Here’s what to do if your computer won’t boot but the fans are spinning:

First Method To Fix PC Starts Up; Fan works But No Display

1. Remove any external hardware.

2. RAM chips should be reset.

3. Examine the motherboard

4. Replace the power outlet

5. Check with the manufacturer of your computer.

6. Examine the peripherals

7. Consult a technician

  1. Remove any external hardware.

You have to unplug or disconnect any external hardware, such as printers, USB drives, and scanners, so that only the essential components remain before attempting again.

Of course, we recommend unplugging the power cord and removing all external peripherals before moving on to the internal hardware.

  1. Reboot the RAM chips

A lousy RAM module could be one of the reasons your computer won’t boot but the fans spin.

Remove the RAM from its slot, clean it, and then reinstall it in the same slot or try a different slot entirely.

The best way to clear RAM is to use a soft cloth. Don’t use any liquid. You can also try switching the RAM card positions to different sockets.

We recommend that you replace your RAM. Using a brand new DDR4 memory module avoids the situation where your computer does not boot but the fans spin.

There are professional products with a 1.2 V operating voltage in this category. Their design allows for low power consumption and the use of a product with low generated heat.

Overall, your computer will have a constant ambient temperature, avoiding overheating. A professional DDR4 memory module provides long-term stability, efficiency, and low consumption.

  1. Examine the motherboard

If you notice a yellow or amber light, it could indicate a faulty motherboard. Sometimes the motherboard has bad capacitors, which causes the computer not to boot but the fans to spin.

If this happens, you might need to replace it with a new one.

  1. Replace the power outlet

Open your computer, remove all connected devices and expansion cards, and then restart it, and it still won’t boot, but the fans spin; you’re probably dealing with a power supply problem.

As previously stated, one of the reasons your computer may refuse to boot but the fans spin is a faulty power supply. You can try a different wall outlet and plug into it before attempting to restart your computer.

  1. Check with the manufacturer of your computer.

If your computer won’t boot, but the fans are spinning, take note of the sequence of beeps or flashing lights your computer displays while attempting to boot.

The next step is to find out what the sequence means from your computer’s manufacturer.

  1. Examine the peripherals

If your computer won’t boot, but the fans spin and you hear a beep sound as if it’s booting, one of your peripherals may be the culprit.

In this case, you can try inserting one at a time to see which one is faulty.

  1. Consult a technician

If all else fails, contact a qualified computer repair technician to determine the nature of the problem and how to resolve it. This could be (and usually is) a power supply failure.

You’ll almost certainly need to replace it. It frequently has enough power to run the fan (low-power) but struggles to run anything else.

If you cannot access BIOS Setup, try removing and replacing the CMOS battery and reconfiguring BIOS settings (Optimal Load Settings, Set System Time/Set System Date).

  • Step4:

If you still cannot access BIOS Setup, try removing and replacing the CMOS battery again (after waiting 10 seconds) and then reconfiguring BIOS settings (Optimal Load Settings, Set System Time/Set System Date).

  • Step 5

If you still cannot access BIOS Setup but can boot to Windows (Windows 7 or later):

  • Step 6

Go to Start > All Programs > Accessories > Command Prompt. Type MSConfig in the search box or open Run. Click on the Boot tab and select Safe Boot; click OK. Restart the system when prompted. When the system restarts, it will boot into Safe Mode with Networking. Go to

If you are experiencing this problem, follow these steps to troubleshoot:

  1. Unplug your desktop PC and remove the power cord.
  2. Open up your desktop PC, so that you can access the motherboard.
  3. Locate the CMOS battery on the motherboard. The CMOS battery is a 3 volt lithium battery. It should look like the image below:
  4. Remove the CMOS battery and wait 5 minutes before reinserting it into its slot on the motherboard.
  5. Close up your desktop PC, plug it back in and reconnect the power cord.
  6. Turn on your computer as normal and see if you can boot to Windows normally again.

Fourth Method To Fix PC Starts Up; Fan works But No Display

The first thing you should do is to try and start the PC in Safe Mode.

To go into Safe Mode, start your computer up and when you see the Windows logo, begin tapping F8 on the keyboard. This should take you to a menu where you can choose to start in Safe Mode.

If it starts in Safe Mode, it is a driver issue that can be resolved by downloading and installing new device drivers.

You can figure out what these are by starting your PC up typically, opening Device Manager (right-click on My Computer, choose Properties, click on Hardware tab, then click on Device Manager), and looking for anything that has a yellow exclamation point next to it. If you find something, note down what exactly it is.

Suppose it won’t start in Safe Mode either. There are still some things you can do, though. Power down the computer again and check all connections inside the box. Ensure everything is seated correctly and no loose cables or wires are floating around.

Also, check for any bulging capacitors on the motherboard (they look like little cylinders with a flat top). If any of them are bulging or leaking fluid, they’re bad and will need to be replaced.

There are three main reasons why your computer will not boot but the fans will spin:

  • Insufficient power supply
  • Overheating
  • Components that failed

When your computer’s power supply fails, it will not start or power up, but the fans will continue to spin.

Similarly, if your computer won’t boot, but the fans keep spinning, it could be a sign of high temperatures or overheating.

If not addressed, this can cause your computer to fail or refuse to boot until it has cooled down.

If your fans spin faster than usual, make sure the airflow around them is not obstructed.

When the components of your computer are faulty or damaged, they can prevent your machine from booting. RAM chips, motherboards, and even the BIOS are examples of such components.

Conclusion

I’d like to believe you now know how to fix the issues you had with your computer fans spinning when your computer isn’t booting.

Let’s know if any of these solutions worked for you.
