tell me how to build a gaming pc​

Answer 1

It's better to buy a gaming PC....

Answer 2

Well building a gaming PC isn't really that hard but it can be expensive, given the games that you want to play. By far the most popular category . Capable of playing most new games with good enough graphics and FPS . Around 800–900€ for the tower and you get very good performance out of them.

• Workspace. You will need a large surface to work on, such as a table. To prevent an accidental electrostatic discharge (which can damage sensitive components), make sure you stand on an uncarpeted surface.

• Screwdrivers. You will need a Phillips #2 screwdriver for just about everything. If you're installing an M.2 device, you'll also need a Phillips #0 screwdriver.

• Before you start picking out components, you should have a case — or, at least, a case size — in mind.
• The main thing to keep in mind when picking a case is where you're going to put the computer. Your PC's final location will dictate how big you can (or cannot) go, and it will also help determine whether various premium case features are worth splurging on. You probably don't want to pay for a tempered glass side panel if the computer will be hidden under your desk, for example.
• Cases typically come in three sizes: Full-tower, mid-tower, and mini-tower. These are very general categories (case sizes are not standardized among manufacturers), but they're based on motherboard size.
• Now it's time to get your components together. This step can be as hands-on or as hands-off as you like; you can thoroughly research each individual component on your own and create a custom build from scratch, or you can find a pre-made build online and adjust it to suit your specific budget and needs.
• We definitely recommend coming up with a budget before you start picking components (it's easy for component shopping to get out of hand). Remember, you can always upgrade individual components later.
• In addition to your case, here are the components you need to build a gaming PC:
•    Central processing unit (CPU)
•    Motherboard
•    Memory (RAM)
•    Graphics processing unit (GPU)
•    Storage
•    Power supply unit (PSU)
•    System cooling
•    System cooling
•    Gaming peripherals

•    Operating system(OS)

STEP 1: INSTALL CPU

Parts/tools: Motherboard, CPU

Take the motherboard out of its antistatic packaging and put it on your work surface. Find the CPU socket, which will be covered with a protective plastic cap. In one corner of the plastic cap, or more commonly, on the socket itself, you'll see a small arrow — take note of where this arrow is.

• Next to the CPU socket, you'll see a small metal lever. Press down on the lever and pull it gently to the side (away from the socket) to open the socket tray.

• Open the CPU and remove it from its packaging. Be very careful when handling the CPU — both the CPU and the CPU socket are extremely susceptible to physical damage. Hold the CPU on the edges — never touch the pins on the bottom of the chip, because your fingers can add dust or oil, and try not to touch the top of the chip either.

• In one corner of the CPU, you'll see an arrow. Line this arrow up with the arrow on the socket, and gently place the CPU onto the socket. Once the CPU has been gently seated, you can lower the retention lever down and push it back into place. Lowering the lever may require some force, but seating the CPU will not!

STEP 3: INSTALL CPU COOLING

Parts/tools: Motherboard with installed CPU, CPU cooler, thermal paste, CPU cooler manual

• There are different types of CPU coolers. For exact installation instructions, we recommend you consult the manual that came with your CPU cooler.

• Some coolers require a mounting bracket. The motherboard may have a bracket pre-installed; you may need to remove this bracket if your cooler doesn't need a bracket, or replace this bracket if your cooler uses a different bracket. Do this before putting the motherboard inside the case.

• Some coolers come with thermal paste pre-applied to the conductive material (which sits on the CPU) and some coolers do not. If your cooler does not have pre-applied thermal paste, you will need to manually apply thermal paste before you seat the cooler. To apply thermal paste, squeeze a small dot (no larger than a grain of rice) onto the middle of the CPU. Then, place the cooler on the CPU — the pressure will spread the thermal paste adequately.

STEP 4: INSTALL MEMORY (RAM)

• Parts/tools: Motherboard, RAM, motherboard user manual
• Determine how many RAM slots your motherboard has (most have either two or four). If you're going to fill all available RAM slots, simply snap the RAM into place. If you're not going to fill all of the RAM slots, consult the user manual to find the correct configuration and populate the RAM slots accordingly.

There r more steps but sorry I can't continue or else it won't get posted as it exceeds 5000 characters.
