Sometimes after GPU installation, the power cables may be not connected to the screen correctly. This wrong wiring issue may cause a black screen. You must check and ensure the power cables attached to your monitor screen are correctly connected.

In some situations, the power cables between the graphics card and the screen are also attached wrongly. Due to this reason, the users also get no display from GPU or motherboard because the graphics card has no access to the screen.

To solve the no-display issue on the screen, you need to unplug all cables from GPU and motherboard. Then fix these cables correctly to solve the black screen issue. If the issue is the same as earlier, use a new cable to check the cable issue. Check the display screen with another PC to make sure the issue is on screen or not.

Another issue that can cause your screen to not display is that your graphics card is not getting proper power from the motherboard. Some high-performance graphics cards need more power to work and do not work if they have an insufficient power supply. Make sure the sufficient power supply to your new graphics card after installation.

Graphics cards have two types of power supply pins; six-pin connectors and eight-pin connectors. If the power connector pins on the motherboards are not enough, you can attach an extra two-pin power connector.

Check the PCI Slots on Motherboard

Check the PCI Slots on Motherboard

One main reason for no display on the screen is that you have not connected the graphics card to the correct motherboard PCI slot. Motherboard has many slots to install the graphics card and you need to process the installation on the correct slot. Remove all the power cables and open the motherboard case to fix this issue.

Check the slot on it and make sure the GPU is installed on the proper slot to get the right output. If the slot is not in working condition, you can change the slot for GPU installation.

Reinstall or Update the Graphics Card Drivers

Reinstall or Update the Graphics Card Drivers

If you have installed a new graphics card, it may require driver updation to work efficiently. You will receive an automatic update notification after installing the graphics card. If you do not install the new drivers, the graphics card will work for some time and then may cause issues such as no display on the screen.

Reinstall the graphics card drivers to make the functionality proper on the display screen. Uninstall the drivers on your system and then reinstall them to get proper output. Check for drivers and update these drivers on your system to get a proper output screen. 

  • You can also check for driver updates by going to the control panel.
  •  Open the device manager and click on the display adaptor.
  • Here click on GPU and then on the driver option to know about the driver details.
  • In the detailed screen, you will get all information about GPU drivers with the “Update Driver” option.
  • Click on “Update Driver” to run the driver updation process and fix the graphics card with no display issue.

Driver reinstallation and updation will fix the installed new GPU no display issue.

Check the External Devices on Motherboard

Check the External Devices on Motherboard

In some situations, the external devices attached to the motherboard cause issues and interfere with the display screen. If it is happening, you need to check and fix the issue by troubleshooting it. Unplug the system from all the display-connected devices. These devices may include a mouse, USB, card reader, or other devices connected to the motherboard.

Here you also have to disconnect the internet connection and speakers. Now connect the GPU and motherboard only with the display screen to check the issue is not created by an external device. If the screen is still black, it means there is an issue with the graphics card.

Check GPU and make it Dust Free

If the external components on the motherboard are dusty, they do not give proper output. The same issue may happen with the graphics card if it has dust it will not show efficient output on the screen. So the issue is not as serious as it is shown sometimes. You must check that all the external components are dust-free and get a proper power supply.

Open the case and clean all components connected to the motherboard including the graphics card. Also, clean the PCI slot to which you have installed the graphics card.

Check Out CPU and GPU Power

Check Out CPU and GPU Power

CPU power matters much in the proper functioning of graphics cards on the system and motherboard. If you are facing an irregularity in GPU functioning, it means that your CPU has an insufficient power supply. The GPU needs the power to work that it gets from the CPU and then performs its duty to provide the best screen display. If there is such a CPU power issue, it will also affect the GPU power.

Check your power supply unit (PSU) or ask the manufacturer to check if you are finding a black screen after installing a new GPU. if the CPU is running underpower, you must solve this issue by replacing the PSU with a new one. It will solve the issue if it is happening to power.

Wrapping Up

If you installed new GPU but no display is on screen, it may be the result of the issues stated above. Check the problem and fix it to get a high-rated screen instead of a black display on it. Check the power supply, power cables, internal components, and PSI slots to solve the new GPU no display issue. If the issue is not solved by checking out all other connections then there will be an issue with the graphics card.
