GPU Fans Not Spinning No Display – 4 Reasons and Solutions

The GPU fans fail and spin and output display when the display and power cables are faulty/loose. To get the display, swap out faulty cables and tightly connect all cables. Then, reinstall the RAM sticks properly. After that, connect your GPU with a PSU that’s powerful enough, if not already. Lastly, reset the BIOS to flush out any technical errors.

Although you’ll need this information, you also need a proper guideline to fix GPU fans not spinning no display entirely. Read the article till the end!

GPU Fans Not Spinning and No Display: Quick Fixes

I have accumulated the possible reasons and their quick fixes for this issue and listed them in the table below. Have a look to get a better idea-

Reasons	Symptoms	Solutions
No power	GPU RGB light not working	Check if any cables are loose and reconnect them Check the cables and power your GPU with the appropriate power cable
RAM instability	Uneven Reboot loop	Check and reinstall the RAM sticks
Bottlenecking of the PSU	GPU not getting enough power from the PSU Reboot loop	Connect your GPU with a powerful enough PSU
BIOS errors	GPU fans are not working and there’s no display despite getting power	Reset the BIOS

GPU Fans Not Spinning and No Display: Detailed Solutions

Let’s get to the detailed step-by-step solutions to the problems and issues mentioned above.

Reason 1: No Power

The GPUs are usually powered by 4/6/8-pins and the display cables use VGA/HDMI/DP cables. Additionally, there might be loose connections or faulty power/display cables. Due to that, the GPU won’t output display or get any power from the PSU.

A loose connection can happen on both sides; with the GPU and PSU’s connector. On the other hand, if your GPU’s fans are spinning but it’s not providing a display, then it’s most likely a faulty cable.

Solution: Check the Cables and Power the GPU

Start off by checking for loose connections and also check if you’re using the appropriate power cables to power the GPU. Here are the steps to do so:

• First, tighten the cable powering the GPU. Also, the extension coming from the PSU.
  
• Then, check if the pin count of the power cable matches with the GPU’s power input. In a lot of cases, 4-pin plugs are used in 6-pin ports, and 6-pin plugs are used in 8-pin ports. It’s a common bad practice and it can harm the GPU.
  
• Finally, check if all the connectors are correctly connected to the PSU. This goes for both the GPU and motherboard. If you have a high-end and powerful motherboard, chances are it’ll use 2 cables; 24-pin and 6/8-pin. Connect both.
  

You need to also check the display cables if the fans of your GPU are spinning but there’s no display output. Try the display cable with other PCs to verify the functionality. If it’s not working, swap out the old display cable with a new one!

Reason 2: RAM Instability

When your PC keeps booting and there’s no display and no spinning of GPU fans, this is most likely the case.

If the RAM sticks are installed incorrectly, it can cause the GPU, CPU, and motherboard not to boot properly. The computer will probably stuck on a bootloop; starting but rebooting after a few seconds. It can also prevent the computer’s uptime from resetting.

Solution: Check and Reinstall the RAM Sticks

To solve the issue with the RAM instability, take out your RAM sticks. Then, clean the contact pins of the RAM. After cleaning the RAM sticks, reinstall them. Cleaning the RAMs eliminates the chances of boot failure due to dust or debris.

If the boot loop is still not fixed and you have multiple RAM sticks, try putting in only one RAM stick and booting. Keep trying with one stick of RAM until the PC boots properly and the GPU provides a display.

After that, you can install the other RAM sticks. Don’t forget to push down the retaining clips to hold the RAMs in place.

Reason 3: Bottlenecking of the PSU

GPU is the most power-hungry unit of any PC. Each GPU has a power requirement given by the manufacturer of the GPU.

In many cases, the PSU of a PC is too weak to power the GPU. This causes a bottleneck, which in turn causes the GPU to get no power.

Also, note that the fans of a GPU are not always meant to spin while booting up. In some GPUs, the fans only spin after the GPU reaches a certain temperature. But if the fans aren’t working when the GPU is heated, it indicates an issue.

Solution: Connect Your GPU with a Powerful Enough PSU

To connect your GPU with a powerful enough power supply you’ll need to do some calculations. Here are the steps:

• Determine how much power your PC uses by combining all the components (GPU, CPU, motherboard, etc). Heads up, you might be surprised about how much electricity gaming PCs use!
  
• Then, if you’ve found your desired PSU, make sure it fits well inside your gaming case.
  
• Finally, make sure the ventilation of the PSU is proper. High-end PSUs use more power and generate more heat, so you may need an extra casing fan or two to dissipate said heat.

Reason 4: BIOS Errors

Errors in the BIOS can cause a range of problems on your PC. Starting from the GPU not booting up, powered USB ports not being recognized, component failure, etc.

If there’s any error in the BIOS that affects the microprocessors of the GPU, the GPU might not boot. 

Solution: Reset the BIOS 

To avoid BIOS errors in a gaming PC, you need to reset the BIOS. Here are the steps to do so:

• First, turn off your PC and use a metal screwdriver to hold the start pins on your motherboard together for 10-15 seconds. This will let all the stored power out.
  
• After that, take out the CMOS battery from the motherboard. After waiting 5 minutes, put it back in. Some higher-end motherboards have a dedicated CMOS clearing button as well!

• Finally, go into BIOS settings and reset to factory default. After that, save the changes and boot up your PC.

Wrapping up

That’s everything on the issue related to GPU fans not spinning no display. If your problem persists, you can consider taking the GPU to the warranty center. If you still have a warranty, the GPU manufacturer can fix or replace the unit for you. Best of luck.
