  • BOOT: This code indicates any issues related to your system’s boot process. It could be due to an incorrect BIOS setting, a broken hard drive connection, or a damaged operating system file.

By understanding what the codes mean, you can easily pinpoint the source of any hardware issues and take steps to fix them. EZ Debug LED can save you time and money, so make sure to check it first if your PC isn’t working properly.

How To Fix EZ Debug LED?

If you are having issues with your EZ Debug LED, there are several methods that you can use to try and identify and repair the issue.

1. CPU

You should start your investigation by checking the CPU. Ensure it is properly seated in its socket and securely connected to the motherboard. You should also check the CPU heat sink and fan are securely installed, as this could cause the EZ Debug LED to light up if not properly seated. This could be due to poor contact with the processor or a damaged fan.

The 8 or 4-pin CPU power connector should also be checked to ensure it is properly connected. If the connection is loose or not seated correctly, this could cause issues with the CPU and trigger the EZ Debug LED. Also, you need to check the possibility of any bent or broken pin in the CPU socket. If you find two pins bent, you can use a needle or tweezers to straighten them.


Any obstruction of the DRAM is a possible cause for an EZ Debug LED. To fix this, ensure that all your RAM modules are firmly inserted into the RAM slots and that no dust, dirt, or other obstructions are present. If the issue persists, try a different set of DRAM sticks on your PC to check if the issue is with one of the RAM modules.

If this resolves the issue, the faulty RAM module needs to be replaced. You can also clear the CMOS to reset any DRAM configuration settings that may have caused the issue. Finally, ensure that your BIOS is updated with the latest version to ensure that all DRAM settings are compatible with your system.

All these steps should help alleviate any potential DRAM-related issues causing the EZ Debug LED to light up. Suppose these solutions do not resolve your issue. In that case, it is recommended to seek professional help from a PC technician who can identify and fix the underlying cause of your EZ Debug LED.

3. VGA

If your EZ Debug LED displays errors, a simple switch in the VGA cable could very well be the answer. Ensure that it’s securely connected to both ends of the device and if so, try switching out its current cable for one better suited to support higher-resolution monitors.

If this doesn’t resolve the issue, opt for an even more reliable alternative with improved quality.

If you use the graphics card in a laptop, check if the connections are secure and firmly connected. Using an external display, use the appropriate display cable and check the connections. The PCIe slot might also be loose, so check that as well.


A loose connection on your storage devices can be why a debug LED appears on your motherboard. To check this:

  • Open the computer case and take out all drives, including RAM and other peripheral devices.
  • Plug them back in and secure them with screws, so they’re correctly connected. If you have a SATA power cable, ensure it’s also connected to the drive.
  • Once this is done, boot up your PC and check if the debug LED is still on.

If not, then you know that the problem was with your storage devices.

5. Other Issues

If the above solutions do not help, check if the power supply and all its cables are firmly connected to your motherboard. Ensure all switches on the case and motherboard are in the correct position. Also, ensure that all connectors from the power supply and the case to the motherboard are connected correctly.

You can also try to reset the BIOS by pressing the reset button on the motherboard or simply unplugging and replugging the power cable.

If none of these solutions work, you may need to take your PC to a technician and have them diagnose the issue. A technician can identify any underlying issues that cannot be fixed with basic troubleshooting. They can offer other solutions, such as replacing faulty components or upgrading the system.
