Strategy for Hardware Upgrade

1. Types of Connections

The first question that you’ll need to focus on is the type of connection your system supports, including the monitor and video output. Sometimes, a video card or motherboard specifications might deny your monitor selection, simply by stating or showing an error related to unsupported computer parts. The two most common connection types for monitors are:

• DVI connectors: These are used as a digital output for PC monitors, and it supports all the modern video cards including DVI video cards and HDMI cards.

• VGA connectors: VGA connectors are generally paired up with an older PC that might not even install a video card or support DVI standards.

2. Screen Size

There is no standard phenomenon behind selecting an ideal screen size as it entirely depends on the user’s preference and personal choice. Cost of the PC monitor also plays a vital role in deciding the screen size.

Following are some of the guidelines you should check before buying a monitor:

• Larger monitors are better for graphics related purposes like watching or editing video, playing graphics intensive video games or giving final touch to your digital photographs

• If you’re looking for a completely productive setup, then use normal-sized multiple displays to finish up numerous tasks within stipulated time-period

• If you don’t use the PC regularly, then you may not need a large display

3. Native Resolution

Modern LCD monitors support pixels technology to provide amazing video and picture quality to its users. Analog CRT monitors can easily use lots of different resolutions without losing the exact quality of an image or video. LCDs employ pixels at fixed points, and this arrangement of pixels combines to make the native resolution of the display.

Consider the following factors to select an ideal computer upgrade:

• Always select a monitor with a high native or recommended resolution

• Ensure that your selected computer components deliver the best possible video quality

• Farsighted users may prefer PC monitors with smaller native resolutions to read small text easily.

4. Brightness and Contrast Ratio

Monitor brightness and contrast ratio can impact the actual functioning of major PC parts and is usually not something that interests a user. Computer screens offering a vast difference between brightest white and the darkest dark settings can be highly dangerous for naked eyes. So keep the following parameters in mind while selecting optimal brightness and contrast ratio of your hardware upgrade for PC monitors:

• Grab a monitor that rates greater than 200 cd/m2 on brightness

• Brighter monitors allow better display of color and better contrast ratios that are ideal for graphics professionals, video editors, and other professionals

• Always avail a device having contrast ratios higher than 350:1 and you can easily find PC monitors at reasonable prices with 1000:1 contrast ratio

• Try to search for monitors supporting Dynamic Contrast Ratios or Advanced Contrast Ratios to enjoy optimal video experience

5. Colors Display

Usually, all computer monitors and displays are capable of producing a full array of 16.7 million colors (24 bit), which is possible by using the entire shades of an RGB colorspace. Some older VGA monitors may not display all of them and only work in color modes having density lower than 24 bit. Old VGA monitors aren’t in style now so replace them with the new DVI monitors that possess all the capabilities to support 24 bit color schemes.

Need Fiber Optic Networks

A fiber termination kit is very handy for fiber optic termination as well as for splicing and testing purposes. These kits are essential parts of any fiber optic expert since it helps make their job much easier.

You want to make sure that you get a kit with all the right instruments. You will be needing electrical tape, kelvar scissors, a set of screwdrivers, tweezers and pliers. That’s not all, you might also need safety glasses since you do not want to damage your eyes It is always better to come well prepared in advance to prevent any accidents.

Another handy thing that comes in a good fiber termination kits is a black marker for creating precise marks, this prevents mistakes. Also, an emergency lamp is also something to keep by your side.

There are a few more tools that come in such a kit but we just mentioned the main ones. All of these tools come in a hard plastic tool case that is easy to carry around and durable. This way, you will not worry about dropping it during work.

A fiber optic tester

In order to test fiber optic networks, you will need to have a good quality tester. These equipments come in a variety of models. These testers are for checking the length, fiber loss, locating events on the cables and other characteristic of the fiber.

An important feature of a good fiber optic tester is a screen whose results are visible even outdoors. This type of screen makes reading the results convenient. The tester also needs to be durable and moisture-proof so that it can function even in wet weather.

Computer Case Cooling

The first tip you should take into consideration when it comes to computer case cooling is to ensure you buy a fan filter assembly that is bigger than required. Ideally buying a larger fan and allowing it to run at a slower speed will provide you with the same ventilation as a smaller fan running at optimum speed. The main benefit to choosing a larger fan over a smaller fan to ventilate the same area is it will be considerably quieter.

Always use a fan filter. Taking advantage of a fan filter assembly for your computer case can save you headaches in the long run. In addition to reducing the risk of a child in the home injuring themselves by sticking a finger in the fast moving fan, the fan filter also reduces any dust and dirt getting inside the computer. Computer components work best when they are clean and cool, which is what these products provide, ensuring you always have a great performing machine you can rely on day and night.

It is imperative when you install your fan filter assembly that you mount it correctly. Even if you think you know what you are doing, take the time to follow the instructions to the letter. Correct mounting reduces the risk of noise. As you know there is nothing worse than trying to work with a computer droning in the back ground.

When you look at your computer case, plan where you want to put your fans. Most cases come with areas ready to take on new fans, some you have to plan the design yourself. Ensure you have at least one in the front and back, maybe one on the side, depending on the layout inside the case and where all your components are located. You will need to ensure that air is drawn into the case near your graphics card and hard drives, which can heat up quickly. The air should then be drawn out on the other side, pushing any excess hot air out of the case. This will ensure that everything is kept cool at all times, enabling your computer to really work at its best without fail.

When it comes to buying fan filter assembly components you don’t need to break the bank. In fact these are affordable items that come in a variety of different brands and sizes. You can measure the space you have available to identify the best option based on your particular needs.

Don’t fall into the trap of buying the cheapest option on the market. You can find that some companies will offer the same or similar fan filter assembly for a fraction of the cost. As with any product you buy, you want to focus on quality. A high quality fan filter assembly is going to last longer and provide you with all the benefits you need to have a great working computer for years to come.

Renew Old Computer

Steroids for CPU

While some computers don’t have the option to upgrade their processor unit and graphics card, you can always work around tweaking its processor.

Overclock it.

If you are adventurous enough, you can try overclocking your processor. It’s one of the best way to squeeze out more performance without breaking the bank.

Monthly Clean Up

Before you jump to conclusion, you may want to troubleshoot your computer and make sure the slowness is not caused by malware – viruses, worms, trojan horses spyware or adware.

Do a full computer scan with your antivirus software like AVG, Symantec or McAfee. Also, you can clean up temporary files, update windows, and defrag your hard disk.

If all else fails, don’t despair, you can try to reinstall your operating system from scratch.

Speed up Your Applications

Even when it sounds weird to be true, the truth is that some good programs are not optimized to run at their peak performance.

For example, if your web browser loads slowly, it could be due to its history size, installed extensions, or plugins.

The Older Versions

If your hardware doesn’t support the latest version of a particular application, like Photoshop CS5, use an older version instead. While running older software isn’t always the best idea, if it can still get the job done, you will get lesser frustration and time wastage.

Deal with Your External Components

Besides their superior performance, brand new computers offer the fresh feeling of owning it, like a brand new car. New mouse, keyboard and speakers. These are the items which you can replace easily, without breaking much of a sweat. Sometimes all you need to do is to just buy new external parts.

Replacing Toner Cartridge Chip

What Happens When the Toner Cartridge Chip is Misread?

Cartridges could still have enough toner in them for printing if we refill them, and if the chip isn’t reset or replaced, warning signs continue to appear. The printer may refuse to print a page. This is because the computer is informed by the toner chip, and does not recognize that there is fresh toner in the cartridge. We can remedy this problem by replacing the used chip as this resets the counter.

Refilling and Reuse of the Toner Cartridge

The cost of replacing original printer cartridges is high and there’s a cost saving for us when a cartridge is refilled. The negative impact on our environment is also reduced when a toner cartridge is reused. Cartridges are made up of delicate parts including base metals and plastics. These represent costs to our environment in manufacturing and when a cartridge is thrown away instead of being recycled.

Reducing the Negative Impact on our Environment

Replacing the chip is of great advantage to us because it allows the refilling and reuse of printer cartridges without annoying printer messages popping up on the desktop. A second advantage is the overall reduction of human impact on our environment. The simple process of refilling cartridges and replacing the toner chip to allow reuse significantly reduces hazardous landfills.

Ensuring Quality in Your Toner Replacement

Toner cartridge chips are affordable and chips that are a perfect match for many types of printer can be purchased online. It is vital to make sure you choose a toner chip manufacturer with a good reputation and also that you select a provider that is known for quality refilling processes. Certain chip manufacturers display excellence in their chip development processes, taking care to reach consistently high standards.

How to Replace a Toner Cartridge Chip

Once you’ve refilled and cleaned the cartridge, locate the chip slot on the back or bottom of the cartridge. Some chip covers have screws and those may need to be removed first. Remove the cover and replace the old toner chip with the new one, being careful to align the circuitry correctly.

All about Routers and Ports

Routers are another important part of technology that has developed well. They are in every electronic store you can imagine. What an advantage it is that we can have a device that organizes and protects our internet use. When your computer browsing different websites the router will send traffic to and from where it’s needed. At the same time using encryption to protect your information from hackers.

There are many scary moments of where someone personal information was stolen. But the bringing of WEP and other protection methods of internet use has been a great way and advantage to the PC user. Being on a personal home PC should be a safe experience.

There are some who have enough experience and know how and when to loom for computer security attacks. Having a computer ramped with hackers and spyware can be very uncomfortable. That’s why routers, antivirus software, and other security measures are good.

One great security we have that comes with routers is the ability to have port selection. Every router has the ability to have certain ports that can be open and closed. Make the ports that you use for friend gaming closed and only open to your friends.

Playing games or having a chat with friends only to have someone hack in would be sad. What a bummer if one didn’t know as well. Playing games and having other pc activities done through a router and ports can be a very pleasant experience. As it cuts down on lagging from so many wanting to connect and interact with others online.

Clean Printer Rollers

Internal Pickup Rollers – For Laser Printers Only

Step 1

Turn off your printer and unplug all the cables. Uncover the printer’s front door and gently pull the printer’s toner cartridge towards yourself to detach it from the printer.

Step 2

Try to locate the printer’s internal pickup rollers. Rollers are either black or gray in color and are made up of rubber. Slowly lift the rollers in the upward direction towards the front of the printer. Now, pull out the rollers and place it on a smooth and clean surface like workbench or desk.

Step 3

Pour 1 tablespoon of water or isopropyl alcohol onto a lint-free cloth and begin the cleansing task. Fold the clean-up cloth in half and repeat the process until the rollers are free from dust and debris.

Step 4

Clean the rollers with a dry clean-up cloth to eliminate remaining dust or debris particles. Let the rollers dry completely before placing the pickup rollers back into their place. Now, properly reinstall the toner cartridge and close the printer’s front door.

Great PC for Gaming

System Case

You can get a desktop PCs in various sizes and shapes. Computers with a bigger case allow you to get several larger graphics, more hard drives, and sophisticated cooling arrangements. The most important part is the design of the motherboard, which gives numerous features. The limitation of such large cases is the fact that they occupy a lot of space and can dominate rooms of small sizes.

The number of computers having smaller Micro-ATX and Mini-ITX motherboards is increasing gradually. Their size is quite manageable. However, these are not adequate for users who like to double these up for graphic cards, or fit a larger quantity of internal parts, though they remain almost as powerful as their bigger cousins.

Graphic Cards

Of the internal components contained in computer’s case, the most significant for games is the graphic card. The biggest graphic cards are unlikely to get fitted into all cases. But generally, you should choose the most powerful card that your budget allows, as this component plays the most significant role in the way games perform.

There continues to be a strong competition with regard to price, the selection of graphic cards, plus advanced architectures among nVidia and AMD. The scales so far continue to swing among these two.

In case of gaming PCs, don’t ever be sparing when it comes to graphic cards. Though these components are the costliest, they are the most significant for gaming. Do not hesitate to go for a somewhat slower processor at the cost of a superior graphic card. On the whole, you should think in terms of matching their performance to steer clear of jams, and derive the most out of the two.

The Processor

Though the gaming experience is dependent on the graphic processor, your PC essentially requires its central processor. Even though most of what is available in the market comprises of the same basics, there is difference in their speed of using the memory, the selection of SSD and overclocking.

Use Mac for Business

That said there are a lot of times when Apple Mac computers are better for business. Any time you have graphic design involved for example. Mac computers dominate this industry with their large high resolution screens and amazing graphic software. Almost every web design, printing or graphic design company I’ve been in use Mac computers exclusively.

A Mac computer is also a good choice for a small one or two person office simply because they are so versatile out of the box. If you’re a small business owner without many staff the answer to “Should I use a Mac for my business?” might be a solid yes. You’ll be wearing many hats in this case including designing your own logos and marketing materials or maybe even creating your own website all of which Mac computers are very good at.

With the release of Microsoft Office for Mac, you can still use Outlook, Word, Excel etc which makes it easier for those making the switch. There is certainly a learning curve involved, however, as the operating systems are quite different but the basic concepts like files, folders, copy, cut, paste, and the like are the same.

Being an IT professional I get into a lot of different offices running a lot of different businesses. I’d say 90% of the time they are all Windows based. Microsoft still dominates the business world by far. I will say though, I’ve seen an increase in the adoption of Mac and we are getting more and more orders for Macs these days through our sales department.

Benefits Hard Drive Shredding

• Degaussing-this is the process of eliminating or decreasing a remnant magnetic field such as the hard disk drive of your computer and wipes the media from it so it can be safely and securely disposed..
• Physical disk destruction-this is where you render the platters severely fragmented and the disk inoperable.

If you are concerned about any sensitive data being left on your hard drive when you recycle it then the physical destruction of the disk is the best method of protection. It is also referred to as hard drive shredding and is a secure way of disposal. By doing this you are getting rid of confidential data by overwriting the deleted files. You want to make sure that the data that you have erased from your hard disk cannot be recovered anymore by anyone once you have deleted it.

When deciding to do hard drive shredding you need to be careful about the kind of software you use to complete this task. If you chose file shredding it will let you choose the file that you want removed and will only remove that particular file but nothing has been permanently removed and the file can be recovered. With hard drive shredding, or data destruction, it is the only way to remove completely any remnant data on a disk by using methods to get the remaining data and making it unrecoverable by anyone else.

Some of the benefits of using hard drive shredding includes:

• It will remove any chance of your data ever being recovered
• It will only touch your deleted files.
• It gives you increased data security because a shredded disk or hard drive cannot be patched up and made functional again.
• Helps to reduce the risk of having improperly discarded hard drives.

Hard drive shredding is the best method to use, especially for companies who are not going to re-sell or donate their old computers and just want to recycle them and keep customers sensitive information out of the wrong hands.
