Computer Hardware Repair

What is PC equipment? Equipment segments like the screen, console, CPU (Central Processing Unit), mouse, and other I/O (Input-Output) gadgets constitute a PC. The working of the screen, console, mouse, and I/O gadgets depends generally upon the CPU. Because of some minor causes, as free associations or tidy immersion, any of them can quit working.

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.

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 or the power supply cord is loose. Check if the RAM chip has been misplaced from its slot. The CPU (chipset embedded in the board) will not show any marks on the outside if it is blown. The only way to check whether the CPU is working or not, is to test it by mounting it on the motherboard of another PC. The motherboard has a real-time clock, ROM BIOS, CMOS RAM, RAM sockets, CPU sockets or slots, cache RAM slots, keyboard controller, interrupts, internal connectors, and external connectors mounted on it. Do not tamper with these components, unless you know each and every one of it well. Do not touch the motherboard without turning off the power.

Hard Disk Drive (HDD)
Also known as hard drive, it is the long-term storage device of the system. If the hard drive cannot be detected, check the jumper setting. The jumper setting can change the mode of the hard disk from master to slave or vice-versa. Make sure the Windows version being used for partitioning is consistent. Check that each drive has been assigned a drive-type. Make sure the pin numbers of the plug are attached to the corresponding pin numbers of the socket. Do not force the plug into the socket with extra force, the pins may bend. If the plug is not fitting perfectly in the socket, try inserting it again by flipping it over. Do not attempt to open the hard drive without enough knowledge of its components.

Random Access Memory (RAM)
It is the temporary memory of the PC. The data in the RAM is erased when the computer is shut down. Check if the RAM is misplaced from its slot. While replacing the RAM in its slot, check the small niche at the center of the chip (the niche indicates how the RAM is supposed to be placed in the slot and may not be at the exact mid position of the chip-strip). Do not forget to secure the side clips that hold the chip in place. If you are unable to secure them, it means that the chip is not placed correctly in the slot.

Compact Disc-Read Only Memory (CD-ROM) Drive
Data stored on external storage device like compact discs (CD) is read by inserting the CD in the CD drive. If the CD drive is not functioning, check if the CD is scratched. If the CD works fine in another PC, check if the power cable of the former drive is loose. Check if the plug and socket pin numbers match. If the tray of the drive is not opening, right click on CD-ROM icon and select eject option. If the tray does not open, insert a straight thin metal pin into the edge and try to pull it open. Do not apply too much of force while doing so. Avoid connecting the CD-ROM drive on the same controller cable as the primary hard drive, this will slow down its performance.

Floppy Drive
If the floppy disk is not opening, try opening it in the floppy drive of another PC. If the disk does not open, then it is probably corrupt. If the disk is stuck in the drive, hold down the eject button for sometime or right click on floppy drive icon and select eject option. If the disk is still stuck, wiggle it up and down till it can be ejected or use tweezers to pull it out. Do not apply too much of force while doing so.

In order to avoid any kind of faults, following maintenance tips can be followed:

  • Do not let dust saturate on the motherboard. Clean it with a vacuum cleaner or a hand broom once in 2 to 3 months.
  • The hard drive mostly does not need any external cleaning, though by performing de-fragmentation and disk clean, it can be prevented from crashing.
  • In the case of the CD-ROM, do not pull the tray forcibly. Make use of the insert/eject button rather than pulling and pushing the tray.
  • Clean the tray once in a while. Do not keep any heavy object on the tray. Avoid running scratched or damaged CDs in the CD-ROM.
  • If the CPU fan is making too much noise, unmount it and oil the bearings.
  • Do not attempt to start the PC if the fan is not in a working condition.
  • If the fault persists, contact professional services. Also make a note of what exactly is happening when you start the PC. It makes the diagnosis a lot easier for the professional.

The CPU is the brain of the computer. Proper maintenance of the CPU, as well as all other components, enhances the computer performance.

Computer Hardware Troubleshooting Tips

It’s surely disappointing to experience some equipment issues when are you amidst some critical work on the PC. The article beneath gives you some convenient PC equipment investigating tips and devices.

  • You may also restart your computer and then check whether the monitor is working or not.
  • If none of these tips work out, you may have to consult a professional technician.


  • The keyboard is an important part of the computer, without which you cannot perform several tasks. It should be kept away from dust and dirt to ensure proper functioning.
  • If it doesn’t work, you first need to check its connection with the CPU. If the connection is fine and it still does not work, simply try to connect it to another PS/2 socket or USB port (in case of a USB keyboard).
  • In case of wireless keyboards, special drivers are needed to be installed in the computer for proper functioning. Ensure that such drivers are installed.
  • Also, make a point to check whether the drivers are updated. Hold the keyboard in an inverted manner and remove the dust or debris, which is hampering the proper working of a key or a set of keys. You can also remove dust with the help of a vacuum cleaner or an air compressor.


  • If the cursor on the screen is not moving in a smooth manner, you need to check for dust or any residue on the trackball rollers, which enable the computer to accurately identify the movement of the mouse.
  • Remove the rear mouse cover, which will let the ball come out, clean the trackball if needed, remove the dust or residue, put the ball in again, and finally put the cover back. Check whether this works.
  • If the cursor doesn’t move at all, check whether the mouse is correctly connected to the CPU.
  • If it’s a USB mouse, try to use a different USB port.
  • There could also be the potential threat of a virus if the mouse pointer doesn’t work in an acceptable manner. If so, run an updated anti-virus software and delete the virus as soon as possible.
  • Check if the mouse drivers are corrupted, if yes, reinstall them.


  • If the printer doesn’t work, there is a possibility of a paper jam, which normally occurs if the papers are not placed in the tray in a right manner.
  • In case of bigger printers, you may need to open various printer parts to get to the place where there is a paper jam. This exclusively has to be done by a professional printer technician.
  • Don’t use tools to remove the paper jam, as some components may get damaged during the process.
  • If the printer doesn’t turn on, the power cord may be loose, and needs to be plugged in properly. The cord which connects the printer to the computer also needs to be checked.

These are some of the very common computer hardware troubleshooting steps, which can be followed before taking the PC to a professional hardware repair shop.

Tips to Computer Software and Hardware Installation

In today’s day and age, PCs have turned into an a vital part of our lives. We can discover them wherever around us. They have an assortment of huge and imperative applications in a few distinct fields, including enterprises, horticulture, inquire about, drug, and so forth.

For most of us however, the term computer signifies the PCs that we use at our homes and offices. We use them to watch movies, listen to songs, play games, make work-related documents, etc. It is really impossible to carry on our daily lives, both at our homes and our workplaces, without computers.

Since we use computers so extensively, it is necessary that we have some understanding about at least the installation of its basic components, namely the hardware and software. This knowledge can prove to be vital, especially when we wish to upgrade our PCs.

In the very basic sense, computer software constitutes the programs that run in it, while hardware constitutes the monitor, keyboard, and all the other peripheral devices that are connected to it. Both these components are essential for the working of any computer system.

In the following sections, we give you an overview of the generic procedure for the installation of both, the software and the hardware in your computer.

Computer Software Installation

The operating system of your computer is an important factor to be considered when you install any software. It is the base program, which is designed to manage the hardware and software resources in your computer.

Before you install a software, the first important step is to check the configuration of your computer, and the system requirements of the software. The configuration of your computer must match the requirements of the software to be installed.

Sometimes, the software to be installed is compressed in a .RAR or .ZIP file. In these cases, before installation, you have to uncompress these files and folders. For doing this it is essential that you have a decompression software application installed on your computer.

Every computer software comes with a ‘Read me’ file. This ‘Read me’ file contains all the instructions that are required for running the installation procedure. Sometimes, when you install a software, it may ask you to install another program that is required for the proper execution of the software. The computer may even prompt you to install the supporting software after you complete the installation.

Before you install any software program, it is advisable to close all other programs and utilities. Some Antivirus software applications may require you to turn off the firewall and disable the Antivirus in order to install it. Especially when installing software applications related to computer networking or web browsing, it is recommended that you disable the Antivirus and the firewall before proceeding. Finally, to complete the installation, you may require to restart your system.

Computer Hardware Installation

With advancing technology, the computer peripherals are frequently upgraded, and many newer and better ones are made available each day. To install one or more of them to your existing system, you need to first unplug all the power cords of your computer that are connected to the mains, before moving on to connecting the hardware.

The hardware package may include an accompanying CD that contains the software which will help your computer’s OS in recognizing the new hardware. Install this software before you connect the hardware to the computer, which must be restarted after a CD installation is complete. There are two different types of computer hardware. They are as follows:

External Hardware
The external hardware involves all the peripherals that are connected to the desktop computer externally, via various ports. These are the USB, serial and parallel port, Firewire, Bluetooth, PS/2 and PC card. The external hardware installation can be done by a lay user, even without much knowledge of computers. They can be connected to the computer directly once it is switched off.

Internal Hardware
The internal hardware is a bit complicated and requires some basic knowledge about the computer internals. The CPU cabinet has to be opened by removing the side panels. Then you are required to identify the slot in which you have to plug your hardware. After that, you have to plug in the hardware that is to be installed and ensure that it has fit properly into its slot.

Once the hardware is installed, the side panel and the screws need to be replaced into their original places, and all the wires have to be connected to their respective slots. The power cord can then be plugged back into the mains and the computer can be switched on.

Most computer software and hardware installation can easily be carried out with the help of some basic knowledge of computers. If an installation procedure seems too complicated, you should ask a professional to install or help you with it.

Hardware components of a computer system

Because of headways in Information Technology (IT), there have been different advances that are being utilized everywhere throughout the world. What’s more, with regards to innovation, a mix of equipment and programming is clear. There are a wide range of sorts of PC equipment and programming that we use in our everyday lives, be it at an individual or expert level. Step by step, fresher innovation is being put to utilize. On that note, this article underneath gives a rundown of the equipment parts of a PC framework.

The types of devices mentioned below are individual components, which play a very important role in making the operation of the system possible. This is just a brief explanation of all parts.


This is the most important type part. It is a circuit board, wherein various parts of the system are set up. All input devices work when they are connected to the motherboard. RAM, CPU, and other crucial peripherals are installed on the motherboard. You can say that this is what runs the whole system.

Random Access Memory (RAM)

The RAM is a small chip that fits on the motherboard. It does the job of storing data on a temporary basis. RAM chips are generally available from 256 MB to 6 GB or more and are upgradeable. The more the RAM, faster the functionality.

Central Processing Unit (CPU)

The CPU is a small chip installed on the motherboard that does the job of running computer programs. It is more commonly referred to as the processor. The speed of computer functioning also depends a lot on the processor’s capacity. Without the CPU, you will not be able to play games, browse the web, or run any other applications.

Hard Drive

The hard drive is where all the program files are stored for retrieval or further operation. There are many storage capacities of hard drives which normally range from 80 GB to 1 TB or more. External hard drives are also available nowadays with a storage capacity of around 8 TB.

Power Supply Unit

As the name suggests, this device is responsible for providing the system with power to function. It is an electrical box fitted inside at the back of the cabinet, which connects to and powers the motherboard, disk drives, and other similar devices. It also has a fan for cooling purpose in case of overheating.

Keyboard and Mouse

The keyboard contains a series of keys that contain all the alphabets, numbers, and special characters. It is used to type text and numerals on the console. In desktop computers, it is a separate device. In laptops, it is inbuilt. It is a very important device, as it used for typing, software controlling, and gaming. The mouse is a device that is used for moving a pointer on the console. It contains two or three buttons for conveniently accessing any file, folder, or software.

Pen Drives

The floppy drive used to be an important device that would accept the floppy for data processing. Today, no one uses them. Instead, there are pen drives that are small but extremely useful peripherals. These are the ones, which have substantially reduced the use of data CDs to transfer files and media. DVD drives are parts, which can be used for viewing data from DVDs.


The monitor is another important part. It is an electronic display that helps us to view the various software and their functionalities on screen. It comes in the conventional CRT (Cathode Ray Tube), LCD (Liquid Crystal Display), and Plasma types. The CRT was invented way long ago. Nowadays, the LCD and Plasma are more in demand because of their efficiency and clarity.

Printer and Scanner

The printer and scanner are both mostly used in offices. Nowadays, both these two devices come in a single device for better space and energy consumption. The printer is used to take print-outs of essential documents and images, while the scanner is used to scan documents and view them on screen with the help of image software. In other words, a printer is used to convert soft copies to hard copies, while a scanner is used to convert hard copies to soft copies.

These are just a few of the different types of hardware devices used in information technology. There are many others, such as audio and video graphic cards, router, modem, PCI cards, cabinet, etc. The types and specifications of these devices cannot be certain, as many useful advanced technologies are being introduced in them lately.

Tips to Upgrade Graphics Card

The design card is an absolute necessity for PC amusements. As fast progression is found in PC and related advances, overhauling PC equipment is crucial to increase greatest advantage from the most recent innovation.

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 use the PCIexpress, which has a speed twice of the AGP slots.

The task of upgrading the graphics card in your desktop computer, involves finding out the type of slot in your computer motherboard. If your computer system is relatively quite old, then it is likely that it has a PCI slot. In this case, you have to upgrade related hardware in your computer system, as well. This is because, nowadays, graphic cards compatible only with PCIexpress are available. Additionally, they also render high-speed outputs.

The power supply required for a graphics card should also be considered before buying one. The power supply or wattage of the computer must be checked. The power supply ratings range from 350-500W. Also, the available computer RAM must be taken into consideration. Minimum RAM of 512 MB is required. Once all these steps are done, you can buy a new video card. Make sure that you compare all the options available in the market, and choose the one that best suits your needs.

To remove the older one and upgrade the computer hardware to a new video card, follow the steps given below:

  • If you already have a graphics card, un-install the drivers of the same. Download the drivers of the new one that you’ve purchased and store them on your computer system.
  • Remove the overclocks, usually set to increase the performance of your computer by increasing the clock rate. Set the computer system to its original specifications and turn it off.
  • The power cord should be unplugged. Open the cabinet and search for your PCIexpress slot. The PCIexpress slot has a locking clip, which is used to mount the card. Remove the older card and mount the newer one. Store the older card in an anti-static bag, as you can use it as a back-up.
  • The computer system can then be switched on, after carefully placing the graphics card in its slot. Start your computer and install the drivers which were downloaded earlier. This ends the up-gradation process and you can start playing games.

The graphics card is basically used to ensure performance, drive a digital screen, and support dual screens for playing games.

Computer Hardware Troubleshooting

Here, in this article, we will manage the essential PC equipment investigating steps. We won’t manage the issues in the diverse equipment gadgets, but instead take up an issue, its reasonable justification, analysis, trailed by the investigating part.

There 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 Supply, the box at the upper left hand corner of your CPU, which powers up each and every component in your computer. If the problem lies with the SMPS, then solving it is not one of the DIY tasks that you would like to take up at home. It will need good technical expertise to solve the problem. Many times, the problem may have just one solution, that is, replacing the SMPS.

Problem #2: Computer Freezes or Shuts Down Suddenly
If you are facing the problem that your operating system stops responding suddenly or the computer shuts down by itself, then there may be some hardware related issue out here. Before I start off with the troubleshooting tips for this problem, I should tell you that most of the time, these are problems related to some software running in your system or because of some wrong driver installation. However, assuming that you have already checked out these problems and are sure that the problem is not related to the software, let’s start off with the hardware troubleshooting part.

Troubleshooting Procedure
Most of the time, this is a problem related to heat issues. If your processor gets heated up then there is a chance that your machine may shut down. The probable cause for this problem is that the fan in your CPU is not working properly. Here, I am assuming that you are using a desktop, as troubleshooting a laptop, would, of course require a lot of expertise. You can make out whether the fan is rotating properly, by simply observing it at the back of your CPU. There are also certain on screen system programs which can show whether your processor is over heated or not. If your fan is not rotating smoothly, then you have to get the connections to your fan checked. Another step that you can take is that you need to observe if the BIOS can properly load the fan when starting off the computer. However, if you find out that your fan is working properly, then you should take into consideration any new hardware that you had added to the system. Try removing that and check out if the machine restores back to working properly. There are chances that this hardware may be faulty. Replace it with a new one. Again, if you have not added any new hardware to your system in recent times, then the reason may be some part that is already there in your machine. Open your CPU cabinet and remove any extra RAM or extra hard disk that you are using. Check out if your computer works properly without that particular component. You can also try disconnecting your MODEM to check if the machine works properly.

Problem #3: Computer Boots Up Only from Floppy Drive
After starting up your system, if it demands you to insert a floppy disk to install the system, then probably there is some problem with the hard drive of the system.

Troubleshooting Procedure
Before going into the troubleshooting part and considering the hard disk to be corrupt, figure out in the BIOS settings, if your hard disk has been given the first priority for booting up. If it has not been given the first priority, then change the priority level and put your hard disk at the first priority level. If this does not help, then probably your hard disk is corrupt. In that case, if you have a recovery or backup system in your computer, then use it for recovering the data and the operating system. The other possible solution is that you need to reformat your hard disk.

Introducing a decent antivirus programming is key to shield your PC and information from outside security dangers. Notwithstanding, with the scope of projects accessible in the market, picking one can be an extreme. Here is a short guide that will make it simple for you.

A computer without a good antivirus software is akin to the human body with its immune system turned off. Such a system is extremely vulnerable and can be easily compromised, especially when the computer is connected to the Internet. Ergo, installing an antivirus program is no longer a choice, it’s a necessity.

About Antivirus Software Programs

A computer virus is a malicious piece of software code, written with the intention of stealing data, gaining unauthorized access, or compromising your computer’s security. There are many virus weapons in the hacker’s arsenal, which can only be combated with the best antivirus program installed on your computer. Such a software is designed to detect the presence of malicious computer programs or viruses like trojans and worms on your system.

Most of them work by scanning your system files and look for virus signatures, by referring to a database, which is regularly updated. What complicates matters is an Internet connection, which is a hotbed of viruses, waiting to pounce upon your system. The best programs offer protection for all the exposure points of your system.

This includes network security, Internet security, protection for email and Internet browsing, P2P protection, and a firewall, besides real-time scanning for the system. Let us see what features to look out for, when buying the software.

Selecting One

When checking out reviews, you will discover many programs that offer basic features, while there are paid versions of the same programs, which offer a wider range of protection features. Most of them are ‘suites’ which offer a wide range of security features.

Rather than going for a free standalone program, it is highly recommended that you go for a paid program which offers all-round security. Here are the prime features that I would check for, when buying an antivirus software.

Check For Virus Detection Rate
The most important thing you want to know is, how good the program is at detecting computer viruses. One way of determining the detection rate is to use the free version. Another, is to rely on expert opinion, in the form of reviews of these software programs provided online. Consider the results of benchmark tests.

Go for antivirus engines which offer a solid track record, in terms of virus detection. Opt for a program that uses the system resources, without slowing it down too much. Make sure that it has a rootkit virus detection tool and a registry cleaner.

Look For Internet Security
Among all the scanning features provided by a program, look for Internet security features, that include link scanning, email scanning, P2P scanning, and network security. Real-time scanning and scheduled scanning is offered by almost all programs these days. If you use your computer terminal for online banking transactions, it is essential that your antivirus program has anti-phishing filters.

Check for Malware and Spyware Protection
Malware and spyware are two breeds of viruses that need to be effectively contained and removed to ensure smooth operation of your computer. See to it that the software you opt for, has a good malware and spyware detection rate.

Check the Firewall
The OS firewall is not sufficient to block incoming security threats. So, one feature that you should look out for in an antivirus, is the provision of a firewall. It can effectively block out unauthorized connections.

Depending on your level of usage and range of computing activities, you need an antivirus program that can provide you with all-round protection. Symantec, TrendMicro, Kaspersky, McAfee, Avast, Avira, Norton, AVG, and ESET NOD32 are some of the best antivirus brands to choose from, in my experience. Select one which suits your overall requirements and budget.

If you don’t want to spend on buying an antivirus program, the Avast Antivirus free edition is a highly recommended choice. Go for programs which offer a wide range of security features, which includes a strong firewall, Internet security, real time scanning, and a regularly updated and robust antivirus engine. Check out reviews and read the comparative benchmark test results, presented by reviewers, and choose one which suits your requirements.
