Common LED Codes for GA-990FX-Gaming Motherboard Troubleshooting

LED codes are useful indicators for troubleshooting motherboard issues. They provide valuable insights into the specific problem affecting the system, helping users diagnose and resolve the issue quickly. If you own the GA-990FX-Gaming motherboard and are struggling with certain LED codes, this article will guide you through some of the most common ones encountered during troubleshooting.

01 - Power On

This LED code indicates that the motherboard is receiving power and is ready to start the boot process. If you encounter this code and your system fails to proceed to the next stage, it might be an issue with the CPU or memory.

02 - Memory Initialization

When this code appears, it means the motherboard is currently initializing the memory modules. If the LED remains at this stage for an extended period or doesn't progress further, it could indicate a problem with the RAM or its installation.

03 - Initialize VGA

This code signifies that the motherboard is initializing the graphics card. However, if the system gets stuck at this stage or fails to proceed, it could indicate a problem with the graphics card or its connection to the motherboard.

04 - PCH Initialization

PCH (Platform Controller Hub) initialization is indicated by this LED code. If the motherboard stays at this stage without progressing, it suggests a problem with the PCH or its related components.

05 - Reserved

This LED code is reserved for future use and does not have a specific troubleshooting significance at the moment.

06 - Microcode Loading

When this code appears, it means the motherboard is loading the microcode for the processor. If the system fails to proceed from this stage, it could signal an issue with the BIOS or the processor itself.

07 - PCH Initialization

This code indicates the second stage of PCH initialization. If the system hangs at this point, there might be an issue with the PCH or its related components.

08 - Reserved

Similar to code 05, this LED code is currently reserved for future use and doesn't have a specific troubleshooting relevance.

09 - OEM Initialization

At this stage, the motherboard begins the initialization process of OEM-specific devices. If any issues arise during this phase, it could be due to compatibility problems or faulty OEM devices connected to the motherboard.

0A - Pre-memory CPU initialization

This code signifies that the motherboard is conducting pre-memory initialization of the CPU. If the system doesn't progress beyond this point or seems stuck, it may indicate a problem with the CPU or its installation.

0B - Initialize USB controllers

During this LED code, the motherboard initializes the USB controllers on the system. If the system fails to proceed from this point, it suggests an issue with the USB controllers or their connection to the motherboard.

These are some of the common LED codes encountered during troubleshooting with a GA-990FX-Gaming motherboard. By identifying the specific code displayed during startup, users can gain insight into the underlying issue affecting their system's functionality. If you encounter any of these codes or similar ones, refer to your motherboard's manual or contact technical support for further assistance in resolving the problem.
