Check Power Connections
Power connections are a common cause of GPU issues. Even if the fan spins, your GPU may not show any display. Checking power cables and compatibility is a good first step. It ensures the GPU receives enough power to work properly.
Loose or faulty cables can stop the GPU from working. Sometimes the power supply unit (PSU) may not match the GPU’s needs. Both parts must connect well and provide enough power for the GPU to run.
Inspect Gpu Power Cables
Start by turning off your computer and unplugging it. Open your PC case carefully. Look at the power cables connected to your GPU. Make sure all cables are firmly plugged in. Loose cables cause power problems and no display.
Check for any signs of damage on the cables. Broken or bent pins can stop power flow. Try unplugging and plugging the cables back in. This simple step can fix connection issues. Use only the cables that came with your PSU or GPU.
Verify Psu Compatibility
Not all power supply units support every GPU. Check your GPU’s power needs in its manual or online. Look for the required wattage and connector types. Your PSU should match or exceed these requirements.
Older or weak PSUs might not supply enough power. This causes the GPU fan to spin but no display appears. If your PSU lacks the right connectors, use adapters carefully. A poor connection can cause damage or failure.
Consider upgrading your PSU if it does not meet your GPU’s power needs. A compatible PSU helps your GPU work without issues.

Clean the PCIe slot lightly with compressed air. Dust blocks cooling and can cause display problems. Keeping the GPU clean improves performance and prevents overheating.
Test With Another Monitor Or Cable
Testing your GPU with another monitor or cable helps find the cause of no display. The GPU fan spinning means power is on, but the image might not show due to connection problems. This test removes doubts about cables or monitor issues. It saves time and prevents unnecessary repairs.
Swap Display Cables
Start by changing the cable that connects your GPU to the monitor. A broken or loose cable often causes no display problems. Use a new or known working cable to test. Make sure the cable fits tightly into both the GPU and monitor ports. Check for bent pins or damage on the connectors. Try different cable types like HDMI, DisplayPort, or DVI to see if one works better.
Try Different Monitor Or Port
Next, connect your GPU to another monitor. This step shows if the original monitor is the problem. Use a monitor that you know works well. Also, try plugging the cable into a different port on the GPU. Some GPUs have multiple outputs. Testing different ports helps find a faulty port issue. If the display works on another monitor or port, the problem lies there, not the GPU.
Update Or Reinstall Gpu Drivers
Updating or reinstalling GPU drivers can often solve the problem of no display while the GPU fan spins. Drivers are the software that helps your computer communicate with the graphics card. Outdated or corrupted drivers can cause display issues. Fixing this can bring your screen back to life quickly.
Start by safely accessing your system to avoid further problems. Then, download the correct driver version for your GPU model. This ensures compatibility and smooth performance. Follow each step carefully for the best results.
Boot Into Safe Mode
Safe Mode starts your computer with only essential drivers. This helps avoid conflicts during driver updates. To enter Safe Mode, restart your computer and press the correct key (often F8 or Shift+F8). Choose “Safe Mode with Networking” to have internet access. This way, you can download new drivers easily.
Download Latest Drivers
Visit the official GPU manufacturer’s website to find the latest drivers. Select your GPU model and operating system carefully. Download the newest version available. After downloading, run the installer and follow the instructions. Restart your computer to apply changes and check if the display works.
Check Bios And Firmware Settings
Checking BIOS and firmware settings is key to fixing a GPU that shows no display but has a spinning fan. BIOS controls how your computer hardware works together. Sometimes, incorrect BIOS settings cause the GPU not to display output. Firmware updates also improve hardware compatibility and fix bugs.
Start by resetting BIOS settings. This step clears any wrong configurations that block the GPU from working. Updating the motherboard BIOS can also help. It ensures your system supports the latest GPUs and hardware changes.
Reset Bios To Default
Resetting BIOS to default removes custom settings that may cause problems. To do this, restart your PC and enter BIOS setup. Usually, press Delete or F2 key during startup. Find the option labeled “Load Setup Defaults” or “Reset to Default.” Select it and save changes. After this, restart your computer. This simple step can fix the no display issue.
Update Motherboard Bios
Updating the motherboard BIOS can fix compatibility issues with newer GPUs. Visit your motherboard manufacturer’s website. Download the latest BIOS version for your model. Follow the instructions carefully to update BIOS. This process varies by brand but usually involves a USB drive. Keep your PC on and do not interrupt the update. A successful update can solve display problems caused by outdated firmware.
Diagnose Hardware Issues
Diagnosing hardware issues is the first step to fix a GPU with no display but a spinning fan. The problem often lies in the physical components or connection. Checking the hardware helps find the exact cause. This saves time and prevents unnecessary expenses.
Test Gpu In Another System
Remove the GPU from your computer. Install it in a different, working system. This test shows if the card works properly. If the GPU still has no display, the card may be faulty. If it works well, the problem might be in your original system. Testing in another system isolates the problem clearly.
Look For Physical Damage
Inspect the GPU carefully. Check for burnt marks or scratches. Look at the connectors and pins for any damage. Dust or debris can also cause issues. Clean the GPU gently with compressed air.
