CD ROMS – If you’re adding or removing an internal cd-rom, dvd-rom, or just about any internal ROM that has an opening CD door, read on. Almost all IDE devices such as CD-ROM, DVD-ROM, etc. including burners and dvd burners are all installed or removed in the same fashion. If you’re removing your rom, first remove the scrues from both sides of the rom. Make sure both sides are removed or you won’t be able to get the device out. Once the scrues are off, unplug the drive; both the IDE ribbon cable that goes to your mainboard and your power cable. You may also have another wire running from your cd-rom to your sound card. This wire enables sound to play from your rom drive to your sound card, so when you play a cd on your drive you can hear it. Yank all cables running to the drive, then remove it. Simple.
To add a drive, first you must mount the drive in the correct position and remove the IDE bracket on the front of the case. An IDE
There are so many reasons why your hard disk may crashed:
(1) It may be caused by mechanical or physical problem such as the spindle motor system failure. This failure is usually caused by over-heating. The activity light flashing that you see on your CPU (central processing unit) indicates that its head moves to different tracks. If this movement fails, it can no longer read or write data. Remember, a hard disk is a hardware component, not a software. It is a magnetic device use to store data, it reads and writes data as it spins.
(2) Failure of logical system (the logical partitioned drives assigned as C, D, E, F, G) may be caused by and not limited to corrupt system files, corrupt firmware, registry components and virus infection. Spywares, adwares & all other malicious files may also cause your hard disk to crash.
(1) If you see the activity light flashing but the computer does not boot, the case may be, your files is still intact on the hard drive but becomes inaccessible — this may be because
A Silver Bullet?
Until recently, I would have dismissed the notion that electronic gunk can accumulate in a machine and cause it to act erratically. But a few months ago my high-speed Internet connection, which is normally rock solid, started getting flaky. I unplugged my cable modem, plugged it back in and voila… things were back to normal.
And since then I’ve repeated the procedure a few times with good results, whenever I noticed a slowdown in my Internet speed. So I started thinking… maybe electronic devices and appliances really do get tired, clogged with electrons, or whatever. It turns out that there is some good science to support this layman’s observation.
Jerrold Foutz is a Scientist with a capital S. There aren’t many people alive who know more about how electronic gadgets (especially power supplies) are supposed to work. So you might be surprised to hear that when your computer, microwave, VCR or high-tech coffee pot isn’t behaving, his best advice is “just unplug it.”

A look at second-user computer equipment.
Let’s dispense with the myths first. I’m NOT talking about the sort of second-hand computers you get from some high street junk shops, or the sort you can buy from free ads newspapers. These are the types that get used computers a bad reputation since there are many dodgy deals to be had!
I’m talking about a different breed altogether, the sort of used computers you’d be proud to own and feel safe buying because they have proper and lengthy warranties on each and every one of them and have been extensively tested and approved.
The criterion is quite strict. Sure, there are any number of companies out there who offer used computers at low prices. Very few offer 12-month warranties however and many of them disappear just as quickly as they arrived leaving you with a problem. All computers, no matter which category they fit in, or what you call them, should be high quality, guaranteed, fully working computers from a reputable supplier.
So, let’s put all the computers into two categories, I’m going to call them ‘used’ and ‘unused’ computers.
1. Used Computers
* Era without the internet:
In past years, communication from the outside world was not easy, but today, it is made possible using the most useful tools such as the computer and the internet. Some people communicate with their fellows and friends, while some people surf the internet, buy things, and some have adopted making websites as their profession and make it as a part of their business. The Internet allows people to compose, send and receive messages conveniently, and at any time, with ease, they can communicate, rather than visit a post office and write a letter.
* Depth Views about the Internet:
The Internet is a means of connecting one computer to other computers throughout the world using routers and servers. When two computers are connected using the internet, they can share information, like text, graphics, pictures, audio video, and can send and receive messages instantly and with convenience. No one owns the internet; however, several organizations in the world are taking part in this development and functioning. The backbones of the internet are fiber optic cables, which are owned by the telephone companies of the country.
The Internet came out of
To upgrade or not? That is the question. At least, since the release of the new Athlon 64 FX-57, that is the question I have been pondering. Even though the FX-55, (which I am currently running), was everything I had hoped it would be, is the new FX-57 that much better? Well let’s take a look.
The Athlon 64 FX-57 has an increased clock speed of 200 MHz bringing it to 2.8 GHz, up from the 2.6 GHz found in the FX-55. AMD didn’t stop there though, they added a few extras to improve performance.
The chip’s core is actually based on a revised K8 core code named San Diego (1 MB L2 cache), which bring’s the size of the chip’s die down to 90 nm from 130 nm. this is made possible by building the chip on AMD’s latest SOI (Silicon and Insulator) technology.
The FX-57 has an improved memory controller, making it more flexible in terms of allowing you to use different size DIMM’s on the same channel.
So is the FX-57 fast? It’s screaming fast, but is it an enough of an improvement to warrant an upgrade? Well that depends a
Recently, there has been a huge legal and investigative battle with people selling “compatible” laser toner cartridges. Often, a distributor will sell their defective, ineffective, or even damaging laser toner cartridges to unsuspecting resellers. These cartridges will make weak prints, cause messy ink spray, and may cause serious damage to your printer. So be sure to buy cartridges from an authorized reseller that the manufacturer audits. Check the manufacturer’s website to obtain a list of authorized resellers.
Beware of laser toner cartridges that are priced way below market standard. Bad or old packaging should also send up a red flag for phony laser toner cartridges.
Finally, if your cartridge runs out of ink too quickly, gives messy prints, or damages your printer, don’t buy from the same retailer again.
This is not to say that all compatible toner cartridges are bunk. But if you’re going to spend tens of dollars on a cartridge, why risk it?
Remanufactured Laser Toner Cartridges
Most manufacturers, and some third-party distributors, will give you money or discounts in exchange for your old laser toner cartridges. They in turn replace the guts of the cartridge, refill it with toner,
This is the first step to servicing, upgrading or removing PC hardware from your PC. Refer to my other articles on adding, upgading or removing just about any piece of hardware.
First things first, get that case off your PC. This is usually done by removing the screws on the back. Don’t remove the ones near your power supply! This will cause your power supply to fall out. Simply remove the screws along the side that seem to be holding the case to the frame. Usually, this is about 6-9 screws. This will remove both sides. If you are aiming on only removing one side (sometimes this is best, as you only need to service one side) then remove the three screws holding the one side on. (For clone PCs. For IBM/Compaqs, refer below). After you’ve got the screws off either the one side, or both sides, simply slide the sides off towards the front side (the side where the power button is).
If you’ve got an IBM or Compaq, you will need to remove all the screws holding the case onto the back, and then employ one or both methods. Some IBM PCs require you
So you need to check your IP address, for whatever reason. Maybe you’re playing an online game with a friend, or you need to access your PC remotely. Whatever the reason, there are a number of different ways you can check your IP address.
One of the easiest ways is to run an “ipconfig” command in dos prompt. You can access a DOS prompt from windows by hitting start, then run, and typing cmd in the run box. A MS-DOS dialog box will appear. Try typing “ipconfig” in this window.
This will come back with the IP of your computer. However, if you are running a home network or an office network, this will only give you your local IP. This is the IP that has been assigned to you by your router or hub. If you want to check your external IP (which is the one used to connect to your computer or local network) then you need to access your router settings, usually accessed by typing 192.168.1.1 into your browser (or whatever local IP your router has been assigned. Usually, 192.168.1.1 or 192.168.1.0 will be your default gateway IP. “Default gateway IP” meaning your
Many aspects of the personal computer have increased in leaps and bounds in terms of performance and what they are capable of doing.
Computer memory, often referred to as Random Access Memory (RAM), has become of greater and greater performance as time has gone on.
One of the famous quotes from back in the eighties was one made by Bill Gates when he said that no one would ever need more than 640KB of memory. Well that has been passed for ages now, with high performance machines sometimes sporting over 1GB of it.
There are many advantages that can be had with more memory.
- Programs run faster
- Less waiting time for programs to load
- More programs can be run at a time
- Overall computer speed is increased
Double Data Rate (DDR) memory is the staple of the consumer market. It has taken off due to public demand and now comes quite reasonably priced.
Computers don’t generally come with less than 256MB of memory nowadays. My computer after freshly installing Windows 2000 (no, I haven’t gone to Windows XP yet) takes about 80MB or memory. That is the very least, with no additional programs or anything
The big boys in the computer industry want you to continue thinking the way you are. The major desktop computer manufacturers thrive on consumers lack of knowledge and old ideas about desktop computers and computer hardware to drive sales of new desktop computers.
It works in their favor to keep these myths alive, because their business depends on it. So what are they?
Myth 1: You need top of the line computer hardware
Maybe some years ago this might have been true with older computer hardware, but times have changed. When computers were much slower than they are now, the latest version of any computer hardware increased speeds noticeably and allowed new possibilities from your desktop computer.
Those increases from computer hardware no longer yield such a huge increase in performance. With the basic uses of the desktop computer set and been in place for a while now, speed increases no longer result in real world benefits for most desktop computer users.
What was great computer hardware last year is still good enough now.
Myth 2: Computer hardware is the domain of Geeks
When personal computing was coming into its own,
Not so long ago notebook computers were expensive, heavy and reserved for a small portion of computer users, no longer. Today’s notebooks are lighter, less expensive and can be as fully featured as their stuck on your desk counterparts. A little knowledge can be helpful if you are considering making the leap to the convenience of a portable computer.
What are your computer needs? Notebook computers, sometimes referred to as laptop computers, just like desktop computers can be configured for a variety of purposes. Will you be using your notebook primarily for business? If so, are you heavily into word processing or spreadsheets or is your work directed toward graphics? Do you need to be connected to the internet for research and/or communication? Maybe you want a notebook mainly to enjoy games or movies? Make an inventory of your computer use priorities, such a list will help you determine which notebook computer is right for you.
Once you have ascertained what you want out of a notebook computer it’s time to make a list of the options your machine will need.
* Processors and RAM – A 20 gigabyte hard drive and an Intel Pentium
Even an “entry level” computer today usually includes an 80GB hard disk for data storage. But if this is an “entry level” computer, does this suggest that you, as an “experienced” computer user, really need more than 80GB on your hard drive?
Let’s consider what 80GB really translates into. To do this, we will need to make some assumptions. First, let’s suppose your operating system is XP Home Edition, which takes about 2.91 GB of your hard drive. Let’s further suppose you really love to take pictures and use the program, Adobe PhotoShop Elements TM to fix and store them.
This means you should have at least 75 GB left over to store your photos. If you store your photos in the JPEG (.jpg) format, they will probably average about 800 KB each – meaning you should be able to store at least 90,000 photos on that 80GB hard drive.
Here’s another for example. Let’s assume that instead of being nuts about photography, you’re a serious writer and use, as I do, the great, free program OpenOffice.org Writer. In this case, you will need about 3GB for XP and OpenOffice.org, leaving roughly 77GB for your
Personal computers have become relatively inexpensive, at least as compared to what they used to cost. There are now many sources for inexpensive PCs. This article will provide you with information on sources for low-cost personal computers, computer peripherals, and accessories.
The average home computer user does not necessarily need the latest and greatest technology. Most simply need a PC with a relatively new Intel processor, or equivalent; a reasonable amount of memory – 256MB or more; a reasonable amount of disk space – 20GB or more; a CD, DVD or CDRW; and a modem and networking capability. It is only individuals with demanding needs such as intensive gaming, or video or image manipulation that really need more. Individuals who store large libraries of picture or graphics files, music files, or video files will require substantially more disk space.
Before shopping, you need to get a clear idea of what your PC needs are and in what timeframe you are going to need a new PC. If your need for a PC is immediate, then you must try to find the best deal from a local electronics retailer. In addition, if you need or must have
During POST (Power On Self Test), the BIOS try to get information about all the devises Connected to the system. After checking the processor and RAM it checks for devise such you’re hard disk, CD-ROM, etc., and display them on screen with messages such As ‘detecting IDE drives…’ and Found Primary Master….’etc. Sometimes your BIOS Just refuses to recognize your hard disk, basically making it useless-there’s no way windows will recognize your hard disk if the BIOS doesn’t. Let’s see why this happens:
The most common reason is a loose or badly connected data cable. Make sure the data cable is plugged in properly, both into the hard disk, as well as the motherboard. The same goes for power cable, so check that as well. Also, make sure that the red lines on the data cable and power cable are adjacent to each other.
One you’ve ruled out any cable problems, check the jumper setting on the drives. If two drives are connected to a port, make sure one is set as master and the other as Slave, or else both are set to Cable Select.
Next, make sure your drive controllers on your motherboard
One fine day you start your PC and get messages that say,”Book Disk failure”. The problem is that the hard disk is detected but the OS does not load. The system may get stuck in the second screen during the booting process or the OS might display an error message and refuse to load. Such situations can be trouble some as they leave you with very few troubleshooting options
One of the common problems in dual boot systems is of the boot loader getting corrupted. For example, you have a system running Windows XP and Linux using Lila as boot loader. If Lila gets corrupted, you can not boot into either OS.When this happens, you have to boot into the system using some other media, such as a boot floppy or the Windows Dafter booting go to the command prompt, type ‘fdisk/mbr’ and press [Enter]. Note that if you use Windows 2000 or XP, boot into the recovery console and give the command ‘fixmbr’ to clear the MBR. Unfortunately, after you restart, it will boot to Windows directly, without any option of booting into Linux. You will have to restore LiLo again from your Linux CD, or
Today PC is considered as the one of the most essential components of our daily life. We can’t imagine a single minute without the presence of a PC. From office to our home, everywhere it has a strong presence.
But buying the right PC is not so easy as it sounds. One of the easier processes is buying a Branded PC. There are big names in this field. And they come with lucrative offers to stay ahead in the competitive market. But the buyer always has a dilemma. Which one is the best and cost effective? If one branded PC has one advantage, the other has one more advantage, so the best possible way is to build your own PC with all the advantages that you require. Knowledgeable persons, however, prefer buying an assembled PC, as it is cheaper in price and can be custom built.
Here are few tips for buying an assembled PC:
· Make a list of hardware that you require. This can be done by consulting with someone who has a solid knowledge.
· Find out a shop that has market goodwill.
· Ensure that all hardware parts have
Nobody likes a cluttered desktop
OK, maybe somebody somewhere in the world likes a cluttered desktop, but it is the goal of most office workers to keep their work area clean and clutter-free. Many studies suggest that such an environment is conducive to creativity, brainstorming and productivity. Whether or not this is true, it looks bad and low-tech.
Wirless is hot
With the introduction of new Wimax standards (the underlying technology driving wireless USB and wireless FireWire, among other emerging wireless technologies) just about everything except the power supply and monitor are commonly found in a wireless format.
Welcome Wireless VGA
The limitation on a wireless VGA (adaptable to DVI or HDMI) is no more – retailers are now offering wireless VGA adapters capable of transmitting a wireless signal to your monitor. The monitor still requires a power adapter, but you now have the flexibility of locating your computer in another room or section of the office. This is very useful when dealing with a media center or a computer powering multiple remote displays.
Most vendors do not have residential permits for these devices…yet
Right now, unfortunately, these are not approved
Overclocking, which was once the domain of power users and high-end gamers, has now gone mainstream. It’s true that overclocking might prove to be a shot in the arm for your CPU. However, if things go awry, you could well have a fried CPU.
There are scads of information regarding overclocking on the Internet. But sadly, most of the websites tout overclocking as a walk in the park, misleading users by concealing the associated risks. A computer novice, unaware of the risks involved, may set out to overclock the processor based on some advice he got from such a website. This really makes me cringe. Is the whole process of overclocking a no-brainer?
In simple words, overclocking your processor requires an alteration in the hardware settings in order to make it run faster than the manufacturer’s specification. The ideology is that the manufacturer’s ratings are a result of stringent trials and tests performed against the CPU. Then onwards, the CPU is tagged with a particular clock frequency at which it can take up substantial workload on a regular basis without malfunctioning. This clock rate is often a notch lower than the maximum a CPU can sustain.
Having a noisy computer can be irritating. Especially if you’re trying to listen to some smooth music or playing some games. This article is an attempt to reveal some basic techniques for reducing PC noise. Let’s get started …
Tip 1: Relocate the PC
The Moving the PC off the desk and onto the floor, especially if a few feet away from the main work area, will help reduce the perceived noise level.
Tip 2: Use Power Management
The hard disk drives are a major contributor the noise level in the system. Modern hard disks, when placed in a system with a BIOS that supports power management features (most do) can be instructed to spin down after a period of inactivity. This will reduce the noise level of the PC if you do a fair bit of activity without accessing the hard disk.
Tip 3: Don’t Add Redundant Fans
Some system cases have places where you can add additional fans to improve the air flow in the case. While this aids in cooling, too many fans contribute to the general racket of the PC. Don’t add more fans if this is a
