When an issue arises in your system, you may notice the Motherboard indicator light flashing red. When components are missing or malfunctioning, the Motherboard will indicate this with a blinking red light.

However, Motherboard’s red light may appear for a variety of users in a wide range of situations. Some users may see a red light if there’s a hardware issue, while others may see a when there’s a memory issue.


Method 1: Get Any Broken or Affected Hardware Fixed or Replaced.

Red Light On Motherboard

This issue has been traced down mostly to a hardware malfunction. Therefore, you should first ensure there is no problem with the hardware. In order to get rid of the embedded dust on your motherboard, you must first clean it.

Then, meticulously check every piece of equipment. Also, make sure that there is no loose connection or damaged sockets by double checking all of the connectors and sockets.

If you suspect a hardware problem, you’ll need to unscrew everything, disconnect every cable, and reseat each piece of equipment individually until you find the offending piece.

To fix the current issue, check for broken or loose connections or sockets, and fix or replace them as necessary.

Method 2: Switch Out Or Reconnect the Power Cable.

A broken or poorly connected power cable is another possible source of the problem. This issue may arise if the cable connecting the device to the power source is damaged. The motherboard’s red light is on because the power cable is broken and can’t give enough juice to the board.

The use of regular or low-quality cable increases the risk of this happening. Therefore, if the power cable is determined to be at fault, a new or official cable should be tried to remedy the issue.

Method 3: Observe The PSU

The Power Supply Unit (PSU) is the housing for the motherboard’s power connectors and cables. Given that the power supply unit (PSU) is responsible for supplying electricity to the motherboard, its failure could result in the latter blinking a warning signal.

You could start by inspecting the power supply unit (PSU) if the issue persists after reconnecting all the power cables. Here are the steps to take to accomplish this:

  1. The casing can be opened by first removing all cables.
  2. Second, disconnect the motherboard and any other components from the power supply unit.
  3. After you’ve unscrewed the PSU, you can test its functionality by installing it in a different computer.
  4. Obtain a new power supply unit and install it in the system if the old one is faulty.

Method 4: The Reseat the Video Card And the Memory.

It has already been established that improper placement of the GPU and RAM could lead to this issue. Since your system might not notice if you put your GPU or RAM in the wrong position. As a result, you should double-check the secureness of your GPU and RAM.

If they are in the wrong places, rearranging them might help. If you have more than one RAM, make sure each one is working properly.

Follow this short guide to determine if your RAM is working properly:

  1. After turning off the power, open the system’s housing.
  2. Verify if the RAM slots are accessible by inspecting the Motherboard.
  3. Then, remove the memory modules from their slots.
  4. Afterward, use a soft cotton cloth or brush to wipe the RAM and the slots.
  5. When you’re done cleaning them, put them back in their respective slots in the correct order.

The red light problem can be tracked down if you check for resolution after each RAM installation.

Method 5: Reconnect Storage Drives

It is possible for the Motherboard to flash red if storage devices are causing problems. Because of this, you may end up with a red light problem if your solid-state drive (SSD) or hard disc drive (HDD) is not recognised by the motherboard.

To resolve this issue, ensure a solid connection between your motherboard and hard drive or solid-state drive. To achieve this, please refer to the procedures below.

  1. After unplugging the device from its power source, open the case.
  2. Then, disconnect the storage drive’s SATA cables.
  3. Use a clean, soft cotton cloth or brush to remove any remaining dust from the drive, then reconnect the drive’s connections securely to the SATA port.
  4. Last but not least, make sure the motherboard issue has been fixed.
