How To Choose A Computer Case

window — Sun, 12 Oct 2008 01:00:29 +0000

Things to Consider When Choosing a Computer Case

1. Form Factor
There are different sizes of motherboards, which in turn require different cases to house them. Case form factors share the names of the motherboards they support, and some of the common ones include ATX, Micro ATX (mATX), FlexATX and Mini ITX. ATX motherboards are perhaps the most common, and the largest of the four, measuring at most 12″ x 9.6″ (305mm x 244mm). A Micro ATX board is at most 9.6″ x 9.6″ (244mm x 244mm), a FlexATX is 9.0″ x 7.5″ (229mm x 191mm) and a Mini ITX comes in at a tiny 6.7″ x 6.7″ (170mm x 170mm). ATX and mATX are by far the most popular motherboard sizes for consumer motherboards, and hence, most cases are made to support one or both of these sizes.

2. Size
Size may go along with form factor in many respects, but even while considering cases of the same form factor, there can be variations in size in a few respects. Areas where size can vary are in overall dimensions, the number of exposed 5.25″ and 3.5″ bays, and the number of internal bays.
Internal bays are generally reserved for hard drives, and systems with multiple drives require the necessary space. So, if a user decided he really wanted a yellow colored case, but needed room for five hard drives, he would be forced to choose this one (5 internal drive bays) over this one (4 internal drive bays).

3. Cooling
Cooling is a critical feature to consider when selecting a computer case. High end systems can generate a good deal of heat, and the case needs to be adequately cooled to keep the system running and stable.
The basic configuration for case cooling involves having one intake fan on the lower portion of the front surface, and one exhaust fan higher up on the rear surface. This allows cooler air to be drawn in, passed over the various heat generating components, and exhausted out the back. There are many other cooling configurations available that may provide improvements in terms of cooling performance and noise. Another approach to better cooling is to throw more fans at the heat. This Matrix case adds another fan to the side panel which will draw cool air in right on top of the processor and video card, two of the hotter items in a system. Other cases will add an exhaust fan to the top of the case, which pushes the heat out just like a chimney.

4. Installation Features
Installing a system into a case can be a time consuming affair, which can become annoying to those who find themselves in a continuous cycle of upgrading. Many cases now include convenient features to make installation much simpler, and far less time consuming. Some of these convenient installation features include a removable motherboard tray, removable drive cages, tool-less expansion card mounts, tool-less side panels, and tool-less drive rail systems. Being able to remove the motherboard tray and drive cage makes it easier to work on those specific areas in the open, and having a tool-less system for mounting drives or cards means there is no need for screws or a screw driver. Definitely time savers!

5. Convenience Items
It is not enough for a case to house a computer system any more, it now needs to multi-task. Having regularly used connections on the front or top of the case is one common convenience feature that many people look for. Cases such as this A-Top Z-Alien model let users forget about the annoyance of reaching around the back of their case to plug things in, as USB, Firewire, headphone and microphone jacks are located on the top.

6. Style
A few years ago cases only came in one color and one basic style plain beige boxes. If you’re nostalgic for the olden days of computer cases, Computer Geeks still has one for sale in this style, the KG-200. But cases now come in styles from mild to wild, and in a whole rainbow of colors. Some have large windows in the side panel to show off the case’s insides, some include special lighting effects, and some have appearances that might scare the kids. At this point there seems to be few limits in case design, but there are always classically styled cases in updated color schemes for those who want something modern looking, but nothing too intense.

7. Power Supply
Many cases are sold with a power supply included, but this power supply might not be the correct one for the system to be installed inside of it. An adequate power supply needs to be chosen to meet the demands of the system, and this may very well mean buying an additional power supply to replace the one included, or selecting a different case with a more appropriately sized power supply.

The Generation-X Computer Monitors

window — Sat, 11 Oct 2008 01:00:57 +0000

A computer is incomplete without its output device. Any work cannot be accomplished without this device. PC monitors are called visual display device units, which are simply known as monitors. There are generally five types of monitor available in the market. These are,- Cathode ray tube, passive liquid crystal display, TFT monitor, Plasma monitor and Penetron monitor.
The performance of a monitor can be measured by some factors like response time, refresh rate, display resolution, power consumption, contrast ratio and luminance. Modern computer displays can show thousands or millions of different colors in RGB color space signals in continually variable intensities. While many monitors have the analog signal relay, some more recent models (mostly LCD) screens come with digital input signals. It is a common misconception that all computer monitors out there in the market use the digital technology. The traditional home computers were using a composite signal output to drive the CRT monitor. Those were known as TTLs, which used to result in degraded resolution. Later, the digital monitors come with the support of LVDS, or TMDS protocols. For displaying the computer generated output, several different technologies are used like the liquid crystal display technology, video projector technology, organic light-emitting diode display, penetron technology and cathode ray tube technology. From all these technology, generally LCD technology, CRT technology and plasma technology are used.
Some users use multiple monitors. Then there are some monitors which can be operate in multiple modes. PC monitors also have some additional features like touch screen, directional screen and super power saver. Touching is the input method of Touch screen monitors. Items can be selected or moved by the help of a finger, and finger gestures convey commands. This does however mean the screen needs frequent cleaning due to image from fingerprints. Narrow viewing angle screens are used in some security applications.
Major computer monitor manufacturing companies are – Acer, BenQ, Hewlet-Packard, LG Electronics, Viewsonic, Philips, Samsung and Sony.
Most modern pc monitors come with a power saver system which is switched on if no video input signal is received. Modern operating systems can thus manage the power of a monitor after a specified period of inactivity. This also extends the service life of a monitor. Most modern laptops provide a method which gradually dimming the screen after periods of inactivity.

Computer Monitor Buying Information

window — Sat, 11 Oct 2008 01:00:03 +0000

You can have the best computer in the world, but without a monitor you can’t even use it! A lot of times people can get so caught up trying to find the right computer, they forget all about the monitor that goes with it. The fact is, when using your computer; the monitor is what you’ll be looking at all the time. If you have a great computer but a poor monitor, it may be time for an upgrade. The question is what do you look for in a computer monitor?
Below, you’ll find a few things that our product specialists recommend our customers to look for when shopping for a computer monitor.
Screen Size: When buying a monitor, it’s important that you get a screen that is big enough for you to be able to see details with ease. We recommend monitors 17 inches and up, but having one slightly smaller can still work for you.
Screen Type: Generally you have two types of screens that you can choose from, CRT (Cathode Ray Tube) and LCD (Liquid Crystal Display). CRT’s have traditionally given better color quality and response times, but as technology has advanced there are many LCD’s that can compete. The advantages of an LCD (flat panel) monitor are that it almost always takes up less desk space and is more energy efficient than a comparable CRT monitor.
Response Time: With the older LCD models, or the base LCD models, you’ll often see slow response times. The response time is how fast the pixels within the monitor turn on and off. With slower response times, you can see trails left behind of fast moving objects when watching a movie or playing a video game. We recommend getting an LCD monitor that has a response time of less than 16 ms (milliseconds). The faster the response time (the lower the number), the better results you will get as far as response time goes.
Inputs: Most monitors come with a single standard VGA style connection, but some can come with many more options. These include inputs for S-Video, Composite, Component, and even HDMI. The most important thing to consider is whether or not your computers video card will be compatible with at least one of these inputs.
Format: Most monitors come in either the 4:3 (Standard) format or the 16:9 (Widescreen) format. If you don’t have a particular preference for either one, you should go with the 16:9 as this is the format used for HDTV, and it allows you to view more on the screen at once. We recommend the 16:9 formats because if you upgrade your computer in the future (which might have a HD or Blu-Ray DVD Player), you won’t have to upgrade your monitor as well. This will prolong the time you use your monitor and you’ll get more from your investment.
Extra Features: You might want to consider a monitor that has more capabilities than just the standard features. Some of today’s monitors come with USB hubs, memory card readers, and even built-in speakers. If you want to save desktop space this can be a good option for you, but note that the cost associated with these extra features will be higher.

Flat Panel Monitor of Your Choice

window — Fri, 10 Oct 2008 01:00:58 +0000

If you are still not on the flat-panel monitor bandwagon, you have got to be considering doing it soon. And, if not, then you should! It’s the trendiest peripheral to own. It represents power, fashion and all things young and happening. Until you replace your CRT screen you wouldn’t notice how much you detested that monstrosity! But before you spend your hard earned money, getting to know the object of desire will do you wonders.

Buying guidelines:
1. Flat panel monitors use interfaces - analog or digital. The most up-to-date models have digital interface but an all-digital configuration costs a good deal more. If you are purchasing an analog flat panel, you should attach it with a digital interface to your video card with a digital out jack to mainstream the signal.
If you are thinking about to buy a digital interface, you need to investigate its compatibility. There are several digital interface standards available today-Plug and Display (P&D) from the Video Electronics Standards Association (VESA), Digital Flat Panel (DFP) from the Digital Flat Panel Working Group, and Digital Video Interface (DVI) from the Digital Display Working Group (DDWG).
The P&D interface is the oldest of the three criteria and chances are your new model wont have this convention. Support for DFP standard is seen across many hardware vendors. The DVI standard is the newer and the most popular. Do your research and whichever standard you chose, you need to match its ingredients that consist of cables and video cards!
1. Pixel-refresh response time: In a LCD monitor, the time required to switch from light to dark objects or vice versa, is referred to as Pixel-refresh response time. If the response time is poor (more than 40ms), you may see ghosting effect, i.e., the image seems to remain longer on the screen than it actually is!
Whereas in a text environment this would hardly matter, in a gaming or media centric environment the effect could be a deterrent. More inexpensive models give more ghosting than their costly counterparts. Also, pixel-refresh response time is not articulated on the monitors. You need to watch in detail to judge the performance of each model.
1. Viewing angle: One trouble with a flat panel monitor is its viewing angle. Laptop users must have experienced this problem. Moving away from the monitor in any direction causes the display to appear black! Various models offer different viewing angles horizontally and vertically.
Find the one better suited to your discretionary income! In any case, for a home PC, the viewing angle doesn’t make much difference but if the monitor is going to be used for official presentations then it should have viewing angle of at least 120 degrees horizontal and 100 degrees vertical. Also, ask for add-ons like pivoting frames.
1. Size: bigger is better, but with flat panel, remember 15-inch screen gives you the experience of a 17-inch CRT monitor. If you can shell out for 17-inch flat panel, by all means, go for it, if not, a 15-inch screen should not be a disappointment.
Other things to check when buying a flat panel are guarantees and warranties. A three-year warranty is recommended. People change the monitor settings in stores and while purchasing; make sure that you analyze the piece adequately. You now have the basic information; all you need is time to check out the market!

Monitor Color Problem

window — Fri, 10 Oct 2008 01:00:06 +0000

If you think that electronic repair is very difficult to learn then you have to read this article where only by using a solder gun could solve a Monitor color problem. Of course there were many tough dog cases (very difficult to find out the fault) in electronic repair but at the same time there were also many cases that can be solve by some simple ways. This LG 710E LG Monitor came in with no blue color problem. How do I know if the blue color was missing? Simply run a color test (that you may also download from the internet) or from a Monitor testing program generator, you could clearly see as which of the color is missing when you run the color bar test.
A missing blue color in the Monitor could cause the display to turn yellowish. Troubleshooting color problem is one of the easiest in Monitor repairing. Whether the missing color is from blue, red or green there are some areas that you need to check in order to successfully repair it. Here are some of the points that you need to check:
- A bended color pin at the VGA connector. (If pin one is bend then there would be no red color)
- A defective VGA signal cable. If the internal wires were broken then there would be missing colors. You can check if the signal cable is good or bad by doing a continuity test using a millimeter.
- Dry joints in the CRT board such as in the CRT socket pins, video pre amp and driver IC and even at the connector pins. In fact this problem contributed about 80% of Monitor color problems. Applying fresh solder would usually solve the color problem.
- A defective IC either in the Video Pre-amp or Video Driver IC.
- Faulty components in the CRT board. It could be a shorted driver transistor or even electrolytic capacitors that the ESR reading had shot up!
- A bad CRT socket. Sometimes decayed glue could cause the internal pins rusted and thus affecting the colors. Replacing only the CRT socket would definitely solve the problem.
- A weak or a defective picture tube (CRT tube). Yes, I do came across one of the electron gun (most probably the cathode materials had used up) in the tube faulty caused a missing color in the screen. There’s no way to repair this type of problem-the only way is to replace the CRT tube.
- In the newer type of Monitor, color setting is saving in the EEPROM IC. Thus, if the EEprom data is corrupted, you would also get a missing color! The only way to repair it is to reprogram the IC or use a soft jig to tune it back the color setting.
Now, which one of the above is the easiest to start with first when comes to troubleshooting the color problem? I believe you would agree with me that the first, second and the third are the easiest compare to the rest. Normally I would hit the Monitor with my bare hands to see if there are any changes in color at the display (be careful not to hit too hard till the casing broken). If there is a change or flashes then I can say that the Monitor has dry joints. And if it stills the same no matter how many times I hit it, I will then starts check the VGA connector and the cable.
In the above Monitor, the problem was dry joints because when I softly hit it with my hand at the side of the Monitor, the blue color immediately appears. The aluminum shielding at the CRT board was opened and I could clearly see lots of dry joints especially in the video pre amplifier and the video driver IC. When you resolved please don’t just touch on the IC’s only, you need to resolved others area as well like the CRT socket pins. Doing this would prevent any color loss again in the future. A good job would prevent call back and to save you time and money and most of all your reputation!
After everything was done, you then need to gently knock at the CRT board again with the plastic handle of the screw driver to see if the color problem still exists. You may also knock on the main board just in case there is any dry joint there. One more thing, if you find that the Monitor is a bit dusty, you may use a vacuum cleaner and a brush to clean up the dirty area. Whether you are repairing the LG 710E or any other brand of Monitors, if you come across any monitor color problem, you can always use the procedure above to find out the fault. If the VGA signal cable is okay and there were no dry joints in the Monitor, I guess the only way is to use voltage testing method and start checking components with your tester or meter.

Pleasant Experience With A Flat Panel Monitor

window — Thu, 09 Oct 2008 01:00:29 +0000

A flat panel monitor is really not essential for most computer applications, because, well frankly, any old monitor will do. All your really need from your computer monitor is the resolution to word process, honestly, unless you are some kind of super gamer, or perhaps an artist or graphics engineer. However, a flat panel monitor can be nice and make your computering experience more pleasant by far. First of all, it takes up much less power than a normal monitor, (also known as a crt monitor) so a flat panel monitor can greatly improve your computering experience by decreasing your electric power consumption.
Second of all, there is a subtle distortion provided by normal crt monitors which you don’t get with flat panel monitors. Your normal old standby crt monitor has a curved screen, and although your mind has been carefully trained to edit it out through hours and hours of fixedly staring at the computer screen, nonetheless, it does cause eyestrain which can be avoided with a flat panel monitor. You won’t really understand the difference until you try a flat panel monitor, so I suggest just trying it - your eyes will thank you, and then you will have to track me down and thank me. A flat panel monitor just has a clearer image, and that is that. It doesn’t distort, and besides that, the colors are more even and there isn’t the flicker of a normal monitor. You are trained to edit out the flicker too, but believe me. It is there, and you will notice the absence of it when looking at your beautiful new monitor.
Also, since so many people look at movies on their computer, if you are one of them, (and I know I am), it absolutely makes sense to buy a flat panel monitor. It just makes the image prettier, and the experience more enjoyable. Especially with the lights out, any distortion can cause vertigo and discomfort, so for your own viewing enjoyment, how can you go without a flat panel monitor. Another reason for a flat panel monitor, although probably not the biggest reason for most of us, is that it saves space. It lacks the size of a normal monitor - not only the screen, but also the body of a flat panel monitor is flat. This means you can fit it in a smaller space, or can have more room on your desk for other things such as books or amusing office executive toys such as wheels that spin up and down ramps indefinitely.

19 Inch LG Flat Screen Monitor

window — Wed, 08 Oct 2008 01:00:59 +0000

If you’re in the market for another monitor, you really need to consider a flat screen. These cool devices take up a whole lot less desk space and actually are a whole lot nicer to look at as well. Those old boxy monitors are a thing of the past. Not only do the flat screen monitors take up less space, but they’re actually not as expensive as they used to be. You can easily get one for $200 or less. That price is amazing considering what they used to be just a couple years back. Flat screen monitors are now within the reach of everyone!
This is one sleek looking LCD wide-screen monitor. LG has really put out an excellent product. One customer has said it is the best they have had. It even offers more clarity and brightness then an HDTV.
To cover the basics this monitor is certified for Windows Vista and the monitors design is intended to compliment the new OS. This monitor offers a 1440 x 900 screen resolution along with 16:10 aspect ratio designed to offer you a better view of the screen. For those that do not know what aspect ratio is–it is just the width of the screen divided by the height.
One of LG’s personal technologies is the FLATRON F-ENGINE. What is that you ask? Well, it is a picture enhancing computer chip that delivers you with amazing color, superb contract and image quality. This is what makes the monitor so good. The FLATRON F-ENGINE is able to balance the contrast and brightness both independently as needed to again keep the image supper for you. When it comes to response time for the monitor you have been used to times like 25 ms or maybe 16ms. That is milliseconds but the higher the number the less crisp and clear your picture. Now LG has really set a new level of excellence here by providing you with a 2ms response time. This delivers you a very crisp and clear picture or image.
Another way that this screen provides you with excellent qualities is by offering you with a 170 degree viewing angle. This means that even at up to 170 degrees from the center of the screen you can see it very well. This means that when you are showing someone something on your monitor they do not have to sit right next to you in order to see the screen. You can both have a little breathing room while viewing the screen clearly. How much room with this great monitor take up? With the stand the monitor measures 20.1 inches x 16.7 inches x 6 inches. That sure is a lot smaller then those old box monitors that weighted a ton. Speaking of weight, this LG monitor weight in at just 7.9 pounds–much better then the old days.
Of course the box will include the monitor and the all the basic cords to connect to power and the computer. In addition the monitor comes with a 3 year warranty that covers labor.
This monitor will give you exceptional value for your money and deliver you great graphics. You can find these monitors from $230 or less depending where you shop.

Benefits of Flat Panel Computer Monitors

window — Wed, 08 Oct 2008 01:00:39 +0000

Flat panel computer monitors are all the rage these days. We live in an overcrowded world and anything that saves space is a great thing. In fact, many of the newer computer desks are set up to take these monitors into consideration. It won’t be long before the flat panel computer monitors are the standard.
In the meantime, those of us with the clunky old huge monitors can look at those with the sleeker slimmer flat panel computer monitors with envy. If you haven’t seen one you should really check them out. They come in many sizes and with many different price ranges. Depending on what you use your computer for, you may find that you can do quite well with one of the lower end flat panel computer monitors. If you use a lot of high-end graphics intensive functions on your computer you will want one of the better quality (and more expensive flat panel computer monitors). These flat panel monitors not only save space, but they are much more environmentally friendly. Less parts to get rid of once they need replacing, this means they take up less space in landfills. They consume less energy and they have fewer emissions than traditional CRT monitors. These small favors add up when you consider how many households worldwide own computers.
Not only are these monitors more environmentally friendly, they are also work place friendly. They are easier on the eyes of workers and free up desk space to allow for more productivity in smaller spaces. With larger companies paying a premium for office space every little thing that results in needing less space is a good thing for overhead expenses, not to mention anything that can increase productivity.
Flat panel computer monitors offer many benefits to the average consumer. Check them out and see if one of these might be well on its way to your wish list.
