were complicated ways of defeating the multiplier lock: soldering on a PCB for earlier chips, third-party add-ons and the infamous practice of drawing a line onto certain AMD CPUs with a pencil. No CPU manufacturer's likely to make that mistake again.

Around this time, RAM overclocking became more common place, as memory speeds were ratified, and with that came more tweaking of the front-side bus to compensate for the locked multipliers. Overclocking shifted further towards the BIOS and away from jumpers, which in turn led to overclocking software.

The first was 1998's SoftFSB, which enabled bus-tweaking from within Windows for the first time. With the Pentium III era came aftermarket coolers, as processors now chucked out so much heat that a standard cooling block and fan wasn't enough to cope with an overclocked chip. And so it continued, overclocking largely becoming easier and more common place with each processor generation. This leads us to the Core 2 chips of today, and Intel's current terrifyingly unassailable dominance of the CPU market. Generally drawing as little as half the power of the Pentium 4s that preceded them, most of the range offers a vast amount of overclocking headroom, to the point that a low-end Core 2 Duo can almost go toe-to-toe with the top of the line.

So how's it done? Key to processor overclocking is the front side bus (FSB). In the very simplest terms, this is the connection between the CPU and the rest of the PC, and its speed defines the processor's speed to a significant extent. Intel CPUs final speed is the FSB times the multiplier - so if you've got an FSB of 266MHz and a multiplier of 9, your chip will run at approximately 2.4GHz. While the multiplier is usually locked - though some chips let you at least lower it, to conserve power and reduce heat - the FSB isn't. Bump up the FSB and you bump up the chip. In our example taking the bus to 290MHz gives us a 2.6GHz processor. This is no random example, incidentally, it's what we run the Intel Core 2 Quad Q6600 in one of our office test systems at, giving it a healthy 200MHz boost that makes a noticeable difference in CPU-intesive games and hi-def video re-encodes.

What stops us from going higher? Not a lot in the case of this particular chip. We're playing it safe for desktop work, cos we're in a particularly sweaty office. When we're playing around with high-end tasks, we can have it running stably at over 33GHz (with an FSB of 370 or so) on a decentish, third-party air cooler. That's more or less trading blows with the best Intel has to offer on a $200 chip. But while going to 280MHz on the FSB took a BIOS tweak, a reboot and Microsoft BOB's your uncle, going much higher does involve more fuss.

First up, when our Q6600 is at 33GHz, it's also running at nearly 70°C when under maximum load (and around 50°C when idling). It's perfectly stable, but it could damage it in the long run, and on top of that the fan is making enough noise to wake the deaf pensioner in the next street over. Watercooling, a fancier air-cooler or even just a spot of dust-cleaning will bring the heat down, but there can come a point where that stuff becomes more expensive and hassle than simply buying a better processor.

Hurdle the second is the motherboard. Pushing up the FSB doesn't affect only the CPU, but also the motherboard and, in many cases, the RAM and PCI-e slot to boot. In our case, we're using a motherboard that supports a monstrously high FSB. When shopping for a motherboard, its max FSB will usually be referred to as four times the actual speed, due to the way the processor actually fetches data. So when we've got the FSB set to 266MHz, in effect that's 1,066MHz. When it's up to 372MHz, we need a motherboard that's happy at nearly 1,500MHz. That simply isn't a given, especially on cheaper boards, so shop carefully.

As well as that, if you've got a board with a stingy BIOS, you may not be able to alter RAM and PCI timings independently of the FSB, which can lead to those falling over. Ours does, and for our mighty near-Gigahertz Q6600 overclock, we have to lower the RAM's clock speed a little to compensate for the strain put on it by the raised FSB - we have it sitting pretty at 893MHz. It could comfortably go higher, but the real-world benefits (as opposed to the willy-waving benefits, which are a different matter entirely) would be so miniscule that it's simply not worth placing the extra pressure on the RAM.

Similarly, while faster and, most likely, more expensive RAM will cope better at their stock speeds with a massive FSB, the pay-off is often so minor that value RAM, running at a lower clock-speed may well be enough to make your overclocking masterplan hugely successful. Even the best memory will net you something in the region of just a five per cent performance boost - worth having if every little helps, but it's the FSB that makes the big difference. And for that, the motherboard is critical.

Thirdly, there's the matter of voltage. The faster your chip runs, the more power it needs to feed it. As the FSB goes up, you'll find your motherboard's North Bridge and your RAM also get hungrier.

Unfortunately, your hardware will automatically report its revised power requirements, so trial and miserable error are required to find the sweet spot. Volt tweaking is a fiddly and danger-fraught business.

Some overclocking-friendly motherboards can automatically adjust voltages for you, but are understandably conservative about it, so for the really big overclocks you'll need to set them yourself. This needs to be done by the tiniest increments possible, establishing reboot-by-reboot how many volts your embiggened CPU needs; as low as possible, essentially, as firing too many into it can fry it.

Establish in advance what your chip's out-of-the-box volts are and, through a mix of common sense and googling, decide on a number you're not going to risk going higher than. We pushed our Q6600 from 13 to 1.4V, which is a fairly big increase as volt modding goes. It's not just a matter of the so-called vCore either - as you go for the big overclocks, you'll find you're having to play with the arcane likes of CPU PLL and FSB termination voltage. Again, so long as you raise stuff in tiny increments the risk of killing your chip, RAM or motherboard is fairly minimal.

It's a different matter with AMD processors, which for a while now have had an onboard memory controller, which allows the chip to communicate more directly with the RAM, which in turn means there isn't an FSB as such. Instead, you're overclocking something known as the HyperTransport bus, which is achieved in more or less the same way, but can require lowering the NT's own multiplier to retain stability when you bump the speed. If you've gone for one of the recent AMD Phenom Black Editions, you'll find it comes with the multiplier unlocked, which makes overclocking an easier affair.

By contrast, overclocking a graphics card is dead simple. As a more self-contained piece of hardware, there's none of this confusing multiplier or FSB business; just overclocking the card itself, finding the right speeds for both the GPU and the card's onboard memory. Free software - some of it official NVIDIA/ATI driver plug-ins - will do the trick from within Windows, and built-in safety cut-offs and stability tests make it incredibly hard to damage the card, though of course you are going beyond the warranty.

It's also grown a little more complicated of late in that you may need to overclock the shader clock as well as the GPU and RAM for the best boosts. In the case of NVIDIA cards, it used to be that this was twinned to the GPU speed, meaning a raise in one had a synchronous effect on the other, but for a little while now they've been able to be altered independently. So if you hit the speed ceiling on the GPU, it may yet be possible to eke more performance out of the card by pushing the shader clock a little further.

While the present situation is that you can overclock everything and be pretty confident it'll work, the future of the form is harder to call. One thing seems sure: it's not a dirty little nerdy secret anymore, but an increasingly common practice, most especially with Core 2 chips. There's a vast aftermarket cooler industry to support it, and even cheap motherboards can handle a bit of a free boost. If anything overclocking will become easier, with more and better applications to achieve it within Windows, rather than from the BIOS, and possibly more in the way of automatic volt-modding. But much depends on the future of desktop processing. There's a big war brewing between Intel and NVIDIA as to whether the CPU or the GPU will be the major element in the PC of the near-future.

Intel are pushing ray-tracing using a multi-core CPU to render game graphics, while NVIDIA's CUDA enables its recent GeForce cards to perform parallel processing, such as video encoding and in-game physics, far faster than a CPU could manage. If either of these bed in, overclocking will need to take them into account. At the same time, the slow move to ever-more cores potentially reduces the need for conventional overclocking, as raw clock speed continues to be a lesser concern to multi-threading and, in the case of 3D cards, the number of stream processors and texture units. That's hardly going to stop anyone from trying it, of course. Even when its effects are minimal, overclocking's always going to be a sure-fire way of making a system feel like its yours rather than simply a collection of mass-produced parts.

Modding the case is one thing, but what makes a PC is its performance. When you've painstakingly tweaked that performance into something that suits your own purposes, and it's become something that feels like you've gone far beyond what you paid for it, the system will feel more unique than all the green neon tubing in the world could ever hope to achieve.

Buy Quality Computer Hardware Online

Computer hardware means the physical part of a computer. No software or program can do anything without proper hardware. Moreover the success or performance of a software program depends completely on the computer hardware being used. So it becomes absolutely important that we buy quality computer hardware.

Now that you have decided to buy computer parts, the next big step is where to buy them from. One tends to always buy from a friendly neighborhood computer hardware dealer. But, with the advent of Internet, one has the convenience of going through literally hundreds of product catalogs and arriving at a purchasing decision.

The Internet is a popular place to check out computer hardware sales, but you must be sure that when you buy hardware (or any purchase) over the Internet, the site offers some kind of security to prevent information about you from being stolen.

Buying a computer part online is often cheaper than buying it from a dealer, as the overhead costs are reduced. This means that you pay less and get more. This is one advantage that has led people in increasing numbers to shop for parts online, especially from a wholesaler. Since the entire sales channel is literally cut in half, you do not pay for the extra margin, which you would have had you purchased the same from a retailer. There is also the convenience factor of shopping online.

In fact, cheap and discount computer hardware is very easy to find online. Whether it is notebook parts, input devices, printer, printer supplies you can find them extensively advertised and sold online.

One should always take care to ensure that the parts that one is buying are genuine. What this means is that one should always buy these computer hardware from a reputed online dealer.

Types of Computer Hardware

Computer hardware is a physical part of a computer that executes within the hardware. It is unlike computer software or data that can be frequently changed, modified or erased on a computer. Computer hardware is not frequently changed and so is stored in hardware devices such as read only memory (ROM) where it is not readily changed.

Most computer hardware is embedded and so is not visible to normal users. Below are the different types of hardware's found in a computer:

Motherboard: It is the central or primary circuit board making up a complex electronic system such as a computer. A motherboard is also known as a main board, logic board or system board.
Central processing Unit: A CPU is the main component of a digital computer that interprets instructions and process data in computer programs.
Random Access Memory: A RAM allows the stored data to be accessed in any order. RAM is considered as the main memory of the computer where the working area is used for displaying and manipulating data.
Basic Input Output System: BIOS prepares the software programs to load, execute and control the computer.
Power Supply: Power Supply supplies electrical energy to an output load or group of loads.
Video Display Controller: It converts the logical representation of visual information into a signal that can be used as input for a display medium.
Computer Bus: It is used to transfer data or power between computer components inside a computer or between computers.
CD-ROM drive: It contains data accessible by a computer
Floppy disk: It is a data storage device
Zip Drive: It is a medium capacity removable disk storage system.
Hard Disk: It is a non-volatile data storage system that stores data on a magnetic surface layered unto hard disk platters.

RAM Upgrade: How Much Is The Best For Your Computer

The gainful process for upgrading the computer is addition of RAM that will speed up the running of the slothful computer. The computers will be purchased with more than sufficient RAM. But after some years this will become insufficient due to the new programmers that crop up. More memory power is required for the latest operating systems. When a computer has insufficient RAM, it changes the spill over data very often from the hard drive and thus reduces the performance of the computer.

There may be various reasons for the slow performance of a computer. One among them is the RAM capacity. It is advised to check up the RAM immediately when the computer breaks down. How can the requirement of RAM be verified? It is very simple. Just go to the windows task manager and then press Ctrl+Alt+Del to go to the performance tab. The vista users should just click start task manager. If the figure indication is zero next to Available in the case of windows and Free in the case of Vista, then it is a must that the RAM has to be upgraded.

In general, 1 GB RAM is quite sufficient for the users of average Windows XP. The computer that is utilized for running programs like functioning with images and burning of CD’s with Nero Express programme will have a better speed with 1 GB RAM than the 512 MB RAM. But a minimum of 2 GB RAM is required for those users who utilize the computer with the programmers to work with the huge graphic files or digital video. Here again, it is recommended to have 2 GB RAM for a better performance for those computers which are to be upgraded to windows vista.

There are various types of RAM available in the market. Some of them are DDR, DDR2 and DDR3. Those RAM which are produced with the new technology will definitely have a fast performance. But, in general almost many mother boards do accept only one kind of RAM. Hence, it is a must for the user to check up the manual of the computer regarding the type of the RAM that can be installed and its procedure before finalizing the capacity of the RAM and its type. There are also various online equipment available to get the information handy regarding the usage of the type of the RAM in the computer.

Many of the computers that are upgraded now use mostly the dual channel memory. This is mainly due to its extreme good performance. Thus the preference now goes to install two numbers of 512 MB RAM than one number of 1 GB RAM. Here again, the documentation has to be checked before taking up the installation work of RAM. It is also safe to buy quality product without minding paying of a little higher cost rather than going for an inferior quality.

Troubleshooting and Maintaining Your Laptop Battery

Troubleshooting and Maintaining Your Laptop Battery

The actual life of a laptop battery will vary with computer usage habits. For most users, it is not uncommon to experience differences in battery life, of anywhere from just under one hour to over two hours in each sitting. If you are experiencing shorter battery life cycles, say 10 to 15 minutes, it may not yet be time to order that new battery.

There are several factors to take into consideration when determining if the time has come to replace your battery. This information may also apply to that new battery that you have recently purchased, that has been giving you fits. The two primary things to consider when troubleshooting battery problems is Usage Habits and Battery Memory. We will cover both in their complexities in just a moment, but first, let us take a look at what you should expect from your battery's life cycle.

NiMH batteries usually last 1.5 to 2.5 hours.
LiION batteries usually last 2.0 to 3.0 hours.

These are average results and the results will vary greatly depending on your system's conservation settings, the temperature of the room and the climate that you are operating your computer in. As a general rule, your Lithium Ion battery will last much longer than your standard Nickel Metal Hydride battery.

Now let's take a look at the various usage habits to consider when troubleshooting your laptop's battery. These processes are very similar to the way that your portable stereo uses batteries ... just think how much faster your stereo dell Inspiron 9400 battery eats batteries when you are playing the CD or the tape deck, as opposed to when you are just playing the radio.

The more you use physical devices --- which require more electricity to operate --- the more of the battery's power you can expect to consume. The devices that create a larger power drain are the hard drive, the floppy drive and the CD-ROM.

When the computer dell 310-6321 battery is able to use its physical memory resources to store information, the computer will use less of the battery's power, since the process is mostly electrical in nature. However, when the processes you are using exhaust the physical memory resources available to your system, the system will turn to virtual memory to continue the process at hand. Virtual Memory is designed to extend system memory resources by building a memory swap file on the hard drive, and then transfer needed information between the hard drive and the physical memory as required. Since the hard drive is a electricity hog, the use of virtual memory becomes an electricity hog by proxy.

Two other processes that engage virtual dell 310-6322 battery memory on your computer are computational programs and the calculation processes used by spreadsheet applications and database programs. Both of these items engage the processor to a greater degree as well, which in itself is a consumer of electricity. Because they both compute and calculate large quantities of information, they will also increase the amount of electricity that your laptop will consume.

Computer Tips : 23 Easy Ways To Speed Windows Xp

Computer Info, Tips and Tricks about the Operating System.. (Windows XP)

Since defragging the disk won't do much to improve Windows XP performance, here are 23 suggestions that will. Each can enhance the performance and reliability of your customers' PCs. Best of all, most of them will cost you nothing.

1.) To decrease a system's boot time and increase system performance, use the money you save by not buying defragmentation software -- the built-in Windows defragmenter works just fine -- and instead equip the computer with an Ultra-133 or Serial ATA hard drive with 8-MB cache buffer.

2.) If a PC has less than 512 MB of RAM, add more memory. This is a relatively inexpensive and easy upgrade that can dramatically improve system performance.

3.) Ensure that Windows XP is utilizing the NTFS file system. If you're not sure, here's how to check: First, double-click the My Computer icon, right-click on the C: Drive, then select Properties. Next, .. examine the File System type; if it says FAT32, then back-up any important data. Next, click Start, click Run, type CMD, and then click OK. At the prompt, type CONVERT C: /FS:NTFS and press the Enter key. This process may take a while; it's important that the computer be uninterrupted and virus-free. The file system used by the bootable drive will be either FAT32 or NTFS. I highly recommend NTFS for its superior security, reliability, and efficiency with larger disk drives.

4.) Disable file indexing. The indexing service extracts information from documents and other files on the hard drive and creates a "searchable keyword index." As you can imagine, this process can be quite taxing on any system.

The idea is that the user can search for a word, phrase, or property inside a document, should they have hundreds or thousands of documents and not know the file name of the document they want. Windows XP's built-in search functionality can still perform these kinds of searches without the Indexing service. It just takes longer. The OS has to open each file at the time of the request to help find what the user is looking for.

Most people never need this feature of search. Those who do are typically in a large corporate environment where thousands of documents are located on at least one server. But if you're a typical system builder, most of your clients are small and medium businesses. And if your clients have no need for this search feature, I recommend disabling it.

Here's how: First, double-click the My Computer icon. Next, right-click on the C: Drive, then select Properties. Uncheck "Allow Indexing Service to index this disk for fast file searching." Next, apply changes to "C: subfolders and files," and click OK. If a warning or error message appears (such as "Access is denied"), click the Ignore All button.

5.) Update the PC's video and motherboard chipset drivers. Also, update and configure the BIOS. For more information on how to configure your BIOS properly, see this article on my site.

6.) Empty the Windows Prefetch folder every three months or so. Windows XP can "prefetch" portions of data and applications that are used frequently. This makes processes appear to load faster when called upon by the user. That's fine. But over time, the prefetch folder may become overloaded with references to files and applications no longer in use. When that happens, Windows XP is wasting time, and slowing system performance, by pre-loading them. Nothing critical is in this folder, and the entire contents are safe to delete.

7.) Once a month, run a disk cleanup. Here's how: Double-click the My Computer icon. Then right-click on the C: drive and select Properties. Click the Disk Cleanup button -- it's just to the right of the Capacity pie graph -- and delete all temporary files.

8.) In your Device Manager, double-click on the IDE ATA/ATAPI Controllers device, and ensure that DMA is enabled for each drive you have connected to the Primary and Secondary controller. Do this by double-clicking on Primary IDE Channel. Then click the Advanced Settings tab. Ensure the Transfer Mode is set to "DMA if available" for both Device 0 and Device 1. Then repeat this process with the Secondary IDE Channel.

9.) Upgrade the cabling. As hard-drive technology improves, the cabling requirements to achieve these performance boosts have become more stringent. Be sure to use 80-wire Ultra-133 cables on all of your IDE devices with the connectors properly assigned to the matching Master/Slave/Motherboard sockets. A single device must be at the end of the cable; connecting a single drive to the middle connector on a ribbon cable will cause signaling problems. With Ultra DMA hard drives, these signaling problems will prevent the drive from performing at its maximum potential. Also, because these cables inherently support "cable select," the location of each drive on the cable is important. For these reasons, the cable is designed so drive positioning is explicitly clear.

10.) Remove all spyware from the computer. Use free programs such as AdAware by Lavasoft or SpyBot Search & Destroy. Once these programs are installed, be sure to check for and download any updates before starting your search. Anything either program finds can be safely removed. Any free software that requires spyware to run will no longer function once the spyware portion has been removed; if your customer really wants the program even though it contains spyware, simply reinstall it. For more information on removing Spyware visit this Web Pro News page.

11.) Remove any unnecessary programs and/or items from Windows Startup routine using the MSCONFIG utility. Here's how: First, click Start, click Run, type MSCONFIG, and click OK. Click the StartUp tab, then uncheck any items you don't want to start when Windows starts. Unsure what some items are? Visit the WinTasks Process Library. It contains known system processes, applications, as well as spyware references and explanations. Or quickly identify them by searching for the filenames using Google or another Web search engine.

12.) Remove any unnecessary or unused programs, from the Add/Remove Programs section of the Control Panel.

13.) Turn off any and all unnecessary animations, and disable active desktop. In fact, for optimal performance, turn off all animations. Windows XP offers many different settings in this area. Here's how to do it: First click on the System icon in the Control Panel. Next, click on the Advanced tab. Select the Settings button located under Performance. Feel free to play around with the options offered here, as nothing you can change will alter the reliability of the computer -- only its responsiveness.

14.) If your customer is an advanced user who is comfortable editing their registry, try some of the performance registry tweaks offered at Tweak XP.

15.) Visit Microsoft's Windows update site regularly, and download all updates labeled Critical. Download any optional updates at your discretion.

16.) Update the customer's anti-virus software on a weekly, even daily, basis. Make sure they have only one anti-virus software package installed. Mixing anti-virus software is a sure way to spell disaster for performance and reliability.

17.) Make sure the customer has fewer than 500 type fonts installed on their computer. The more fonts they have, the slower the system will become. While Windows XP handles fonts much more efficiently than did the previous versions of Windows, too many fonts -- that is, anything over 500 -- will noticeably tax the system.

18.) Do not partition the hard drive. Windows XP's NTFS file system runs more efficiently on one large partition. The data is no safer on a separate partition, and a reformat is never necessary to reinstall an operating system. The same excuses people offer for using partitions apply to using a folder instead. For example, instead of putting all your data on the D: drive, put it in a folder called "D drive." You'll achieve the same organizational benefits that a separate partition offers, but without the degradation in system performance. Also, your free space won't be limited by the size of the partition; instead, it will be limited by the size of the entire hard drive. This means you won't need to resize any partitions, ever. That task can be time-consuming and also can result in lost data.

19.) Check the system's RAM to ensure it is operating properly. I recommend using a free program called MemTest86. The download will make a bootable CD or diskette (your choice), which will run 10 extensive tests on the PC's memory automatically after you boot to the disk you created. Allow all tests to run until at least three passes of the 10 tests are completed. If the program encounters any errors, turn off and unplug the computer, remove a stick of memory (assuming you have more than one), and run the test again. Remember, bad memory cannot be repaired, but only replaced.

20.) If the PC has a CD or DVD recorder, check the drive manufacturer's Web site for updated firmware. In some cases you'll be able to upgrade the recorder to a faster speed. Best of all, it's free.

21.) Disable unnecessary services. Windows XP loads a lot of services that your customer most likely does not need. To determine which services you can disable for your client, visit the Black Viper site for Windows XP configurations.

22.) If you're sick of a single Windows Explorer window crashing and then taking the rest of your OS down with it, then follow this tip: open My Computer, click on Tools, then Folder Options. Now click on the View tab. Scroll down to "Launch folder windows in a separate process," and enable this option. You'll have to reboot your machine for this option to take effect.

23.) At least once a year, open the computer's cases and blow out all the dust and debris. While you're in there, check that all the fans are turning properly. Also inspect the motherboard capacitors for bulging or leaks. For offers about discounts:

Following any of these suggestions should result in noticeable improvements to the performance and reliability of your customers' computers. If you still want to defrag a disk, remember that the main benefit will be to make your data more retrievable in the event of a crashed drive.

Top 55 Tips for Search Engine Optimization (SEO)

Here is The Top 55 SEO tips for beginner, newbie, or new webmaster..

Search engine optimization or SEO pertains to the the way you optimize a site in order to improve its ranking in search engine results pages. If you secure a place in the top 10 list of major search engines for keywords or key phrases which are related to you site, more people will visit your site and hopefully, they will convert into customers. SEO involves a lot of different techniques to make sure that the website will be visited by your target audience. With millions of sites in the World Wide Web, it is almost impossible for people to know your site exists if you do not optimize it. It is therefore important to do several SEO techniques to make your site visible to your target market and beat the competition.

In SEO, the goal is to improve site ranking in search engines. When someone looks for something on the net and uses keywords or key phrases that are related to your site, you will want your site to appear on the first page of the search results. There are different SEO methods or techniques that should be done to make this happen. In this article, take a look at some SEO tips for beginners:

If you absolutely MUST use Java script drop down menus, image maps or image links, be sure to put text links somewhere on the page for the spiders to follow.
Content is king, so be sure to have good, well-written and unique content that will focus on your primary keyword or keyword phrase.
If content is king, then links are queen. Build a network of quality backlinks using your keyword phrase as the link. Remember, if there is no good, logical reason for that site to link to you, you don’t want the link.
Don’t be obsessed with PageRank. It is just one isty bitsy part of the ranking algorithm. A site with lower PR can actually outrank one with a higher PR.
Be sure you have a unique, keyword focused Title tag on every page of your site. And, if you MUST have the name of your company in it, put it at the end. Unless you are a major brand name that is a household name, your business name will probably get few searches.
Fresh content can help improve your rankings. Add new, useful content to your pages on a regular basis. Content freshness adds relevancy to your site in the eyes of the search engines.
Be sure links to your site and within your site use your keyword phrase. In other words, if your target is “blue widgets” then link to “blue widgets” instead of a “Click here” link.
Focus on search phrases, not single keywords, and put your location in your text (“our Palm Springs store” not “our store”) to help you get found in local searches.
Don’t design your web site without considering SEO. Make sure your web designer understands your expectations for organic SEO. Doing a retrofit on your shiny new Flash-based site after it is built won’t cut it. Spiders can crawl text, not Flash or images.
Use keywords and keyword phrases appropriately in text links, image ALT attributes and even your domain name.

Power Supply

Description

A computer power supply unit (Computer PSU) is the component that supplies power to a computer. More specifically, a power supply is typically designed to convert 100-120 V (North America and Japan) or 220-240 V (Europe, Africa, Asia and Australia) AC power from the mains to usable low-voltage DC power for the internal components of the computer. Some power supplies have a switch to change between 230 V and 115 V. Other models have automatic sensors that switch input voltage automatically, or are able to accept any voltage between those limits.

The most common computer power supplies are built to conform with the ATX form factor. The most recent specification of the ATX standard is version 2.2, released in 2004. This enables different power supplies to be interchangeable with different components inside the computer. ATX power supplies also are designed to turn on and off using a signal from the motherboard (PS-ON wire, which can be shorted to ground to turn on the PSU outside the computer), and provide support for modern functions such as the standby mode available in many computers.

Webcam

Description

Webcams (web cameras) are small cameras (usually, though not always, video cameras), whose images can be accessed using the World Wide Web, instant messaging, or a PC video conferencing application. The term webcam is also used to describe the low-resolution digital video cameras designed for such purposes, but which can also be used to record in a non-real-time fashion.

Web-accessible cameras involve a digital camera which uploads images to a web server, either continuously or at regular intervals. This may be achieved by a camera attached to a PC, or by dedicated hardware. Videoconferencing cameras typically take the form of a small camera connected directly to a PC. Analog cameras are also sometimes used (often of the sort used for closed-circuit television), connected to a video capture card and then directly or indirectly to the internet.

Computer fan

Description

A computer fan can be any fan inside a computer case used for cooling purposes, and may refer to fans that draw cooler air into the case from the outside, expel warm air from inside, or move air across a heatsink to cool a particular component. The use of fans and/or other hardware to cool a computer is sometimes referred to as active cooling.

LCD Projector

Description

An LCD projector is a type of video projector for displaying video, images or computer data on a screen or other flat surface. It is a modern analog of the slide projector or overhead projector. To display images, LCD (liquid crystal display) projectors typically send light from a Metal halide lamp through a prism that separates light to three poly silicone panels -- one each for the red, green, and blue components of the video signal. As polarized light passes through the panels (combination of polarizer, LCD panel and analyzer), individual pixels can be opened to allow light to pass or closed to block the light. The combination of open and closed pixels can produce a wide range of colors and shades in the projected image.
