Here's a general checklist for building a PC:
1. Determine your budget and purpose for building the PC.
2. Choose a CPU and motherboard that are compatible with each other, and select the appropriate chipset and socket type.
3. Select the appropriate amount and type of RAM for your system.
4. Choose a power supply unit (PSU) that can provide enough power for all the components in your system.
5. Select a case that is compatible with your motherboard and provides enough space for your components.
6. Choose a graphics card if you plan to do gaming or other graphically intensive tasks.
7. Select a storage option, such as a solid-state drive (SSD) or hard disk drive (HDD).
8. Choose any additional peripherals, such as a keyboard, mouse, and monitor.
