Computer Basics: Hardware

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 this is a power LED positive and 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 on make sure that the uh grooves line up with where they go slides right back on put your thumb screws back in and you are back to [Music] normal
