Troubleshooting GPU Recognition Issues on HP M01-F1024 Desktop with XFX Radeon RX 580

Are you experiencing difficulties getting your new graphics card to be recognized by your HP M01-F1024 desktop? If so, you’re not alone. Many users encounter challenges when upgrading their graphics hardware, especially on pre-built systems with specific hardware configurations. This guide aims to help you systematically troubleshoot and resolve issues related to your XFX Radeon RX 580 not posting or appearing in Device Manager.

Understanding the Situation
In this scenario, the user has upgraded their daughter’s HP M01-F1024 desktop with an XFX Radeon RX 580 graphics card. The power supply has been upgraded to a 400-watt unit to support the additional power requirements. Despite this, the system’s motherboard detects no graphics card in the PCIe slot, and the card does not appear in Device Manager, indicating it is not being recognized by the system.

Common Causes and Initial Checks
Before delving into more technical solutions, ensure that the following basic steps have been completed:

• Power Supply Adequacy: Confirm that the 400W PSU provides sufficient power for the RX 580, which typically requires around 185W under load, plus additional headroom.
• Physical Seating: Verify that the graphics card is securely seated in the PCIe slot.
• Power Connections: Check that the GPU’s power connectors are properly connected.
• Monitor Connection: Ensure the monitor cable is connected to the GPU (not the motherboard’s integrated graphics port) and that the monitor is powered on.

Troubleshooting Steps

1. Verify BIOS Settings and Updates
2. Access the BIOS/UEFI firmware during startup by pressing the designated key (often F10, F2, or Delete).
3. Check if the PCIe slot is enabled and configured correctly.
4. Look for any settings related to integrated graphics and ensure they are appropriately set to support discrete GPU booting.

5. Update the BIOS to the latest version from HP’s official website to ensure compatibility with new hardware.

6. Test the GPU in a Different System

7. To rule out the possibility of a defective GPU, test the RX 580 in another compatible PC. If it’s recognized there, the issue may be related to your current system’s configuration.

8. Use a Different PCIe Slot

9. If your motherboard has multiple PCIe slots, try installing the GPU in an alternative slot to rule out slot-specific issues.
