If you’re having trouble with your computer, one potential cause could be that there are no lights on your motherboard.
This can be a frustrating problem, but fortunately, there are some steps you can take to troubleshoot and fix it.
In this article, we’ll go over what to do if you’re having this issue and how to get your computer back up and running.
Step 1: Check the Power Supply
The first thing you should do if you’re having this issue is to check the power supply.
Make sure that it is plugged in and turned on, and that all of the cables are properly connected. If you’re using a desktop computer, the power supply is typically located in the back of the case.
If you’re using a laptop, it’s usually located on the side or the back of the machine.

Step 2: Check the Motherboard
Next, you’ll need to check the motherboard itself. Make sure that all of the cables are securely connected and that there are no loose connections. You should also check to see if there are any bent pins on the motherboard, as these can cause problems.
If you’re not sure how to do this, you can refer to the manual that came with your motherboard or search online for more detailed instructions.
Step 3: Try a Different Power Supply
If you’ve checked the power supply and the motherboard and everything seems to be in order, but you’re still not getting any lights on the motherboard, you may need to try a different power supply.
This can be a bit more complicated, especially if you’re using a laptop, but it’s worth a try if all else fails. If you’re using a desktop computer, you can just swap out the power supply for a new one.
If you’re using a laptop, you may need to take it to a professional to have the power supply replaced.

Step 4: Check the BIOS Settings
Another potential cause of this issue could be a problem with the BIOS settings.
The BIOS (basic input/output system) controls the basic functions of your computer, and if it’s not working properly, it could prevent the lights on the motherboard from turning on.
To check the BIOS settings, you’ll need to restart your computer and enter the BIOS setup utility. This is usually done by pressing a key (such as DEL or F2) during the boot process.
Once you’re in the BIOS, you can check the settings and see if anything is amiss.
Causes Of No Lights On A Motherboard
There are several potential causes for no lights on a motherboard. Here are some of the most common ones:
- Power supply issue: If the power supply is not working properly, it can prevent the lights on the motherboard from turning on. This can happen if the power supply is not plugged in or turned on, if the cables are loose or disconnected, or if the power supply itself is faulty.
- Motherboard issue: If the motherboard itself is not functioning properly, it can also prevent the lights from turning on. This can happen if the motherboard is damaged, if there are loose connections, or if there are bent pins on the motherboard.
- BIOS issue: The BIOS (basic input/output system) controls the basic functions of your computer, and if it’s not working properly, it can prevent the lights on the motherboard from turning on. This can happen if the BIOS settings are incorrect, if the BIOS is outdated, or if there is a problem with the BIOS itself.
- Faulty components: In some cases, the problem could be caused by a faulty component on the motherboard, such as the CPU, the RAM, or the GPU. This can be difficult to diagnose and fix, and it may require the help of a professional.
- External factors: Finally, the problem could be caused by external factors, such as a power surge or a sudden drop in power. This can damage the motherboard and prevent the lights from turning on. To protect against this, it’s a good idea to use a surge protector and to avoid using your computer during storms or other times when the power is unstable.
Should You Replace A Motherboard With No LIghts?
In most cases, if you’re experiencing no lights on the motherboard, you should not replace the motherboard right away.
Instead, you should try to troubleshoot and fix the problem using the steps outlined in the previous answer.
This can save you time and money, as replacing the motherboard is a more complex and costly process.
However, if you’ve tried all of the troubleshooting steps and you’re still not getting any lights on the motherboard, it may be time to consider replacing it.
In this case, it’s a good idea to consult with a professional to determine the best course of action. They can help you diagnose the problem and recommend the best solution, whether that’s replacing the motherboard or trying a different approach.
Final Thoughts
If you’re having trouble with your computer and there are no lights on the motherboard, don’t panic.
There are steps you can take to troubleshoot and fix the problem. Start by checking the power supply and the motherboard, and make sure all of the cables are securely connected.
If that doesn’t work, try a different power supply or check the BIOS settings.
With a little bit of patience and perseverance, you should be able to get your computer back up and running in no time.
