Things To Consider Before Buying A New PC

o it’s about time for you to finally upgrade your computer, but
wait, what details should you look for while shopping? This article
is not for an IT student or a computer science major; this article
aims to help the computer illiterate into making a choice that he or
she won’t regret. Most of the advice in this article can be applied
to both desktop and laptop computers.

While at the store looking for your new computer, make sure you ask

and search for any warranty options that may be available to you. Not
only search to make sure that the computer you’re interested in has a
warranty, but also make sure that it covers as much as it possibly
can. A limited warranty that only covers an overheating part won’t do
you much good when you spill coffee all over your laptop. It’s
important to note that many computers come with a one year limited
warranty that covers basic damage, though many people don’t feel safe
enough with this warranty.

Prioritize RAM

If you’re looking for a basic computer that will let you: play music,
let you surf the internet, and run most applications then RAM (Random
Access Memory) is your best friend. With new operating systems such
as Windows Vista becoming the standard, RAM is increasingly more
important so that you don’t feel that clunky slowdown. An ideal
amount of ram for a Windows Vista machine is 2GB (gigabytes). While
processor speed and hard drive space are important, they are usually
not as big of a factor in small end machines and therefore won’t be as
important to you.

Your Needs

What are you using this computer for? This is a question you should
constantly ask yourself when buying a new computer. If you’re buying
a machine just to check your email, then you don’t need the best and
most expensive computer parts to achieve your goals. If you’re trying
to build a machine that can play top of the line video games, or run a
large amount of applications at once; then it’s then more important to
invest a larger sum of money on your video card (GPU) and processor
(CPU) units. If you’re unsure about what parts will fulfill your
needs, you have many options to educate yourself. Ask the store
specialists, search online blogs and articles, or even asking an
online forum will net you a sufficient amount of answers to any
questions you may have.
Remember when buying a new computer to always think of what you will
be using the computer for. This will help you not end up with a
machine that is less than what you needed, but it will also help you
not to overpay for a machine that offers much more than you wanted it
to.

How to Fix Your Busted Monitor

eyond repair? Here are some things to consider when buying a computer monitor:

Resolution

LCD (Liquid Crystal Display) or CRT (Cathode Ray Tube)? Confused yet? You’re not alone; buying a computer monitor can be a daunting task for someone who doesn’t understand what any of the above terms mean. Monitors are much more than meets the eye, and while the market may seem oversaturated with seemingly similar monitors, there are key differences that should be noted.
CRT or LCD
Whether a monitor is a CRT or an LCD is the easiest thing to notice when you’re purchasing your monitor, as CRTs often have backs and LCDs are flat. Being flat, LCDs weigh much less than CRT monitors, making them ideal for transportation or for those who need to fit a monitor into a small space. In terms of cost however, the CRT wins hands down as its older technology and less desirable design makes them less sought after. It’s important to note however that LCD monitors come down in price with every breathing moment. One advantage that CRT monitors hold against LCDs is their color rendering ability. Many graphic designers and artists feel that the colors presented with a CRT monitor are of higher quality, which is true in most cases. LCD color quality is quickly improving, however, and it’s hard to tell if the CRTs will hold this advantage much longer.

Response Time

Response time, or refresh rate, refers to the ability of the monitor to update the color that a pixel must represent as quickly as possible. It’s actually so quick that this quality is measured in milliseconds. So why does this concern you, the buyer? Response time is very important for people who’re playing video games, as they require a quick response time, as well as video editors. High response times can cause more than lagging your game though because bad response time is often seen as the cause for image ghosting and blurring.

Your Needs

The most important thing to consider when purchasing a new monitor is what it’s that you actually need. If you play video games then you may want to spend extra time looking for a monitor with a high response time and resolution. On the same note, people who just check their emails need not worry with things like a high response time. It’s also important to note what kind of connection your video card uses and what kind can fit into the back of the monitor. Messing with converters can be annoying!

Buying a Monitor can seem like a challenge for the computer illiterate, but it’s actually quite easy with a little help. Make sure to talk to a store expert if you find yourself in a jam, and consider your needs so that you do not pay for pointless extra features.

How to Fix Your Computer Wire Issues

As technology has continued to improve, so has the wealth of options available to us for keyboards, mice, and other accessories. One of the biggest changes in this new age is the increased accessibility of wireless technology. Just because new technology is wireless though, doesn’t mean that it’s necessarily better. This article will outline the pros and cons of using wireless technology and hopefully make you make a decision on which you should use.

Wired

The older and more available wired technology is often praised because it’s extremely reliable and responsive and is less likely to stop working in a crucial moment. With USB mice, all you need to do is ‘plug and play’ and your mouse is already ready to go and you can begin to use it. The reason a wired mouse is less likely to stop working is because it doesn’t require batteries or a charger like a wireless mouse does, meaning that it will never go out on you unless the cord is damaged or the mouse completely dies. Wired mice are also much more responsive than wireless mice because they don’t experience a wireless delay, though this is likely to change as technology improves. One reason that people don’t like to use wired mice is the hassle of having another cable. Wired mice often have non-tangle proof cables that become a hassle in a small space and gather dust. On the other hand, your cable might not even reach the desired length to your computer meaning that you have to go out of your way to make sure you can use your computer.

Wireless

Wireless mice and other accessories are a newer development when it comes to personal home use. One positive thing about wireless technology is its portability. There is no need to struggle with cords when all you need to do is hook in the mouse and use it wherever you please. This portability makes wireless mice extremely popular with laptops, as many people don’t like using the laptops touch pad. Wireless technology is also praised for its USB connections, which are the most common connections in new computers. While the new wireless technology has some extremely practical applications, it is not without its faults. Wireless mice are often less responsive because of the delay they suffer traveling over a wireless network, as well as the fact that being wireless causes them to use batteries. These problems are likely to change; however, as ever improving technology solves these concerns.
As of now it looks like wired connections have a vast majority of advantages over wireless technology. Many of the problems that wireless technology faces, however, can be solved through ever increasing technological advantages.

How To Fix Your PC’s Overheating

Overheating is a serious issue with PC’s today, especially with
the new powerful graphics cards and processors on the market today.
It’s no coincidence that more and more fans and liquid cooling options
have emerged, it’s very common for your computer today to shut itself
off to protect you from the damage that overheating can cause. How
can you prevent the overheating from happening though? This article
will give you a few surefire ways to prevent your PC from overheating.

Clean Your Computer

That’s right; it could be as simple as cleaning. Clearing the
dust out of your computer is one of the best ways of decreasing the
heat that your computer is putting off. Dust can accumulate to a
point where it slows down the speed of computers fans, and it even can
stop them! You can’t stop dust from getting into your computer
either; even if you leave the computer case closed dust will still
find its way into your computer.
When cleaning your computer it’s important to remember to turn it
off. This ensures that the fans won’t be moving and that you won’t
cause any unwanted damage to your system. It’s also important to know
what areas you’re looking for. There will be a fan on your CPU, your
power supply, as one located on the back of the side of your case.
There are many ways to clean these fans off but one that’s often
recommended is the use of canned air.

Reduce Overclocking

Overclocking is the term used for when you’re running a computer
component at a higher speed or rate it was intended to run at.
Overclocking is more popular among high-end and gaming PC’s, so if you
didn’t know what overclocking was it’s safe to assume you’re not doing
it.
Overclocking not only decreases the life of the component being
overclocked, but it also increases the temperature that the part runs
at tremendously. Therefore, if your computer is having overheating
issues, it’s never a bad idea to investigate if there is any
overclocking occurring within your PC.

Control Air Flow

It’s important to make sure that your computer has room to breathe.
If you’re cramming objects against the computer or putting it inside a
desk, you will cause it to retain more heat that it normally would.
You should also pay extra attention to the cables inside of your
computer. Many manufacturers let them run wild inside your computer,
which could mean that the cables are rubbing against other parts of
your computers or even slowing the fans down. This can easily be
solved by organizing them with Velcro cable ties.
Computer overheating is a serious problem, but it almost always
has a direct cause. This article outlines a few tips that should get
you on the right track to returning your PC to its intended
temperature level.


If you’ve ever worked with a computer extensively, you’ve
probably experienced every single one of these problems at least once.
Computers by nature become outdated and will have to be worked on to
fix the common problems that occur during their life cycle. This
article will address the three most common computer problems and how
you should go about fixing them. If you’ve had any experience at all
with a computer, you’ve probably at least seen one of these issues.

1. Computer Speed and Performance Slowed.

This is probably the most
common complaint that users have with their computers today. There
are many reasons why computers slow down overtime, but the most common
reason is lack of proper housekeeping. If your computer has slowed
down, try to remove any programs you don’t use anymore. It’s also a
good idea to clear the recycle bin and clear out any temporary
internet files that you may have retained. It’s also extremely
important to make sure that you don’t have spyware or adware on your
computer, so run virus/spyware checks often. If none of the other
fixes seem to increase your computers speed, try to defrag your
computer.

2. Computer Keeps Rebooting.

This problem is usually associated with
overheating or faulty hardware. If your computer is overheating, the
computer will recognize that there is a problem and shut it will shut
itself off when it reaches an unsafe temperature. You must first
identify what’s causing the computer to overheat. Make sure that your
computer has plenty of ventilation room and try cleaning the insides
out before restarting. If the above didn’t work, make sure you’re not
overclocking any parts, and if you’re not try to install new methods
of cooling within your computer. If all else fails consult an expert
about possibly diagnosing the specific part and replacing the problem
altogether.

3. Blue Screen of Death.

There are almost an infinite number of
reasons that you could be seeing the blue screen of death, so it’s
very hard to recommend a course of action. The most standard actions
you should take however, is making sure you don’t have a virus by
running a virus scanner and removing anything suspicious you may find.
If this does not solve your problem, it’s time to call professional
support, as it could be something very minor that only an expert could
handle.
Most of the problems mentioned in this article can be prevented
by maintaining good house keeping with your computer. Remember to
keep your virus and spyware applications up to date and contact tech
support if you feel any problem is out of your grasp.

How to Fix Your Printer


3. Consider Brands and Companies- It’s always important to note where you’re buying your technology from, as some companies are more reputable than others. You not only want a good value from the company you look at, but you’re also hunting for good service and support for once you’ve actually acquired your printer. Prices on Amazon or from company websites are often cheaper than buying them in a retail store, making online purchases from a company more desirable.
If you get nothing else out of this article, please take away with you that it’s important to consider what you need when you purchase new technology. If you get more features than you’ll actually use, then it’s apparent that you overpaid for your printer.
