Motherboard Installation (PC Assembly) 2008-07-04 07:12:47 This is where a delicate hand will be needed.
.
When installing most computer parts, and especially the motherboard, you must remember that you shouldn't force anything in, but you can't be too timid as to not apply enough pressure to make things fit. Since all these computer parts must be universal fitting, the chances of something being just a little off here or there are expected and should no Read more:Installation

PC Assembly (Preparing the case or chassis) 2008-07-04 06:29:37 Most cases available allow access to the inside through their side panels. Some used to require you to take the entire sides and top off but since making your own custom computer is becoming more popular, the case manufacturers decided to make things easier. If your case doesn't come off in the described manner, just refer to the manual it comes with, or do some experimenting to find out how to op Read more:Assembly
Things to remember while planning in PC assembly: 2008-07-04 05:47:33 * The amount of money it takes to build a computer depends on you:
.
You can make your computer as simple or as complex as you want. It all depends on how much you want to spend, and how quickly you can learn everything. It also depends on where you buy your parts. . * Not everything will go as planned:

What fun would that be? Building a computer requires patience since the chances of gettin Read more:planning
Ports 2008-07-04 04:23:50
.
Ports - These are connectors found at the back of the computer which send and received data to and from the peripherals such as modems, monitors, printers, plotters and keyboards. Ports can be found directly on the motherboard but most are added with the use of separate expansion cards.
Serial Ports (COM Ports)
These are 25-pin male connectors which are used to connect the computer to a mou
Keyboard 2008-07-04 03:52:25 Personal taste plays a large part in choosing a keyboard. Some people like keys with a firm feel. Some prefer mushy keys. There are essentially two styles of keyboards for the XT. First is the AT layout. Second is the IBM enhanced layout. IBM received a great deal of criticism for the keyboards it used on the PC Jr PC and XT. When the AT was released they used a new layout; function keys on the le

TROUBLESHOOTING THE COMPUTER 2008-06-19 06:49:37 General Pointers:
Relax – If while troubleshooting you are going crazy truing to find the problem, do something else for a while. Leave it for the next day and get a good rest. It’s amazing how often after sleeping on the problem an answer may just pop into your head.
Work systematically – The computer parts are connected together in systematic and logical order. When you are troubleshooting
Random Access Memory 2008-06-19 06:40:38 RAM consists of computer chips, which store information. It is the form of volatile memory used to hold temporary instructions and data for manipulation while the system is running. . The term random is applied because the CPU can access or place data to and from any addressable RAM on the system. If power to the system is lost, all RAM is lost as well.
They are installed in rows called banks of n Read more:Random

Central Processing Unit (CPU) or Microprocessor 2008-06-19 05:45:01 The CPU is the first thing that comes to mind when many people think about a computer's speed and performance. The CPU is the part of a computer in which arithmetic and logical operations are performed and instructions are decoded and executed. The CPU controls the operation of the computer. Early PCs used several chips to handle the task. Some functions are still handled by support chips, which a Read more:Central

Installing the Hard Drive 2008-07-14 08:38:31 Since the hard drive is where all the information on a computer is stored it will be used quite a bit and therefore will generate a good amount of heat. That's why it's important to place it where it will get plenty of ventilation. If you look at the open case on the right, you'll notice the pictured below where all the devices will be secured. The hard drive typically goes on the bottom of this r
