Improving The Performance of Your Computer March 21, 2025

Computer
performance is important to every PC owner and user. There are several
ways that you can boost the performance of your computer, without having
to pay for expert advice or technical help.

Once
you bring your personal computer home from the store or receive it in
the mail there is no one around to offer basic personal computer
maintenance tips for cleaning up and improving performance of your
computer. Maintenance and cleaning up of your PC should be part of a
regular routine to ensure that you don’t have any long-term problems
with the computer.

If still your PC is running at a snail’s pace,
then perhaps you have a low computer memory. Perhaps the software you
constantly use take up a lot of memory just for them to be installed and
to run. Even if you are not currently using the software, they can be
running in the background, causing your system to slow down. If this is
what you have detected, then uninstall some of the software that you
rarely use to maintain your PC.

One other tip that you should
definitely consider is to always use the scandisk and disk defragment
tools that are available freely on all computers. These programs monitor
the health of your disks and help to reorganize the data in a manner
whereby the computer can easily access, without taking the time to sift
through cluttered databanks. A fragmented disk that clutters up over
time is inevitable, and the tools here will help eliminate the problem.

The
windows operating system stores crucial information about your computer
in a database file. In this database it stores information about your
hardware, software and settings you made to this software and hardware.
This data is crucial to keep your pc running smoothly. All the changes
which are made to the pc are stored as keys in the registry.

If
your computer slows down quite a lot, you most likely need a registry
cleaner program to check your computer’s registry database. This
internal PC database is vital for a computer that performs at top speed.
Poorly-written software programs can leave traces behind and introduce
errors into your registry. Be sure you get a highly-rated registry
cleaner that has a good guarantee.

ncreasing the memory on your
computer is highly recommended and in today’s market comes at a very low
cost. It will then dramatically increase your RAM (random access
memory). Using certain software can alert you to the other servers that
are running low on RAM. You can also check your performance via the task
manager in your computer settings.

Also, it is important to run a
good anti-virus program to keep your system from becoming infected by
viruses and worms, both of which can cripple not only your computer, but
your entire network. With a bit of searching, you can find some great
free anti-virus programs that are available for download. There are also
a good number of excellent commercial programs available for purchase.

These
simple steps will help you improve the performance of your computer
without necessitating any additional costs, unless you need more memory.

Important Computer Hardware Components And Parts March 11, 2025

Computer
hardware consists of the different components of a computer including
the CPU or the Central Processing Unit, mouse, keyboard, monitor, hard
disk, RAM or memory, drives such as the DVD, CD, optical, tape and so
forth. All these components are essential for the proper functioning of a
personal computer.

Understanding Computer Hardware in Detail

The
whole computer is available with the above mentioned components but it
is also possible to purchase these components individually from many of
the online and offline stores. Some of the most important components
include the following:

Central Processing Unit or the CPU:
the CPU refers to the processor of the computer. Although there are a
wide number of companies that manufacture CPUs or processors for
personal computers, the Pentium chip manufactured by Intel is widely and
commonly used by most of the manufacturers.

Keyboard:
most important computer hardware includes the keyboard which is
essential to enter commands and words. Every key in the keyboard is a
representation of an alphabet, number, sign, function and so forth.
There are keys which represent actions like Delete, Enter, Alt, Ctrl,
Page Up, Page Down, Home, End and many more. Each different key has a
specific function.

There are 101 keys in an ordinary
standard keyboard. Keyboards which are ergonomically designed have
special features to make typing easier. Each key has two characters
which can be typed by pressing the Shift key. The Ctrl, Alt and Shift
keys are known as the command keys.

Mouse:
Important computer hardware also includes the mouse. It is used for
navigating on the computer’s screen, to click on options, to select
objects and to access information. There are usually two buttons on the
mouse- one on the left which is used for selection and one on the right
which is used to access information. There are different types of mouse
available today which include optical mouse, scroll mouse, laser mouse,
ball mouse and so forth. The scroll mouse, or the wheel mouse, has a
plastic wheel in between the left and right buttons on the mouse. This
important computer hardware also includes the optical mouse which sends
optical signals to the computer. The ball mouse includes a ball in the
mouse casing which moves when the mouse is moved on the pad. This
movement sends the required signal to the computer.

Hard disk:
computer hardware also includes hard disk which is a device used for
permanent storage of data. The performance of a computer depends on the
rotation speed of the hard disk. The higher the rotation speed, the
higher the performance of the computer.

RAM or the Random Access Memory:
RAM is also a computer hardware that stores information temporarily.
But however, while rebooting or turning off the computer, this
information will be erased. The performance of the computer depends
largely on the RAM and if the size of the RAM is larger, the computer
will perform better and faster.

Computer hardware
also includes components like sound cards, digital cameras, scanners and
modems. Different types of components are available and it may differ
according to the type of the computer.

Basic Parts of Cpmputer Hardware December 12, 2024

If
you are using a desktop computer, you may already know that there isn’t
any single part known as a “computer”. A computer is a system of
several parts working together. The physical parts which you could see
and touch are jointly known as hardware. There are some computer
hardware parts which collectively form a computer.

Computer Hardware Parts:
System Unit

The system unit is the heart of a computer system. Generally, it’s a
rectangular box placed on or beneath your desk. There are several
electronic components which process information inside this box. The
most vital of these components is the central processing unit (CPU), or
microprocessor, which acts as the brain of your computer. Another
component is the RAM or the random access memory which temporarily
stores data that the CPU uses while the computer is on. When the
computer is turned off, the information stored in RAM gets erased.

Hard Disk Drive

Your computer’s hard disk drive stores data on a hard disk, a firm
plate or stack of plates with a magnetic surface. The hard disks
normally serve as your computer’s primary means of storage, holding
almost all of your programs and files as it can hold enormous amounts of
information. The hard disk is usually located inside the system unit.

DVD and CD Drives

Almost all computers today come equipped with a DVD or CD drive,
generally located on the front of the system unit. CD drives use lasers
to read or retrieve data from a CD and several CD drives could also
write or record data onto CDs. DVD drives could do everything that CD
drives can plus they can also read DVDs. If you have a DVD drive, you
could watch movies on your computer. Several DVD drives could record
data onto blank DVDs.

Floppy Disk Drive
Floppy disk drives
store information on floppy disks, also known as floppies or diskettes.
Floppy disks compared to CDs and DVDs can store only a small amount of
data. They also recover information more slowly and are more prone to
damage. For these reasons, floppy disk drives are less admired than they
used to be, though some computers still include them.

Diagnosing And Troubleshooting Computer Hardware December 9, 2024

What is Hardware?

Are these terms familiar to you?
Monitor, RAM, CD drive, CPU, graphic cards are all hardware, or more
accurately, computer hardware. These components make up a computer,
working together with computer software to make a computer work.

Simply put, hardware is the tangible parts of your computer, parts you can touch, feel and so on.

Hardware Failures

As
mentioned before, hardware and software work together to form a fully
functional system, theoretically. However, rarely do you get a fully
functional system all the time. There will almost certainly be
malfunction of hardware, be it within the electronic circuits or even
the whole component itself. Sometimes, the originating factor of the
hardware failure is not the components of the system itself, but due to
outside factors such as environmental disasters like fire, earthquakes
and lightning storm.

Recovery of failed hardware components is not
a big problem by itself. It is basically identifying and replacing the
problematic component. However, hardware failures are most deadly, when
it affects daily routine and affecting critical personal or business
data. This is especially true of the most important component of a
computer system when it comes to storage of data, the hard disk.

The following is a list of common hardware failures:

  • RAM Failures

  • Power Connector

  • Hard Disk

  • Overheating

  • LCD Failures

  • Motherboard

  • USB Box

RAM Failures

Bad RAM is somehow harder to
diagnose as similar symptoms may be caused by software problems, other
hardware problems or even motherboard failure. However if you experience
any of these symptoms, users should check for bad RAM before attempting
any other troubleshooting.

Symptoms:

  • Windows doesn’t start showing different error messages each time.

  • Windows crashes (blue screen) or freezes frequently.

  • Windows crashes as soon as you try to start a program.

  • Unexplained random crashes and freezes without error messages.

Power Adaptor

The common weak spot on any
laptop is the DC power jack. If someone trips over the power adapter
cable while it is still connected to the laptop, there is a high
possibility that the power jack will get severely damaged.

On most
laptops, the DC power jack is soldered directly to the motherboard and
there are only three or four small pins holding it in place, which makes
the power jack rather weak. Any sideways pulling of the DC power cord
while attached to the laptop will usually dislodge at least one of these
pins, breaking the solder around it. Modern laptops use quite a lot of
power, from about 70W to 120W or even more. The bad electrical
connection from the dislodged pin will cause sparks and heating that
will eventually burn a hole through the motherboard and can even be a
fire hazard.

Symptoms which indicates poor contact between the DC power jack and the motherboard:

  • The battery is not charging properly or stays at half charge despite having to use the power adaptor.

  • The screen flickers (the brightness is changing) while the power
    cord is plugged in. This is caused by the laptop switching between DC
    power (screen is brighter) and battery power (screen is dimmer).

  • The DC plug gets hot after a few minutes of use and may even smell of burning.

  • There are “scratching” sounds coming from the DC jack.

How to test for broken power jack:


    1. Remove the battery

    2. Plug in the power cord

    3. Start the laptop

    4. Gently wiggle the DC power plug on the back of the laptop

If the laptop shuts down abruptly (looses power), find
the dealer to re-solder or change the DC power jack as soon as possible
as the motherboard has already started to burn around the dislodged
pins. The manufacturer might offer to replace the whole motherboard;
however the price of a new motherboard together with the labor charge
for installing it will usually cost more than the current value of that
laptop and sometimes can the pricing can cost over a thousand dollars.

Replacing
or re-soldering the DC power jack is not an easy job. It usually takes a
few hours depending on the damage and the model of the laptop. To reach
the power jack, the laptop has to be completely disassembled and have
the motherboard taken out. Then if the board around the dislodged pin is
badly burned, the power jack has to be un-soldered and the board has to
be patched.

After that a different power jack has to be
installed, attached to the case of the laptop and connected with wires
to the motherboard, as the patched board wouldn’t be strong enough to
support the original type of power jack that was soldered directly to
the board.

Hard Disk

Hard disk failures are
the most common computer hardware problems. And laptop hard disks fail
more often than desktop hard disks due to the portability of a laptop as
compared to the rather stagnant laptop. If user knock hard or drop the
laptop even a few inches while the hard disk is being accessed or
powered up, damage can be done to the hard disk.

Symptoms:

  • The laptop starts as usual but when Windows starts to load it goes
    to blue screen with either “UNMOUNTABLE_BOOT_VOLUME”, “hal.dll is
    missing or corrupt” or “WINDOWSSYSTEM32CONFIGSYSTEM” (or similar) is
    missing or corrupt. All these error messages indicate a file system
    problem. Sometimes it can be fixed by just scanning the hard disk for
    errors. However more than half of these cases indicate that the hard
    disk is starting to go bad and is probably developing bad sectors.

  • The laptop starts as usual but Windows freezes on the initial
    “Windows XP” screen, although the blue bar continues to move, and users
    are able to hear feint but continuous clicking. Hard disks have to be
    replaced.

  • As soon as the laptop is started there are loud clicks or grinding
    sounds and Windows doesn’t load. Hard disks have to be replaced as well.

  • Shortly after starting the laptop a message appears (usually on a
    black screen) “SMART test failed. Backup your data immediately and
    replace the hard disk” or similar. Well, that says it all. S.M.A.R.T. is
    a self-test that is build into the hard disk.

In almost all cases the laptop can be started from a
“live” bootable CD and everything works normal. In rare cases the hard
disk PCB (printed circuit board) may get short circuited and even burn.
In this scenario, the laptop won’t start unless the hard disk is
removed.

A good tool to use to check for hard disk lifespan is ADRC’s hard disk checker. It will scan the hard disk for bad sectors and inform you if the drive is still of good usability.

Overheating

Overheating
happens when inadequate airflow from outside the computer’s case across
the CPU and motherboard and back out of the case usually via the power
supply fan and other case fans.

Once the airflow is disrupted,
heat builds up rapidly within the case. This causes components to either
shutdown, if such protection is built in or performs erratically. Over
the long term, overheating can irreversible damage components.

It is also advisable to keep the computer in a dry and shaded room, which is clean and little dust.

LCD Failures

The most common LCD or “Liquid Crystal Display” screen failure is the inverter, cable and backlight.

Symptoms:

  • The laptop appears to start as usual but the screen is black, if users move it, it turns on and works properly. Failed cable.

  • The laptop appears to start as usual but the screen is very dark,
    although it changes colour a little and users can see a very feint
    image. Failed inverter or cable 90%/10%.

  • Immediately after starting the screen has dark pink/red tint and turns dark after a few seconds. Failed backlight.

  • The screen flickers a few times but then turns dark, if users move
    it or tap it lightly on the sides, it flickers again. Failed cable or
    LCD 50%/50%.

  • Screen is either black or white (no picture) and external monitor works. Failed cable or LCD 30%/70%.

  • There are stripes on the screen (either vertical or horizontal) that
    change when users move the screen or tap it lightly on the sides.
    Failed cable or LCD 10%/90%.

Motherboard

Most motherboard related
failures are due to the “On-board” regulated supplies and component
failure within those circuits. The on-board power supply circuit had
partially failed and was overloading subsequent components else the
problem would be with the capacitors which are defective in the first
place.

A motherboard failure on a laptop that is out of warranty
would usually mean that it’s time for a new laptop. The price of a new
motherboard is usually higher than the current value of the laptop.

Symptoms:

Plug in the power adaptor and try to start the laptop.

  • Nothing happens.

  • The “ON” light comes on, the fan spins, but nothing on the screen (black) and you can’t hear the HD working after 10-15 sec.

  • The “ON” light comes on, the fan spins, but after a few seconds the light goes off.

  • After pressing the “ON” button the screen stays black and you can hear a quiet high-pitched sound coming from the laptop.

Corrupted or improper device drivers and operating system

Invalid
or corrupt device drivers can wreck havoc on a server, rendering the
system unbootable in some cases. Device drivers may also conflict with
certain application programs and cause problems with the computer
system.

As Windows Vista has just made its launch, chances are
some hardware is not supported or not supported fully by the new
operating system.

Also, system updates, driver updates can also fix your “hardware” problems.

See updating and fixes

Also,
it helps (occasionally) to call the respective support service for help
on the driver that is with that particular hardware.

Controller Failure:

A
controller failure can act much like a drive failure. However, when a
drive fails, users cannot access that particular drive; when a
controller fails, users cannot get access to all the drives, devices and
any other components that is attached to that particular controller.

A
controller fails because a component or components on the on the
controller board fails. When users trying to boot the system, they
cannot switch on, view, access, or even get hardware conflict messages.

Controller failure occurs due to one of the following reasons:

  • Devices/components not connected properly
      Verify that the cables are properly connecting the device /component to the controller
      If the component fits into a slot, see that the it is flushed in and not loosely connected.


  • Devices/components not setup properly
      Verify that the devices/components is being properly detected and setup in the respective controller setup screen


  • Bad connectors
      Replace the bad connectors with new working ones


  • Bad components
      Replace the component


  • Bad interface board or motherboard
      It is recommended that these components be replaced or that the computer be sent in for servicing


Hardware Failure: The big issue

The big problem, as
mentioned earlier, is not replacing or repairing the non-functional
hardware, but the time lost, interruptions to daily routine (especially
for businesses), and the loss of critical data. If you need a running
system at all times, have a backup system as a fail safe, or even two.
If users want to ensure that none of their critical data is lost in the
event of a hardware problem with their computer, there is only one way
to do it — Back up the data as often as possible.

There are many
different ways to ensure that the data is backed up, and as technology
becomes advances, back up methods become much simpler.

Let’s look
for a moment at what a back up is. Backing up of computer files means
that users are making a copy of the data that will be stored somewhere
other than on the computer. Everyone should always have a back up of at
least the most important files, because should anyone experience a
hardware problem, they could still be able to access the files.

Many
people don’t back up their files, because they don’t know what they
need to back up. Start with those files that cannot easily be recreated.
Then, move on to files to which you make frequent changes just in case
you accidentally change something that you shouldn’t have. Back up your
music collection – because this can be quite expensive to replace in the
event of data loss.

In general, best practice is to back up the files at least monthly and more frequently if users access the files regularly.

Computer Hardware Components And Accessories November 9, 2024

Computers
are made of different components or parts, collectively known as PC
hardware. Some of the main hardware PC units include CPU, mouse, display
screen monitor, hard disk, keyboard, CD drive, etc. You can buy a
computer from a branded company or purchase an assembled model through a
professional computer software person. Many a times, when some parts of
a computer get corrupted, you can also buy separate components from any
online or offline computer dealers.

Likewise
computer hardware parts also do include novel items such as scanners,
sound cards, internet modems and even digital cameras. But, every
computer has individual properties like RAM memory, CPU model details,
etc which may vary from other computers.

Let us study about some of the most important computer hardware parts:

* CPU-
This part is the brain of the computer. It is known as Central
Processing Unit and works as a processor. The most popular processors
are manufactured by Intel popular as the Pentium Chip model. Intel
processors are widely used all over the world by most of the computer
manufacturing companies.

* Mouse- This hardware
is essential for desktop models as navigational object, to click on
varied options, selecting different objects and accessing necessary
information on the computer screen. There are two main buttons in the
mouse, to be used to access info. Nowadays, you can find interesting
types of mouse in the market such as laser mouse or ball mouse. But,
they all serve the same purpose to help access computerised info from
the CPU.

* Hard Disk- This is a device that
helps in storing data. The all-round performance of any computer
actually depends on the speed of its hard disk. Higher rotational speed
of the hard disk enables fast and high speed performance by that
particular computer.

* RAM-
It is also known as Random Access Memory, which aids in storing of
temporary information in the CPU. When you switch off the computer, such
temporary info files are erased. The optimum performance of the
computer also depends on the size of its RAM.

* Keyboard-
This is one of the most important part in computer hardware. Keyboard
helps users to enter specific commands by punching of alphabets, numbers
or signs. There are other function keys like Control, Alter, delete, F
keys, Page up, Page down, etc in the keyboard. There are a total of 101
keys in any standard keyboard, and designed in such a way so as to make
typing faster and easier.

Other additional computer hardware
includes scanner, joystick, external drive, printer and servers. Buying
individual computer hardware parts can be a tedious task as there are
variety of selection models, styles and designs to choose from. It is
best to gather some basic first hand info about the specific computer
hardware part that you intend to buy.

You can choose to buy from
online computer hardware retail shops and other hardware dealers. Online
directories can help you sort a list of potential manufacturers or
retailers who are genuine and trustworthy.

How Static Could Ruin Your Trading Computer October 26, 2024


Your trading computer is vital to your trading day. Your PC is your
world. This means that maintenance and care of your trading computer is
crucial. There are lots of small things you can do to care for your
machine and ensure that the life span is optimized. One thing that
cannot be overlooked is the damage that static can cause to your stock
trading computer.


Typically, your trading computer will be built with the ability to
install more RAM or expand your internal components. Your builder will
do this by leaving open slots to install hardware later on. While this
is very convenient for you, you need to be armed with the knowledge of
how to accomplish this and what can go wrong. Static electricity
discharge can be a major enemy in this case. These shocks can severely
damage the internal components in your trading computer. This isn’t
something you need to normally concern yourself with. However, when
installing new components in your stock trading computer you should be
extra cautious of static discharge. Even your new components will be
packaged in antistatic bags to ensure that there is no static during
transport or while being opened. The biggest culprit here is that you
will not be able to notice visible damage to your RAM or new graphics
card. What will happen is the static will cause electricity overload
that can cause permanent damage.

The good news here is that it
is very simple to avoid causing this damage to your trading computer.
You can make sure that the static is discharged from your hand by
touching a piece of metal before handling any parts or working on the
inside of your trading computer. You can also leave your computer
plugged in with the main power button on the back of the computer turned
off. This allows you to have your machine plugged into a grounded
outlet, but not receiving power. This is very important to turn of the
main power in the back of the computer. Don’t just turn off the power
from the switch in front that you use regularly to power your machine
off and on. If you want to be ultra protected from static, you can also
get an antistatic wrist wrap or anti static mat. This works by placing a
wristband on one of your wrists and connecting this to your computer’s
case. Being connected to your computer’s case will allow you to be
constantly grounded from static. This is a huge advantage because you
don’t have to worry about discharging the static.


The point of all of this information is so that you are aware of your
options to solve static issues. You might get away with not applying one
or several of these suggestions, but you would be lucky to not have
caused damage. Your trading computer is an important part of your
business and income. Not something you want to take risks with.

A Brief Look at Computer Hardware September 7, 2024

Computer hardware is a device that is related to computers, and
it is in a physical form. Keyboards, mouse and monitors are examples of
computer hardware that we can touch. In contrast, software such as
Windows operating system is not considered hardware because it does not
have any physical form, nor we can touch it.

Examples

This
hardware is not only found in personal computers, but the term can be
attributed to anything physical which forms part of a larger computer
system or network. Nevertheless, computer hardware found in modern
personal computers include monitor, motherboard, CPU, RAM memory,
expansion cards, power supply, optical disc drive, hard disk, keyboard
and mouse. All of these components of a computer have physical form, and
anyone can touch them. For example, if someone has bought Microsoft
Office disc to install MS Word on their personal computer then it can be
stated that the disc is a type of hardware because it has a physical
form. In contrast, application stored inside that disc e.g. Microsoft
Word is not hardware because it only exists in a digital format, and
does not have any physical aspect.

New Type of Computer Hardware

Similarly, removable media devices such as CD-ROM
drive and CD-W are some common types of this hardware which are used to
store data, and large files. Nowadays, USB flash drives are becoming
much more common, and they are quickly replacing CD-ROM as preferred
hardware to store temporary data. In near future, other PC hardware
called solid state drive will replace hard drives because it contains no
moving part, and takes much less space. Thus, hard drives, USB flash
drives and solid state drives are some other examples of computer
hardware.

PC Hardware or Hardware: What’s the Difference?

Hardware
is a term used for physical objects of technology such as personal
computer, but terms like hardware and computer hardware are also
synonymous. Therefore, it is not uncommon to use terms like hardware and
PC hardware, interchangeably. For example, a CPU can be called either
hardware or computer hardware. Usually, anything physical related to
computers is called PC hardware. Otherwise, objects such as keys, locks,
door handles, electric wires, cutting tools, cutlery, machine and most
things made of metal are generally known as hardware, and found in
hardware stores.
