To prevent this problem, the following steps have to be taken to remove static before handling any computer component like the motherboard, CPU, memory:

• Wrist should be grounded using some kind of metal strap / static control wristbands . However, these should NOT be used while working with the computer CRT monitor as the charge stored in the capacitor is very large and can cause death. If no strap is available touching a metal object periodically may remove any charge from the body.

• Push in the power button on the computer and depress it for 10 seconds with the computer unplugged before touching any computer part.
• Increase the humidity level . Low humidity levels are common in areas with air conditioning or heaters, so using humidifiers can help prevent static build up.
• Ground the static by connecting to an earthing wire or by applying a neutralizing charge
• If a carpet is being used for flooring, spray it with an anti static agent to remove the build of static. Try different kinds of shoes and soles and shoes which will pick up the least static.

One option for getting the computer components is to contact the local computer hardware shop or dealer.  If the dealer can be trusted and you have purchased parts from them earlier, you could get a good deal.  The advantage is that you can physically examine the components before purchase and it is easy to return or exchange them in case of any problem.

For online purchases, check the reputation of the website before taking  a decision.  Newegg  (www.newegg.com) is a popular online store for computer parts.  They carry a wide range of computer components,  and detailed specifications of each component are listed, so that the buyer can verify that all the components are compatible and will work properly together. The prices of the computers are competitive compared to other online stores.  Each product listed at Newegg is rated by the customer on a rating scale of 1 to 5  for the convenience of the buyer.

The customers are expected to select and the install the operating system they want. Some customers may want to install a free Linux based OS and may not be willing to pay extra. Also the current OS offered by Microsoft, Windows Vista runs very slowly on computers who do not have sufficient memory. So many customers who purchase Windows Vista have to contact the customer support and request that the software be downgraded to Windows XP Pro.

Today many manufactured computers available in the market come with free DoS installed. No CD is provided, only single page instructions that the free Dos software can be obtained from freedos.org.

To install a new Operating System (OS), the following steps have to be taken after booting the PC from the CD drive:

• first delete the existing partition using D

• Use C to create a partition

• Specify the size of 1st partition

• Then specify next partition size

8 MB will always be reserved for system partition MB

Yahoo answers - you can post your any computer or networking related question.  For a common problem, you will get an answer, but for a more complicated case, you may not get any assistance.

Press del while the computer is booting to enter the BIOS and check all the basic BIOS entries to ensure that all the settings are correct.
Depending on your system configuration, you may want to enable or disable various settings - the motherboard manual may have reccommendations for this.

If there is no problem at the BIOS level, the CPU will search for an Operating System installed on your HDD.

For a brand new HDD, if you are installing Windows XP, the following steps have to be taken

• Insert the Windows XP installation CD in the CD ROM drive and reboot.

• Press del again to enter the computer BIOS settings to set CD Rom drive as the first boot-up device.

Reboot your computer to start the Operating System (OS) install. The OS system install will take some time, and you will prompted to provide the license key.
Once Windows XP is completely installed, the other additional hardware like modems, network card, sound card can also be installed.  The drivers for these peripherals can be usually downloaded from the manufacturer website.

STEP 1:
Install your motherboard on the casing first. Put plastic stands-off under motherboard. Place in position in casing and install all screws required.

STEP 2:
Mount the CPU on the motherboard - being careful to position as required, as the fine pins are quite soft. This may take some time. Install the Cooler Fan Heat Sink assembly. Apply the paste which adds adhesion and contributes to the cooling effect on the top of CPU before clipping on the fan.

STEP 3:
Install the RAM module. To allow for easy insertion of RAM, push the white levers on both sides down. The gap in the RAM module should be matched to the slot. Push down the RAM firmly and pull the levers back up. They will click into position.

Any new motherboard should come with a diagram of the RAM layout. If there are empty slots a single ram module must be installed in the proper order.

STEP 4:
After the RAM is installed, the graphic card should be installed. It is usually next to the RAM slots and the may have to be pulled out if  the RAM was installed later .

STEP 5:
Install all the drives - the DVDRom, Floppy Disc Drive and HDD.

STEP 6:
Wiring up. Fit all your drives data cabling for the HDD, floppy disk drive (if needed) and DVDRom drive. These cables carry data signals between  hardware and the motherboard. They should be installed with their red edge facing the power supply plug.

For most motherboards, the primary slot is assigned to the HDD, the secondary slot will support an additional HDD/DVD Rom drive and the third slot will support the floppy drive.

STEP 7:
Connect up the mouse, keyboard and monitor.

LAST STEP:
As a last step, connect up all power plugs to the motherboard and drives. The main power source from the power box should be connected first.

1. CPU with Cooler Fan.
2. Compatible Motherboard
3. Ram module
4. HDD - with IDE cable
5. DVDRom Burner/Drive
6. Floppy Disc Drive - with cable
7. Graphic Card
8. Computer Casing with Power Supply box.
9. Modem
10. Sound Card
11. Network card (optional)

If you wish the Monitor, Keyboard and mouse can be salvaged from your “old” working computer system. Monitors are usually expensive and take up a lot of space, so it is better to use the old monitor. The keyboard and mouse get worn out quickly, so getting new parts is better

Hardware accessories include screws, plastic stands off ( to lift the motherboard off the enclosure), Plastic Ties.

The best custom made computers are those which are assembled by the end user or by a  reliable computer assembler who knows the applications which will be run on the computer and selects the hardware accordingly. By doing so, the user gets a computer gets the best deal at a cost effective price.

Not everyone can or even should attempt to assemble a computer themselves. Some of the minimum requirements for assembling a custom built computer  at home are as follows :

1. Intermediate to advanced knowledge of  computer hardware and assembly. You should not only be able to read and understand component specifications and assembly instructions, but also be able to fit components together and ensure that there are no loose connections.  If you are not proficient, it is advisable to hire the services of  a reliable computer technician for a few hours.  Verify the credentials of the technician if possible.

2. Tools for assembling the computer:   Magnifying glass,  small flashlight , a set of  Philips screwdrivers for assembly and needle nose pliers. An anti static wrist strap is also recommended to prevent damage to components.

Some of  the advantages of  buying / building custom built computers are :

1. You pay only for the components and hardware you need and use. Every computer user uses the computer for different applications. Most mass produced computers have some hardware features which are not used by many users. This hardware can be eliminated, reducing the overall cost of  the computer.

2. More user friendly : For a custom built computer, there is a lot of  flexibility in selecting  the cabinet , so that USB / parallel ports can be easily accessed  and peripherals like printers connected or disconnected from the computer. Though major manufacturers like HP hire some of  the “best” designers,  USB ports for many PC models cannot be accessed from the front of  the PC.

3. In case of  component failure, you are not dependent on the manufacturer and you can use a similar component  of  any other make , if the specifications match .

4. If you use your computer for gaming, the graphics card of standard computer models may not be adequate, so it is better to custom build  your computer as per your requirements.

Today, millions of computers are used all over the world in offices and homes for business and entertainment. About a decade ago  a  significant percentage of these computers were assembled, as branded computers were expensive and cost  2-3 times more than assembled computers.

However, in the last few years with increasing volumes of computers being manufactured worldwide and cost of production of the components decreasing due to improved manufacturing techniques, the cost of branded computers has become comparable to that of assembled computers.  Most consumers now prefer to purchase branded computers since the manufacturer offers an after sales warranty for a period of  at least one year (this can be extended to 3 years by purchasing a carepack) with toll free helplines.

The quality of the after sales service offered for assembled computers is often inconsistent. Due to decreasing margins, many of the  smaller dealers  use poor quality / second hand components. They may promise after sales service,  but do not respond to customer service calls. Since the volumes of the computers they assemble is low, the price they pay for each part is usually higher than what manufacturers of branded computers pay. They are also unable to carry out stringent quality control tests which larger companies incorporate in their manufacturing process.
