Method/Steps

1. So assemble a large collection of computer accessories (unopened)

2. Assembly step one: At this time, first open the motherboard CPU card slot. There are two alignment holes on the CPU and the motherboard. After aligning, gently put the CPU into the card slot. Make sure it is flat and then buckle the motherboard CPU card slot, so that the CPU The installation is complete, this is very simple

3. Assembly step 2: The CPU has been installed into the motherboard above, now you can install the CPU fan. (Be careful not to reverse the air inlet and outlet directions of the front and rear doors during installation)

4. Assembly step 3: Take out the memory module. The gold finger under the memory module is partially free. This is to prevent reverse insertion. design. As long as the socket is aligned and pressed down, the buckles on both sides will automatically return to their original positions. Check whether the buckles are tightened. If they are, the memory module is installed.

1. When purchasing, be sure to match the memory module to the memory standard supported by the motherboard. DDR3 motherboards can only use DDR3. Be sure not to buy the wrong one, otherwise you will not be able to plug it in when you come back; 2 .When using multiple memory modules, multi-channel issues will be involved. On the INTEL platform, the method of inserting one memory module every other can enable the multi-channel to be opened normally; on the AMD motherboard, two memory modules need to be inserted adjacently, but not in the middle, but on the two left or two memory modules. The two on the right. 3. Some CPU radiators will block the memory slot closest to the CPU, making it impossible to insert some larger memory modules. If you don't need that slot, change it to another slot. If you need to use that You can only replace the narrow memory.

After installing the motherboard, CPU, and memory modules, we can put the motherboard aside first. The next step is to install the power supply of the main chassis. If the motherboard is installed on the chassis first and then the power supply is installed, it will be more troublesome. .

5. Assembly step 4: Install the inlet and outlet fans in the main chassis. Some mainframes need to be completely disassembled before the fan can be easily installed. This depends on the situation of each mainframe.

6. Assembly step 5: When installing the power supply, it can be divided into modular power supply and non-modular power supply (there is also a semi-modular power supply) according to the outlet type. The so-called module and non-module power supply are different in the power output line. The non-modular power supply has all the wiring provided by the power supply laid out and cannot be disassembled. The module power supply arranges the wiring provided by the power supply on the back of the power supply in the form of interfaces, and then provides module cables (some power supplies need to be purchased separately). Each module cable is connected to a different power supply interface. The module power supply can be connected to whatever is used, the wiring is beautiful, and the chassis is tidy. The semi-modular power supply is partially wired for direct output and partially provides a module interface.

7. Assembly step 6: Now you can install the hard disk into the chassis. The location of the hard disk varies in different chassis. This depends on the specific situation.

8. Assembly step seven: After installing the hard disk, you can now install and fix the motherboard with the installed CPU and cooling fan into the chassis. Note that you install the backplane from inside the chassis, and be careful not to put it upside down. This thing does not have an anti-reverse design. After installing the backplane, you can put the motherboard on it. The location of the motherboard is obvious. The location of the backplane on the chassis coincides with the location of the backplane interface on the motherboard. Based on this idea, the motherboard can be quickly located.

When the positions are almost the same, there are corresponding holes on the motherboard, and these two need to correspond accurately. After that, take out the round head screws, put them one by one into the aligned holes, and tighten them with a screwdriver. The motherboard is now fixed.

9. Assembly step 8: After installing the motherboard, you can proceed with the internal wiring of the chassis and the back wiring. This is also my first time wiring and back wiring. All refer to Baidu video tutorials, and then refer to the wiring part. According to the motherboard manual, generally all the wiring sockets are corresponding, and it is unlikely to connect the wrong socket. Pay special attention to the power indicator light, power switch, reset button and other sockets on the chassis. These sockets are relatively small. Do not connect them incorrectly, otherwise you will have to I picked it up again, just be careful about this. My hard drive is a SSD solid state 1T mechanical hard drive. To achieve full performance, the SSD solid state data cable must be connected to the SATA3 interface. If it is connected to the SATA2 interface, it can be used, but the performance cannot be fully exerted. The mechanical hard drive can use SATA2 or SATA3 interfaces without any problem.

10. Assembly step 9: The last step is to install the graphics card. The graphics card is relatively large, so I put the graphics card where it is best to install it to facilitate wiring and routing at the front. The installation of the graphics card is very simple. First check the position of the PCI-E interface, then remove the metal card strip shield on the rear of the chassis, insert the graphics card into the PCI-E, and install the screws. The Gigabyte GTX970 G1 graphics card is powered by 8 6. The power socket cord is reserved, so that the installation of the host is basically completed. Connect the monitor and turn it on to see if the host can light up. If it does, it means there is no problem with the installation.

The following pictures show the back wiring and wiring I took, and the pictures of the main unit that are lit up. The back wiring is not very good, so please don’t complain if you are a DIY computer veteran.

11. Next, let me talk about the solution to troubleshoot the machine not lighting up: 1. Confirm that the power cord has been connected and the switch outside the power supply has been turned to the "-" position. 2. Confirm that the 20 4PIN cable connecting the power supply to the motherboard is completely connected. 3. Confirm whether the connection cable between the front panel and the motherboard is plugged into the correct position, especially the 'POWER SW' connection. If it is connected incorrectly, it will be useless if you press the power button. The machine that does not light up here means that there are no signs of power on, including the CPU fan rotating, the mechanical hard drive rotating, the power supply fan rotating, and the monitor having a signal. If there is a phenomenon here, it means that the entire machine is indeed powered on.

12. If there is only no signal on the monitor, you should follow the following steps to eliminate it: 1. Turn on the monitor power, install the monitor cable firmly, and the monitor is turned on; 2. If you use the DVI-VGA interface, you need to pay attention to its use. Is the DVI port DVI-I? If not, you cannot use the adapter, and the adapter is invalid; (my monitor does not have DP and HDMI interfaces) 3. If you have an independent graphics card, please do not connect the monitor to the motherboard. On the display interface, even if you want to use some software to switch between the integrated display and the independent display, you must first connect it to the independent display, because some motherboards preferentially output video signals on the independent display when detecting the independent display, but the integrated display does not output a signal. Naturally, it is impossible for the monitor to have a signal; 4. Check whether the golden finger of the graphics card is completely inserted into the PCI-E 16X slot; 5. There is still no signal. If the motherboard provides display output or the CPU has a core display, unplug the independent graphics card. , use the integrated display and try again. If there is signal, it means there is a problem with the graphics card or the slot.
