FIX: GPU Fans Are Spinning, But There Is No Display

Spinning GPU fans does not always mean that your GPU is fine. This might indicate that your GPU’s synchronization to temperature is not working properly. GPU fans are designed to spin only if the GPU temperature is rising. But there is a situation when your GPU fans start spinning when you turn on your PC, but your display isn’t working at all. So, why are you stuck with no display, and how can you fix it in no time?

It is due to a misconfigured monitor input source, where the input setting on your monitor doesn’t align with the type of connection on your GPU. Moreover, faulty cables can be a cause if they are not correctly connected; you might encounter a no-display problem that leads to a black screen situation.

If the cables and connectors are secure, reposition the GPU within the PCIe slot. If you have display problems, check if the GPU’s power connectors are securely attached to the power source. You can narrow down the cause of the issue by trying several display ports and cables or connecting to integrated graphics (if available). It’s also a good idea to examine the BIOS or UEFI settings on your motherboard for any indications of alterations to the video output.

Here are the reasons why GPU fans are spinning but there is no display:

• Check Monitor and Cables
  If you’re trying to figure out why the GPU fans are running, but the screen is blank, paying close attention to the reliability of the connections will be an essential first step. It is crucial to properly secure both the monitor’s power line and the graphics card connector. A symphony of signals orchestrates your components’ digital communication; these links are the conductors.
• Monitor Input Source
  If your GPU fans are spinning, but you can’t see anything on your monitor, ensure it’s correctly configured to receive the signal from your graphics card. The monitor’s input may not match the type of connection on your GPU, like HDMI or DisplayPort.
  Modern displays support video input formats, including HDMI, DisplayPort, and VGA. There is a corresponding type of cable connection for each of these inputs. It is possible that the monitor is not displaying anything because of an incorrectly configured input source despite the GPU sending a signal.
• Check Power Connections
  To solve the problem of active GPU fans but no display, your graphics processing unit (GPU) needs a strong and reliable power supply. This thorough analysis is more crucial than ever because some graphics processing processors require more power than a typical PCIe slot can offer.
• Power Supply Issues
  The power supply unit (PSU) is the unsung hero of your computer system. It stores the power that keeps everything running. If your GPU fans are spinning and you’re not getting any display, the power supply unit (PSU) isn’t strong enough to keep up with the needs of your technological setup.
• BIOS/UEFI Settings
  In the complex world of troubleshooting, where digital interactions play the role of conductor, the BIOS/UEFI settings typically play a vital role. Here, the esoteric language of binary code and complex settings determines the fate of your device. If you’ve not skillfully selected the principal display output, you may face the issue of no display.
• Driver Issues
  Issues with the drivers can cause your screen to appear blank. If you don’t have the latest versions of drivers installed on your device, you may find yourself with a blank monitor screen. Go to the Device Manager to check out for any faulty drivers.
• System RAM
  The random access memory (RAM) modules are like bright sentinels guarding the memory and performance of your computer deep within its sophisticated inner workings. They store the digital life force that drives the harmonious performance of your system’s many processes. There is, however, room for discord within this symphony, and if it does, it could cause mysterious boot and display problems.
• Other Hardware Issues
  Conflicts inside your computer system can sometimes arise from other hardware components, bringing complexity that impairs the smooth running of essential tasks and adding to the already complex landscape of troubleshooting. When you see your GPU fans running but notice no visual output, you must look further than the obvious and analyze how other components might interact to cause the problem.

How to Fix GPU Fans Spinning But There Is No Display?

You can fix this issue by giving the GPU the power it needs. You can do this by ensuring that you connect the PSU and other power cables. Another way is regularly cleaning the fan blades, as debris and dust accumulation can cause the GPU fan to malfunction.

Having your graphics card’s fans running without visuals is frustrating and perplexing. The graphics card may not communicate correctly with the display, or another component may have a problem. Checking sure your monitor is powered on and properly connected to the GPU via the proper cable (HDMI, DisplayPort, etc.) is the first step when troubleshooting.

If the cables and connectors are secure, reposition the GPU within the PCIe slot. If you have display problems, check if the GPU’s power connectors are securely attached to the power source. You can narrow down the cause of the issue by trying several display ports and cables or connecting to integrated graphics. It’s also a good idea to examine the BIOS or UEFI settings on your motherboard for any indications of alterations to the video output.

If these troubleshooting measures don’t work, you can diagnose overheating issues, check other hardware components, install updated drivers, or even try the GPU in a different system. If troubleshooting the problem on your own has failed, you may need the assistance of a hardware expert.

Ensure GPU is Getting Power

If your display is malfunctioning, check if the GPU gets enough power from the power supply and the correct power connectors before diving into more complex fixes.

• Verify that the GPU is receiving an adequate supply of power. Ensure the power supply unit (PSU) is correctly connected and all cables securely plugged in.
• Check that your power supply can meet your computer’s and graphics card’s demands. Choose the best PSU. It may be the solution if your graphics card’s fans aren’t turning. 

Clean Fan Blades

Dust accumulation could clog a GPU fan, causing it to malfunction. You can clean the fan and heatsink by blasting them with compressed air. Remember to keep the compressed air can upright and the nozzle safe from the fan to prevent malfunctions. You can wipe off dust or debris on the fan blades using a clean, dry cloth or a soft-bristled brush. A cotton swab dampened in rubbing alcohol can also clean them.

Adjust Fan Curve Settings

Users can fine-tune their graphics card’s fan speed in response to environmental temperature readings with the help of GPU fan curve control. You can fix the problem by utilizing a tool to adjust the fan curve parameters—this aids in keeping the GPU at an optimal temperature with little fan noise. You can install software such as MSI Afterburner, EVGA Precision, and ASUS GPU Tweak to enable GPU overclocking and fan control.

Double-Check Your HDMI And DisplayPort Cables

The wires themselves, or a loose connection (i.e., one end of the cable has pulled out), could be to blame if the problem suddenly appeared on an already-established PC configuration.

• Inspect the cable’s length to ensure it is not physically damaged anywhere along its length.

• The next step is to double-check that the cables are plugged in properly to the motherboard and the graphics card. If the cable ends appear dusty or dirty, you can blow some air over them before plugging them back in.
• Repeat the process with the wires behind your screen.

Ensure Your Display Cable Is In Your GPU

It’s important to remember that the GPU, and not the motherboard, should be where you hook in your display wires. If you accidentally connect the display wire to your motherboard rather than your monitor, your computer will only produce visual output if it has the necessary hardware. In this scenario, the graphics card is always where you’ll want to connect your monitor’s wires. Make sure the motherboard display cable slots are free by quickly checking under the computer.

Reinstall Your Graphics Drivers

You should immediately reinstall your graphics drivers if you discover that you can occasionally start up (with display). If your system occasionally starts up without a display, this can help you find and fix the underlying cause.

• Simply visiting the AMD driver download page or the NVIDIA download page and selecting your GPU model will begin the installation process. It will direct you to the correct driver download page for your computer.
• The next step is to open the file you downloaded by double-clicking on it.
• If you’re having trouble seeing anything on your screen, try installing the whole display software suite or only the display drivers.
• Once you’ve finished, try a system restart to see if you always boot up with a display on your monitor. After reinstalling the drivers, the issue usually disappears for a while. However, it can return later and prompt me to do so.

Put Your BIOS Back To Factory Defaults

If you have extensively modified the BIOS, reset it to factory settings to see if this resolves your display issues. If they do, try rolling back your settings one by one until you find the one responsible for the display issue.

Moreover, if you’re concerned that your overclock might cause the problem, you could try lowering it to see if it helps. Give more juice, or run your CPU (or RAM) slightly slower. It can be challenging to determine the source of an unstable OC if the system is almost booted up (with fans spinning and LEDs lit but no final display on the screen).

Re-plug Display Cable

In a rush to find a quick fix, you should realize that simply re-plugging your display wire into your GPU and monitor will restore functionality to a previously non-responsive display.

• Verify that the video card and screen have a solid connection by checking the cable.
• Similarly, make sure to insert the cable into the port correctly. You can test if the problem still exists after you detach and reconnect.
• If your graphics card’s fans aren’t turning, but your screen still isn’t showing anything, try switching to a different cable to see if it helps.

Fixing the Internal Connections

Finally, internal connections are another typical issue with graphics cards under these conditions. If you are putting together a brand new structure, this is probable.

• Multiple power connectors and PCI Express slots are standard for modern graphics cards.
• Double-check all the connections to ensure proper setup.
• Ensure you securely reinsert each plug, just as when checking exterior connectors. Check the plug if the fans are getting power but the display isn’t.
• The manual for your motherboard should include instructions on how to install a video card. You can double-check your knowledge by searching for video guides online.
• Let’s say the issue manifests itself in a previously stable build, and you still need to change the computer’s internals. A faulty internal connection is highly improbable, given the circumstances.

What to Do If GPU Fans Are Not Spinning After Cleaning?

If the GPU’s fans stop spinning after cleaning, check that the power cables are securely connected and that the GPU is properly seated on the motherboard. Check for broken links after you’ve finished cleaning. If the issue persists, contact the manufacturer or a specialist.

After cleaning your GPU, reinsert it into the computer and thoroughly test its performance. You need to do this to ensure it matches its state before removal. Inspect the lights and temperature gauge frequently. If the fans aren’t turning, you should take them apart again and inspect the blades for damage. While disconnected from the computer, perhaps something got in the way of the blades.

If you disassembled the GPU to clean it and are considering doing so again, you should read on. Ensure the screws are in and the fans are mounted properly before putting them back together again. If you still need to take the GPU apart, you need only inspect the fans for dust. Only experienced computer hardware disassemblers or qualified computer repair specialists should disassemble a graphics card.

Tips for Better Spinning GPU Fans

These tips encompass various aspects, from controlling the GPU fan curve to checking the GPU on different systems and returning it to the manufacturer to promote efficient fan spinning and contribute to a smoother, efficient system overall. It would help if you got to the issue’s root to solve it.

If your GPU’s fans aren’t performing as well as they should, you could miss a much better computing experience. You can keep your GPU cool and its fans running efficiently by employing various tried-and-true techniques.

• Control the GPU Fan Curve

A GPU’s fans usually begin spinning once the component reaches a predetermined temperature. The fans speed up to keep the card cool as the temperature increases. Adjusting the fan curve can achieve earlier fan rotation than the default.

A typical fan curve plots temperature versus fan speed for the graphics card. A misconfigured fan curve could be the blame if your GPU cooling fan isn’t turning. MSI Afterburner is one of several programs that can modify the GPU fan curve.

Alternatively, you can utilize AMD Software with an AMD card. Launch the application and navigate to performance> Tuning > Custom to activate Fan Tuning and Advanced Control. You can adjust the fan rotation rate in response to a given temperature here.

• GPU Testing on Different Systems

You should borrow a friend’s PC and test your GPU there. Using this method, you can pinpoint if the issue is with the graphics card or another part of the computer. As an illustration, if your GPU’s fans aren’t turning, it could be a symptom that your power supply is malfunctioning. You can use the GPU-Z software to stress test your GPU.

If the card is functional in another system, the challenge will be identifying the faulty component in your primary setup. The power supply unit, the PCIe cables, or the motherboard could be at fault. Try replacing them to see if the GPU cooling fans start up again.

• Return the GPU to the Manufacturer

If all else fails, it’s probably a bad GPU. If you are confident in doing such surgery, consider replacing the GPU fans independently. However, if your GPU is still under warranty, you can return it to the company and get a new one.

Conclusion

In conclusion, it can be very confusing and annoying for a computer user to experience a situation where the GPU fans are running, yet there is no display. This issue may have multiple causes, from a faulty connection to more advanced hardware or software. Identifying the issue’s potential causes and taking a systematic approach to fixing it can help.

The essential first steps to diagnose and fix the issue include ensuring the monitor and cables are correctly connected, reseating the GPU, checking the power supply connections, testing various cables and ports, and confirming BIOS/UEFI settings.
