How to Build a Computer - The Complete Guide

by:Changda     2020-06-13

Making a computer is a bit like playing Tetris.You have a bunch of odd-shaped pieces that you just need to assemble together in one way, so you need to pick the right pieces or they won\'t be together.Apart from that, the assembly is very simple, and there is almost no tool to do that.Yes, you need to have some dexterity and patience, but it shouldn\'t scare you to the first computer store, open your wallet, and the guy begging for Commission work takes all of your stuff.The most important step so far is to make a list of materials...What parts do you need to buy?You need to do a little iteration to do this.What part do I want to give me the show I want?Are they compatible with each other?No?Which parts can be compatible?Do they give me the show I\'m looking?No?Wait.In the end, you will narrow your list down to something manageable and then you will have to practice it over and over again, but this comparison (what do you want & What Works) there is (what is in stock at the local parts store), and maybe there is (within my budget ).It\'s painful to do this, and it usually takes hours on one computer to do online research on multiple store sites.However, once you\'re done, assuming you haven\'t made any mistakes, the rest of the process is actually a breeze, especially now, as the parts are better designed as \"tools\"less\\\", color-Coding, easy to connect.It\'s going to be your second nature after creating a few batteries, you can take advantage of you by charging others for making computers for them or simply making your own computers much cheaper than you buy in a store.Also, it\'s really a custom rig designed for you, with nothing missing and nothing you don\'t need or want to pay.The interesting part is here now.You have to look into every component you need to build this computer.You need to look into what is compatible with what, whether it is enough to meet your needs, whether it is cheap enough to meet your budget, and whether it can be purchased in your area.It\'s a lot of variables, so hopefully a lot of compromise will be made.The easiest way is to call it for the first time in about 20 minutes and get a rough list.Then go back and check for compatibility.Highlight the offenders and then look specifically at the sections to see if there are alternative sections that work with the rest.If not, you may have to replace a matching component.After an hour or two, you should have a valid list after this scan.For compatibility, go through it again, check yourself quickly, and add up the total.Then check the inventory in your local computer store.Adjust the parts as needed to meet the cost and availability, hoping not to break the delicate balance of compatibility you just worked hard to complete.You can think of it as a need for you to push a list of computer materials, but in reality it tends to be the opposite.Depending on how bad the hardware is, it\'s in a different price range.The ridiculous level of performance of a given component can only be guaranteed by a specific type of user.For example, if you\'re going to buy a graphics card, it doesn\'t make sense to buy one for $100.It\'s better to buy a good one for $300.400.At this point, you are pretty sure you are a super user or player.If you have a good graphics card, you have to have a good CPU and motherboard as well as enough RAM so that none of these things can bottleneck your expensive graphics card.Again...gamer.Let\'s face it. if you don\'t play games, you can get away with it with the system computer and be very happy.I just made a $300 computer for my friend that can play HD video and play DX9 video games on maximum quality and do everything you can think.When it comes to it, the most expensive part of the computer goes hand in hand with the second and third expensive parts of the computer.You will not spend money on one person or on others.The only benefit of the computing cycle is the math and the fast transfer of large amounts of data, so unless you do CAD for engineering companies or work on the next version of Avatar, you may go online, watch youtube and use Twitter and other daily tasks that you can easily do on cheap smartphones.Don\'t try to insult a few people who are good for the base use of the rig or something.I just said that most people need a computer because their old one is broken and broken...Or they are a gamer, and their machines are not good enough now, or they plan to dig bitcoin with it.I will divide yourself into one of these three categories.Unless you are the kind of person who likes to leave a bunch of loose parts on the carpet waiting for a short circuit, fire or step on, you need a case to tie it all together.This is really the backbone of your system, and so is the chassis if you are a car type.This case has many purposes: it organizes the internal organs of your computer, prevents them from short circuit to each other, protects them from external hazards, and provides a general electrical \"grounding\" for the entire system \", all buttons and front panel ports are provided, allowing you to easily access all removable media drives and create paths for airflow to properly cool all components.It also looks cool and you can take it out of the pimps so your computer has its own personality...if you want to.There are some very important things to consider when you buy a box.How big does your computer need?Case size is often called \"Tower \".Mini Tower, middle tower and full Tower.Larger towers are needed to accommodate more internal devices such as drives, cards and larger motherboards.For smaller motherboards, they also have Installation points at times.You need to know in advance how much courage your computer has, determine the corresponding motherboard size you need and the number of drive bays you need, and adjust the size of your tower accordingly.If you have questions, you can take the middle tower almost at any time.This is a safe bet of 99%.Since you are adjusting the size of the chassis or the \"tower\" for the motherboard, please see if the chassis supports a micro ATX (uATX), mini ATX and/or ATX form factor.From the minimum to the maximum, these are the general size of the motherboard and determine the installation point inside the chassis.You want your chassis to have the mounting point of the motherboard size you plan to get, otherwise you will be S.O.L.When you build this thingIn short, if you want more cards and memory and decide to use the ATX motherboard, get a chassis that supports the ATX form factor.Make sure you have a fan in your case.If not, read the fan size box and buy one.This situation provides cooling and if you don\'t have at least one fan you will get rid of it for the time being, but in the long run you will ask for serious trouble and heat overload issuesThe front panel of the chassis contains all USB and sound connections, so you want to make sure you are satisfied with this and that all physical ports are supported for the motherboard connection.Check out the board features to learn about this.Try to get the \\ \"tool-less\\\" case.Nowadays, they are becoming more and more common, replacing nuts and bolts with cams and levers.CD/DVD/Blue-how manyDo you want Ray or the front panel (high-end sound card for example?Make sure there is enough.25 \\ \"drive pays for them.How many hard drives or floppy disks do you want (don\'t laugh, I\'m still using them )?Make sure you have enough 3.5 \\ \"those drive brackets.-Go for \\\"tool-----Make sure you have enough 3.5\\\" and 5.25 \\ \"drive bracket.-: $40 -This is a small heavy metal box with lots of wires and connectors inside.It converts your 120 V home AC power supply into a variety of DC power supply currents that your computer needs.Connectors are also unique for what they insert.First of all, everything in your computer consumes electricity in Watts.If you can, get a general idea of how many watts you need by looking at the specifications of each part.The power consumption of the graphics card, CPU and motherboard is large.If you add 150 watts to it, you will usually be fine.In most cases, your normal computer should be able to use 500 watts, but when something explodes, you can do math or suffer the consequences, hopefully the power supply, not the graphics card.Check the connector on the power supply.They are all listed on the back of the box.To power the motherboard and CPU, you need a very specific set of connectors.Sometimes it\'s 20 stitches for mobo and sometimes it\'s 24.The CPU can be 4 or 8 pins.Each of your hard drives and optical drives requires a SATA power connector that looks like a one with a little L-There\'s a key in it.Make sure you have enough connectors for all power items in your computer.Graphics cards almost always require their own capabilities.It used to run directly from the slot, but now you need a 6 Pin (2x3) connector or 2 6 or 6 and 8.The graphics card will specify, so check the PSU to see if it has the correct connector.You may need a large white molex connector or 2 chassis fans or old drives you can try to clear white 4-pin connectors.--: $30 -This is the most important part of PC.It is the architecture of the whole computer, and everything can be inserted into it.Generally, the size (shape) determines how much you can insert.Buy an ATX if you want a power PC or gaming PC.If you are making more budget computers, buy a uATX.They are cheap and small.The most important parameter when selecting the motherboard is the socket.Don\'t screw this up.Let me say it again.Don\'t choose the wrong socket.The socket is what you plug into the CPU.This is a large array of holes that must be perfectly aligned with the CPU.This is why you need to select the motherboard at the same time as the CPU in order to purchase the motherboard at the same time.Check the processor slot type and select the matching motherboard.Make sure the motherboard can also handle the power consumption of the CPU.It should tell you its rating.Check the RAM slot.Check the speed and number of support.Make sure your RAM is at the right speed and you get enough GBs given the slots available.View expansion slots including video slots.You will want to have PCI Express or PCI-With a high enough version to support the E slot for the graphics card you plan to purchase.Make sure the card has enough space physically, as many cards take up 2 slots, sometimes very long, and may hit other components on mobo, because manufacturers are not always smart enough to make room for the biggest cardsIf you have an old card with PCI slots, you have to find a mobo with those slots.Check the rear panel.All the ports are here.See if it has what you need.If you have old printers or serial devices, you either need these ports or some sort of dongle that converts them.Check if you have enough USB slots.Check if you need a ps/2 style (round plug with pin) mouse and keyboard connector.Check if it\'s integrated with the LAN (it\'s not possible without this now ).Check if it integrates video and sound.If there is a port, the video is either integrated on the motherboard or on the CPU so you don\'t need a graphics card.Same voice.You don\'t need a card if there are holes.-----$50 -This is the administrator of your computer, the brain that operates.While graphics cards are good at doing a lot of tedious and repetitive math, the cpu is good at doing the ever-changing complex tasks they don\'t specifically design to do.So it\'s very important to make sure that you don\'t create a bottleneck for your PC by selecting a weak CPU and pairing it with a strong graphics card, otherwise you\'ll waste money.The Cpu is characterized by speed (MHz, GHz), number of cores (which determines how much they can do at the same time), cache (which determines the speed of data retrieval with frequent access to information), power consumption (in watts), manufacturing process (measured in nm), it determines how many transistors can be installed on the chip and socket, this is important when pairing the CPU with the motherboard.Basically you want high speed but low power consumption and low cost.There\'s a trade-Because you can only walk too fast (~ 3 GHz), then you need more cores to further improve the computing power.Both speed and core quantity increase the cost, but you can look at the different combinations of 2 to see if you can get a price discount.Then APUs.These are recent developments in the field of computers, now more than cpu.Basically, it is a CPU embedded in the GPU (graphics core.Graphics cores were once included on the motherboard, but when you put them on the CPU, it reduces latency and improves performance, not to mention it reduces encapsulation space and system complexity.For those of you who buy a graphics card, you don\'t care about APUs.You can use them or not, it\'s not a big deal, but the APU is a way if you don\'t want to invest in a graphics card.Make sure you buy a CPU with a radiator.The CPU itself is a tiny chip, and the radiator is a huge thing with metal fins and fans.You can\'t run the CPU without a fan, but you can buy it like this and it\'s easy to go wrong if you don\'t know better.Try starting a PC without a CPU fan and it will melt on you in a few minutes...Or the BIOS is likely to fail-Security mode so that it does not happen.Don\'t let it go that far.Purchase CPU including radiator.It may be a hot paste that has been applied or applied separately.Before you put the radiator on top, you have to squeeze it on the CPU core.This is a liquid buffer that helps heat flow out of the chip faster.It\'s important so don\'t lose or erase it.----: $50 -RAM is a very fast temporary memory for frequent access to a large amount of information.It is very smooth and fast.If it weren\'t for RAM, your computer would have been stuck because even if it had just processed the data a second ago, it would have been constantly using the hard drive to process the information.There is a direct correlation between RAM performance (and capacity) and computer speed.Large Program and pre-gameLoad a lot of data into RAM so that the CPU can work on RAM easily.Therefore, you will want to know something about the most labor-intensive programs or games you expect to run.Games are a good choice because they rely heavily on RAM.Select a fully functional, shiny game and check the memory requirements.Usually 4 gb is enough, but people who only use Excel can easily live with 2 while others play MMORPG space empire, run 8 gb around Bitcoin mining operations in the background.Remember to check your motherboard to see how many slots the RAM has.If you only have 1, you may have to put all your memory in 1 \\ \"DIMM \\\", which is basically 1 chip you inserted, not 2, eachThe price goes up with fewer dimm but better scalability for the rig.Next check the speed of the RAM.For example, it measures a frequency of 1600 MHz.The motherboard will clearly show the supported speed, so choose RAM at one of these speeds, the higher the better, but more expensive.Don\'t Mix \'N\' to match.While you can mix capacity (1 GB and 2 GB dimm), you should never mix speeds (1333 MHz and 1600 MHz ).It can\'t work and can be harmful to computers.---: $15 -: Pirate ship, Mushkin, Kingston, G.There are now two hard drives.Traditional type with rotating disk and solid state disk.Solid state does not have moving parts, access times are faster, but capacity tends to be smaller and costs higher, as solid state technology is still in its infancy with traditional hard drives compared to long-term recording and manufacturing infrastructure.Both are very good options and it really depends on whether you want the limit of speed or the better value per GB.The hard drive is where all your programs and data are storedpermanently.That is, your hard drive will keep the data if it is powered off, but the RAM will be erased.However, unlike RAM, the hard drive is slow and the data should be cached somewhere before use.The capacity you choose depends on what you plan to store on your machine.If you like to put movies, games and music on your machine, you need a big hard drive.If you work on a computer most of the time, you will need much less.The hard drive is connected to the motherboard via a serial ATA connection or SATA.In addition to the power connector, you need a SATA data cable, a fine red cable with a small fine L-Black ends.The earlier hard drive used parallel ATA, which looked like a wide and flat ribbon cable with several strands inside and a gray rectangular connector at the end.These are almost non-existent today, so don\'t worry about them.All you need to do now is understand SATA standards.One or two cables will come with your motherboard for free.The hard drive (the kind of rotation in any case) rotates at various speeds, but most of the hard drives rotate at 7200 RPM.Don\'t be slower than this.A little slower.You can combine several hard drives together in a RAID configuration to protect data by copying data on different physical disks, or speed up data transfer by storing spare bits to access simultaneous development of 2 buses on different disks.Whether or not you do this depends on your needs and most users do not need it because it is not necessary for the average consumer to have this speed or level of protection.Server administrators may want to do so, though.----: $50 -Ah, let\'s get started :) This is what you guys have been waiting for players!Video cards drive all your love fantasies for video games and movies.It speeds up 3D graphics and renders clear movies at extremely fast speeds, while the rest of the computer is also playing.The graphics card is usually a huge double.slot, heavy S.O.B.Use the fastest bus channel on the motherboard, the powerful PCI Express 16x channel.If this is not good enough for you, some motherboards have two so you can run a pair of cards side by side.The graphics card almost always needs its own power supply and the PSU should have a special PCI-E Connector for graphics card only.Any good PSU has a pair of 6-pin cables and has the option to use a 6-pin and 8-pin configuration.If it is ready for \"Crossfire\" or \"SLI\" you will have more crossfire so you can use multiple cards.Not all PCI-The E slot is the same.There are different version numbers and sometimes they are not backwards compatible.You have to make sure that the card you are buying works with the slot you have.Both the card and the motherboard will tell you what version of the specs they support, so just match them up.In addition to the system RAM we mentioned earlier, the graphics card has its own video RAM.Any graphics-intensive application will specify the type and minimum value of RAM.Make sure the video card is the right size to handle the load imposed on it by any software you wish to use.On the back of the graphics card, you will have a port connected to the display.Including VGA, DVI, Display Port, S-Video, HDMI, etc.If you have an old monitor with only VGA cable, you may not be able to connect it to the new card.But if you buy a dongle that converts from DVI to D-you can still do thatSub (VGA).There will be no problem with the updated monitors as they may use DVI or display ports.If you want to do better than the integrated video on the motherboard or APU (provided you have one), expect to drop a few hundred dollars on a good video card.However, you can check the PassMark benchmark on the Internet, which will give you an idea of the ranking of various cards in terms of performance per dollar.This will help you get the best value.As mentioned earlier, the power of the graphics card is great.Check your PSU to make sure it has enough rated power to support the peak load of the graphics card, and for everything else, the buffer is about 150 watts.PSUs is often more than just pumping all the current to the first device that requires it.Instead, they distribute the current on different tracks, so even if the \"total\" rated power is 500 Watts, you won\'t get all the current for one device.Be conservative, either zoom in on the PSU at a healthy margin or reduce the size of the graphics card.Finally, check the physical size of your card.It \"should\" fit, but if it is particularly long or particularly large, it may crash with other components on the motherboard such as feverSink or capacitor.If there is any metal on the card shorts on the motherboard, you can blow the whole piece so it is better to check the size in advance!-Determine PCI------: $50 -The sound card is simple PCI-Processing 1x or PCI cards for all audio tasks that the CPU otherwise will undertake.In addition to uninstalling some work, they are also good at improving sound quality by using very high quality electronic components and sophisticated software.You can remove artifacts, add sound effects, and play the tone of the audio for the best possible experience.Gamers and musicians especially like to have a sound card because it provides higher fidelity.It also offers ways to connect multiple speakers, headphones, microphones, and digital I/O.They are usually low-power devices that run directly from the bus.They are also smaller and should not cause too much trouble to pick or install.Compared to anything else, you are more likely to have issues with the provider\'s driver support.-If you have a spare slot and really like high quality audio or games, please purchase the sound card.: $50 -These are fairly generic, the cost of running the factory components is not high, and they run the way they are advertised.It takes at least 1 set to install the software and play the movie, so buy a DVD Burner for $20.All you need is extra SATA power supply and SATA data cable, just like the hard drive you use.You need space for your case...a 5.To be exact, 25 \\ \"drive bay.If you find yourself loading a lot of different types of software and don\'t want to wait for 1 to finish, or if you want to burn down, having two drives is sometimes worth saving some time on multiple disks.I have 2.Usually I would say it\'s too much, but you won\'t go wrong for every $16.---You need at least one, five.: $15 -As far as the computer is concerned, the only thing you need to care about is whether there is a proper port to insert these peripherals.Keyboard and mouse are either USB or PS/2 these days if they are old.We all know what USB looks like, PS/2 is a circular connector with several pins inside, usually coloredCoded on the back panel with green and purple.The display will have a D-A small, ladder-shaped sub-type VGA connector with a rectangular DVI connector arranged with asymmetric pins inside, or a display port that looks like a larger USB plug.It can also be HDMI and looks very similar to the display port.The display uses its own power supply, and you should plug them into the same power strip that the computer is using to prevent ground circuit problems caused by poor housing wiring.The power consumption of the keyboard and mouse is very low, directly using the bus power supply on the motherboard.---: $5 -The first rule of making anything with an electronic circuit is to make yourself bloody!A strip of pick-up around your wrist and clip to the metal worksheet is cheap insurance against frying your new parts as you sit on the velour sofa on your carpet floor.If you\'re going to be an idiot, at least put the computer box on the floor next to you while you\'re working, touch it with one hand and handle the parts with the other.The second suggestion is to start with making a sub.Assembly of Motherboard, CPU and RAM.This is easy and can be done very comfortably on the table.Then you can put the whole thing in the box instead of trying to install millions of small cpu pins in the recessed dark cracks because you installed the Motherboard first.The third suggestion is to organize all the right tools and parts packages before starting.Take a small cross screwdriver, a needle nose clamp and a small flashlight.Then collect all the screws and stand bagsThe evidence attached to your case and find out what they are.Arrange them in your workspace so you can easily reach them.1) open the motherboard and place it in front and center of the workspace.Find the large square socket of the CPU and lift it up on the thin metal rod found on one side.It should be raised to 90 degrees and cause the socket hole to open.2) turn on your CPU and remove only the chip at this time.3) find the small golden triangle on the CPU chip and align it with the motherboard socket so that the triangle angle of the chip is aligned with the triangle of the socket.4) put the chip into the socket.There is no need for force in this step.No.If the chip is not immediately fully plugged into the socket, it will not queue up.Lift it up and check something (maybe the pin is bent?) Then try again.Remember, don\'t push.5) after the CPU is flush, push down the lever on the socket and lock it.You will hear a faint rattle.This is normal.6) remove the radiator and hot paste from the CPU box (if applicable ).Apply hot paste to the top of the CPU chip.7) There are Springs in the radiator-Like the bracket above, it grabs two hooks on both sides of the socket.Lower the radiator to the top of the CPU chip so that the end of the bracket is aligned with the retention hook on the socket itself.Install the end of the radiator bracket around the hook, then rotate the plastic cam handle near the radiator, which will tighten the bracket and lock it in place so that the radiator cannot move.8) Use the motherboard documentation, find the CPU fan pin and plug the fan cable of the radiator into the motherboard.9) open the RAM dimm and insert a very long RAM slot at a time, which is next to the CPU.Now, unlike the CPU, the RAM module requires a lot of power, so be generous and push down until the reserved tab at the end is clicked in place.Just make sure you don\'t push the dimm back.They only go one way.10) motherboardAssembly is complete.11) put the motherboard aside and open your case.Remove any fasteners, bags, etc.Open the side plate.Put the case aside and open your PSU.12) there is a groove on the sheet metal inside the shell, as the tray that must be used when installing the PSU.You will know that you have found the tray as it is the highest thing on the back of the case with a large opening on the back of the case that can be close to the back of the PSU.The PSU should have a vent with a fan and a power switch.Make sure to point out the back of the case and slide it into the tray.Screw the PSU in place using the correct fasteners and all the cables are hung inside.Try to keep the organization of all cables as the next part is tricky.13) grab your motherboardAssemble it and hover over the box to find out where it needs to go.You will know that it is in the right position as the back plate needs to be aligned with the punch hole on the case.14) there should be a back plate in your motherboard box.This is unique for your motherboard and needs to be replaced with anything on the back of the case that should fall off easily.Take out the stuff that clogged the hole in the box and plug the plate with force until it clicks.15) there should be small brass screws on the case with socket hex shaped head on it.These are called brackets.offs.Sometimes they have been installed and sometimes not.On your motherboard, there are several holes on the motherboard where the screws should go.The position of each hole must have a bracketTurn off with the motherboard on.The stand-The off can only be installed where there are holes to be queued.If you do not follow this step correctly, you can easily shorten the length of the motherboard, so only the brackets can be placedThe off of the motherboard hole will eventually appear.16) once the station-Install off, lower the motherboardAssemble back into the box and sit down on the standRemove and drive with several screws.This part will be difficult because the holes won\'t want to line up due to the annoying backboard and all the spring cards on the motherboard.When you try to drive the first few screws, you have to swing the plate in place while pushing the back panel.After that, the rest of the screws easily went in.Tighten all the screws (don\'t push too hard) and you\'re done with this part.17) before you start connecting all the wires (which is the trap I always fall into), keep in mind that every single one you connect will get in your way.Instead, put them all aside and grab your hard drive and optical drive.18) insert the hard drive into one ofo in 3.5 \\ \"drive the carrier from the inside of the chassis.Keep in mind that the distance of the SATA slot on the motherboard is important.So far, the cable only extends.Use the correct fasteners to secure the hard drive (the socket is facing the inside of the chassis ).19) select one of the 5 options.25 \\ \"drive the bracket, loosen the plastic board and leave a rectangular hole behind.Now grab your optical drive (like your DVD burner) and plug it into the enclosure via the front.Align it with fasteners and fix it on the tray.20) find the PCI of the motherboard-E slot, look at the back of the chassis where the slot is aligned with it.There should be a piece of metal that loosely blocks the holes that need to be highlighted on the graphics card port.Use a screwdriver or hammer, slam or pry the piece of metal and throw it away.Now, pick up your graphics card, lower the sides to the chassis with electrical contacts and align with PCIE slot.Make sure there is no interference and carefully guide the contacts into the slot and push hard until they are fully in place.The back plate should be highlighted from the holes you made, there is a small bracket on the graphics card, which should be aligned with the screw holes on the housing.As soon as you twist it, you are finished.21) similar to Step 20, install all other cards, such as sound cards, into the appropriate slots and secure each card with screws.22) at this point, you should physically install each major component into the chassis.All you have to do now is connect everything.23) find the 20/24-pin motherboard power connector and plug it into a socket that is usually located on one side of the motherboard.It only works in one way and hits when engaged.24) find the 4/8-pin CPU power connector and plug it into the socket, usually near the top of the motherboard, very close to the location of the CPU socket.Again, it only works in one way and will click in place.25) find the system fan or chassis fan connector and plug it into the socket on the motherboard.You must consult the motherboard manual to determine where it is.It is usually marked as a \"system fan\" or something like that.If you want to connect more system fans, you can look for a \"auxiliary fan\" connector on the motherboard or a molex cable using the power supply.26) positioning PCI-E.6/8 pin connectors and plugs, but many pin connectors and plugs are required to power the graphics card where applicable.Usually, in this case, the socket will face you at the edge of the card or at the end of the card.Click in place.27) find as many SATA power cables as you need to match SATA devices such as hard drives, DVDs, or optical drives.Container (as you can remember, it\'s thin, black and L-Shape) located on the back of the drive facing the back of the chassis.Push them forward with some force.They don\'t click like other cables until it seems to be in the seat all the time.28) find the same number of SATA data lines as in 27.They are similar to SATA power cords but are smaller.Plug them into the back of each drive next to the power outlet again.Now plug the other free ends of these cables into the motherboard where the SATA controller port is located.Please refer to the motherboard manual to determine where they are located.They are usually visible in color and look a bit like a USB port sticking out of a specific area of the motherboard.This part is tricky.Collect all the cables from the front of the chassis and you will notice the cables for power switches, reset switches, hard drive lights, power lights, etc.They can be combined into one connector or suspended separately.They may be marked as PWR and GND, or and-Or something else.Pressurized water reactor is one thing, GND and-are equivalent.Take a look at the motherboard manual to see where these pins are and which ones have which polarity.You have to use some judgment to match each pin in the chassis to the corresponding pin on its motherboard.If you make a mistake, the switch or light may or may not work, but I have never seen something catastrophic happen.Just swap the cable and try again.30) collect another bundle from the front of the chassis that handles all USB and sound ports.They may be united again, and they may not.Check the motherboard manual again and find the USB and sound pins for the front panel.Again, you have to follow the specific labeling scheme used by the motherboard manufacturer to determine which pin from the housing belongs to where.USB is usually 5 V, GND ,-, Corresponding to 2 power supplies and 2 data pins owned by all USBs.The sound pin has more mysterious tags that you have to match.The NC representative \"no contact\" means there is no need to go there.If you have HD audio instead of the AC97 standard, you have to connect the \"line output\" and \"microphone\" ports, and probably more.In order for your computer to run in any meaningful way, the minimum requirement is to install the operating system...Windows, for example.This is easy to do.1) pick up your Windows disc and put it in a DVD or Blu-ray drive.To open the tray, you need to start the computer.2) reset the computer and let it turn on.Typically, the BIOS will be configured to read any optical drive you insert.If not, hold down the delete key while the computer is up until the installation screen appears.Find something named \"boot order\" or something like that.Here you will see line items numbered in priority order.Make sure that the DVD drive is enabled at least once in this list so that the computer checks it.Save the settings, restart the machine and wait.3) the computer should read the disc and prompt you to load the operating system settings.Click the appropriate key to accept and let the computer load something.4) the installer will ask you if you want to install Windows.Follow the prompts and eventually ask if you want a typical installation or a custom one.If you don\'t care if your hard drive space is allocated, you can use the typical one.I like to set up my own drive so I always customize it but it\'s up to you.If you are as special as you are in setting up your drive, then you already
