If you found Red Light on Motherboard, there may be two different issues, either you have wrongly unplugged the hardware, or the hardware is not working correctly. CPU, RAM, or graphic cards are counted in hardware. You can even blame the CMOS battery, which can be dead. The space where you install your primary OS check that part because this can happen that may be the red cpu light on motherboard is caused by boot problems. Check the issue correctly; you will see the red light on motherboard when you turn on your PC, so check the BIOS or monitor display setting for further information. If your motherboard has any of the above issues, your motherboard will signal by showing a red light; there are some motherboards with proper labeling that help you determine what’s wrong with your PC.

Red Light on Motherboard indications without any display:
The red light on motherboard means there is something wrong with your PC. Maybe the red light is the indication of any hardware issue or even worst than that. If any hardware gets corrupted or you didn’t plug it in the right, you will start to get red light cpu motherboard indications.
It was hard to find out what is wrong because of the single red light in older motherboards, but now there is a separate indication for different problems.
For example, if there is an issue with the hardware, your computer will not start, and you will only see the red light on the motherboard, so try to give the hardware a double check. But if still, you failed to determine the issue, you have to contact a professional hardware engineer.
Four different red cpu light indicators on the motherboard:
If we talk about red light, there are four different indicators it gives when seen on different parts of the motherboard. You will see the red light next to each label, so the reasons are given below:
Indications for Red light near the BOOT:
If you see red light near the boot, something is wrong with the BOOT, or the hard drive can be the reason. If we talk about the specific part, it can be at the hard drive where you store OS. This red light may be because any loose or even corrupt boot devices are connected to your PC.
Specifically, the boot device is responsible for keeping all the PC operating systems, or you can also say that boot is the device where the PC’s window is stored. You can easily solve this issue by taking some necessary steps, like checking device plugs. Make sure each of them is appropriately connected. After connecting all the plugs, restart your computer; if there is still an issue, then maybe your device may be corrupted. you may also love to read Best Motherboards for Ryzen 9 5950X
Red light near VGA or GPU:
If the graphics card is not inserted correctly or the motherboard can’t detect the card, then maybe you will see red light near VGA or GPU. You can say that the reason behind the triggered red light around the GPU may be because of a problem in your video card power connection or even in the card itself. Due to this, there will be no display on your PC and lighted red light indications from VGA or GPU. You can easily solve the issue by checking the power connection twice to confirm it’s correctly plugged in and then inserting the video card again.
What does Red light near DRAM mean?
If the RAM module is not inserted properly, you will see a red light indicator near DRAM. Probably the detailed issue can be with side clamps present on either side of the RAM stick. Apart from that, when the problem is with the motherboard, your PC will not switch on, and you will also see a bright red light on your motherboard.
Even you can say the main source of this issue is missing or damaged RAM. You can fix this issue by replacing or removing the RAM slot, try to push the RAM until you listen to a click sound; after that, the RAM will be completely enclosed.
If you didn’t hear a click sound, that means the RAM isn’t inserted correctly. This may cause a recurrence issue. If the RAM slot is inserted correctly, but the red light is still blinking, and there is no display on the screen of your computer, then you have to replace the RAM because maybe the RAM is contaminated.

What happened when you see Red light on the CPU?
The red light on the CPU indicator means the motherboard failed to recognize the CPU, and in this case, there are multiple reasons. As we all know that the CPU is the brain of your computer, so in case of any issue, your computer will not turn on. And you will start to get red light indications from the CPU.
Maybe you haven’t plugged in the CPU correctly, one of the CPU pins is bent, you haven’t plugged in the CPU fan, or even you will see a red light when the CMOS battery is dead.
The main function of the CPU fan is to through the heat generated by the CPU out of the computer, but when the fan stops working, this means the heat will remain inside and will cause a lot of severe damages.
In case of a CMOS battery issue, your computer will not start. This may be because the battery isn’t fully charged.
Red light because of hardware problems:
If none of the above-mentioned problems is related to your issue then surely one of your computer components needs to be replaced. Some of the basic components related to cpu red light on motherboard issues are listed below:
Problem with compatibility of your PC:
Having an issue with the compatibility of your PC is very rare if you double-check every component of your computer correctly. Then after that when you finally buy a computer for you make sure that the nearest tech store always guarantees that all the parts of your computer are compatible.
Your new system has broken parts?
After using a computer for a long time, you have to change some inevitable cogs of your computer. Using the same components for a lot of time can reduce or even quit working. The red light on the motherboard can be an indication that some of your computer component t has reached their end of life and needs replacement.
Maybe the BIOs setting is incorrect:
The red light on your motherboard can be an indication that the BIOs setting of your computer is somehow wrong. Because the first executes by your CPU is the input/output system after you push the start button. BIOs are also software responsible for data transfer between different operating systems.
Maybe the red light indication on your motherboard is because the setting of BIOs has been changed, and now your computer is not booting up correctly. To solve this issue, go through the motherboards manual settings, and check the instructions given with diagrams to reset the BIOs settings.
Another method to solve this issue is to remove the CMOS battery and put it again after five minutes. By doing this, you will clear all the BIOs input you have done wrong.
The issue with CMOS/BIOS battery:
The newly manufactured motherboards have a button control battery, real-time clocks with an onboard oscillator, and RTC. This is because when we turn off the computer, it continues to work to operate the oscillator and clock to see the correct time and date whenever we log in.
We shut down our computers, whether the old computer models use a bit of power to reserve the BIOS setting. Nowadays, the word CMOS is used for the area RAM having low power, in which CMOS chip is used. In this static RAM region, your Computer’s BIOS setting will be reserved no matter how many times you have opened your computer.
CMOS/BIOS battery is drained:
If you are still using an old model computer, it will surely need a battery to save and be up to date with your BIOS setting. However, when this battery is out of energy, your motherboard will start to give red light indications. And you will stop to get updated BIOS settings.
But always remember that a single CMOS battery lives up to ten years, depending on your usage. Apart from that, an onboard BIOS battery will only work when your computer is switched off. This means that the battery will last for years when you frequently use your computer.
Maybe your computer system is overheated:
You may start to see the red light on your motherboard when your computer system is overheated. You can check the heating level by taking out the side panels and check them around the CPU or graphic card.
Or even maybe the case is different, and the red light is because cooling components are broken or aren’t linked correctly. Moreover, some computer system gives you an alert when the computer system starts reaching its heating level.
Incorrect post check signals:
Sometimes the red light on the motherboard is because post-check signals are incorrectly in-built. The word POST stands for power-on-self-test, a system check type when you start your computer. This POST test analyzes whether CPU, DRAM, and hardware are working in sync and correctly or not.
If there is any issue, you will start getting loud, noisy text on your screen. If it didn’t happen, you would listen to a series of beeping sounds with red light. You can solve this issue by reading the motherboard handbook and figuring out what these beep noises and a red light mean.
How to fix the motherboard Red Light on Motherboard issues?
All the red light indicators on the motherboard I have mentioned above are very common. So below, we are going to mention some of the possible solutions to all the problems, so you don’t have to call the hardware engineer. These solutions will help you to give your PC a new life.
Reset your BIOS when you see the red light on motherboard:
If there is no display, and you see the red light on your motherboard, it’s time to reset your BIOS. You can reset the BIOS by simply removing the CMOS battery from the motherboard. Starts the process by switching off the computer, now remove the CMOS battery from about 3 minutes, after that place the battery again. You can start the system again; if you still didn’t see any display, move to the next step.
Time to replace CMOS when you see LED red light on motherboard:
If you see a red LED light on your motherboard, it’s probably because your CMOS battery is empty. Switch off your computer, replace the battery, and then power on. But if the red led motherboard is still giving you a red signal, further follow the next step.
Remove the hardware if you still see red light:
If there is still a red light after resetting the BIOS and replacing the CMOS, it’s time you have to remove all the hardware and try putting them again. Start by unplugging all the connected components from your computer and then plugging them again one by one. Concentrate on each socket that if any of them have a missing or deformed pin, try to reposition every component using a screwdriver. Now connect every plug again and switch off the PC. With careful inspection, move towards the next step if you still see a bright red light.

Time to check the RAM if nothing works:
If all the above methods failed to solve your issues, maybe the problem is with your hardware. To determine the exact problem, check all the hardware components but start by RAM.
Many computers have more than one RAM slot so boot your computer each time while checking the RAM. If you still didn’t see any display on your computer, borrow RAM from your friend, put it in, and then boot your computer to see if the problem is with your RAM or not. But if replacing the RAM didn’t work, check the GPU.
Remove and check the GPU:
If all the above methods failed to work for you, maybe the problem is with the graphics card. Remove the graphic card and then turn your computer without it. If your CPU didn’t have any graphic card, borrow it from somewhere and reboot your computer. After booting, if you see the display, you can move to the next step now.
Check the storage devices:
Borrow the storage device from someone and restart your computer. If you have more than one storage device, then turn them on one by one and see this method works for you or not. Are you still having trouble? Move on to the next step; maybe it will work.
Disconnect all external connectors:
Sometimes the problem is not with internal components; maybe the red light is because of external connectors. Start by removing all the external connectors, also remove the external devices, cables; on anything connected with your PC, even the keyboard, mouse, or speakers. And only connect the power and display cables. Now switch on the computer to see if the problem is solved. If your computer boots up normally, start connecting all the connectors again one by one and see which one is broken.
Any LED light, whether orange or Red Light on Motherboard, means there is no problem. The article above is about red light indications from different parts of the motherboard and their meaning. Moreover, from above, you will also have a solution without getting help from a hardware engineer.
