MSI EZ Debug LED – How To Troubleshoot and Fix[Guide]

The EZ Debug LEDs help determine whether the problem is with your DRAM, VGA, CPU, or a boot issue. They illuminate and indicate which component is faulty. As a result, you can inspect the affected component using the illuminated LED indicator.

Turning on a PC after building can be quite stressful. This is because, most times, the display will show nothing. You might have carefully assembled all the components. Yet there could be some mistakes here and there. Figuring out what the mistake is can be a difficult task.

You must, however, be certain that your motherboard comes with EZ Debug LEDs. You can verify this from your motherboard’s manufacturer manual. You can also check the right-hand corner near the DIMM slots.

MSI Debug LED Code List and Description

how to troubleshoot and fix EZ Debug LEDs

The LEDs on your motherboard come in the following order:

1. CPU: indicates the CPU is not detected or has failed
2. DRAM: This indicates that DRAM is not detected or has failed.
3. VGA: indicates that the GPU is not detected or has failed.
4. BOOT: indicates the boot device is not detected.

They usually appear on your motherboard in that sequence. You will also see it written out. Now that we know what EZ Debug LEDs represent let’s see how to fix the errors they indicate.

You first need to make sure that your motherboard can handle the parts you want to add. You can just check MSI’s website. You will see the support tab in the top right-hand corner. You will see a list of all the components supported by the motherboard.

Putting a good and meticulous plan in place in building your computer is important. It helps ensure that the components have no issues with compatibility. It also makes sure that they work hand in hand to optimize performance.

So, let’s look towards troubleshooting each component.

1. CPU EZ LED (Red Light )

The first thing to verify is if the CPU’s 4-pin or 8-pin power connector has been properly installed. You should then remove the CPU and check for any damages. There might be dirt blocking the connection to the socket. Clean and re-install the CPU.

You also need to verify if there are any broken or bent pins. You can fix bent pins with a needle. You also must verify if the motherboard and BIOS are compatible with the CPU.

How to Fix Ez Debug Led CPU

1. Check that you have connected the 8-pin CPU power connector.
2. Make sure all the RAMs are pushed all the way into the
3. Check that you haven’t unseated the VGA card. If you’ve tried the RAM, try reseating the video card.
4. Double-check to make sure you don’t have any bent CPU pins.
5. Take out the Cmos battery on the motherboard and boot without it, and see if it starts. If it does boot, put the Cmos battery back in and boot again like normal and see if it works.
6. Update your bios to the latest version.
7. If you have spare parts, swap the VGA, CPU, RAM, and PSU to narrow down the problem.
8. If none of these fixes work, then you have a friend’s motherboard; go ahead and RMA the board as soon as possible.

2. DRAM EZ LED

This usually indicates a problem with the RAM, either they are not properly seated or they are corrupted. There might also be a problem with the pins on the ram slot.

How to Fix Ez Debug Led Dram

Before troubleshooting the DRAM, you should know that bent CPU pins can illuminate DRAM LEDs. So, a good place to start is to ensure that the DRAM has been properly installed. Remove the RAM modules and check for any obstructions to the connection.

Then, install the DRAM stick into the memory slot from the CPU. Work with the second memory slot. Ascertain that it is securely fastened in place. You also need to check if the RAM fits the motherboard’s configuration. If you use multiple RAM sticks, ensure they are not in the wrong slots.

3. VGA

So, if the VGA light is the one appearing, it is a pretty straightforward issue. It is quite simple if your CPU comes with an integrated graphics processor. Just work with the information we have provided.

If it comes with a separate graphics card, ensure it is well connected to the PCIe socket. You can try out the socket closest to the CPU first. If it does not work out, then try the other sockets. The 8-pin connector has to be plugged into the graphics card properly. Make sure the pins are clean, though, before you install.

How to Fix Ez Debug Led VGA

1) Unplug the MotherBoard’s components and devices before reinstalling the CPU, RAM (one piece), VGA card, and power supply. Please apply thermal gel to the CPU before reinstalling the fan properly and tightly. To ensure the motherboard’s stability, connect JPWR1 and JPWR2 to proper ATX power supplies. Please ensure that the 6 or 8 pin power connectors on your VGA are connected to a power supply.

2) Clear the CMOS (consult the manual for instructions).

3) If the problem persists, please replace the VGA with a different VGA slot and test again.

I solved the problem by unplugging every PCI card from the motherboard. Then I reset the CMOS by short-circuiting the two pins with a screwdriver for 10 seconds (as instructed in your motherboard manual), and the situation improved slightly. I was then able to enter the BIOS and update it. Remember to wait at least 30 seconds after pressing the power button. The Windows 10 installation program then booted up without a hitch from the USB.

4. BOOT

The Boot EZ Debug LED has to do with the storage unit of your computer. You have to ascertain that all storage devices have been properly connected. For M.2 SSDs, you have to check if the pins are clean. They must also be properly installed. Verify that the SSD has been locked in place by the screws.

How to Fix Ez Debug LED Boot

Check the storage devices connected via the SATA ports. Remove the SATA cable from the motherboard and storage device. Then plug it back, ensuring that it fits properly. If it does not work, try using a different port. You could even work with a different cable.

You can also try out a new storage device entirely.

5. Other Issues

Other options exist if all of the above fail to resolve the problem. You can start by resetting the BIOS. Once you are in the BIOS settings, update the BIOS. Reset any overclocking settings to the default. You should also check for the DRAM overclock settings. Reset it to default.
