REASONS WHY YOUR PC FREEZES









Even if you are not a
regular PC user, you may at least once have experienced system freeze on your
computer. System freezes commonly occurs in lower version of Windows OS and
lower capacity PC. It also randomly appears even in the high end computers with
latest version of windows OS. 





When
a computer freezes, it removes your ability to control it, meaning that either
the keyboard or mouse doesn’t respond. There is also what's commonly called a
blue screen of death (BSOD), which also freezes the computer before shutting it
down. 


There
are several causes for freezes, and a few ways to prevent them. However, you
will always have to restart the computer when it freezes. 






The
reason(s) you may experience computer freezes, could be software related or
hardware related; perhaps it's a combination of both, so let’s talk about its
cause and how to prevent them.


  • A PC is set to perform within a
    norm and if the computing exceeds that norm, system freezes occurs. Even
    with regular system update of programs and hardware device drivers, if
    your computing exceeds beyond what your PC is set to handle, the system
    freeze occurs. That is the main cause of a system freeze!



  •  Another cause is that
    when a user installs programs or hardware device drivers that are
    incompatible.



  • Likewise if a software package
    is high ended but installed in a computer with smaller computing capacity.
    That is another reason.



  •  When temporary folder is
    full that its bloats up and over uses the disk space. Temporary folder is
    where all the temporary files needed by running software are saved in. For
    example: the internet browser saves all its files downloaded from the
    internet in the temporary folder.



  • Hard disk bad sectors as a
    result of overhaul. When a program or file that is located in the bad
    sector of the hard disk is loaded up, the system freezes up on you.



  •  The page file, which
    saves all the files as a cache, when bloats up.



  • When a system registry is cluttered
    and disorganized with too many invalid or wrong and unwanted items, it
    bloats up. A cluttered registry prevents easy access of file settings and
    thus a system hangs up as a result of executing these bad entries to get
    to the right one.



The
Remedy – How to prevent system freezes:




OK,
the kitchen sink is pushing it.. but you get the picture. Now that we know what
may cause your computer to freeze or lockup the real question is how to isolate
the cause and solve it. Now since there are numerous sites that address this
issue I have composed a list that should be helpful.





Before
installing a software package of hardware device make sure it’s compatible with
your computer.


  • Don’t install the programs that
    did not meet your system requirements.



  •  Use Disk cleanup tool to
    cleanup temporary folder periodically.



  •  Use Disk defragmenter
    tool to reorganize files into healthy sectors thereby fixing the bad
    sectors in the hard disk.



  • Adjust your page file size to
    what system recommends.




  • There may be several reasons
    why your computer may be freezing. First question is when was the last
    time you cleaned your registry. Having a corrupted registry can cause a
    whole host of errors and problems. Freezing up is one of them. If you have
    a lot of unnecessary registry keys that are hogging up your computer
    resources. Your computer is bound to choke. Scan your registry with a good
    registry cleaner. If you pull up more than 20 errors or duplication, clean
    your registry.



Besides
all those, consider some of these other issues.






Depending on your RAM specs and your computer usage. This could also be a the
issue. Having an insufficient amount of free space does not allow your RAM to
function properly. If you are using a lot of RAM by net surfing or other
activities without enough empty space your will get freezes. You don't need to
buy new RAM but you should increase your free space by removing unnecessary
data and perhaps increasing your virtual memory.


Spyware
could be the culprit, so do a scan and see if your computer is infected.



Another area is a hardware drivers. This could be the problem if new hardware
has been added to the system. So, the drivers should still be up to date. So
try the first two suggestion and see if you can get your computer to stop
freezing.


Check
your drivers.





Lastly,
check the dust buildup on the fan to make sure you system is cooling properly.





Trust me, in the
absence of those factors, Blue Screen of Death (BSOD) or system freezing will
be a rare incident to you.

TEN PROFOUND INNOVATIONS AHEAD



















Today's world looks increasingly like the future. Robots work
factory assembly lines and fight alongside human warriors on the battlefield,
while tiny computers assist in everything from driving cars to flying airplanes.
Surgeons use the latest technological tools to accomplish incredible feats, and
researchers push the frontiers of medicine with bioengineering. Science fiction
stories about cloning and resurrecting extinct animals look increasingly like
relevant cautionary tales.

 




But even the best of science and technology has yet to solve
climate change and famine, or conquer disease. More and more people live on a
planet with shrinking resources, which leads to political strife and conflict.
Here, we examine some of the hottest areas where researchers hope to forge a
better tomorrow.


 


HACK THE BRAIN


Much
of the human brain remains a mystery embedded in billions of neurons. Now
researchers behind the
Blue
Brain Project
have announced plans to create a
functioning, artificial human brain within the next decade. They have already
modeled part of an artificial rat brain using the IBM supercomputer Blue Gene,
and said that the simulated brain cells have even begun self-organizing without
human intervention. Success in reverse-engineering the brain could lead to a
model for biomedical testing, as well as a better understanding of human
consciousness. The researchers only caution that it's no
artificial intelligence ... at least, not yet.





HARNESS THE SUN'S FIERY FURNACE


Nuclear
fusion has kept the sun shining for billions of years. Now scientists want to
recreate that power on Earth and finally tap into fusion's unbeatable energy
efficiency. Giant lasers at the
National
Ignition Facility
could
help along that breakthrough by
focusing
their power
on a tiny hydrogen fuel pellet, and
ideally release more energy than what the lasers require. Still more
alternatives involve the
magnetic
confinement
of high-temperature plasma involved
in fusion, or even a rebranded form of
cold
fusion
. For now, LiveScience readers have already voted on their best
bets
for alternative energies.





GLOBAL CLIMATE CONTROL


Forget
modest goals like trying to
halt
Mother Nature
from raining on the Olympics.
Geoengineering plans befitting Bond villains have become hot topics for the
National Academy of Sciences, the American Meteorological Society and the White
House science advisor. Ideas include lofting
reflective
particles
up into the atmosphere to divert
sunlight and cool the planet, or seeding the oceans with iron to encourage
carbon-gobbling algae blooms. Even billionaire Bill Gates joined a patent
filing on an idea to slow or stop hurricanes, by deploying a fleet of ships to
churn the ocean and cool the warm surface water that fuels such storms. Climate
control technologies have almost become reality, which raises the question of
whether scientists and policymakers want to risk the
side
effects
of such schemes.





ELIMINATE WASTE


New
technologies look to turn all our trash into reusable materials.
Chicken
feathers
and other agricultural castoffs
could become the future of plastics. Biodegradable plastics that
dissolve
harmlessly
in seawater might actually
encourage people to throw their garbage into the ocean. Food scraps, sewage and
other waste has already
begun
to fuel
some power plants and generators
for the
U.S.
Army
and civilians alike. Achieving 100
percent sustainability may still sound daunting, but the efforts do add up. MIT
researchers have even begun a Trash Track project to gauge the costs and
patterns of waste disposal in New York, Seattle and London, in hopes of helping
more people think green.





FEED THE WORLD


Solving
world hunger represents an incredibly difficult task, given that the political
situations and economics of each region bring their own complications.
Nonetheless, scientists have moved to protect the important crops that feed
most of the world. Researchers continue to develop different varieties of
wheat, corn and rice that have
greater
yields
and are more resistant to
temperature changes, drought conditions and even insects. New
information
technologies
can keep farmers updated on the
condition of their crops and agricultural practices which preserve
nutrient-rich soil in the long run. Even
lab
grown meat
could help satiate the growing
worldwide demand, if people can get over the irk factor. And if all else fails,
scientists have stored thousands of seeds in a
doomsday
vault
to safeguard the future of food.





REGENERATE THE BODY


No
one has regenerative powers just yet, but patients can expect a growing array
of therapies to repair or entirely replace organs in the human body. A British
team grew the world's
first
artificial liver
from
umbilical cord stem cells in 2006, and other researchers have since found that
even the heart may
harbor
stem cells
capable of regenerating the organ.
Adult stem cells have also helped restore eyesight using a patient's own
healthy eye stem cells in an Australian study, and Chinese scientists
demonstrated the potential of adult stem cells by creating live mice from
reprogrammed skin cells. The future of individually-tailored organs and
therapies may soon arrive.





KNOW IT ALL


People
could eventually hold a hitchhiker's guide to everything that they see. Pick up
a carton of OJ in the supermarket, and nutritional comparisons about that brand
would appear. Flip through a new bestseller in the bookstore, and reader
reviews might flash on the pages. MIT has already
unveiled
a prototype
of such a technology in 2009, which
combines a webcam, a projector and a smart phone to link the Internet's vast
array of information with the real world. Such wearable devices would work
together with embedded "smart" systems and tags to create an
augmented
reality
, where staring at a street might bring up GPS coordinates
and a local map. In the 21st century, information reigns supreme.





A PERFECT ARTIFICIAL LIMB


U.S.
veterans and other prosthetic users may soon wield artificial hands, arms and
legs as easily as they control their natural limbs. The most advanced
prostheses tend to use "smart" microprocessors that act as tiny
brains to anticipate how a user will walk or move an arm. But
both
monkeys
and humans have already used brain
signals
alone to control robotic arms and
digital applications, which paves the way for new brain interfaces with
artificial limbs. Such technology could then retrofit the latest prostheses to
give users ultimate control over that "Luke





AROUND THE WORLD IN 90 MINUTES


Phileas Fogg took 80 days to go around the world,
but travelers may eventually hop halfway around the globe in less than an hour.
The U.S. Air Force and Brazil are developing a Lightcraft concept that could someday ride
laser-produced explosions into the sky, and deliver passengers or cargo around
the world. Barring that wild ride, space planes that could take off and land like regular aircraft
have begun undergoing serious development in the U.K. and United States, and some could fly within
the next few years.





READ MY MIND


True
mind-reading devices remain in the realm of science fiction, and lie detectors
rely on indirect cues to catch fibbers. Still, brain scans have allowed
neuroscientists to predict what people will do during specific task
experiments, and even to observe when a person will
make
a mistake
up to half a minute beforehand.
Another technique has used
near-infrared
light
to figure out simple preferences
based on brain activity. These feats rely on analyzing brain patterns that
occur during specific actions, rather than truly cracking the brain's neural
code, but they still have scientists and legal experts debating mind-privacy
issues. Perhaps in the near future, they'll just
use
Twitter
for a meeting of minds.

WHY OBINNA DOESN'T UNDERSTAND CLOUD COMPUTING










Recent survey shows that most Nigerians don't understand
cloud computing -- and it's our fault










In a recent survey carried out by Nimos
Technologies
, 85
percent of respondents claimed they have never used the cloud. Worse yet, 25
percent thought the cloud is a “fluffy white thing in the sky”.







As
we know, people who took this survey most likely do some online banking;
purchase from online retailers, post status updates on social networks, and
manage photos on photo-sharing sites -- all in the cloud. I'm sure many have
signed up for iCloud, Box.net, Dropbox, or other retail cloud providers, though
perhaps not understanding exactly what they are using.





The
problem with cloud computing is the term itself. It's way too overused,
covering way too many technology patterns. As a result, cloud computing has no
specific meaning, which makes it both difficult to define and to understand,
whether you're a cloud computing industry staff or an average Nigerian.





Mr.
David Linthicum of
InfoWorld once
state: "I believe we've officially lost the war to define the core
attributes of cloud computing so that businesses and IT can make proper use of
it. It's now in the hands of marketing organizations and PR firms who, I'm
sure, will take the concept on a rather wild ride over the next few
years." He further adds: “That was true a year ago, and it's still true
today”.





With the introduction of iCloud by Apple, the term Cloud
Computing has become very common. So the question still remains: “What is this
Cloud computing?” as a colleague of mind once put it.





Now think of the entire internet as a big cloud sitting out
there above the world. Wherever you go – you just need to look up to the sky –
and there it is.





Now think about having all your stuff floating on that
cloud.





Wherever you are, whenever you want it, all you need to do
is reach up to that cloud and grab what you need.





Suppose you want to share some of that stuff with your friend
halfway across the world. All your friend needs to do is look up to that cloud
and grab what they need, use it – maybe even change it, and put it back on the
cloud.





The next time you need that same thing, it will be there
waiting for you – with all the changes that your friend made to it.


In the digital world – this cloud can hold lots of things.
It can hold files. It can hold applications.





For example, if you use Google Apps for calendar, email,
documents etc. – you are using Cloud Computing.





For instance a friend of mine wanted some help setting up
her iCloud. She really didn’t know much about it, but she knew that she wanted
to be able to share some stuff, like calendars with her family. She wanted this
to happen on a personal level – not for business.





If you use Dropbox or Apple iCloud – you are using the
cloud.





This explanation is very basic – and behind the scenes as
proven earlier, things are more complex.





But from the perspective of the average end user – this is
how we see it.





And Cloud Computing is truly changing our daily routines,
how we work, and how we live.





Thus having the information that we want and need right at
our fingertips has become the new norm and believe me it’s here to stay.
