The computer screen does not light up after replacing the graphics card

The computer has a new graphics card. The graphics card lights up and the fan spins, but the monitor shows no signal. When I replace it with the old graphics card...

1. The monitor has a black screen. Faults are relatively common, often manifesting as no image display on the monitor after the computer is turned on, but a "beep" sound is heard when the host starts normally; or the monitor suddenly goes black when it is being used; sometimes the computer starts normally, but when the computer starts up to a certain step A black screen appears.

2. Troubleshooting method: First check whether the replaced graphics card model is compatible. For example, if the old graphics card is ATI, but the graphics card is replaced by an NVDIA graphics card, this will definitely not work. The old graphics card driver is still on the computer, and it will definitely not work if the new graphics card is not compatible with the old one.

3.: First of all, generally speaking, the monitor shows no signal because the monitor’s data cable has fallen off. Make sure the connection is normal. 2: If the monitor shows no signal, it may be that the monitor’s data cable is broken and the data cable needs to be replaced.

4. Check whether the motherboard's graphics card socket matches the socket of your new graphics card. Whether the motherboard socket is divided into AGP and PCI-E.

5. Independent graphics card. If it is a dual graphics card, it should be connected to the PCIE interface closest to the CPU.

6. Computer host failure (1) Failure caused by host power supply. Black screen failure caused by damage to the host power supply or poor quality of the host power supply is very common.

The screen does not light up when the integrated graphics is replaced by independent graphics

The independent graphics card has insufficient power supply. Because the output power of the power supply is too low and there is no independent power supply interface, the independent graphics card has insufficient power supply and cannot light up. You need to check whether the 6PIN or 8PIN power supply interface of the independent graphics card is plugged in properly. Bad contact with the graphics card.

If the monitor does not have power (the indicator light does not light up), look at the back of the monitor, plug the power cord plug connected to the monitor upwards, and check whether there is power from the other end of the power cord to the socket.

You can refer to the following methods and try them one by one: If there is a BIOS setting problem, you can stop using the integrated graphics card on the motherboard in the BIOS. Different motherboards have different stopping methods. For details, please check the motherboard manual. Jumper issue.

Why the monitor does not light up after installing the graphics card

Check whether the graphics card has an independent power supply and whether the power supply is connected properly.

3. The main reasons why the black screen does not light up after the graphics card driver is installed are as follows: The driver version is incompatible. The latest driver version may be incompatible with the system or current hardware, causing a black screen. You can try to download an older compatible driver and install it. System files are corrupted.

4. If the above does not solve the problem, consider that the independent graphics card is not compatible with the motherboard. You can go to the motherboard's official website to see which types of graphics cards the motherboard can support, and then change the graphics card according to the model. Finally, the signal wiring needs to be checked. The monitor side and the independent graphics card side must have the same type of interface at both ends.

5. Check whether the graphics card is fully inserted into the PCI slot of the motherboard; check whether the power interface is connected and whether the light can be lit; re-plug the signal output from the monitor and graphics card or replace the wire; check the power supply to see if the power consumption of the power supply is sufficient.

6. Reason: The graphics card is installed incorrectly, causing the motherboard to be unable to recognize the graphics card, causing the monitor to not display. In this case, you need to remove the graphics card and reinstall it according to the installation instructions in the manual. The monitor's cable is still plugged into the motherboard, not the discrete graphics card.

Solutions to why the monitor does not light up after replacing the graphics card on your computer
