Assembling a desktop computer from scratch seems like a daunting task, especially to anyone new to computer hardware. Oftentimes, buying a PC as a set is the easier choice. What many do not know, however, is that buying the individual components and building the computer yourself are more practical. Through the latter, you have complete control over how to spend your budget and what type of system you are looking for. By doing a few research and taking some time and effort, you can get your ideal do-it-yourself (DIY) desktop computer as well as a great sense of accomplishment.
To start with, you must first identify and assemble the essential parts needed to get your computer up and running. You need to acquire the following internal components:
- Power supply unit (PSU), which provides the DC power needed by other internal components
- Motherboard, which is the central printed circuit board where other electronic components are inserted into
- Processor, also known as the central processing unit (CPU), which acts as the brain of your PC
- RAM, which stands for random access memory, where the processor stores data currently being handled
- Hard drive, which permanently saves important data even when the computer is turned off
- Optical drive, which burns and reads data from optical discs
- Graphics card, which lightens the CPU load by handling video-related processing
Besides the components encased within the computer tower or chassis, you will also need to buy the following external components:
- Monitor, which is your computer's main output to display visual data
- Keyboard, which is your main way to input data by typing
- Mouse, which controls the pointer displayed on the screen
The components found in the lists above are the most common parts of a desktop computer. Depending on your needs, you might also want to buy a printer, touch-enabled displays, and others. Confirming that each component is compatible with one another is important so as to avoid problems when you turn on your new computer for the first time.
Once all the necessary parts have been bought and assembled, you can turn on your computer and then install the important software. The operating system is the most important, because all other software can't be run without it. Depending on your need, you also need to buy a word processor, a spreadsheet program, as well as video games for the occasional leisure time. If you know where to look, many of these applications are available online and free to download. Again, just take some time and effort to accomplish this task.
If you are still hesitant to build a computer on your own, simply ask a technophile in your family to do it for you. Also try learning the know-hows yourself so that you can take care of your PC, should a problem arise and no help is nearby. The deed may seem daunting at first, but it can be eventually rewarding for you. Good luck!
