<div style="text-align: justify;">by: Muhamad Fuad Have you ever wanted to buy your dream computer? You have save your monthly income to buy it but you did not know what specification you should choose since there are lot of choices in the market today. Beside budget, below are the important factors that you should look into when buying a computer. They are the operating system, processor speed, graphic card capability, power supply, hard disk, and the monitor. Take a look at this simple guide and I hope that you will have a nice computer buying experience later. Build it yourself or ask somebody else! Firstly before stepping into choosing the suitable hardware, a question that you should ask to yourself is whether do you want to build your own computer or ask somebody to build it for you? From my experience, it is better to ask somebody else to build it for you if this is the first time you want to buy your own computer. You can always learn to know about your computer hardware and software later. But, do not forget to assist the salesperson and ask him or her anything that you did not know about your computer. He might give you some tips of what should do and shouldn’t do with your computer during the building process. Choosing the hardware Now, we will look into buying hardware for your computer. Your computer hardware determines your computer speed. There are lots of factors that affect how well your computer will perform as well. The Processor Nowadays, two big companies are in the race of getting the fastest processor for mainstream are the Intel Corporation and Advanced Micro Device (AMD). What I’m going to tell you is not which one of them are the best, but some aspect of processor that you should know. The greater the processor clock your processor have, the better performance it will be. As example, a 3.0 gigahertz Intel Pentium Processor will beat the 2.0 gigahertz version of the same processor. But there are bottlenecks that limit performance in other places such as the cache’s size and latency, power consumption, and temperature. So, for conclusion it always better to choose a processor that have least power consumption, large cache size with low latency, and capable of running fast in well-accepted temperature such as 34 Celsius, and have the latest feature such as support for dual-core and 64-bit computing. Remember, don’t compare different type of processor performance with clock speed since it’s proven by AMD that clock speed did not influences the performance of the processor very much unlike the 1998 era. The Monitor Prefer choosing a LCD monitor over CRT Monitor. No heavy lifting required with a LCD monitor since they weigh less than half the average CRT monitor. LCD monitors require half the power of CRTs and emit much less electromagnetic radiation which can interfere with other electronic devices. Talking about the LCD size, 17-inch is enough already since it give the best support to resolution that operating system widely use nowadays (1024 by 786 pixels). But, if you want to keep your computer for a long time or want to use to make it as part of your Digital Media Centre, LCD Monitor with larger than 19 inch size is recommended. The Graphic Card A graphic card is a must have for modern computer today. Never intend to use integrated graphic since it will greatly slow down your computer. PC graphic such as photos and videos will require a lot of processing power. Without the help from graphic card, the CPU needs to handle all the system and graphic processing. Choosing a graphic card is easy depends with how you use your computer. If you did not run any games, graphic card without latest features is acceptable. Just make sure that the graphic card supports the incoming operating system from Microsoft, Windows Vista. Since a high-end graphic card will require high power for SLI or crossfire function, if you want to save your electric bills, consider mid-range graphic card which usually sold at 150-250 dollar. Power Supply The higher the wattage that a power supply support, the better it is. If you want to purchase additional hardware for your computer later such as USB optical mouse there won’t be a problem for you since a decent power supply will supports your need. A good power supply is the power supply that can give out as much 500 watt of power or higher than that. Hard Disk An internal hard disk with latest Sata 2.0 (serial ATA) support will serve you perfectly. Other than that, the size of the hard disk should be big since you might want to store a lot of pictures, music, and movies later. 200GB hard disk is the regular specification nowadays. If you want to keep your hard disk for a long time, 500 GB would be enough. How many hard disks should you buy? The minimum is one but I recommend you to get two hard disks for your computer. One will be for main operating system and the other one for storing your personal data. This is essential to avoid those data from clutter together. Moreover, your computer performance might increase if you use two hard disks. This is because the computer can access the operating system files directly from its own drive. The Operating System For the best user experience, operating system from Microsoft such as Windows XP still dominates the market nowadays. Since lots of people using it, getting support would not be hard. Just go to a tech support forum and your software-related computer problem will be solved there. Although you can use Linux operating system for free, it is not recommended because not all hardware supports Linux. Well, that’s all for now. Your journey to build your dream computer should not end here. Ask your friends for some advices such as a good computer hardware shop in the town or their past experiences in buying their computer. Thus, you will not feel regretted with what you’re going to buy.

How To Troubleshoot Your Computer Hardware

<div style="text-align: justify;font-family:arial;">by: Steven Stoddard There could be many reasons why you’d want to troubleshoot your computer, well, one actually and that’s because something is not working right. The process of troubleshooting is something you learn after working for a long time with computers. Often enough when there’s a problem, nothing is going to explicitly tell you what is causing the problem and how you can fix it. By taking logical steps and walking through the process of troubleshooting you should be able to solve almost any computer problem, software or hardware related. It involves identifying the problem(s), finding the cause of that problem, determining the solution, executing that solution, and testing and checking that solution to see if it solves your problem. As an example let’s say one day while using your computer the screen suddenly turns all black and you can’t see anything. We found a problem now what would be the first step to take to fix it? First check to see if the monitor is on and is receiving power, most monitors when they have power, but no connection or connection problems with the computer will display a message that says this monitor is working, but make sure you check your cables. So the next logical step to take would be to check the cable to make sure it is properly connected and secured to the VGA slot behind your computer case and to make sure the monitor cable is plugged into the monitor. Now, here’s where you have to decide what would be the next best course of action to take. you could either swap out your monitor with another monitor that you know is working to see if the problem is the monitor itself and nothing else or you can try to see if the problem is your graphics card. If your replacement monitor works, good, then you know your culprit is a bad monitor and you’ll most likely have to get a new one, because monitors are dangerous and too costly service. If the replacement monitor you used shows up a black screen as well, the next thing you’d do is check to make sure the graphics card is properly seated in the motherboard, if it is and the display is still not showing up, then swap out the graphics card to see if your problem is fixed. Generally there are only so many steps you can take before you solve the problem and everything is back in order. Make sure that before you start testing and swapping out parts that the problem wasn’t caused by you changing a software setting in Windows or some ambiguous option in the motherboard’s BIOS that causes your problem. read more about...(troubleshoot): <a href="http://computer-infocentre.blogspot.com/2008/03/how-to-troubleshoot-your-computer_1172.html" style="color: rgb(0, 0, 153);">1. motherboard</a> <a href="http://computer-infocentre.blogspot.com/2008/03/how-to-troubleshoot-your-computer_3207.html">2. power supply</a> <a href="http://computer-infocentre.blogspot.com/2008/03/how-to-troubleshoot-your-computer_1361.html" style="color: rgb(0, 0, 153);">3. memory</a> <a href="http://computer-infocentre.blogspot.com/2008/03/how-to-troubleshoot-your-computer_1056.html" style="color: rgb(0, 0, 153);">4. hard drive</a> <a href="http://computer-infocentre.blogspot.com/2008/03/how-to-troubleshoot-your-computer_9454.html" style="color: rgb(0, 0, 153);">5. monitor</a> <a href="http://computer-infocentre.blogspot.com/2008/03/how-to-troubleshoot-your-computer_6450.html" style="color: rgb(0, 0, 153);">6. graphics card</a> <a href="http://computer-infocentre.blogspot.com/2008/03/how-to-troubleshoot-your-computer_15.html" style="color: rgb(0, 0, 153);">7. soundcard</a> <a href="http://computer-infocentre.blogspot.com/2008/03/how-to-troubleshoot-your-computer.html" style="color: rgb(0, 0, 153);">8. processor</a> About The Author: Steven Stoddard Steve's Tech Guide - A blog that helps you scratch your tech itch with computer guides, informative how-tos, and important news events. <a class="hft-urls" href="http://stevestechguide.com/" style="font-style: italic;">http://stevestechguide.com</a> </div>

How To Troubleshoot Your Computer Hardware (Power Supply)

Diposting oleh Unknown Label: hardware, Power Supply, troubleshoot

by: Steven Stoddard <div style="text-align: justify;"> Power Supply If you suspect your power supply is giving you trouble, make sure you check it out fast, because power supplies can make trouble with the rest of your system as well. Irregular voltages sent from the power supply can short circuit and overheat your components thus frying them and making them unusable. Some faulty power supplies have even caught on fire, but if you’re lucky it might just smoke a little and start to smell. A few signals that your power supply is bad or is going bad would be erratic and seemingly random system behavior like system hangs and crashes, and burning smells along with smoke. If you recently upgraded your system or added new hard drives, disk drives, a graphics card or anything for that matter, be sure to check if your power supply is being overloaded with hardware. A good way to check is to use a power supply calculator. One time when I upgraded my system with a new fancy PCI Express 16x Graphics card, well it was fancy back then, I had problems with the graphics card performing while in 3d games, it was all due to my power supply being unable give it enough juice on the 12v rails so it performed poorly and didn’t act as it should have, I even swapped out the graphics card for another one believing it was bad, after checking the manufacturer’s forums it seemed like a lot of people were having problems with faulty cards, so I figured mine must have been faulty too. After getting the new card it seemed like it performed better for a little bit longer, which could’ve just been some optimizations they did to circuit board. Seeing how they sent me an upgraded version of the same card, but it wasn’t until I checked my power supply wattages that I found the real culprit. The first thing to do to diagnose your power supply is check the power supply connectors, make sure everything is plugged into the motherboard and the power cable is plugged into the power supply, you wouldn’t believe how many people forget to plug in their computer. Many power supplies also have a power switch on them so check to make sure that no one accidentally or purposefully switched it off maybe for a prank. Check the fan to see if it is spinning at the correct speed and if it’s dusty vacuum it out. Determine if the power supply cables are giving out the right amount of voltage, if you computer will let you boot you should be able to check them in the BIOS menu to see if the correct voltages are being given. Normal power supplies give +3.3 volts DC, +5 volts DC, -5 volts DC, +12 volts DC, and -12 volts DC. <a href="http://computer-infocentre.blogspot.com/2008/03/how-to-troubleshoot-your-computer_4042.html">(home)</a> </div> About The Author: Steven Stoddard Steve's Tech Guide - A blog that helps you scratch your tech itch with computer guides, informative how-tos, and important news events. <a class="hft-urls" href="http://stevestechguide.com/" style="font-style: italic;">http://stevestechguide.com</a>
