STEP 1 : Materials Required

This tutorial is intended to assist you in building a basic PC. There are obviously a plethora of possible PC configurations and hardware that you could put into your new PC if you choose. But, what we are trying to do here is help you put together a basic PC. For this reason, we are only requiring the basic components and tools to get you up and running.

Tools Required

  • Screwdriver – A Phillips-head (cross-point) screwdriver is what is used in most PCs.
  • Screw Extractor – If you have surgeon’s fingers you may not need this. But, if you’re human, it is likely you might drop a screw into your PC during this procedure and be too big-thumbed to get it out. A screw extractor can help you grab those screws and get them out without messing with the hardware. You definitely do not want to run your PC with loose screws in there. It could cause a short circuit.
  • Flashlight – Unless you are in a fantastic lighting situation, you will likely need a flashlight to get a look of the landscape in your PC while you’re working.
  • Tweezers – May be helpful for you in switching jumpers later in the tutorial.

Hardware Required

  • PC Case
  • Floppy Disk Drive
  • Hard Drive
  • CD-ROM Drive
  • Processor
  • Processor Cooling Fan
  • Motherboard
  • Memory Modules
  • Power Supply
  • Video Card
  • Keyboard & Mouse

To build a basic PC, you will need at least a motherboard, a memory module, a processor with cooling fan, a power supply, a hard drive, a floppy drive, a video card and a CD-ROM.

Most electrically sensitive hardware comes in a static bag which is designed to protect the electronics from static electricity shock. Leave your hardware in these bags until you are ready to install them.

Software Required

  • System Disk
  • Device Drivers (these usually come with the hardware above)
  • Operating System (for the purposes of this tutorial, we will assume you are choosing Microsoft Windows as your operating system – PC Mechanic has lots of great information on Linux and other alternatives)

Cables and Miscellaneous

  • Drive cables
  • Motherboard spacers (usually come with the motherboard, but are used to space the motherboard up off the mounting plate)
  • Screws (usually a whole pile of screws will come with your PC’s case, but if you are using a case you happened to have around, you will need to collect some screws)
  • Power cords (for both your PC and your monitor. They usually come with the hardware when you buy it, of course)
  • CPU Cooling Compound

    ummmmm just a question i have several burnt out computers which i know some parts proabaly still work i/e like the ethernet card i was wondering how you can tell who makes it and where i can possible get the drivers for it since i dont seem to have them anymore thanks

    • Jay Master

      WEll u can buy a new Dell Vostro computer, or build your own with a Core 2 Quad processor. Core 2 Quad Processor performs up to 67% greater than Core 2 Duo. it will be great!

  • Tony

    Hey, im looking to build my own PC just for schoolwork.. we only have a laptop at home and its not really convenient when my sister has to use it aswell haha. So i was wondering how much it would cost me to build a decent PC capable of running apps smoothly, just for work and such? I already have a monitor (19” Samsung, woo) and a keyboard and mouse.

  • Eddie

    Hey, by any chance, is the floppy drive absolutely necessary? I mean, I don’t own a single floppy disc so it would be an absolute waste of money to get one. Plz respond,

    • Fred

      I don’t have an answer, but I have the same question–Why would a floppy drive be required for a system put together in late 2008? Seems a waste to me.

  • Matt

    Hey, what brand would you consider better overall?

    Nvidia

    or

    ATI

    Thankss =]

  • brody

    I don’t think you will need a Floppy Drive. I think this was just put in because a lot of people have Older things that they used to own on Floppy’s. If you do need one…Where can I get one nowadays?

  • http://none Mikifin

    The mechanics of building a computer are fairly straight-forward. I have taken out and replaced most of the components if not all of them in many computers. I have never had to purpose-build or had the desire to build from scratch my own PC. I have never wanted to bother with the process of figuring out how to select all the components and sort through all the choices.

    The task that seems to me to be more difficult is reviewing, selecting and matching the components. It would seem to me that would itself make a more insightful article.

    An example: say you wanted to build a PC that would run all the Linux distros, or a computer that would be able to run all the WinX versions, or all the WinX versions and the largest range of Linux distros how would you do this? How would you research and select all the components to be able to accomplish this (and the reasons for the various selections)?

    Another example would be to write an article that would step through all the mistakes (at each step) that could be made and how to look out for and correct them. For instance, I think you should assemble all the parts first in a clean, dry, well lighted, static free environment etc. and first examine the parts (as well as their directions specifically). From this examination (during my various repairs), I have often found conflicting information in the parts packages (how do you resolve them) and discover, that you indeed need different tools i.e. a nut driver instead of a screw driver for some of the parts.

    Screwing together all the parts is fairly straight-forward and while important to learn, the foundational decisions prior to actually assembling the parts if often more or equally as important.

    So… yeah… iv read some of the things on here… conroversy about dells Etc. Honestly, yes, building a computer is a WAY better way to go

    Scavenging pieces from peoples Old computers, going to Re-PC or something and selling them, and then buying the parts with the money

    i made a computer with these specs for just around $400 out of my own pocket:

    Ubuntu
    1.3 TB hard drive and a 160Gb that i put my OS on
    4Gb RAM
    NVIDIA Quadro2 MXR Multi-monitor graphics card
    D-Link Wierless N+ Adapter
    AND LIQUID COOLING!!!

    Go dumpster diveing once in a while, you’ll have a grand time!!!

  • i built a comp for the first time

    I like mid to high-end Dell comps (eg. XPS line). they are pretty durable and have some room for upgrade unless you choose the most expensive options they offer when you build a system on their site. And there’s some room for expansion as well but just not as much as what you get when you build your own.

    Basically, Dell comps are made for the average users that want mid or high-end comps but not for real enthusiasts or super hard-core gamers. I totally see why most of the people go for HP, Dell, etc. I bet 90% of the computer users in this country never open their computers to add a card etc anyway. And only do like one upgrade in the computer’s lifetime caz they aren’t that obssed with keeping their comps up to date. Besides, it’s probably nice to know for most of the people that if their comps have issues, there’s one phone number to call for warranty support as opposed to having to diagnose the issue by themselves and contacting the manufactorer of the mulfanctioninig hardware. In addition, those pre-built comps aren’t expensive anymore. A 1000 dollar system that you build will be equivalenet to 1100-1200 dollar Dell comps but hardly no more than that, but for the extra they charge, they offer 1 or 2 year remote diagnosis / in-home service, etc. so, in the end you pay about the same.

    It’s about how picky you are about what your comp has. Most of the people don’t really care so long as their comps allow them to e-mail and surf the net, download music, watch DVDs, and do some casual gaming.

    • Ian

      Concur. upgraded my Dell Dimension 8250 with RAM and vid card to keep it running somewhat strong the last 6 years. But ready to build. What parts do you have? Will build i7-920 comp. thx

  • Peter

    Is there any difference between a system disk and the disk that the operating system is on?
    If so then how do I get a system disk?

  • dale

    Oops. 1.25 gb of RAM. I deserve to be pasted for that typo.

  • Alan

    I don’t know why you all dis Dell. I have had tremendous success with products I purchased from them. My Canon lens has never failed, my Creative Zen works great, my Vizio HDTV is loved by the entire family and the Xbox 360 rocks with guitar hero. OH…..none of those were actually built by Dell.

    By the way, HP is even worse, Ahhh……………….

    Take ownership, build your own machine!

    • Craig

      lmfao! no doubt man!

  • payne

    Just got i7 this thing rocks!!

  • cory

    DELLS SUCK my cousin built a computer for £350 which has better specs than a £1000 dell xps

  • Kirby

    DELL does make a decent computer if you have no knowledge of what you’re doing and if you don’t want to learn. As for making the Best computer for the Best price that’s another thing.

    The truth is if you have two computers, one built by DELL and one homebuilt, and you spend the same amount of money on both, the Homebuilt should be way better than the DELL.

    But the problem is with Home Built Computers you don’t get the customer service (no matter how bad it is). You also don’t get the warranty on the computer as a whole. Sure, you can get a warranty on all the individual parts, but that’s only helpful if you know enough about the computers to know what needs to be sent in (which lets face it, if you’re building the computer then hopefully you know enough about what you’re doing to know where problems are comming from, but then again some of us actually think a DELL computer will be up to date 20 years after it’s been purchased).

    So basically, DELL can save you a headache of buying your own computer but anybody saying they’re cheaper than building your own computer is just lying or ignorant.

  • Mam89

    A lot of people reading this guide need to understand also that building a computer really isn’t for most people, simply because of the person not feeling up to it and there not really being any hands on help. Thats where most of those horrible chain off-the-shelf computers come in which just overcharge for junk. Because people know they work (or are supposed to work anyway) when you buy them, no hastle.

    However, there is an in between ground often, in most places actually. Most cities and small towns even, have local computer places popping up, I know because I’m actually interested in going into the business. These places are probably the best place for easy and cheap service when it comes to custom computer building if you check into them. You can actually talk to a real person (not a phone conversation) and get the whole depth of the situation. Most places will even let you bring them the parts if you have them and they will only charge for the build time (still saving you $100s compaired to retail hulks like what Dell offers).

    So, if you’re like me and a growing populace of people that like building, go for it and remember that static strap (nothing worse than a fried motherboard!!), if you’re not up to it but still want to save money and help support a local business, try hitting up the little PC repair shop around the corner for build requests (and ask if you can bring in your own parts to save yourself a little extra money).

  • Joe (not THE joe)

    I agree with mam89. I WAS one of those people that bought ready to use computers from HP and Sony (NEVER DELL) for convienience until a friend of mine who builds computers for a living laughed at me when i recently bought an HP m8530f for $800.

    If you take the time to learn a little about computers, which costs $0 @ google.com and know where to shop for parts newegg.com ANYONE can build a great reliable computer for far cheaper. And as for your local computer shop its a great way to get a little technical advice when youre stuck on a build and pretty cheap as well.

    The bottom line is….. pre-built computers are built to last for the length of the warranty NOT for the ability to upgrade or quality of the system.

    Dont waste any more money….. I SAY BUILD YOUR OWN!!!!!

  • Leonard whos little about computers

    2 questions here.. where would I purchase all the hardware required?… and secondly I have a Rad eon 9600 pro which I installed in my last computer as an upgrade as well 1 GB of ram (DDR3) it would be a real shame to put these to waste… would you think I could build a computer that could hold 2 graphics card? I actually don’t really like the 9600 pro but better to put it to some good use then to sell it for the half the price I paid for it!

  • Leonard whos little about computers

    Actually how many components are recyclable I have a windows XP with the above in my previous comment, it is wireless for internet a CD (DVD R/RW) player, key board, mouse and a floppy disk

  • Allen

    Does someone have to install a floppy disk drive in a computer. Does anyone actually use those anymore? Seems like a waste of space and money.

    • Gary

      You don’t need a floppy. I’m not using one its only if you have old floppy disks that need to be read.

      (You’re right it is a waste of time, money, and space.)

  • James

    Where is the best place to buy all these computer parts?

  • sharon

    how will i know all the parts will go together?

  • cirilo

    does anyone knows where is the best place to buy all the hardware…you know good and cheap or a least ideas of how to get them.

  • Brandon

    I have the same question as James actually. What’s the best (cheapest) place to buy all of these parts?

    Frye’s?
    Newegg?
    Tigerdirect?

    • Ian MacFarland

      Depends on the parts and deals going on. I upgraded my Dell Dimension 8250 with a vid card from TigerDirect a few years back and got some mail-in rebates but they may not do that anymore. NewEgg is also good. No experience with Frye’s. Since my Dell is going on 6 years now, I’m going to build using a barebones kit or separate parts from one of the above vendors. Will hit up Craig’s List to get rid of the Dell for $200 or so. Replaying the same games just gets old.

  • Orla

    I have a Dell desktop can I use that tower to build my own computer?

  • Gary

    Um, excuse me but it does not cost $750 per computer!!! For me it only costs $205.95!!!!

    (Everything is off of http://www.newegg.com except for mouse and keyboard)
