Computer Memory Tips- Free Interesting Facts For Computer Memory Price

December 4, 2015

Buying pc upgrades is able to be confusing. Purchasing computer memory is ready to be even trickier. But armed with the right knowledge, even the the majority novice pc user will be ready to get pc memory with confidence.

The pc firmware initiates a reset following saving the data; the personal computer technique determines whether a prevailing reset is firmware initiated; if the existing reset is firmware initiated, the personal computer technique copies the info at the 1st memory controller having the first memory controller to employ the first pc memory, and uses the first pc memory to initialize the second memory controller to employ the second pc memory; and if the current reset isn’t firmware initiated, the pc system generates the information that enable the first memory controller to use the 1st computer memory, and saves the configuration info in the memory space.

If you really suffer ever been trying to run two or three plans at once on your computer, and it appears to get exceedingly slow and sluggish, you actually may also suffer a pc memory issue. Computers suffer a pair of sorts of memory, and both also are exceedingly vital if you really accomplish many of your day’s activities on a personal computer.

RAM: We will be ready to upgrade the memory of the personal computer by the adding further RAM at the memory slots during motherboard during order to increase the overall performance of the computer. Random Access Memory (RAM) is the sort of info storage during the computer during which any storage location can be accessed directly. Both the size and capacity of RAM are reduce than the difficult disk.

Motherboards having 4 memory slots: A few motherboards suffer 4 RAM slots. So, we would believe that we will be in a position to attach four GB of RAM at the personal computer which will greatly increase the performance of the personal computer. Yes, we can connect 4 GB physically nonetheless a few of the of the 32-half operating strategies may also not supply the entire four GB RAM of memory to us in place it sets a part some part of the memory for internal uses and provides around 3 GB for us. Therefore, if we want to utilize all the memory slots for skyrocketing the performance the better choice is to connect two 1 GB memory modules to two slots and 2 512 MB memory modules to the remaining slots. Even if we add 4 1 GB memory modules to every of the slots we are also going to get the performance that is virtually same as three GB most effective. Therefore, we are also unnecessarily spending money on single 1 GB memory module.

Finally, the monitor is what you will stare at while using the computer. Broader and larger screens allow way more things to fit on the screen. LCD is the norm, 19 inch or bigger, large screen if practicable is what I recommend.

Iyogi Tech Support Review

October 30, 2015

I
am not a computer geek and this review is intended for people like me.
There are many technical support reviews examples on web that can make
you learn but most of them will not go any deeper than explaining
through examples. Recently I had to ask for some technical support from
iYogi for my PC and my experience wasn’t that bad. I give a huge credit
to the technician been provided to me.

The
review of my experience with iYogi technical support might be
worthwhile too. Their support options can be pretty affordable. Their
professional support “list price” is $ 169.99 for one whole year for
remote tech support. My experience isn’t necessarily representative of
the kind of support you will get but you will definitely get an idea how
does it work. All I can do is to educate people about the kind of
support you will get.

Without any notice I had this weird
freezing of my computer. I was almost in the middle of an important work
and suddenly my computer crashed. I called iYogi for help as few days
back I gone through their website and I found it pretty decent to ask
help from unlike other technical service provider (I don’t want to take
name though). The technician was pretty helpful and supportive too.

Tech
support has always been a huge burden for most companies. But all you
have to do is to browse through the net for tech support newsgroups,
iYogi has many of them, and then you can quickly realize that most
customers don’t even know how to put forward their questions. Mixture of
different computers and other things makes any sharp and talented
technician confuse and makes it impossible for them to resolve it.

Communication
with the customers has to be real supportive, which u definitely get
from iYogi. Technicians usually gets carried away with their
troubleshooting and sometimes cuts off the customers when they speak or
neglect their opinion of the issue because a user or customer only knows
what it’s really about. Aside from this, an employee or technician
should always be courteous and well mannered towards many customers
because that’s their area. They should also make the customers
understand about the troubleshooting so that the user gets familiar with
it.

A real good tech support person has a lot of knowledge and
training and it’s a valuable asset to ask for a good salary. iYogi does a
lot to protect that type of talent and provide the essential and high
quality tech support that some people need. To respond to this, iYogi is
taking advantage of the fact that there really are a lot of iYogi
people out there who are ready and willing and able to help the users.
Some of them are the nicely paid tech support people with whom you might
talk to on phone.

iYogi creates the website, etc that makes it
possible for people for customers or the users to communicate well and
for also selecting the right program or plan for themselves. Instead of
forgetting the websites that helped us out from the soup, I will suggest
you to make a bookmark of these websites, for issues are always around
the corner.

Since I went for the one year subscription plan, soon
I received a call from a skilled technician over the phone. Though it
took time for the technician to understand my problem but I still
appreciate that I didn’t get that scripted response what we usually get
for other free technical service provider, like after talking to those
you feel like banging your head against the wall in frustration. The
iYogi technician treated me like a customer but didn’t assume that I
knew nothing. This made it possible to zero in on what to do remarkably
quickly. After checking a few obvious possible ways, we set a remote
connection to my PC so that the technician could work directly on my
box.

The short version of my story is that, using emailed
instructions the technician got to me right after that, and made me
understand what actually causing the problem.

The enough good
knowledge that is been taught by my technician was that when the
computer cannot find an updated driver, it locks itself up and get
freeze. The hardware drivers should be updated on a regular basis. It
also helps in augment the computer’s RAM by increasing the PC’s virtual
memory. RAM acts as a buffer to speed up access to your programs and
files that are in use. Though all of your data is stored on your hard
drive, RAM is much faster. Whenever your computer pulls up a file off
the hard drive, it loads it into your system RAM so that it can continue
to access it faster. The end result is a much faster interface with
your computer. The more RAM you have the more programs and files your
computer can keep stored in your RAM.

Since this is a virtual
Basic site, I won’t be mentioning the brand name of my PC. If you are
absolutely dying to know email me I’ll tell you everything. The
technician updated my driver remotely and I’m up and cranking again on
my PC.

After
my whole remote session I have gone through their website minutely and I
learnt that they have around 95% of customer satisfaction. I will
definitely like to mention what iYogi is good at; employees of iYogi are
good at working under supervision or within a team. The technicians are
good natured personality and affable character and also help the team
morale and team work. The personal traits and the characteristics can
affect and individual’s output and team work much more than you can
imagine. And they also leave a mark on customers mind.

If you
roll your eyes towards the back of your head, you will realize that that
you are not alone in making complaints for their computer. There always
a tsunami of customer commenting on iYogi’s forum about their technical
support. There are few praising and few are disapproving, maintaining
all these by the technician and still giving you the satisfactory
solutions is an appreciable job.

These guys diagnose the root
cause of the errors with a device or hardware and if it can be resolved
by manual resetting then they will guide the customers through the step
by step process. They wait until the computer is restarted to ensure
full resolution of the issue.

After I finished speaking with the
technician I also spoke to his supervisor, to express how much I
appreciated my technician’s work. The technician has this amazing
knowledge of the situation, the courtesy and respect he showed and their
diligence in resolving my problem was extraordinary and most
commendable. I truly appreciated working with him, as I learned a lot
from them. He was a real trouper and quitting wasn’t a part of his
character. iYogi should be very proud to have this member of your staff
on your team and in your organization. It was a truly great job.

Getting
online computer tech support has various benefits. One is that you save
a lot of time and get you box fixed as soon as possible. Another
benefit is that through their PC tech support guidance, you get some
training on how to fix the computer issue. In case the same predicament
happens again, you would know what to do to fix it. There by saving you
the costs on computer repair tech services.

I will also mention
it’s amazing to get their 1 year subscription plan from iYogi, for which
you have to pay once $169.99 and they provide you with the best
technical support free of cost of whole one year. You have to make sure
that your computer get the support maintenance and true tune up, it
needs to perform well.

What best you can get customized technical
support services at the time and place you want and at anytime 365
days. With the overall PC troubleshooting (as technicians call it)
experience of around a decade, they not only gives you a deal on tech
support but also familiarize you with the workings of your darling
machine.

The community is always willing to lend an extra hand,
with discussion boards and Q&A services, forums, troubleshooting
support may not be real time or hands-on, but it is free and
instructional.

The bottom line is that, in at least this one
case, iYogi official technical support justifies the price as mentioned
on their site, and provides you with the best technical services round
the clock.

A Brief Look at Computer Hardware

September 16, 2015

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.

Understand Your Computer Hardware

September 15, 2015

Computers have become an inseparable part of our culture and
we cannot think of a life without computers. They are everywhere; from
the calculator in your pocket to the space-ship that landed on a moon,
from mobile phones to the satellites, from the desktop PCs to the
supercomputers, from sports to industries, and from our kitchen to the
white house; they perform countless functions. To understand your computer hardware, you do not need to open the cabinet of your PC, you can start with the basic of computer hardware.

What is Computer Hardware

Computer hardware
is a set of devices that are interlinked to get the tasks done by the
computer. For computers to run, both hardware and software are required.
Software are the automated programs that help us to communicate with
the machine and get the results.

Motherboard

Motherboard is a word used in reference with a board that holds many computer hardware partstogether.

CPU: Central Processing Unit is the brain of your computer system. It shows which generation your computer belongs to.

RAM: Random Access Memory is an internal memory that all the input and output functions make use of, while dealing with the CPU.

Motherboard also holds chip set, BIOS (Basic Input Output System), and ROM (Read-Only Memory).

Power Supply Unit

PSU converts AC (Alternating Current) power to DC (Direct Current). It supplies this power to CPU, Hard disk, and cooling fan.

Data Storage Devices

Hard Disk:
It can store data up to 1 TB (Tera-bytes). It is one of the devices
that lasts long. Nowadays, you can also get detachable hard disks in the
market.

Flash Drive: Sometimes known as a pen
drive, flash drive is a detachable and very handy storage device.
Because of its size, which is not more than the length of your finger,
flash drives are very useful when it comes to storing and transferring
small amount of data.

Memory Card: Nowadays,
with the advent of mobile phones, the use of memory cards have become
imperative. They are the smallest in size and can store data up to 8 GB
to 16 GB (Gigabytes). Computers have inbuilt devices called card readers
that can read and write the data on memory cards.

CD/DVD (Compact Disk/Digital Video Disk):
These are other modes of saving data that is cheap and easy. They are
re-writable devices, which means the data can be erased and written
again on them. Popular media output, such as movies and music albums,
come in these forms.

Magnetic Tape: They are used very rarely and make use of magnetic properties to store the data.

Input Devices

Input
devices allow us to feed instructions in a computer. We give
instructions to the computer to get the desired result or an output.

Keyboards: Theyare used to enter text and numbers. It also has other functions that enable us to manipulate data efficiently.

Mouse:
It is a pointer device that is used to point at graphical icons or
images, for selection and manipulation. With the advent of graphical
user interfaces, mouse devices have become inseparable from the computer
system.

Output Devices

Output devices are the means of getting desired results in various formats.

Monitor: It is the most important device that generates video output

Printer: It is an output device that allows us to take a print of the text and the images from our computer on a paper.

Speakers: They generate audio output

Every year, the number of devices increases to match the innovation in the software industry.

Make My Computer to Run Faster

May 17, 2015

The
amount of memory your computer has a significant impact on your PC’s
performance. I am referring to RAM (Random Access Memory). Your system
RAM can be viewed by right-clicking on “My Computer” and then choosing
“Properties”. In the General tab, there is a section named Computer that
will have important information about your computer, including the
amount of RAM. However, PCs with 512MB or less of RAM, can get a very
improved performance by taking the recommended steps outlined below.

Tip
1: Startup Items – The number one cause of poor PC performance is
excessive memory usage by unnecessary programs in your startup list. You
can view these items by going to Start->Run. Type in msconfig, press
enter, then go to the tab Startup. All the entries with a check mark
will load when your computer is started. The best way to speed up your
computer is to uncheck the unnecessary processes. In general, the less
RAM your computer has, the fewer startup items, you want to have.

Tip
2: Spyware – The next thing to do is eliminate spyware and so-called
computer hijacking software. I recommend Acebyte Utilities Free.
However, if you are trying to minimize startup programs to save memory,
you could just run the program at regular intervals.

Tip 3: Virus Protection – You can look for a free anti-virus program without all the bells and whistles.

Tip
4: Windows Clean-up – A good program for cleaning up general
inefficiencies such as temporary files, internet explorer files,
registry errors, and set startup items as described in Tip 1 is Acebyte
Utilities Free. This is good alternative to the Control Panel for
uninstalling unwanted programs, such as internet explorer toolbars, etc.

Each
of these steps should be repeated at regular intervals based on system
performance. Also, be aware that in addition to steps above, the number
of programs opened by you will also utilize RAM and slow your PC. So,
make a good habit of closing programs that are not in use.

About
Acebyte
Inc. was established in Jan, 2010. We have an ambition to improve the
experience of PC users (exclusively on Windows operating system). We are
mainly focused on designing PC optimization software for further
improvement of your system performance.

My Computer Is Not Responding! – Troubleshooting Computer Not Responding Problems

May 12, 2015

Computer Not Responding? When you try to open My Computer, IE, Firefox, Windows Media Player or other programs, suddenly it does not respond! Or when you are working or playing games on your computer, it freezes up for no reasons and programs are not responding. Why does this problem happen?

RAM and Virtual Memory

Normally this problem happens because of your running too many applications at the same time. If you run over 10 plus programs, this will lead to your inadequate RAM situation. Then some programs do not respond because of not being allocated enough RAM resources. You can increase your RAM or Virtual Memory to avoid the not responding problem. Follow the steps bellow:

1. Open Control Panel. Then double click System on the opening page and then click Advanced tab in System Properties window. Then click Settings in Performance area! And click Advanced tab in Performance Options window. Click Change and the Virtual Memory window opens.

2. Select the drive which Paging file is set. And click Custom size and change the size of page file. Initial size should be 1024 MB at least & max size should be not less than 2048 MB. And click Ok.

Then you successfully increase the Virtual Memory of your computer! But you need to check the your system below.

System or Program errors

If your RAM is more than 1 G but your computer is still experiencing not responding problem frequently, then the problem probably results from system or program errors. A lot of factors can lead to it, such as corrupt registry keys and values, Dll files and so on. They are very import to System performance but very fragile. When you use a computer after a long time, they are probably damaged and cause computer freezing, not responding, slow computer problems. It is vital to maintain your computer regularly to avoid and fix those problems.

How Static Could Ruin Your Trading Computer

April 13, 2015


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.

Diagnosing And Troubleshooting Computer Hardware

March 28, 2015

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:

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.

Getting Cheap Computer Parts For Your Assembled Computer

December 17, 2014

Changes in technology have made it difficult to work without a computer. When you use a computer you can complete even the most complicated task without much difficulty. Most people consider a computer an essential part of their life, and it has made their life simple and easy.

Advancements in technology have changed the features and the capabilities of the computer. Today, there are many models of computers available in the market depending on the configuration and budget of the consumer. There are many retailers who sell cheap computer parts, which has made computers more affordable.

Earlier, people found it difficult to get a variety of parts in the market when they wanted to assemble their computer. Even if people were able to find the required parts, there was always a risky element involved in buying those parts. Most people who were aware of the availability of the parts did not know how to use them, as their professional knowledge was limited. Today, competition and changes in technology have forced manufacturers to sell cheap computer parts, which can be used by consumers to assemble cheap computers.

These days the internet has made it easy for people to buy inexpensive computer parts from an online retail store or at auction. Most people who have professional knowledge on how to assemble their computer can take advantage of this opportunity and get cheap durable computer parts. By assembling their own computer, people can save money as ‘branded’ computers are expensive. The prices of most computer parts, such as motherboards and CPUs, have dropped drastically; this drop has not been reflected in the price of branded computers. The main reason why branded computers are still expensive is because the manufacturers of branded computers have high profit margins. This has forced people to assemble their own computer by buying the required computer parts from the market.

Some of the essential parts that people assembling their computer will require include the motherboard, the CPU, RAM, CD Drive, AGP card, Sound Card, Keyboard, mouse, hard drive, cables and adaptors. Some people may also require a printer and flash memory, but these are not very important and can be bought later. Some people who buy computers for their gaming requirements may need a Joystick and a high end Graphics card. You can buy most parts from online retailers either individually or together. Some retailers give you a good discount if you purchase all parts from them. It will be prudent on your part to compare the prices charged by various online retailers before you make your purchase. Some online retailers will also provide you with a step-by-step guide that will help you build your computer without any problems.

Most computer parts manufacturers manufacture items in batches to meet the requirements of branded computer manufacturers. Some stock that is unsold is off loaded to computer dealers at a huge discount. Computer parts available from the dealer are genuine and similar to ones found in branded computers. So next time you go shopping for computer parts you don’t have to worry about the quality of parts available in the market.
