But please remember, please remember I cannot pay my mortgage with passion.

I cannot pay my bills with passion.

I do need cold, hard cash.

And as we all know, YouTube has become a very hostile place for earning money for content creators.

So please think about joining Eli, the computer guy dot com or failed normal dot com to get other content.

That's not necessarily on YouTube and help support these projects that I d'oh Hello again.

As you know I am Eli.

In today's class, we're going to be doing an autopsy of a desktop PC.

So essentially, we're going to go in and we're going to rip apart this desktop PC, take a look at all the parts inside and give you a better idea of how all of the components go together.

So the glass class that I did, I was talking about all the different parts, the CPU, the memory of the storage, the motherboard, blah blah, blah, blah, blah.

And so you have an idea of what all these parts d'oh!

And now that you have an idea of logically what they dio.

It is good to see how they're physically all put together.

So, uh, what I did actually, for this whole A plus, Siri's, um, in order to have a computer, I could just bang up and destroy and not really worry about how much it cost.

I went to Micro Center.

So Micro Center is a local computer shop, and I actually was able to buy this computer for 100 and $9.

This is actually the Dell with a Dell computer.

It has a Windows 10 professional license to it is ah, Intel duo or whatever from like five or six years ago has five gigs a storage like they're five gigs of Ram.

About 250 gigs of storage.

Got an optical drive.

Basically, it's an all around good machine.

This is the type of computer I would suggest that you go out to buy in the beginning.

Now I know everybody wants to build their own computer.

Eli, I don't want to buy some used piece of crap.

I want to build my own computer.

Well, the thing is, building your own computer actually gets to be a bit pricey.

So this was 100 and $9.

All told, all told, optical drive, hard drive Ram the whole nine yards You have to stand.

Understand?

When you go out there to build your own computer, you know, power supply will run you forward your $50 case or on your 40 or $50 our drive old running 40 or $50 CPU is gonna run you amount of money.

So even if you go out and you buy it in, you basically assemble a low cost PC.

You're going to get a very piss poor quality PC for somewhere between 2 to $300.

And so you're going to spend that amount of money, and it's still gonna be a pretty crappy system, To be honest with you, the case I talked about that in the safety class right there.

The case is probably gonna have all kinds of sharp metal coming off.

It is just not gonna be a good thing.

So the nice part is, you go out there and you buy a used machine like this and you can go in and you already know that it works.

That's an important thing again in the beginning, when you're learning how to do something, you don't know if a parts dead on arrival or you did something stupid, right?

Is it?

Is it is it that the power supply failed?

You have a bad power supply or is it that you did it?

Plug in the power supply the correct way, right?

When you buy, we try to assemble a computer from the get go.

You don't know those things.

What's nice about buying something that's already supposed to work is you plug it in and if it doesn't work, you return it and get another one.

That does work.

Basically, you don't have to start at square one.

You have a machine, you already know.

It has all the stuff it's supposed to have.

And then you go from there.

The other thing that I do like about going out there and buying a used l or use Lenovo I personally hate HP with a passion.

My opinion, my pity.

I hate HP with passion, but again, if you go out there and you buy a decent refurbished of, you know, brand name vendor is a lot of things like the case the cases will be a lot better and easier like this case in order to get into it.

There's just this little there's just this little lever up here.

You pull the lever and the case opens up.

And so one of the nice parts do as as you're learning how to do things you're not As I sit here enough to fight with it, you're not having to fight with cases and stuff so much just to get parts to go together, right so you can learn how to install a PC.

I card.

You can learn how to install an operating system.

You can learn all the basic stuff once you feel comfortable.

Then you go when you buy your 10 80 T I graphics card and your insane stuff.

After after you've basically killed the $100 computer again and things like education, that's what you have to think about when you're learning how to do what you're doing.

When you know that electricity can cause a lot of damage to components, do you want to learn on ah, $100 piece of crap system that you're just gonna throw it in the recycling bin once you're done?

Or do you want to learn on something where the graphics card alone is gonna cost me $800 saying these kind of questions you have.

Ah, So in order to crack into this thing or to crack into this thing, I have my handy little screwdrivers here again.

Just a nice little set of screwdrivers like this Will do you find for almost all situations for desktop PC support.

And then I brought the pliers.

I don't think I need the pliers.

Probably don't need the players.

Was just nice to have a good set of pliers sometimes when you need to pull out parts.

So basically, with these, we're gonna rip this thing open, take a look at how all of the components go together and ah, really show you what makes a desktop PC and what you should do what you will be looking at when you crack one.

Open yourself.

So this is the desktop PC we're gonna gut quicker than Susan W guts the hopes and dreams of aspiring YouTube content creators.

Ah, what does that mean?

I was kind of mean.

I don't mind, though.

There's a certain point when you're just like I want to be mean.

There's a certain point in life when you're like Oh, I'm trying to be nice.

I'm trying to get along Then there's a certain point where you're like now we're to the point that that I want to be mean.

But basically, we're gonna crack this little guy open.

So, as you can see, looks like a pretty normal computer.

I got your USB on the front, got your optical drive has has a smaller, smaller bay.

If you want to put something in there, if you flip around, you take a look at the back of it.

You can see you have the normal ports going on here.

We have a graphics card down at the bottom.

Then you got your com port your network card, USB the whole nine yards.

So again, although this is an older computer, by normal standards, it's a It's a rather modern computer and any kind of desktop computer that you're gonna be ripping apart Maur or less is gonna look like this.

Like literally.

If you buy something from like an expensive computer from this year, it may look a tiny bit different, but I'm gonna say a tiny bit different now.

One thing to realize with this particular desktop computer is that it's what's called a low profile desktop computer.

So although it's big, I mean, you take a look at this thing you're like, uh, compared to a lot of the modern stuff coming out.

There's nothing about low profile.

This doesn't look like anything that you would call a low profile for a desktop world.

It is basically what low profile means is that it's thinner.

It's thinner than a normal desktop computer.

Why that's going to be important is for your expansion cards.

So when we crack this open, I'll show you.

But this is the normal size of the back plate for an expansion card when you have a normal sized that stop computer.

This is how big the back plate for the expansion card is for a low profile desktop.

It is that big is smaller, so it's It's sometimes called a low profile desktop or 1/2 size PC.

I card one of the other more or less.

This doesn't matter for a lot of things with that stop computers other than the expansion card.

So I actually added my own graphics card to the system.

And so when I did Ah, add the graphics card is I'll show you what I cracked this thing open.

I had to get a low profile graphics card because it's simply if it had used this plate, it simply would have been physically too big again.

This is just one of those things you'll learn as you go in the world.

But just keep in mind.

If you're looking at that stop computer and it seems a little thin and you're gonna wanna graphics card or a sound card or any kind of expansion card, you may have to buy a low profile card instead of the regular size car.

That's one of those things to be thinking about.

And with that, let's crack this thing open.

So with this, what's nice is again we have this little lever on the side.

And with that, what's cool is you just pull the lever and the case pops open.

This is what I talk about when you when I say bye, in a good case, why buying a good case is valuable, especially in the enterprise world.

Now, if you're gonna buy a desktop computer, you're gonna symbol a desktop computer and you're really never gonna take it apart, like ever, ever, ever, ever.

Then the case, you know, as long as you don't, you know, need a tourniquet while you're putting this thing together originally.

Ah, you seal it up when you're done, you should be fine.

But especially when you're dealing with lab computers.

When you're dealing with computers, you're going to be pulled, pushing and pulling stuff in a lot.

You want a good quality case because it's just so just being able.

I mean again, if your new when you haven't dealt with cases, I mean, it's nice that being able to put on or take off the side is literally this easy with some of them with some of the cases, the inexpensive cases, you basically have to pull out the pliers and a hammer every time you want to do this.

So having something is easy, is that again?

Right now, it may not seem like a big deal, but it really does matter.

So now we start taking a look at this thing, and so when we're looking at this from the top, we can start to see what's going on.

So this is the motherboard right here sober.

But everything's connected to the motherboard.

This right here, this black thing.

Basically, this is a cooling cow.

Also, a cow forces the air to go in certain directions.

So underneath this, you can't really see it where?

Yeah, but underneath this, this is the heat CPU, heat sink, and so underneath that he sink.

Is them a CPU, so I can take a look at it.

I can go.

Okay, so this is the CPU.

I look at this.

Okay, so this is the optical drive tells me it's a DVD writer again, depending on how old you're, the desktop you're dealing with is you should just take a look at this to see what it is you know.

Is it just a CD?

CD is a just a DVD player.

Is it a CD writer?

Is it a DVD writer?

So on and so forth.

Nowadays, everybody, everybody's gone with thumb drives, so it doesn't really matter so much.

But this might cause you some issues, especially with these old these old optical drives.

E mean, especially because people use them so little they don't actually use them a lot.

You might have a really old optical driving there.

You may have, like, a 10 year old optical drive that's just gone through a few different computers.

And so it may be something like it's, you know, you're like, Why?

Why can't I install the operating system and then you find out?

Oh, because I have OS DVDs and this is only a CD player.

So you just look at something like that and you can see we got a power supply here.

You look down here.

These are our Ram Bram Sticks.

Aram.

I can look down.

I can see that under underneath the optical drive, the hard drive is here And then, of course, we've got the graphics card right here.

So I have a basic I have a pretty clear understanding of what's going on.

You may also see with, like, enterprise level computers, like when you buy Dell or Lenovo, you'll see little but him like this.

So this is a little button.

What this does is this the text to see whether the case is closed or not So within bios, normally you can configure to say whether or not you want the computer to boot if the case is open.

So this is just one of those things to realize it exists.

Sometimes you can see there's a little cable here.

Sometimes this can get pulled out, or somebody somebody can do something stupid and pull it out.

And so if you're having weird like, it won't boot or it's giving you weird errors.

It might be something like this has been pulled out.

But this is the basic idea of what we've got here.

So we start looking at this and we start thinking Okay, So what?

What, are we gonna pull out of this first?

And so Hey, what the hell?

Why don't we pull out the graphics card?

Since we're talking about PC I cars before Now with this, this has an interesting set up.

So normally, um, with these Well, I guess I could do it this way.

So what we can dio is with a lot of these types of of expansion cards.
