Method 6: Check power supply to Fix the graphics card not detected error

If you’re testing the graphics card for the first time and are confident that it’s working properly, the problem could be with your power supply. The graphics card frequently requires more power than the power supply can deliver. Even though your graphics card appears to be operational, this does not imply that your power source provides adequate power to it.

We can’t tell you how powerful a power supply you’ll need because it depends on your graphics card and power supply. Some graphics cards demand greater processing power than others. Check your power supply’s power ratings and how much power your graphics card requires. If your power supply satisfies the minimum criteria, you will need to purchase a new one. Ensure that your power supply has a significant amount of extra wattage than your graphics card requires.

Also, ensure your graphics card is powered up and linked to the power supply. The fans on your graphics card are spinning doesn’t mean the power cables are correctly connected. This problem could be caused by a graphic card that is only partially powered.

Method 7 – Install the Graphics Card Properly

Are you installing the graphics card for the first time? If yes, here are a few things that you need to confirm.

• Ensure your graphics card is safely seated in the PCIe slots. You will find these slots on the motherboard.
• Make sure the power connectors to the graphics card are securely and correctly connected.
• Your PC monitor should be connected to the GPU, not to the motherboard.
• If you find that the PCIe slot contains dust, you should clean it with a soft cotton cloth.
• Some users have resolved similar issues by switching to the PCIe slot. Therefore, consider trying that, too.

If you have installed the graphics card properly and the issue persists, unplug it and reconnect it. It might help you resolve any temporary issue that affects the detection of the graphics card.

Method 8 – Make Sure Your Graphics Card is not Faulty.

If you have tried all the above-mentioned solutions and none of them has resolved the issue, the real problem might lie with your graphics card. When you hear strange fan noise, graphics-related errors, frequent PC crashes and blue screen of death, and the unexpected decline in gaming performance, these are all the signs of a malfunctioning graphics card.

Method 9 – Test the Card in Another PC

This is the final, definitive test. If you can, put your graphics card into a friend’s computer.

• If it works in their PC: The problem is with your motherboard, PSU, or software.
• If it does NOT work in their PC: The graphics card itself is very likely faulty and you should contact the manufacturer or retailer for a warranty replacement (RMA).
