Computer Hardware Troubleshooting

downloadThere are different types of computer hardware, and of course, it would have been undoubtedly simple to deal with one hardware at a time and find out the problems associated with it. However, we know that when anything in our machine goes wrong, we are not completely aware of what exactly has happened, or rather, which part is causing the problem. So, I have decided that I will present to you the article in such a way that, we take up the problem first and then go for the troubleshooting, rather than taking a look at the hardware and the problem that it can cause.

Problem #1: Computer Does Not Start at All
If your computer does not get powered up at all, then the problem is very obvious. It has something to do with its power supply system.

Troubleshooting Procedure
This is one of the procedures that can either be very simple or can go way beyond your capability to solve. The solution may be as simple as replacing the power cable with a new one or as complicated as dealing with the SMPS of the machine. The SMPS is the Switched Mode Power

Choosing a Good Online Supplier for Your Computer Components

Choosing-a-Good-Online-Supplier-for-Your-Computer-ComponentsThanks to the internet, every item you could even want or need can now often be found online, in some cases being shipped from the other side of the globe to reach you. This is certainly true for computer components, which can be very beneficial as finding exactly what you need locally is not always possible.

Due to the need for high performing computer components for the building of new computer systems or their replacement of broken parts, there are many different types of online retailer supplying these items. They may be a specialist in one particular type of technical equipment, or they may instead be a general supplier that offers a wider range of related items.

Whichever retailer you settle on, it is important to verify a few things in order to ensure that you will be getting a product that meets your needs and expectations. Firstly, make sure that the online shop that you are buying from is reputable, as many computer parts can cost a great deal of money which could end up wasted.

To ensure reputability, it is advised to go with companies that

How to Choose a Good CPU Fan

CPU FANThe central processing unit (CPU) of your computer can generate large amounts of heat, which if not dissipated properly, can damage the internal components, rendering your computer useless. For the smooth functioning of your computer, you must ensure that you have a proper cooling system in place, that can effectively dissipate the heat generated and keep your system cool.

The cooling system for your processor consists of a heat sink and a fan. The fan is attached to the heat sink, which is a block with numerous fins. The heat generated by the CPU is dissipated by the fins of the heat sink, and the airflow created by the movement of the blades of the fan helps to speed up the process.

It helps to know that the heat sink and fan that come with a new CPU are mostly of average quality, and only do a fair job in cooling your system. If you want a computer that works silently, or if your computer has been overheating of late, then it’s highly recommended that you invest in a high-quality fan and heat sink combination. So, how do you choose the right one for

Difference Between Hardware and Software

The very basic difference probably even a child would tell between software and hardware is that, the latter can be touched and are actual physical components of a device.

However, the former (software) is simply bits and bytes, and is completely intangible. It can also be called the digital component of a device. Even though the basic difference between them is quite clear to most of us, there are some more aspects about each, one should consider when reading about differences between the two.

Let’s do a hardware vs. software analysis and see what they are.

Hardware and Software: What is the Difference Between them?

What is Hardware?
Hardware is a physical entity, or something which is tangible. However, hardware isn’t of any use without proper software, and vice versa. For instance, a microwave oven won’t recognize Android, as it is necessarily meant for a mobile phone. Likewise, an operating system or application software is of no use without suitable hardware. In brief, hardware of any device includes wires, circuit boards, chips, internal circuits, and every minor thing required for an electronic device to function.

Types of Network Hardware

computer network is not made up of one machine or even one type of machine. It is a carefully designed system of different hardware components (networking devices) working in tandem with various rules and communication protocols. From the network scenario in a household, to a medium scale network in a school or mall to a large, border-crossing network of a corporation or service, a computer network is made up of various hardware parts, some standard and some rare and more complex. So, what are the different types of network hardware? Read on for a listing of such devices and a brief explanation of each.

Types of Network Hardware

Cables & Wires
Everything may be turning wireless nowadays but at least 2-3 wired connections have to exist somewhere in a computer network. Connecting a desktop to a router or the router to the modem, such connections are always wired and the common cable type used is CAT5 RJ-45. Wiring is typically thought of as being a Layer 1 (physical layer) device as raw data or signals are transferred from one end to the other.

NIC
Network interface cards is easily one of the most important components of a computer network. It is a hardware

How to Upgrade Graphics Card

The graphics card is also known as video card, graphic controller, graphics accelerator or display card. It is a PCB (printed circuit board) that has three major components. These components are video memory, video BIOS, and graphics processing unit.

The graphics card should be changed if it gives a poor performance or if you want more speed options for the computer games. In the first case, you need to verify that it is the reason for the poor performance and not the computer. To do this, use the scan disk or defragmentation options and look for bad sectors on the hard disk. You can also try using other ways to speedup your computer. If they do not work, you can conclude that the lowered performance is due to the faulty working of the card. Once it has been established that the graphics card is responsible for the low speed, you should upgrade it.

Some video cards are integrated in the motherboard and some are externally connected to the computer. Older versions of motherboards used a PCI (peripheral computer Interconnect) slot in order to plug-in the video card. Newer versions of computers use the accelerated graphics port (AGP). The latest version of computers

Computer Hardware Repair and Maintenance

What is computer hardware? Hardware components like the monitor, keyboard, CPU (Central Processing Unit), mouse, and other I/O (Input-Output) devices constitute a computer. The working of the monitor, keyboard, mouse, and I/O devices depends largely upon the CPU. Due to some minor causes, like loose connections or dust saturation, any of them can stop functioning.

Faults occurring in the CPU are most hazardous, as it has a very complicated structure. The CPU is an assembly of the motherboard, hard disk drive (HDD), random access memory (RAM), compact disc-read only memory (CD-ROM) drive, and the floppy drive. Unless you are well-acquainted with the CPU hardware, it is extremely difficult to pinpoint exactly where the fault has occurred. If any one of these components fail to perform, there are a few repair tips that can be followed. In order to view the circuitry inside the CPU, its casing has to be removed.

Motherboard
The entire functioning of the computer depends on this component. The processor chipset, that performs all the logical operations of the PC, is embedded in the motherboard. Ribbon cables, power supply, CPU, and RAM are the things to be checked first on the motherboard. Check if any of the ribbon cables

Computer Hardware Basics

Basics for Beginners

It is essential to understand the fundamentals of hardware before moving on to any high level technical stuff. A typical computer system has 2 very basic components:
CPU (central processing unit)
monitor.
Of course, in order to actually be able to use the system, you input devices, like the keyboard or mouse. Other devices, such as joysticks, game pads, game controllers, etc., also fall into the category of input devices. The monitor is nothing but an output device (or a display device) whose purpose is to display all the information to the user. Monitors can be categorized as:
CRT (cathode ray tube) monitors
flat screen monitors.
CRT monitors are the box-like monitors that have been around since the last 10-15 years. Flat screen monitors are relatively new, and they too, are of 2 types namely, plasma monitors and LCD monitors. The CPU is the actual functioning unit, i.e., it is the component that is responsible for the actual computing that takes place. The CPU consists of the following components:
Hard drive
Motherboard
RAM chip
Processor
Video card
Graphics card
Sound card
Processor and cabinet fans
USB ports
LAN card
CD/DVD drive
Floppy disk drive
Cables
These components have

Sound Card Installation

If you know how to install sound card on your computer, you will be able to listen to all sorts of audio files. Music files, videos, movies, and audio-enhanced presentations are just some of the files that you can enjoy if you have it on your machine. Most computers that are available in the market today already have it on them, but sometimes you may need to install one.

Laptop computers do not provide you the option to open them up at will, and doing so nullifies the warranty. So, laptops will always have the best possible sound card installed in them when you buy them. On the other hand, desktop computers can be opened any time you wish. If you know how to install one, all you need to do is open up the machine and go ahead with it; it is as easy as it gets, and it only takes a few minutes.

Procedure

First of all, you need to be clear about why you are installing this card. If you are facing problems, try some other solutions before you set out to replace it. But, if your computer does not have one at all, then you surely need to install

How to Access Your Computer BIOS Setup

What happens when you turn on your PC? Lights come on the keyboard and monitor, the computer’s brand logo may appear on the screen, then the operating system loading message appears. This is all occurring on screen, but in the background, your computer is actually powering on and preparing its external and internal parts. Many assume the Operating System (OS) is the first program a computer loads and operates on but the actual start-up program is the BIOS.

BIOS stands for Basic Input/Output System, which is inbuilt in every PC during manufacturing and is loaded, run and executed when you press the power ON button of your PC. The BIOS is a sort of firmware interface for a computer. Different components, such as pen drives, graphics card, keyboard and mouse and disc drives attached to a computer, need to be initialized and identified to the computer. The BIOS does this in the form of a check-list (“turn USB ports on”, done) and this procedure is known as POST (power-on self-test). The operating system itself is a program, which needs to be loaded and executed. This too is performed by the BIOS, which locates the OS program on the computer’s hard disk

Tips for Buying a Webcam

When it comes to electronics shopping, one cannot depend on instincts, price or trends. Today’s trend can end up being tomorrow’ bust. Plus callbacks and product returns can happen to any gadget. Pricing is often misleading. You can end up paying a lot more than necessary for something which could be replaced tomorrow. With electrical devices, one needs to be well-versed in specs. Specs or specifications can help you understand whether that device is right for you in the first place.

A camera with a low resolution is of no use to a nature photographer, who needs detailed images. Similarly a high-end camera with enhanced zoom, is not the device for your average soccer mom. One such ambiguous device is the webcam. Capturing video and transmitting it online for someone somewhere else to view is the webcameras basic function. But when buying a webcam, there are certain specs and points to keep in mind. Read on to learn how to pick the best webcam for your PC.

5 Tips for Buying a Webcam

1. Buy Based on Hardware
Based on what they are going to be connected to, webcams can be differently designed. Most laptops nowadays have a built-in webcam but older laptops
