[Fix] ASRock Motherboard Flashing Red Light (100% Working)

As all the important components such as RAM, PSU, GPU, HDD, SSD, and others are connected to the motherboard, there must be an indicator to detect issues with hardware.

Like every motherboard, ASRock also has an LED indicator to inform you about system faults. So, when the LED light of your ASRock motherboard blinks red, you should not ignore the sign.

Do you know what it means or what light indicates? If not then don’t worry, you can easily identify and fix the problem related to your ASRock motherboard after reading this guide. So, let’s read this article by the end without wasting any more time.

Why ASRock Motherboard Flashing Red Light?

There can be several reasons for an ASRock motherboard to flash red light. Basically, it indicates faults with the hardware. Here are some common reasons for that:

• Loose connection of CPU fan or broken CPU fan.
• The CPU hasn’t assembled properly.
• The pins of the processor are damaged.
• CPU or motherboard is overheating.
• The RAM hasn’t assembled correctly or is damaged.
• The GPU hasn’t assembled properly.
• Unable to Access Hardware During Start
• The Hard disk hasn’t connected properly or is damaged.
• The BIOS of the motherboard is corrupted.

Meaning of ASRock Motherboard Flashing Red Light | How to Determine Faults

The ASRock motherboard has 4 (four) indicator LED lights: BOOT, VGA, DRAM, and CPU. The red light on each of these LED lights indicates a different and specific issue with the motherboard.

Below is what each one means:

1. Red light on BOOT Indicator

If you see the red light on the BOOT indicator, that means there is something wrong with the boot devices on your ASRock motherboard. It mainly indicates the fault with the hard drive where the OS is installed.

2. Red light on VGA Indicator

If the red light is near the VGA indicator, that means the GPU or the graphics card is displaced or hasn’t been placed correctly. It also indicates a faulty GPU in the worst cases.

3. Red light on DRAM Indicator

If you see the red light at the DRAM (Dynamic random-access memory) indicator of your motherboard, then it means that your RAM is displaced or hasn’t been seated correctly. If you forget to lock the clips of the RAM slot after placing the RAM, then the red light will flash on the DRAM indicator.

4. Red light on CPU Indicator

If you see the red light at the CPU indicator, then it can be due to a few reasons. The possible reasons are:

• The CPU has not been plugged in correctly.
• The CPU fan is unplugged.
• The CMOS battery is dead.
• The power cables are not plugged in correctly to the motherboard.
• The CPU is defective.

How to Fix ASRock Motherboard Flashing Red Light Error?

As you know the reasons behind the flashing red light on each indicator of your ASRock motherboard, you can fix it by checking that specific hardware. If you are still not sure how to fix it, then follow the given instructions one by one until the issue resolves.

Warning: Do not connect or disconnect any hardware to the motherboards while the power is on!

Solution 1: Check the Faulty Hardware

Observe and identify in which indicator the red light is flashing. Then disconnect the affected hardware and reconnect it correctly. If you don’t have any option to remove the defective hardware, then skip this step and follow the next.

Solution 2: Reset the BIOS

Sometimes the problem with the BIOS causes red light on the ASRock motherboard. To fix it, you need to reset the BIOS. You can either check your manual to reset the BIOS or you can go to the official website of ASRock, select your motherboard and get the manual.

Alternatively, you can remove the CMOS battery and reconnect it after 5 minutes and your BIOS will automatically reset.

Solution 3: Replace CMOS Battery

A dead battery often triggers red light flashing on the ASRock motherboard. So, you need to replace the CMOS battery and check if the red light stopped flashing or not. If not, then try the next step below.

Solution 4: Remove External Peripherals

If none of the above solutions works, then remove all the external peripherals including mouse, keyboard, printer, ethernet cable, external hard drives, memory card, etc., and check if the issue resolves or not.

Solution 5: Reduce Overload

If you are using more than one GPU and RAM, then reboot your computer with a single stick of RAM and without any GPU. If that stops the red light, then try rebooting it with the GPU equipped. If the red light starts flashing again, then the GPU is faulty or incompatible with your motherboard.

But if no red-light flashes after rebooting the motherboard equipped with a single RAM stick and a GPU, then your ASRock motherboard won’t support that extra RAM that you have recently unplugged from your motherboard.

Solution 6: Check the Power Supply Unit

If none of the above solutions can fix the red-light flashing issue with your ASRock motherboard, then the fault is with the PSU of your computer. In that case, unplug and re-plug all the power cables of the motherboard. Especially, unplug the PSU and check if it working correctly or not.

After applying the above solutions, the red-light flashing issue with the ASRock motherboard should have been solved.
