Nevertheless, whenever you take the suitable steps, troubleshooting the crimson gentle in your motherboard is surprisingly easy.
Why Does the Motherboard Purple Error Gentle Seem?
The crimson LED in your motherboard might illuminate for a couple of causes. It usually seems as a result of cables aren’t related correctly, or there is a matter with the {hardware} configuration. Typically, motherboards have a number of crimson lights seated beside useful labels.
In case your motherboard has these labels, troubleshooting is quicker however not all the time as fast as you’d suppose. In any other case, you need to have the ability to resolve the problem by generalized troubleshooting.
How you can Repair the Purple Error Gentle on a Motherboard
As with all different troubleshooting course of, the best solution to begin is with the best steps.

Examine if the Purple Gentle Has a Label
Earlier than taking another troubleshooting steps, you need to examine whether or not the crimson gentle in your motherboard is labeled. Most fashionable motherboards have 4 crimson LEDs labeled CPU, DRAM, BOOT, and VGA. Relying in your kind of motherboard and what LED is illuminated, you’ll be able to slim the attainable troubleshooting steps required right down to a manageable choice.
The LED that mostly illuminates is the CPU gentle. It should seem if POST detects any difficulty associated to your CPU, together with however not restricted to compatibility points and improper installations. Doable causes of an illuminated CPU gentle embody:
- Your BIOS model is older than your CPU and must be up to date.
- Your CPU is incompatible together with your motherboard (examine the motherboard QVL).
- Your CPU wasn’t correctly put in, or the CPU has bent pins.
- The cables to your CPU aren’t correctly related.
- Thermal paste smudged into areas the place it would not belong.
- Your CPU is lifeless or defective.
Much less generally, the DRAM gentle illuminates. This gentle signifies that there is one thing flawed together with your RAM. Doable causes of an illuminated DRAM gentle embody:
- Your RAM sticks aren’t correctly seated.
- The RAM sticks you are utilizing are incompatible with each other.
- Your RAM sticks are incompatible together with your motherboard (examine the motherboard QVL).
- The clamps holding your RAM in place did not correctly click on into place.
- Your RAM sticks could also be defective or broken (attempt testing one after the other).
- Your CPU pins could also be bent (inexplicably, this could trigger the DRAM gentle to light up).
You may additionally discover that the BOOT gentle is illuminated in your motherboard. You’ll be able to safely assume that your HDD/SSD is the reason for this indicator. There are a couple of causes that the BOOT gentle might illuminate, together with:
- You don’t have any working system put in.
- The HDD/SSD shouldn’t be correctly seated or related.
- The SATA port the HDD/SSD is related to is defective or disabled.
- Your PC is trying as well from certainly one of your non-bootable HDD/SSDs.
- Your HDD/SSD is lifeless or corrupted.
- BIOS can’t detect your HDD/SSD.
- Your motherboard doesn’t help your HDD/SSD kind or interface protocol.
The rarest error gentle to light up is the VGA gentle. Just like the CPU gentle, the VGA gentle illuminates when POST detects an issue together with your graphics card. Doable causes that the VGA gentle might illuminate embody:
- The GPU or PSU energy cables are improperly related.
- The PCIe socket latch on the GPU did not click on into place.
- The GPU shouldn’t be put in within the right slot, or the GPU or PCIe slot is broken.
As you’ll be able to see, though the motherboard crimson gentle error is an effective place to begin, it would not all the time specify the motherboard error—so extra troubleshooting is required.
Confirm That Cables Are Correctly Plugged In
If the earlier troubleshooting steps did not work—or in case your motherboard is an older mannequin with just one unlabeled crimson LED—you will must take broader, generalized steps to find out what is likely to be flawed. If you have not already, attempt unplugging and reconnecting any cables to the motherboard or its put in elements.
Examine if Your {Hardware} Is Appropriate
If the connections weren’t the wrongdoer, the problem is likely to be that your {hardware} is incompatible. Be sure that your motherboard, HDD/SSD, RAM, GPU, CPU, and PSU are all suitable. There are a couple of methods which you can examine your {hardware} compatibility, however the easiest way entails utilizing a web site like BuildMyPC, PC Half Picker, or NewEgg’s PC Builder. It’s also possible to use your motherboard’s QVL to examine compatibility.
Reset the Motherboard BIOS
In some instances, defective configurations could cause the motherboard’s crimson gentle to light up. This difficulty is especially widespread with unstable overclocking configurations. If earlier troubleshooting strategies have failed, you’ll be able to attempt to revive your motherboard by resetting the BIOS to its default settings.

Lastly, exit BIOS, save your modifications, and examine whether or not the crimson gentle remains to be illuminated.
Remember that resetting your BIOS may also take away any BIOS updates put in. In case your CPU relied on a BIOS replace to perform correctly, you will must reinstall the BIOS replace earlier than your system will boot.
Alternatively, you’ll be able to reset BIOS by eradicating and reinstalling your CMOS battery.
Reseat Motherboard {Hardware} Parts
As improper connections could cause the crimson gentle in your motherboard to light up, it is also price verifying that every one {hardware} on the motherboard is seated correctly. Launch the tabs and take away the RAM, then reseat it. Join your PC to energy and examine whether or not the sunshine remains to be illuminated. You also needs to attempt reinstalling the CPU, HDD/SSD, GPU, and PSU.
Substitute the CMOS Battery
It is fairly widespread for a depleted CMOS battery to trigger the crimson gentle in your motherboard to light up. Generally, you’ll be able to rapidly exchange the CMOS battery by ordering and putting in a CR2032 battery—however make sure that to double-check that that is the correct kind. The placement of your CMOS battery depends upon your motherboard’s kind issue.
