Putting it All Together: Installing The Processor

Now that we've learned what 
the computer components are and how they work, 
we're going to assemble our very own computer, 
a full-sized desktop. 
Computers are incredibly fundamental 
to the work of an IT support specialist. 
They're used in pretty much every aspect of the job. 
Aside from work, knowing how to build 
a computer might inspire you to try all kinds of cool stuff. 
You could custom build a gaming rig to play 
the most advanced game at the highest settings, or like me, make a home media server for all your photos and videos. Knowing how to build a computer is a skill that can be useful in lots of interesting ways. 
Before we get started, 
let's lay down some ground rules 
for this ground-up build. 
Sorry, I couldn't help myself. 
We should think about electrostatic discharge and try to 
prevent unwanted static from 
harming our very expensive components. 
Have you ever rubbed your socks on 
a carpet then accidentally zap someone? 
That's pretty harmless. But if 
you do that to your new motherboard, 
you could completely destroy it. 
How do we prevent static discharge? 
We can go about this in two ways. 
You can touch an electrical device that's 
plugged in but not powered on. 
Fyi, you should do this every couple of 
minutes when assembling a new computer. 
Another option is to wear an anti-static wristband, 
like the one I have here. Let me get it.
You connect the end of the clip to 
a non painted metal service like 
your computer and then you 
strap it on to your hands, and you're done. 
While we're on the subject of anti-static safety, 
I want to call out that when you buy computer parts, 
they'll come in anti-static bags 
to prevent accidental static electricity. 
Be sure to keep them inside the bags 
until you need to install them on your computer. 
Now, let's get making this computer. 
We'll start by laying down 
the foundation of our computer. 
The motherboard. Remember, there 
are lots of different form factors for 
motherboards and you want to make sure 
the one new purchase fits your computer case. 
We purchased a full-sized desktop case 
and have a full sized ATX motherboard. 
The motherboard, there are lots of screw holes 
which coincide with the holes in the desktop case too. 
You want to match up the holes on 
the motherboard to the holes on the desktop. 
Once you figure out which holes to use, 
screw in the standoffs. 
Standoffs are used to raise and 
attach your motherboard to the case. 
In this instance, our case has 
built-in standoffs. Let's start
by adding our components in. 
We'll start with the CPU. 
Let's take that out of our anti-static bag. 
You want to be very careful with these because 
they're very expensive and you don't want to drop them.
Once we've taken out the bag, 
let's lineup the CPU with the motherboard socket. 
Something to note is this marker right here. 
This has to align with the CPU socket on the motherboard. 
Also, don't forget to make sure you 
get compatible CPUs that fit your motherboard. 
We have the LGA CPU in 
the LGA compatible motherboard socket. 
Let's go ahead and align the correct orientation of 
the CPU and secure it in place like this.
Like I mentioned before, 
you want to make sure that the pointers on 
the CPU and the socket are aligned. 
The easy part is putting a CPU in, 
the fun part is securing this. 
Just note that when you secure the CPU in the socket, 
you do need to use a bit of 
force so it's tightly secured in.
Perfect. Now the CPU is secured in the socket. 
Now that our CPU is in place, 
we need to add our heat sink on top of it. 
The heat sink is used to dissipate heat from our CPU. 
I'll show you some cool things. 
This part right here, 
this is what our CPU relies on to stay cool. 
It takes the heat from there and then 
uses this fan to blow it out. 
Before we attach the heat sink, 
we need to apply an even amount of thermal paste. 
Let me get that. This is the thermal paste. 
Thermal paste is used to better 
connect our CPU and heat sink, 
so the heat transfers from one to the other better. 
To get started, apply a dab 
of thermal paste and spread it evenly with a flat object. 
Let's do that on our CPU right here. 
The first thing that you want to do is 
slowly apply a slat dab on the CPU, like so.
Then with a flat object apply the thermal paste 
evenly throughout your CPU to go halfway right here, 
halfway right here, halfway right here, 
and then halfway right here.
Just make sure that it spread evenly throughout the CPU. 
You may have to do this multiple 
times to get this correct.
Once you have that in place, 
you're going to take your heat sink and 
then you're going to press it against the CPU. 
Something to note is these screws right here. 
They align with the CPU socket so they can 
guide you while you put the heat sink on.
Great. Once you have all four sockets aligned, 
go ahead and get your screwdriver 
and then tighten down the sockets.
One thing to do is to make 
sure that you screw opposite sides 
first so you know that 
the heat sink is attached securely.
One thing I like to do again is just to go over 
my screws to make sure everything is tightened securely.
Great. Now that our screws are 
tightly on and our heat sink is secured to the CPU, 
you have to plug this power cable to the motherboard. 
This is important because this is what controls 
the fan speed via the motherboard. 
Perfect. Now you've fully 
installed and connected your CPU to the motherboard.
