We have noticed a peculiar issue where the system has no display but the GPU fan is spinning. Sometimes, even the GPU’s RGB lights up indicating that the device is getting powered, but the monitor just doesn’t respond. In this post, we will see what to do if there is no display but the fan is supping.
Why is my GPU not detected but the fan is spinning?
There is a high chance the device connecting the GPU to the motherboard or the monitor cannot carry the amount of power required to power up the monitor. However, this can also be a glitch. After this, we will discuss all the potential solutions you can try to resolve this issue.
Fix GPU No display but Fan spinning on Windows PC
If there is no display but the GPU Fan is spinning on your Windows 11/10 computer, follow the solutions mentioned below.
- Disconnect all peripherals and cables, and reconnect your monitor
- Replace the VGA Cable
- Disconnect and reconnect the GPU Power Cable
- Remove or replace the CMOS Battery
- Uninstall the display driver
- Run the system using the integrated GPU to see if the problem lies with the Monitor
Let us talk about them in detail.
1] Disconnect all peripherals and cables, and reconnect your monitor
First, disconnect all your peripherals, such as your external webcam, mic, mouse, keyboard, and others, and then test to see if you are facing the same issue. If you are, you need to detach all the cables, if you have not done that already, and then plug them back in. This allows your capacitors to discharge, which might resolve the issue.
To troubleshoot the issue, it’s important to ensure that your monitor and computer are properly connected without any loose cables. Start by turning off your PC, unplugging the power cord, and disconnecting the video cable from the monitor. Then, reconnect the video cable and ensure all other cables are properly attached. Finally, turn on your computer to see if the issue has been resolved.
2] Replace the VGA Cable
Next, we urge you to replace the VGA Cable connecting your monitor to the CPU. Since these are not expensive, you can replace them and see if there is any problem with them. If replacing the cable does not help, we will move on to the next solution.

3] Disconnect and reconnect the GPU Power Cable
There are two cables (or one in some cases) at the back of your GPU. You need to unplug them from the motherboard and then plug them back in. For some, the simple act of disconnecting and reconnecting the GPU Power cable worked. If this doesn’t work for you, replace the cable and see if that helps.
4] Remove or replace the CMOS Battery
The CMOS (complementary metal-oxide-semiconductor) battery, also known as the coin-cell battery on the motherboard, helps the BIOS or UEFI to store hardware configuration settings. It maintains the date and time when the computer is switched off. Since we are facing an issue, we can try disconnecting and reconnecting it, allowing it to lose its charge. If that doesn’t work, you can replace the CMOS Battery, as there is a possibility that the battery has malfunctioned.
5] Uninstall the display driver
In order to uninstall the display driver, we need to boot up your system. For that, we will have to remove your GPU (the dedicated one) and then plug the display directly into the motherboard so that it boots up using the integrated or on-chip graphics. If the device boots up, you can follow the steps mentioned below to uninstall the display driver.
- Hit Win + X and open Device Manager.
- Expand Monitor or Display adapters option.
- Right-click on the display driver (Intel, AMD, etc) and select Uninstall device.
- Check Delete device software for the device.
- Click on Uninstall again.
- Once the driver is uninstalled, shutdown your PC, and reinstate the GPU (make sure that the connection is firm).
- Finally, turn the device back on.
Hopefully, this will do the job for you.

6] Run the system using the integrated GPU to see if the problem lies with the Monitor
Next up, we recommend you remove the dedicated GPU and run the device on the integrated one to see if there is some issue with the Monitor or some other component of your computer. If you can start your computer after removing the dedicated GPU, we need to see if there is some issue with the port. So, you need to borrow your friend’s GPU and then connect it to your device. If everything starts booting up, you know your GPU is at fault; hence, you must visit the manufacturer and ask them to repair or replace the component.
Hopefully, you get an idea of how to resolve this issue.

Why is my Graphics card lighting up but Fans not spinning?
If the GPU is lighting up but the fans are not spinning, you need first to check if your GPU is actually hot; if it’s cold to touch, there is no point in running the fan. Also, you need to ensure that the GPU has enough power supply and all the cables are connected perfectly. Additionally, check the fan’s settings in the OEM’s utility and clean any dust and debris that could have stopped fans from spinning. You can check our guide to know what to do if GPU fans are not sipping.
