Motherboards Red Light + No Display
Motherboards have a red LED light on them that is used as warning signals to the user. The Motherboards can have one or multiple lights on board to warn the user about hardware failure. These lights turn red when some hardware is not connected correctly or gets corrupted.
The old motherboards used to have one light on them, and the user had to look into all the hardware to see the problem. This was hectic; a solution was needed because if the system doesn’t start and the red light turns on, indicating that there is a problem with the hardware. Still, to find out the problem, required to look through all the computer components to find out the actual problem in the PC.
Now the modern motherboards have more than one red light on them. They have a light indicator for CPU, RAM, GPU, or the Boot. These multiple indicators have made it very easy for the user to find out the problem and deal with it. This helps if the computer doesn’t turn on, then the user can look inside the case and quickly find out which hardware component is causing the problem and then can deal with it accordingly. This can save all the time one will waste in finding the problem all by himself.
Now we will discuss all of these different indicators individually to find out their meanings and what problems can cause these red lights to turn on.
CPU Red light
The CPU light on the motherboard turns on when there is a problem with your processor. The processor is like your computer’s brain, and your computer won’t turn on if there is a problem with the processor.
The red CPU light on the motherboard can be caused by any problem related to the CPU. The CPU can be lost from the socket, or the fan over the processor can be a malfunction that can be causing the CPU indicator to glow.
The indicator turns red when the CPU fan is not connected correctly or is malfunctioning. It is because the CPU creates a lot of heat while working, and if the fan is not working correctly, it can cause severe damage. Another reason for the CPU red light to turn on can be the empty CMOS battery. The CMOS battery can cause problems while turning on the computer if it is not charged, and this problem will cause the CPU red light to turn on. These were the problems related to the red CPU LED light on the motherboard that can cause it to glow.
DRAM Red light
There is also a red light on the motherboard near RAM. This red light is the RAM indicator showing that there is some problem with the Random Cases Memory of the PC. PC doesn’t turn on when there is a problem with the motherboard and shows red light on the motherboard.
The problem can be caused by a lose RAM or a corrupted one. The problem can be easily solved by taking out the RAM and then putting it back into the slot. Push the RAM into the RAM slot until the clamps click on and properly enclose the RAM inside. IF the clamps don’t click, it means that the RAM is not locked correctly, which can cause the problem again. If the RAM properly gets locked in and still you get a blinking red light on the motherboard and no display or the PC doesn’t turn on, then the RAM can be corrupted, and you need to remove the corrupt RAM.

The glowing GPU or VGA red light on the motherboard indicates that there is some problem with the video card inserted in the motherboard. Either the card is corrupted, or it is not correctly plugged in.
The lit red LED light on the motherboard near GPU can be caused by loose power connectors of the video card or video card itself. This will also cause a lit red LED light on the motherboard and no display on the PC. Check the power connectors and again plug in the video card to resolve the problem.
The LED light for the boot is lit when the system cannot find the boot device. A corrupt or loose boot device can be the reason for the red light on the motherboard to glow.
A boot device is the storage device where the PC’s operating system is located, or if we make it easy for you, this is where the window of the PC is stored. To resolve this, check the power connectors and the device’s plugs to see if they are loose. Once they are correctly connected, turn on the PC again. If the problem persists, then the storage device can be corrupt.
How to fix the red light on the motherboard?
It is a problem that all PC users can face; above, we have defined the red LED light on the Motherboard and also given the precis solutions to the issues related to each red LED light on the Motherboard.
We will give a detailed solution to the problem and show you how to get your PC back from the dead when only these red LED lights are turned on and no display on the monitor.

If you have a red LED light glowing on your Motherboard and have no display, start resetting the BIOS. However, BIOS can be reset by removing the CMOS battery from the Motherboard. The Motherboard has a CMOS battery; turn off the computer and take out that battery for 3 minutes. Put the battery back in and turn on the system; if still, it doesn’t give the display, move to the next step.
As we said earlier, the red LED light can be turned on due to an empty CMOS battery. Try replacing the old battery with the new one and try to turn the computer on. If you still get the CPU light red on the Motherboard, try moving to the next step. If you want to replace the CMOS battery checkout.
If you still get lit red lights on the Motherboard after resetting the BIOS and replacing the CMOS battery. Try removing all the hardware from the Motherboard. Unplug every attached component from the Motherboard and thoroughly check each connector and socket.
Try cleaning the Motherboard thoroughly so that any dust or dirt that might cause the glowing Motherboard LED lights should be removed. For cleaning motherboards safely, refer to our article How to Clean Motherboard?
Check every plug and socket; if there is any missing pin or bent pin, try using a small screwdriver or any other metal tool to correct its position. After giving a thorough and in-depth check to all the connectors, plug everything back together and turn off the PC. If the problem is not solved and the Motherboard still has a lit LED light with no display, move to the next step.
The problem is not resolving the three might be corrupted hardware that might be causing this problem. Please start with the RAM and move on to the other hardware components to check which of them has a problem.
If you have more than one RAM on your Motherboard, try using the RAMs one by one to boot the PC. Try 1st, then 2nd, 3rd, and 4th. If the PC doesn’t show display on any one of them, borrow a RAM from some friend and try boot. If the system turns on, all your RAMs are busted. The computer still doesn’t turn on and move to the next component.
Remove the GPU card from your computer and try to turn on the PC without any GPU. If the Motherboard processor doesn’t have integrated graphics, borrow a working GPU, and boot the PC. If the PC starts and gives display well enough, or else move to the next device.
Storage devises Check
If your system is not giving any display, try booting by using a borrowed storage device, or if you have more than one storage device, try turning the system on by using them alternatively and see if it works. If still, you get no luck, go to the final step.
Disconnect External connectors:
For the last step in resolving the problem, remove all the external connectors connected to the PC. Remove your keyboard, mouse, speakers, or any other external device or cable connected to the PC. Let the power cable and display cable be connected to the PC. Could you turn it on and see? If the PC starts to boot, then start connecting all the wires and devices to see which one is faulty. Remove and enjoy your PC.
If your PC is still not working, then it means that now the matter is out of hand. Try using professionals to help with your PC or buy a new one for yourself.
