Transcripts

this is a standard PC uh no markings uh

you can buy this at any store any

Computer Outlet

um to get into the computer you look at

the back make sure that all your

connectors when you lay the computer

down all the connectors are on the

bottom um these are thumb

screws you unscrew them

put them off to the side and you slide

back and then lift up just takes the

case

off now this is the inside of a

computer you have a power

supply these connectors come off the

power supply Supply power to everything

on the system board and on the

components this is a processor fan heat

sink which is over the microprocessor

processor there's several components

that are on here that we'll talk about

later you have your hard drive you have

your CD

ROM and this is this component down here

is called your

motherboard we're going to take this

apart the blue cables that you see here

are called SATA cables sat a SATA cables

there's a pin on the top of one of these

you squeeze and pull see this pin here

what you do is you squeeze that pin down

and you pull out and it comes off of the

hard drive and I'm going to take the

power which has the same type of

connector only just a little bit longer

we going to do the same thing up top

squeeze and

pull same thing with the power squeeze

and pull the power is supplied through

the power supply the S cable is supplied

through the system

board this these cables here these SATA

cables are connected to SATA ports that

are on the system board

again you squeeze and you

pull set these off to the side as

well we're going to start disconnecting

power to everything this power cord

right here connects to a case

fan they simply just

unplug this power connector connect

conect all the power to the system

board

squeeze and pull directly out it's got

this little clip it Clips onto the side

of the system

board again another case fan unplugged

power and you have a four-prong power

connector down

here supplies more power to the

board it also has a little squeeze pin

and it pulls right out

now your power supply is completely

disconnected from your system

board now we're going to remove the

power

supply okay to remove the power supply

there are four screws on the back

side get a Philip

screwdriver make sure you don't lose

your

screws

[Applause]

once you finish taking out all four

screws power supply should just fall

slide forward tilt back towards the

board lift straight

out that is a removal of a power supply

now let's remove the hard

drive normally there are two screws hold

power supply in on either side top and

bottom let's remove the hard drive

screws and remove the hard

drive slides

forward and your hard drive has been

removed if you have screws on the on the

other side on the opposite side stand

the computer back up

remove the screws on the on what we call

the bottom side remove your thumb screws

Slide the tray open up that portion of

your computer these two screws will

release the CD ROM

drive turn it back

around

two screws on this

side once you've removed the screws from

the CD ROM push from the back out

forward and your CD ROM slides forward

now to remove the system board you can

first have to remove each one of the

components that are tied to it cables

PCI connectors or P PCI Express whatever

external cards or what they call add-on

cards you'd have to remove those this is

considered memory doesn't necessarily

have to be removed when you're Mo

removing the motherboard but you can to

remove the memory there's a tab on

either side you pull the tab out pull

this tab on the other side

out and the memory

slides right out there's your memory

stick now we're going to remove this PCI

card to do that you'll see the screws

inside here it's hard to get to there's

a cover on the back side that we have to

remove first this is not normal on on

all comp on all computers some of the uh

the big box computers do not have these

most custom cases

will remove your case it exposes all

your

screws you find which one has the the

silver tab that usually indicates a an

add-on card unscrew it

go back into the

case grab both corners and pull straight

out this will take your card your PCI

card off of the system

board now most of the cables that you

see here come from the front

panel the front panel has a card reader

it's got USB ports audio headphone jack

it's got a power button a power LED or

power light and it's got indicators for

your hard drive and another lights on

the

front so what we want to do is

disconnect those cables from your system

board real simply don't you don't don't

pull too hard just grab firmly and ease

them out just pull lightly and they'll

all unplug and notice how they fan

apart this is your USB cables do the

same thing

grab lightly and

pull these do not fan apart and it has

the word USB or has the the uh letters

USB on them this will tell you these are

for the USB ports and the card reader

for up front then this cable again pull

from here it tells you that it's an

audio port came from

here and it'll tell you on the system

board where it says

audio now let's let's remove the

motherboard to remove

the the system board there's there

screws that hold it on these screws are

are

indicated by little

circles throughout the system board and

that holds it in place so it won't it

can't move and once we remove those

screws the system board should slide

towards the front of the case and pull

straight out

okay I'm using a lightly mag magnetic

tipped screwdriver to kind of help some

people don't uh don't necessarily think

it should be used and if that's the case

if you don't feel comfortable with that

then then don't use them I'm sure

whenever you're putting these screws

back in that you don't uh you don't

overtighten them they just need to be

tightened up enough to where it it holds

steady motherboard should lift straight

up now that you have your system board

out you can replace your processor this

is the easiest thing way to do it I like

to put the the processor and the heat

sink on before I set your set my

motherboard back in my box or or replace

it the reason being is it allowed me one

to handle the the device a little easier

and two I'm not confined in space so

what I want to do is on on every heat

sink you're going to find a fan that fan

usually has a power cordin it's usually

plugged

in to a power connector and it'll tell

you on the on the Sy boards where a CPU

fan should be plugged into this is on an

anti-static bag so that you don't uh you

don't any static electricity to the

system board unplug your power

again it you don't have to yank on them

just slightly pull them out um there's a

screw inside of each one of these that

you can remove the fan some people

remove the fan or you can just remove it

by this take that lever and you lift it

up get you a flathead

screwdriver push

down and it releases it on this

side once it releases from this

side you

can release it from that side and your

whole

processor should lift right off of

there now this processor is mounted it's

not mounted but it's stuck to the heat

sink because of the heat sink paste take

your screwdriver and lightly turn

it and that should break it loose and

that is your

processor this is the arm that it comes

off of locks it into place on each

processor you have a row of pins they

have a pattern inside you'll notice that

there's four holes missing there's also

four holes on the system board itself on

the processor socket when you match up

your triangles you set it back down into

place that pattern will match up you

don't want to force it it should drop

right into place if you match up your

triangles you lock it back

down and you're

finished so let's talk about the

components on the system board um this

is your power main power from your power

supply this is a IDE connector for the

older IDE hard drives or or CD ROM

this is a floppy Drive connector just in

case you have a floppy Drive which they

don't really make hardly anymore these

are SATA connectors SATA stands for

Serial ATA if you'll notice inside they

they're very distinctive uh your SATA

zero is your highest port it's your main

Port where your where your uh hard drive

would plug to and then you have your

SATA one two three on the other side for

any others you have PCI slots you have a

video port

uh the only thing that fits in this port

would be a video card PCI Express video

card you also have a PCI Express 2 uh

which is another video card these

pinouts up here uh is where you would

plug your front panel uh for your power

switch and your your front speaker the

LED lights this is your USB port you'll

notice what it says up here these are

both your USB connectors for the front

this is a Communications port in case

you have a uh Communications card in the

front you also have on the back you have

audio ports which is your your speaker

microphone your headphone Jacks you have

an Ethernet connector for your network

you have two USB ports here uh four more

on this side you have a DVI port you

have an a VGA port both of these are

video you have if you notice this one's

green and purple this this is a PS2 Port

you can plug either a mouse or a

keyboard and then you have two more USB

ports on the front side your memory

socket sockets you have two uh DDR

memory sockets right here this processor

is an AMD processor you can tell cuz it

says am3 or am2 plus this is your

processor socket these are the mounts

your heat sink this is your gigabyte

motherboard this is a

chipset uh heat sink it keeps your your

CH chipset cold uh are cool um then you

have variety of capacitors and um and

resists and different little chips on

the board that will help you this is

called a Coss

battery you have your audio

port uh that's basic the basic

components of a system board and and all

system boards uh are different some of

them won't have a floppy um uh um Port

some some of them will not have an IDE

port anymore everything's going to sated

drives you may not have a PCI I mean a

PCI Express connector anymore you may

just have the PCI

2 uh you may not even have any PCI

connectors this is your four port power

connector uh which which supplies power

to the processor and all the ports in

the back here uh this power connector

supplies ports to power to everything

else and that's basically the components

you have uh you have fans to plug in

here on either side this is right here

for spit if is is um surround sound IO

right here another audio port and that

should that's your basic

components now that we have everything

apart we're going to put everything back

together we have our processor back in

and it's locked down um the good thing

to remember is the paste that you see on

here anytime you're putting it putting a

a processor back on you want to add uh

some type of thermal paste back on

between the processor and the and the

heat sink itself to kind of keep that

that section cool so what we're going to

do is we're going to turn this all the

way back around just like we had it and

we're going to set it back in

place we're going to turn it and we're

going to make sure that it's locked down

on this side

here so when we turn it back the other

side this portion we have to push down

on just a little bit where it locks into

place now that we've got this pushed

down on both sides we're going to lock

the lever in

place and that keeps this from

moving now we take our power connector

four port power connector it's got the

little slide so it tells you which way

it's supposed to go and it slides all

the way down to the bottom till you hear

it

connect now that we have this in place

we can add our memory

back as well the memory can go in on the

outside just as just as easy as it can

on the inside so they want to line up

the grooves with the grooves that are in

the in the system boards

themselves so you want to make sure that

the grooves match up before you insert

it want to make sure our Tabs are

open on both sides there's a rail that

it goes

into here and

here and then you want to push down on

both sides firmly until you hear it

click if you have two you can put it on

either one of them if you have an

additional memory you can add that to it

as well this just has a single stick of

memory in it and we'll get into that

further in another video what's what

type of memory and what type of slot so

now we're ready to put this back into

the system board and right back into the

uh into the computer so we take our case

like we had before it's empty and we

want to add the system board back in so

we're going to lay it back down we're

going to put the motherboard the the

motherboard back in notice on the

back how you got your

holes aligned where each one of the

components go and it tells you where the

keyboard or Mouse and it tells you all

the other things and we want to align

the back of

these with the ports that are on the

back of this now anytime you buy a

system board this plate pops in and pops

out so it doesn't matter if you have a

generic case and a generic motherboard

you can pop this portion of the case out

and put the one that comes with your new

board in so it matches up so let's set

our case back

down you want to take your system board

make sure that your components are

facing the back you want to go in and an

angle moving all your cables out of the

way you want to make sure that it

matches

up with all your components in the back

[Music]

make sure that nothing is poked out make

sure that you're all in the right

place and you want to make sure that you

can see your screw

holes and that they're matched up as

well again when you're putting your

screws back in you don't have to to Bear

down on them just make sure that they're

snug make sure that the system board

will not

move it doesn't jump

because as you plug components into it

you don't want it to

shift the ones back here by the by the

back of the system board are the ones

that are a little more tough to get to

because of the lip on here just you can

use a SC shorter screwdriver or an

actual longer screwdriver just to get

the uh get your your screwdriver away

from the edge

there the main concern with the screws

is you want to make sure that all four

corners Corners are tied down or

anchored you can short a system board

out without with the wrong screw or with

not having a screw uh added could uh

could add a short to the system board

which will cause your system board not

to power

up so make sure that you don't have

anything except for the brass inserts

underneath where you're screwing these

two and once you have your brass inserts

everything else should fall right into

place okay we're going to add the CD ROM

back to your uh back to your

system you want to make sure your sated

connectors the same ones that are on the

board system born the SATA and then your

power say so you want to slide it in

from the front until the front piece

matches with the front of your case and

your screw holes are lined up you want

to take your screws you want to make

sure that they're snug you don't want to

you don't want to have

to bear down on them too hard you just

want to be able to get them

into place to where it holds the CD ROM

in

place now that you're CD ROM's in place

we're going to add the hard drive back

your SATA connectors that are on here

this is power if you if you have ID

power and you don't have SATA power this

hard drive has both power connectors so

you can add a power connector similar to

this from your power supply if you need

to or just use regular SATA power I'm

going to add this back in what we want

to do is we want to find our

ledge where we want it we're going to

slide it back

in notice our screw holes are lined up

into the

slots we can slide it all the way as far

back as we

want or we can bring it as far out as we

need

to the adjustment is purely up to you

and the space that you

have take your

screw

line it

up doesn't slide either

way now that these two components are

back in we're going to add the power

supply we will add a PCI card uh all the

other components are in but I want to

add the power supply now to show you how

everything plugs back into

place power supply will go upside down

just depends on the on the back

angle you want to go in at an angle up

turn it straight slide it forward you

want to match up your holes your screw

Hol like most power supplies there's a

ledge on top

underneath that'll help you hold it in

place so when you're ready to screw it

in you line up your screw holes you

screw your power supply back in and this

one you want to make a little more snug

than the rest of them this has this is

all your power here so you want to make

sure that it doesn't uh it doesn't come

loose now your power supply is in snug

it's not going anywhere now let's plug

in our 24 pin power

connector there 24

pins on your system board it has 24 pins

your plug your squeeze um pin is on this

side right here that locks and unlocks

them and there's a there's a ledge on

the edge of your power connector there

so you just line up your

pins with the holes that are there and

push until you hear a snap and it's

locked into place your four pin power

connector again your clip there's your

power connector there there's your clip

there's a ledge on the a lip on the edge

you line up the holes it only goes one

way it won't go the other way and push

until you hear it until that clip

clicks now we want to add add power to

the rest of our system this is power

this is a power plug that we can add for

the CD

ROM add that power

back again it only goes One

Way power for the power for the for the

hard

drive power is

there

now your SATA plugs SATA plug for the CD

ROM SATA plug for the hard drive exactly

same

setup the difference is this one's kind

of a 90° angle which allows it to uh to

be put in this way the the P the the

system board I mean the hard drive

doesn't need it cuz you got more room

over here they do this in tight spots uh

where you can get to them a little

easier so our hard drive zero sata2 0 is

going to plug to the to the system board

notice the L shape on this one as

well there's the there's the connector

for it we going to push until we click

here it

click take this side again with the L

shape sideways L and we're going to plug

it to the hard

drive push until you hear it

click just like that and we're going to

do the same thing for the CD

ROM does it matter what port the CD ROM

goes to there's SATA zero then SATA 1

SATA 2 and sata 3 does not matter choose

SATA one the next drivein

line you feed your cable up and you plug

it against your CD ROM you want to try

to keep your cables as neatly as

possible that way you're they're not

running into your fans and you you're

not cumbersome and then you have your

other cables that plug into your system

board as well so let's start off with

the audio audio cable and if you

remember the audio plug was back here

notice the pins on this have a certain

pin out there's there's five pins then

there's three and number four is missing

and we have five on the other one as

well the same pin out as on

this we have five pins we have three one

missing and then

five so we want to make sure we line

those up

correctly and push all the way

down now we want to do the

USB and the card reader notice the pin

outs are a little different on this

one you have five then you have four and

then the last one's missing on that side

so you find your pen out the way you

want it on

here slide it into

place do the same on this one slide it

into

place this is a power connector for a

fan on on all power

supplies your power connector main power

is going to go red then black then

yellow anytime you plug in to another

Power connector you want to match up the

colors and they snap right into

place this one doesn't have red and

black so we want to find out we want to

make sure that power is the red is going

to this power here so we want to go

ahead and Slot it in place as well

negative this is our hard drive

LED and this is our reset

switch so those plug to this port right

here you're going to have to find where

the color codes on this but if you'll

notice it tells you which where each one

of them plug

in so if it's closest to this it's on

this side if it's on farthest away it's

on the opposite

side now that we've uh we've got our

cables plugged in connectors for the

front panel Let's uh let's install the

PCI card with the PCI card you uh make

sure it's lined up in your empty slot

and then you push down here and it snaps

into place and your screw you got to add

your screw back to it put your case back

on last thing we're going to do is put

our panel back

with where they go slides right back on
