How to assemble and turn on the computer?

When assembling a computer, the first step is to select the motherboard, CPU, and memory. harddisk. graphics card. chassis and power supply.

The second keyboard, mouse, monitor, camera and other peripherals.

The third part is assembled. Insert the cpu, hard drive, and graphics card. Power supply, etc. are connected as required. The keyboard, mouse, and monitor peripherals are connected to the corresponding interfaces.

The fourth step is to choose a windows system or a linux system when making a system disk. The fifth step is to install the system.

The sixth part starts.

How to plug in the power cord when assembling a computer?

1. Take out the motherboard, remove the CPU and install it, fix the fan, plug in the memory and put it away.

2. Remove the covers on both sides of the chassis, install the power supply, and screw the motherboard tray screws in the chassis to the designated position.

3. Handle the motherboard baffle according to the interface position, snap it into the chassis back bezel, put the motherboard correctly into the chassis, and gently tighten the screws. For independent graphics, break off the small PCI-E baffle, insert the graphics card and secure it with screws.

4. Plug in the 24+4-pin power cord. If the 4-pin cord is too long, tie it into a knot.

5. Separate the front USB and audio jack cables with USB and AUDIO letters on the back from the chassis, and insert them into the USB pin slot and AUDIO pin slot of the motherboard respectively. Both are to prevent mis-insertion. The USB pin slot is usually in the lower right corner of the motherboard, and there is a USB mark under the pin slot. The AUDIO pin slot is generally located in the middle and lower left side of the motherboard.

6. Knot the switch, restart, hard disk indicator light and other wires on the chassis. Generally, this type of plug on the motherboard is adjacent to the USB. In the lower right corner of the motherboard, there are letters indicating the corresponding plugs, such as HDLED. is the hard disk indicator light, RST is the cold start, POW-SW is the startup, SPEAKER is the alarm horn, and POW-LED is the power indicator light. Just plug them in one by one.

7. Remove the baffle at the optical drive position of the chassis (the card head can be pushed out from the back and removed). Put the optical drive in and secure it with screws.

8. Take out the optical drive and hard disk data cable. If it is a parallel port data cable, please confirm that there is an IDE interface on the motherboard. The serial port cable is generally longer. After forming a spiral shape with your fingers, you can insert it into the motherboard serial port port in sequence, and then plug in the optical drive and hard disk power cables.

9. Use tying thread to gather and fix the messy threads appropriately. Install the side covers in sequence. You're done, the next step is to partition the hard drive and create a system.

Purely personal experience, let’s discuss the shortcomings together. Reproduction is prohibited.

If the computer can be turned on after assembling it, it proves that the computer is not wired incorrectly, right?

First of all, your power supply is connected correctly, but this alone cannot determine whether your jumper wires are connected correctly, and whether the fan is connected in the opposite direction and blowing inward (tower fan)

No How to turn on the assembled computer?

If there is no chassis: Find the double row of bare pins from the motherboard (usually including PWR_LED, RST, HDD_LED, PWR, etc., meaning: power indicator light, restart, hard disk indicator light, power supply) . Just short-circuit the two pins of the power supply (connect them with a conductor). If a tractor card is used: the host power must be turned on

How to assemble and start a desktop computer?

Assemble a desktop computer and reinstall the system:

1. Make a USB flash drive, then go to the relevant website to download the win system and save it to the USB boot disk, restart the computer and wait for the boot screen to appear and press Start Shortcut key, select u disk boot to enter the u boot main menu, select the "u boot WIN8PE standard version (new machine)" option, press the Enter key to confirm

2. Select the win image in the pe installation tool Place it in the c drive and click OK

3. At this time, click the "OK" button directly in the pop-up prompt window

4. Then the installation tool starts to work, we need to wait patiently for a few minutes

5. After completion, a pop-up prompt box will prompt whether to restart immediately. At this time, we can just click Restart Now.

6. At this time, you can remove the USB disk and restart the system to start the installation. We do not need to perform any operations, just wait for the installation to complete.

How to turn on the computer after assembling it yourself?

After the computer is assembled, make sure that all the internal power cords are connected in place. After confirmation, connect the power supply and start the computer directly.

There is no need for you to do anything. Once the computer starts up normally, it means that the computer has been successfully assembled.

Then enter the system and see if it can operate normally. It is best if it can continue to run for a period of time. If it does not malfunction, it means that your computer is installed well.

What are the correct steps to assemble and turn on a computer?

The steps for booting the computer into the system for the first time after it is assembled are as follows.

1. Directly select the startup item. After booting, immediately press F12, or use the Fn and F12 keys to enter the quick startup options interface.

2. Enter the startup item selection interface. There are startup items for hard disk, CD, and U disk. Select the name of the device and press Enter. You can use the device to start the computer. To learn the name of the startup device, you can go to You will know in the device manager.

3. Check the motherboard manual. After purchasing a computer or motherboard, there will be a manual that will introduce how to enter the system.

How to insert the power button on the assembled computer?

Step 1: Preparation

Before installing the computer power-on key, you need to prepare the following tools and materials:

1. Computer power-on key

2. Screwdriver

3. Wire pliers

4. Wire sleeve

5. Wire

Step 2: Open the computer case

First, you need to open the computer case. Use a screwdriver to remove the screws from the case and open the sides of the case.

Step 3: Find the power button socket

After opening the case, you need to find the power button socket. It's usually located on the motherboard, and you can check the motherboard's manual to determine its location.

Step 4: Connect the wire

Insert the wire into the power button socket. Then, use wire cutters to secure the wire to the outlet. To protect your wires, you can put wire sleeves on them.

Step 5: Install the power button

After the installation is complete, you need to test whether the power-on button is working properly. Press the power button and see if the computer starts normally. If the computer won't start, you need to check that the connections are correct.

Step 7: Close the chassis

After the test is completed, you need to close the chassis. Use a screwdriver to tighten the screws on the case and make sure the case is securely closed.

How to plug in the computer assembly?

1. First insert the 24PIN in the power supply into the 24PIN slot of the motherboard. This item is the mainboard power supply line: after the motherboard power supply connection number.

2. Then there is the CPU power supply. Look at the motherboard. If it is 8PIN, just combine it and insert it. Generally, the CPU power supply is 4PIN. Insert the 4PIN interface in the power supply into the 4PIN slot near the CPU.

3. Then pay attention to whether your graphics card has a 4PIN interface. Generally, low-end graphics cards do not have it.

What wires are needed to assemble a computer?

Too much.

First, two power cords are needed. One is to understand the socket and the host, and the other is to understand the socket and the monitor.

Second, the data cable connects the monitor and the host.

Third, the color difference cable connects the sound card and speakers.

Fourth, the microphone cable connects the sound card and microphone.

Fifth, the hard drive cable connects the hard drive to the motherboard.

Sixth, the drive cable connects the optical drive to the motherboard.

Seventh, expansion device cables, some are connected to the motherboard, and some are connected to the sound card

Eighth, USB cable, this is very common now.
