Gpu Isn’t Showing Up When Plugged In – A Comprehensive Troubleshooting Guide!
If your GPU isn’t detected, ensure it’s properly seated, power cables are connected, and drivers are updated. Test the GPU in another system if needed.
In this article, we will walk you through the most common causes of a GPU not showing up when plugged in and provide you with solutions that can help you get your system running smoothly again.
What is a GPU and Why Is It Important?
Before diving into the solutions, let’s first understand what a GPU is and its role in your computer.A GPU, or graphics card, is a hardware component in your computer responsible for rendering images, videos, and animations. It is especially important for tasks like gaming, video editing, 3D modeling, and anything that requires high-quality graphics. GPUs are essential for delivering smooth and high-performance graphics in modern computing.
Common Reasons Why a GPU May Not Show Up:
Improper Power Supply Connections:
One of the most common causes for a GPU not showing up is improper power connections. Modern GPUs require more power than the motherboard can provide through the PCIe slot alone. As a result, many GPUs come with dedicated power connectors, typically 6-pin or 8-pin PCIe cables, that need to be plugged into both the GPU and the power supply unit (PSU).
Solution:
- Check Power Cables: Ensure that all power cables are correctly plugged into the GPU. Double-check the 6-pin or 8-pin power cables from the PSU to make sure they’re securely connected to the GPU.
- Confirm PSU Capacity: If you recently upgraded your GPU, ensure that your PSU has enough wattage to support it. Some high-performance GPUs require a powerful PSU, often in the range of 600W to 1000W or more.
Faulty or Improper Installation:
Sometimes, the issue can be as simple as the GPU not being properly seated in the PCIe slot. If the GPU is not fully inserted, the motherboard may not detect it.
Solution:
- Reinstall the GPU: Turn off your PC, unplug it from the power source, and carefully remove the GPU from the PCIe slot. Then, reinsert the GPU, ensuring that it’s securely and fully seated. Make sure that the PCIe latch clicks into place to hold the card.
- Test Another PCIe Slot: If the GPU still isn’t detected, try inserting the GPU into a different PCIe slot on the motherboard. Sometimes, a particular slot can be faulty or incompatible with certain GPUs.
Driver Issues or Outdated Drivers:
If the hardware is correctly installed and receiving power, but the GPU still doesn’t show up in the device manager or detection software, the issue might be with the drivers. A missing or outdated driver could prevent the operating system from recognizing the GPU.
Solution:
- Reinstall Drivers: Visit the official website of your GPU manufacturer (NVIDIA, AMD, etc.) and download the latest drivers. You can also use automatic tools like NVIDIA GeForce Experience or AMD Radeon Software to ensure you’re using the correct version.
Uninstall any existing GPU drivers via the Device Manager (right-click Start > Device Manager > Display Adapters), then reboot your PC and install the latest drivers.
- Use Display Driver Uninstaller (DDU): If you encounter driver conflicts, use DDU, a tool that completely removes old drivers. After running DDU, reinstall the latest GPU drivers.

BIOS/UEFI Settings:
The system BIOS/UEFI firmware plays a crucial role in detecting hardware. If the settings aren’t configured correctly, the GPU may not be recognized during boot-up.
Solution:
- Enter BIOS/UEFI: Restart your computer and press the appropriate key (usually Del, F2, or F10) to enter BIOS/UEFI settings.
- Check Primary Display Settings: In the BIOS/UEFI menu, ensure that the primary display adapter is set to PCIe (or similar) and not integrated graphics.
- Reset BIOS Settings: If you’ve recently made changes to BIOS/UEFI settings, consider resetting them to default to rule out any configuration errors.
Faulty GPU or Hardware Malfunction:
If your GPU is not detected, the issue could be a faulty GPU or motherboard. This is particularly likely if the GPU was working previously but suddenly stopped showing up.
Solution:
- Test the GPU in Another System: To confirm whether the GPU itself is faulty, try plugging the GPU into another computer. If it still doesn’t work, the issue is likely with the GPU.
- Test Another GPU in Your System: If you have access to another GPU, insert it into your computer. If this new GPU works, then the issue likely lies with the original GPU.
PSU Compatibility and Power Issues:
If the power supply is underpowered or incompatible with the GPU, it may not be able to supply the necessary voltage for the GPU to function properly.
Solution:
- Ensure Sufficient Wattage: Check the wattage rating of your PSU and make sure it meets the requirements of your GPU. High-performance GPUs, especially those in the RTX 30 series or similar, require more power than entry-level GPUs.
- Test a Different PSU: If possible, test your GPU with a different, known-good PSU to ensure that power delivery is not the issue.
Operating System Issues:
Occasionally, software or operating system-related issues can prevent the GPU from showing up. This could involve corrupted system files or conflicts between other hardware and the GPU.
Solution:
- Check for OS Updates: Make sure your operating system is up to date. Sometimes, a newer version of Windows (or Linux) will include compatibility fixes for newer GPUs.
- Perform a System Scan: Run the Windows System File Checker tool (sfc /scannow) to check for and repair corrupted system files that could affect device detection.
External Display or Cable Problems:
It’s possible that the issue isn’t with the GPU itself but with the display or the cables you’re using to connect to the GPU.
Solution:
- Check the Cable and Monitor: Ensure the monitor and display cables are functioning correctly. Try using a different cable (HDMI, DisplayPort, etc.) and ensure the monitor is set to the correct input source.
- Test the GPU with Another Monitor: If you have a second monitor, connect the GPU to that to rule out display-related issues.

Why is my GPU not being detected?
If your GPU is not being detected, there could be several reasons. First, check if the GPU is properly seated in the PCIe slot. Ensure the power connectors are securely plugged in. Next, update or reinstall your graphics drivers, as outdated or missing drivers can cause detection issues. Also, make sure your motherboard’s BIOS is up to date. If the GPU still isn’t detected, it might be a hardware issue, and you may need to test the GPU in another system.
Why is my GPU not detected by my PSU?
If your GPU isn’t detected by your PSU, there could be several causes. First, check if the power cables from the PSU are securely connected to the GPU. Ensure the PSU is providing enough wattage for your entire system. If the PSU doesn’t have the correct connectors, like 6-pin or 8-pin, it won’t supply enough power. Also, check that the PSU is turned on and functioning correctly. If everything seems fine, test the GPU in another system to rule out hardware issues.
