Faulty Or Damaged Motherboard
One possible reason is that the faulty or damaged motherboard cannot properly manage and distribute power to the various components of the computer system.
This can result in insufficient power being supplied to the components, triggering an orange light. Additionally, a faulty or damaged motherboard can also cause other components to malfunction or fail.For example, if the motherboard’s memory controller is damaged, it may cause RAM to fail or malfunction, triggering an orange light. Similarly, a damaged motherboard can cause other components, such as the graphics card or hard drive to fail, which can also cause an orange light to appear.
Overheating of hardware components can trigger an orange light. This is because when a hardware component gets too hot, it can malfunction or even fail entirely. Overheating can be caused by various factors.
Insufficient cooling can occur if there are not enough fans in the computer case or the existing fans are not functioning properly.
Dust buildup can also contribute to overheating. Over time, dust can accumulate on hardware components and impede airflow through the computer case. This can cause the components to heat up more quickly and trigger the orange light. Finally, a malfunctioning fan can also cause overheating.
BIOS or UEFI firmware is responsible for initializing the hardware components of a computer and loading the operating system. If there is an issue with the firmware, it can cause the computer to malfunction or fail to boot up properly.
Common causes of BIOS/UEFI issues include outdated firmware, corrupted settings, or failed updates. Outdated firmware may not support newer hardware components, leading to compatibility issues.
Loose Connection Between Components
A loose connection between components such as the power supply, RAM, or graphics card can cause an orange light. This is because the motherboard cannot properly manage and distribute power to the components due to the loose connection.
That results in insufficient power being supplied to the components, triggering an orange light. It’s important to ensure that all components are properly seated and connected to the motherboard to prevent loose connections and potential issues such as an orange light.
Troubleshooting An Orange Light On Motherboard
Here are some steps to troubleshoot and resolve the issue of the orange light.
Check Power Supply
The power supply is the first thing to check when troubleshooting an orange light. Begin by checking the power supply cable that connects to the motherboard. Ensure the cable is properly connected to the motherboard and the power supply.

A loose connection between components can cause an insufficient power supply, resulting in an orange light problem. One important component to inspect is the RAM. If the RAM module is not properly seated in its slot, it can cause a loose connection between the RAM and the motherboard, resulting in an orange light.
To inspect the RAM, turn off the computer, unplug the power supply, and open the case. Locate the RAM modules and ensure they are properly seated in their slots. If the RAM is not seated correctly, gently press down on both sides of the module until it clicks into place.
Another component to inspect is the graphics card. If the graphics card is not properly connected to the motherboard, it can cause a loose connection and insufficient power supply to the graphics card, triggering an orange light. To inspect the graphics card, follow the same steps as inspecting the RAM.
Check For Overheating
Overheating is one of the common causes of orange light. Checking that all fans are working correctly is crucial in troubleshooting this problem. Make sure that the fans are clean, free from dust, and spinning properly. If a fan is not working correctly, it can cause the computer to overheat, resulting in an orange light. You can read our guide on how to clean PC fans for more help.
Using monitoring software is another effective way to check the temperature of the CPU and other components. The software can display the current temperature of each component and can sound an alarm if the temperature exceeds a set limit.
If the temperature is too high, it’s important to address the issue immediately by turning off the computer and allowing it to cool down. If the computer continues to overheat, it may be necessary to replace the cooling system or seek the help of a qualified technician. Furthermore, we also recommended reading our guides on lowering CPU and GPU temperature.
