The ASUS Motherboard comes with four red LED lights on the motherboard. These LED lights are used to warn the user about hardware failure. There are multiple lights that turn red when some hardware is not connected properly or becomes corrupted.

In the past most motherboards used to have only one red light, which made it very difficult to find out where the problem was.

Thus, the ASUS motherboard manufacturer and other motherboard manufacturers have designed a better motherboard with more red lights on it making it very easier to know where the problem is.

This makes it simple and also saves time in fixing problems. This would be of immense help to troubleshooters working in PC shops as they will not have to waste time finding out what went wrong.”

There are many different indicators on modern motherboards. Let’s go through a few of them and see what they mean, and what problems can cause them to come on.

CPU Red Light

The motherboard CPU red light on the motherboard can be a warning sign that there is a problem with your computer’s processor. The processor controls your computer by acting as its brain.

If there is any problem with the processor, then it will not turn on, and this warning light will come on to show you that there is an issue.

If you have a red CPU LED light on the motherboard, don’t worry! The red light doesn’t mean that your computer is broken. If your CPU fan connection is not correct or it has malfunctioned, it will cause that LED to glow red.

Also, if the CMOS battery is not charged or empty, then there are chances of the red light turning on. The red light will tell you the reason for the problem and you can easily resolve it.

The indicator usually glows because of the processor fan, which helps in cooling it down and removing heat. This can occur if the components in your PC stop working continuously. There may be some confusion with regard to the Processor fan assembly because it refers to all the components that are required for keeping your processor cool.

RAM Red Light

When there is a red light on the motherboard by the RAM, it is signaling a problem with the Random Access Memory on the computer. This could be because the RAM is faulty or not connected properly.

What causes the problem sometimes is a lost RAM or missing RAM which can easily be solved by taking out the RAM and putting it back into the slot and pushing the RAM into the slot until the clamps click on and properly enclose the RAM inside.

If this doesn’t solve your problem or there is no display with sound, or the PC doesn’t turn on, then the problem can be caused by corrupted RAM, you need to remove the corrupt RAM for an upgrade.

GPU Red Light

The GPU red light on the motherboard means that there are some issues with the video card being inserted into the motherboard. Either the card is wrongly inserted or corrupted.

The glowing GPU red light can be a result of loose power connectors of the video card or the video card itself. This will also result in red light on your motherboard, and no display on your PC screen. Check if the power connection of your GPU is secure, and then plug in your video card to resolve the issue.

Boot Red Light

If a small red light is on your motherboard when you start it, it means the system can’t find the boot device. The boot device is where the operating system resides and loads.

A loose connection or bad device will cause the light to glow red. If this happens, check for plugs that are not connected properly, or if there is poor contact between any of the plugs and their sockets.
