Troubleshooting a GPU That’s Running but Not Displaying: A Guide for Gamers

If you are experiencing issues with your computer where the GPU fans are spinning at full speed, yet there’s no signal reaching your monitors, you’re not alone. This frustrating situation can happen to anybody, and I recently found myself in a similar predicament. After successfully booting up, I encountered a sudden loss of video signal while using my desktop. Here’s a detailed account of my troubleshooting journey, along with some insights on how to tackle this issue.

The Initial Problem

Upon starting my computer, everything seemed to be functioning normally. However, while I was navigating through my desktop, both monitors abruptly lost their signal. Restarting my machine did not resolve the problem; instead, I noticed that the GPU’s fans were running at maximum RPM. Clearly, something was amiss with the graphics card connection.

Troubleshooting Steps Taken

In an effort to diagnose and resolve the issue, I undertook several troubleshooting steps:

  1. Clearing the CMOS: This reset the BIOS settings and can sometimes restore normal function, but it did not help in this case.

  2. RAM Configuration: I attempted to boot the system using just one stick of RAM to eliminate the possibility of faulty memory, but the problem persisted.

  3. GPU Reseat: Carefully removing and reseating the graphics card and all RAM sticks is crucial. I ensured that everything was clean and well-connected, yet there was still no signal.

  4. PCIe Slot Limitation: Unfortunately, switching the PCIe slot was not feasible due to space constraints with surrounding wires and fans.

  5. Integrated Graphics Check: I switched to integrated graphics to see if my GPU was being detected by the system. Regrettably, it was not recognized, signaling a potential issue with the graphics card itself.

System Specifications

For context, here are the specifications of my build:

  • Processor: Intel i7 9700K
  • RAM: 32GB Trident Z 3200MHz CL16
  • Motherboard: Asus Z-390
  • Graphics Card: EVGA 2070 Super
  • Additional Components: Various fans and NVMe storage units

Seeking Assistance

Despite my extensive troubleshooting efforts, I’m still at a standstill and could use some insights from the community. If anyone is familiar with this issue or has

  1. Hello,

    Based on your description, it seems like your GPU might be experiencing hardware failure, especially since you’ve already tried reseating the card, testing with integrated graphics, and clearing the CMOS. Here are a few additional suggestions you might consider:

    • Test the GPU in another system: If possible, try installing the EVGA 2070 Super into a known working machine to see if it displays output. This can help determine if the card itself is faulty.
    • Check for any physical damage: Inspect the GPU for visible signs of damage, such as burnt components or broken fans. Also, ensure that the PCIe slot and power connectors are clean and undamaged.
    • Power supply considerations: Verify that your power supply is providing sufficient wattage and stable power to support the GPU, especially during full load. Sometimes, insufficient power can cause fans to spin without proper signal.
    • Update motherboard BIOS: Make sure your motherboard BIOS is up to date, as outdated firmware can sometimes cause compatibility issues with newer or different GPUs.
    • Test with different display outputs: If your GPU has multiple display outputs, try connecting your monitor to different ports (HDMI, DisplayPort, DVI) to rule out a faulty port.
