A solid white light on the CPU EZ Debug LED usually means an issue with the CPU or its connection. This could happen if the CPU isn’t seated correctly, if there’s a power problem, or if the CPU is faulty.

Make sure the CPU is installed correctly and that all connections are secure. If the light remains on, try testing with a different CPU.

Common Causes of White CPU Light and No Display:

1. Improper CPU Installation:

If the CPU is not seated correctly in the socket, it can prevent the motherboard from recognizing it. This may happen if the CPU pins are bent or if the CPU is incorrectly aligned. Carefully removing and reinstalling the CPU can resolve this issue.

2. Outdated BIOS:

An outdated BIOS can lead to compatibility issues with newer CPUs. If the BIOS version is not updated, the motherboard might not recognize the CPU. Checking the MSI website for the latest BIOS version and following the update instructions can often fix this problem.

3. Incompatible CPU:

Using a CPU that is not compatible with the MSI MPG B550 Gaming Plus motherboard can cause the white CPU light to appear. It is essential to verify the CPU’s compatibility with the motherboard by consulting the motherboard’s manual or MSI’s official compatibility list.

4. Loose or Faulty Connections:

Loose connections between the CPU, motherboard, and power supply can lead to the CPU light being on and no display. Ensure all cables are securely connected, including the power cable to the CPU and any other relevant connections.

5. Power Supply Issues:

A malfunctioning or insufficient power supply can fail to deliver the necessary power to the CPU. This can cause the system not to start properly, resulting in the white CPU light. Ensure that the power supply meets the recommended wattage for your components and is functioning correctly.

6. Faulty Hardware Components:

Defective hardware, such as a damaged CPU or motherboard, can cause the white CPU light to illuminate. If all other troubleshooting steps fail, testing with different components or having them checked by a professional may be necessary to identify any faulty parts.

7. RAM Problems:

Faulty or improperly installed RAM can cause the white CPU light and no display. If the RAM sticks aren’t in their slots correctly or aren’t compatible, the motherboard might not start. To fix this, remove the RAM and put it back in securely, or try using different RAM sticks to see if that helps.
