<human>:  I want to build a computer from scratch. Where should I start?
<bot>: To start building a computer from scratch, you will need to acquire the necessary components, such as a motherboard, a processor, RAM, a graphics card, a hard drive, and a case. You will then need to assemble the components and install the necessary software. A good place to begin is to research the best components that you need to buy and then look for tutorials on how to build the computer.
