Step 5: Finally, remove the graphics card from the slot, then connect one or two PCI Express power connectors to the graphics card. After that, restart your computer.

Check the power supply (PSU)

If the computer power supply (PSU) does not provide sufficient power to the graphics card, the device will not operate stably. This will cause the graphics card to not be recognized by the computer or the Windows operating system.

To check the power supply (PSU), you should follow these steps:

Step 1: Make sure the power switch on the power supply is not in the off position.

Step 2: Check if the power cable is securely plugged into the power socket and power supply. Try using a different cable and check the power socket to ensure they are not damaged.

Step 3: Check the internal connections of the computer, especially the power supply cables. Remove all components and hardware from the computer except the hard drive containing the operating system and the graphics card. If your computer has an integrated graphics card on the CPU, remove the dedicated graphics card from the computer as well.

Update the Windows system

If you encounter an issue where the graphics card is not recognized after updating the Windows operating system, it is likely that the recent update caused the problem. In this case, you can try uninstalling or reinstalling the Windows update to fix it.

To update the Windows system, you can follow these steps:

Step 1: Click on the “Start” icon on the Taskbar, then select “Settings”.

Step 2: Choose “Update & Security”.

Step 3: Select “Windows Update” and then click “Install now” to start updating Windows.

It is important to be patient during the update process. After completion, restart your computer and check if the graphics card is recognized in Windows.

Check the display ports (DVI, HDMI, VGA)

Display cables such as HDMI, DVI, and VGA may have errors and cause issues when the graphics card does not detect the monitor. You should check the display cables of the graphics card and ensure they are working properly.

To check the display cables, you can follow these steps:

Step 1: First, turn off the computer monitor by clicking the “Start” button on the Taskbar, then selecting “Power” and choosing “Shut down”.

After completing the above steps, restart the monitor and check if the graphics card has been successfully recognized.

Check if the graphics card is compatible with the motherboard

One of the common causes of graphics card errors is that your graphics card is not compatible with an old motherboard. In this case, you can try updating the BIOS to support the new graphics card. BIOS is the software that controls the hardware components of the computer, including the graphics card.

To update the BIOS, you need to download the latest BIOS version from the manufacturer’s motherboard website. After downloading, you should use a BIOS update tool to install the new version. This process is usually simple and easy to perform, but make sure to follow the instructions carefully to avoid any problems.

GPU BIOS is corrupted

In the event that the BIOS or GPU of the graphics card is corrupted, it will cause the graphics card to not be recognized correctly in the Windows operating system. One way to fix it is to set the graphics card to work at the VGA resolution using the default VGA drivers of Windows. Then, you can flash the BIOS of the graphics card or GPU using GPU flash tools.

Flashing the BIOS or GPU needs to be done carefully and according to the instructions provided by the graphics card manufacturer. This updates the firmware and settings of the graphics card to fix issues and optimize performance.
