Buy Cheap How to Build a Computer from Scratch Essay

Building computers from scratch offer computer users the opportunity to learn more about computer hardware and software. There are many reasons why people build their computers. Some people prefer building their computers to reduce costs while others choose this approach to customize their computers. Regardless of their reasons, building a computer from scratch is a process that starts with choosing appropriate hardware and software, then assembling all hardware together and finally installing the operating system and other programs.

First, computer users must decide on the hardware required for the computer. This calls for a selection of appropriate hard drive, processor, memory modules, disc drives, sound cards, monitors and casing. Care should be taken to ensure that the processor and memory module are compatible to the motherboard. In addition, users must choose the appropriate size of the hard drive and memory chips to prolong any future need for upgrades. After selecting the required hardware, compatible software such as operating system and application software must also be purchased at software stores. These hardware and software will be used in the next steps.

The second vital step of building a computer from scratch involves assembling all hardware components within the casing. Before assembling the components, users must wear anti-static wrist bands to avoid damaging sensitive part like the motherboard. Once this step is complete, users must first take the input-output plate and fix it at the back of the casing lying flat on a table. Next, a motherboard should then be placed on the motherboard and fastened with screws. After the motherboard is firm, users must insert the processor taking care not to damage its contact pins. After fitting, the processor on the motherboard, a fan will then be secured on the motherboards, as well. Next, the memory modules should after that be placed on the memory banks on the motherboard and locked into position. The following step will involve fastening of the hard drive and disc drive on the empty bays of the casing. Caution should be taken to ensure that the data cables connect them to the motherboard fit well. Once these components have been fixed, users should attach a cable from these drives to the motherboard. In addition, the power cable from the power supply should also be attached to the motherboard. The sound card should finally be fixed on the expansion slot. Any addition cables such as the front-panel USB cables should be attached to the motherboard. Lastly, the casing should then be closed and the power cables, keyboard and monitor attached to the casing.

The third main step involves switching the computer on and immediately inserting the system disc such as Microsoft Windows 7 discs bought beforehand. This disc will prompt the user to press any key on the keyboard. This should be done as quickly as it appears. However, should users miss it, then the computer must be restarted once again. Once the installation starts; users will choose the appropriate option, partition the hard drive as necessary and installs the operating system. Next should be the installation of software drivers and other application software such as office or media players and most powerful suitable antivirus software.

In conclusion, building a computer from scratch can be accomplished in three crucial steps. First, users must purchase all necessary hardware and software. Second, the hardware components will then be assembled systematically. Last, the users must first install the operating system followed by system drivers and other application software along with antivirus software depending on the need of the users.
