What should I pay attention to when assembling a computer?

The installation process group should be divided into the following steps: 1. Options; 2. Check the attachment; 3. Light up the motherboard; 4. Put the accessories into the chassis; 5. Install the operating system. Let's take a closer look at the specific situation.

1. option. There is a lot of debate about choosing options, but it is not the focus of this article. If you don't know much about accessories, Bian Xiao suggests choosing products with good brand reputation and long warranty period.

2. Check the attachment. Generally speaking, when selling goods in Hao San Street, we will stick our company's warranty card on the accessories. Everyone should pay attention to whether the accessories are brand-new before sticking the warranty card. There are many opinions about inspection. Bian Xiao suggested that the trauma and use marks of each accessory should be carefully checked. (1) It is very important to check whether the CPU is packaged in the original factory, whether there are any grinding marks, and whether there are any broken or crooked feet. (2) Whether the memory stick has polished marks, whether the gold finger of the memory stick is seriously scratched, and whether the gold finger is skewed. (3) whether the seal of the main board is in good condition and whether the board base is in good condition. (4) The graphics card inspection is similar to the memory card. (5) Hard disk inspection is similar to that of CPU, with emphasis on inspection for damage and scratches. (6) Whether the optical drive is in good condition, with or without scratches and clean. (7) Check whether the monitor is clean and scratched, and pay special attention to check whether the monitor has been disassembled. Only the accessories are basically free of trauma or obvious traces of use can they be installed, otherwise many parts may be damaged. On the other hand, the inspection is to ensure that the accessories are brand new, and to prevent JS from passing the buck if something goes wrong.

3. Light up the motherboard. Although it is said to light up the motherboard, it is actually a simple check to see if the system can run. First, insert the CPU into the CPU slot on the motherboard. It should be noted here that you should never use brute force. The CPU has a missing corner. As long as the missing corner on the motherboard is correct, the CPU can be gently inserted into the motherboard. If it is found that it cannot be easily inserted, it is recommended to check the installation again until it can be easily inserted. After the CPU is inserted, you can press the lever until the lever is close to the motherboard. Next, install the CPU fan. Generally, fans are stuck with silicone, and a thin layer of silicone can be coated on the bottom of the fan. Pay special attention to the installation of fans, especially those CPU without metal cap. It is best to fix the fan clips on both sides of the CPU slot in different directions. Then plug the power cord of the fan into the three-pin power connector near the CPU slot. At this point, the CPU installation has been successfully completed. Second, insert the memory stick. The memory card interface is designed asymmetrically, so it can be inserted smoothly as long as it is aligned with the gap. After insertion, gently press the memory stick, and the button of the memory stick on the motherboard will automatically clamp the memory stick. The memory module has been successfully installed here. Next is the installation of the graphics card. The graphics card interface is also asymmetrical and can be easily inserted. Let's remind you not to forget that some graphics cards need an external power supply. Similarly, many motherboards have buttons on AGP slots. After the graphics card is installed correctly, it will be firmly stuck by the motherboard card. Of course, when unplugging the graphics card, you should be careful not to break the graphics card! Then plug the interface of the monitor into the graphics card. Next, you need to connect the power supply to the motherboard. As you have noticed, the wide and long slot on the motherboard, usually white, is used to connect the power supply. Similarly, this interface is designed with an inverted hook, so it can't be plugged in if it is installed backwards. This is the only interface on the motherboard where power can be installed. Then plug the four-hole power interface into the only corresponding interface on the motherboard. At this point, the connection of power supply is basically completed. Next, find the power jumper (generally, this jumper is designed at the edge of the motherboard. Unfamiliar friends can check the motherboard manual, which is actually very easy to find. Generally, the motherboard is marked with PWR SW near the jumper), and then connect the two jumper posts with a screwdriver or key to light the motherboard. After lighting, the system will display the information of the graphics card first, and then the BIOS will display the information of the motherboard, CPU and memory. You can compare whether the BIOS display information is the same as your own configuration. If differences are found, it is recommended to consult the jumper settings in the motherboard manual and make changes.

After confirming that the information in the BIOS is the same as your own configuration, you can install all accessories into the chassis. Short-circuit the jumper mentioned above again, and the motherboard will lose power. Carefully unplug the video card and power cord. There is no need to remove CPU, fan and memory at this time. Add 4. Install the accessories into the chassis. First, put the CD-ROM drive and hard disk into the chassis. The installation of optical drive sometimes needs to remove the metal baffle and plastic baffle in front of the chassis, and sometimes it doesn't need to be removed, depending on how the chassis is designed. Generally speaking, it is necessary to remove the front cover of the CD-ROM tray without removing the plastic bezel. Removing this thing requires power supply to the optical drive to eject the tray, and it is generally laborious. It is suggested that friends with less experience should not disassemble this Dongdong, in case something goes wrong, there will be no guarantee. Insert the optical drive into the chassis from the front of the chassis and tighten the screws on both sides. The installation of the hard disk is relatively simple, but Bian Xiao suggested setting the jumper of the hard disk before installation. Generally speaking, it is better for the hard disk to jump to the main disk. After the jumper is set, put the hard disk into the 3.5-inch rack of the chassis and tighten the four screws on both sides. If you need to install a floppy drive, you can refer to the installation method of the CD-ROM drive.
