The screen of your newly assembled computer often goes black but then returns to normal, which is a headache. This is a common problem and can have several causes. PHP editor Xiaoxin will analyze it one by one for everyone to help you solve this problem. The following content will introduce the possible causes and corresponding solutions in detail for your reference.
The graphics card driver is incorrect (the graphics card comes with its own CD). Motherboard problems or graphics card problems (mostly motherboard problems, I have encountered similar problems before) Solution: Replace it immediately where it is installed! Also, this power supply is a bit weak!
You mean, are you sure the machine is running, but the screen is not showing?
First of all, make sure your screen is black when there is no signal or it will prompt no signal or other symptoms. If it is also black when there is no signal, you may need to check the contact of the video cable.
If the screen does not go black when there is no signal, like when you turn on the computer, you may have to check for a contact problem with your graphics card or even a problem with the graphics card itself.
There is another possibility. If you use a converter like VGA to HDMI, the problem is likely to occur in the converter, because I have encountered similar problems.

Assembling a computer does require a checklist, because when we assemble the computer, after determining the configuration and operation requirements of the computer, we can purchase some suitable motherboards online, and then determine the power supply, graphics card and other configurations based on the motherboard. If you ask, just make a list and ask the computer factory or dealer directly to buy it
Assembling a computer can have some benefits, such as:
1. Customized configuration: Assembling a computer can choose the appropriate hardware configuration according to personal needs, and you can choose more based on your own purpose and budget. Suitable components.
2. Cost-effectiveness: Assembling a computer is more cost-effective than purchasing a brand-name machine. You can save costs by choosing hardware with higher cost-effectiveness.
3. Upgradeability: Assembling a computer is usually easier to upgrade the hardware. The hardware can be upgraded or replaced at any time as needed to improve the performance of the computer.
4. High degree of freedom: When assembling a computer, you can choose the appearance design, color matching, etc. according to your personal preferences, and you can create a unique computer.
However, there are also some challenges and risks in assembling a computer, such as requiring certain professional knowledge and skills, choosing inappropriate hardware that may cause compatibility issues or poor performance, possible risks during the assembly process, etc. . Therefore, if you do not have enough experience and skills, or do not know much about computer hardware, it may be more suitable to buy a branded machine.
There are drawings when you buy a computer desk, just assemble it according to the drawings
1. First connect the VGA cable to the monitor, and then fix the two screws at the back. The main reason for fixing is to worry about the connecting wire falling off when moving.
2. Then connect the other end of the VGA cable to the computer host.
3. Next, connect the power cord to the monitor. (Note that you only want to connect it to the monitor. Do not connect the other end of the power cord to the socket. Wait until all connections are completed before turning on the power.)
4. Next, connect the mouse to the host.
5. Connect the keyboard as well. (The green one is the mouse, and the purple one is the keyboard. Also note that the internal pins of the mouse and keyboard plugs must be aligned with the pinholes in the interface before they can be inserted.) Connect one end of the network cable to the RJ45 interface of the computer host, and then connect the other end to the switch or router or modem.
6. Next, connect the power cord of the host.
7. Next, you can connect the power plugs of the host and monitor to the sockets to power on the host and monitor. You can start and use it normally.

This should be caused by a poor quality screen. It may be that the screen cable is not in good contact. It is recommended to reinstall or replace the screen.
1. First check whether the VGA video cable is firmly inserted into the host interface and monitor interface, then check whether the contact between the graphics card and the motherboard I/O slot is good, and finally check whether the CPU fan is operating normally;
2. If the computer starts normally after changing the display, the original display may be damaged;
3. You can remove all components of the computer except the CPU, graphics card, and memory module and then turn it on. If the memory is faulty, there should be an alarm sound. If there is no alarm sound, replace the CPU and start the computer again to test again. If the computer still has a black screen, it is recommended to replace the motherboard;
4. If the system installs software and updates patches and causes a black screen, try uninstalling the update files;
5. Restart the computer after installing the software. The update is causing a black screen and wait for the update to be completed.
6. Enter safe mode to repair the computer. If you cannot enter safe mode, please reinstall the system.
