This is going to be a simple guide to building a custom computer but without including every detail with wiring and such.

Step 1: Gathering Your Parts

First thing you are going to have to do is go out and get all your parts to build it. You could go out to computer places and buy each part, but they have a limited selection so going online is preferred as it is typically cheaper and gives you every possible option. The components that you will need are a CPU, motherboard, hard drive, memory, graphics card, optical drive, power supply, and case. You should do a lot of research when picking these parts because there are so many different options for each part that fit a different need.

Step 2: Installing the CPU

Once you have gathered all of your parts are ready to build, you can unpack it all and begin with your motherboard. Pretty much all the pieces that you have are going to be placed into the motherboard just like a puzzle piece. So you layout the motherboard and get your CPU and begin to install it. The CPU is just a small square piece that doesnt look like much but runs the computer. You will place it in a trap-like device on the motherboard that snaps it in and secures it.

Step 3: Giving It an Image

The next thing you want to do is install your graphics card. This is literally what gives the computer good picture and allows you to watch good videos and run high quality picture. The graphics card is fairly large compared to most of the parts and it slips in very easily into a slot on the motherboard, and then clips in on both of the sides.

Step 4: Memory

Next you will want to place your memory cards into the motherboard. The memory cards are what allows your computer to run multiple programs and operations on it at once. Basically the more memory you have, the more things you can do on your computer at the same time. These memory cards are probably the easiest to install as they also slip into a slot just like the memory card and then get snapped in on the sides as well.

Step 5: Optical Drive and Hard Drive

After putting in the memory cards, the next two components will go into the computer case instead of the motherboard. The optical drive and hard drive will go into pre-made slots in the case and the optical drive will stick out the front because it is where you put any CD's or DVD's. The hard drive is just a storage device that holds everything you save on your computer. Both of these devices will also have a wire to be attached to the motherboard in their respective plugins.

Step 6: The Final Piece

Finally, the last component you need to install is your power supply. This does exactly what you think it does. It powers everything in the computer. This is a bulky piece that needs to be selected carefully because getting a power supply too strong could fry your computer and one without enough power could short circuit it. This piece also gets placed in the case itself, but it then has wires that you will attach to all of the parts that you already put in. The only thing to make sure of when putting it in is to have the fan facing toward the bottom for ventilation.

Step 7: Putting It All Together

The final step in making your computer is placing the motherboard, with all the components attached, into the computer case. It will fit in a rectangular area on the back part of it and will then be held in with 6 simple screws. So the only tool you need to put it together is a screw driver. After putting the motherboard in you can close up the computer case and put the side panel back on and turn your computer on! Now this is only assuming you have a monitor, keyboard and mouse to actually use with it.
