Some motherboards have light indicators, while some do not have, although this is due to the wide range of manufacturers and models.
Fast diagnostics may be accomplished with various color options, including several indication lights and entire displays. So, what does a yellow light on motherboard mean?
The different motherboard manufacturers have their manual guides and describe the several colored lights as various indicators. But most of them described yellow light as the indicator of the DRAM error. Also, we always suggest reading the user manual given with the box.
Read and learn about the yellow light errors on your PC’s motherboard and ways to solve all the errors.
Also, you will find other errors like blue, green, or red light indications with their probable solutions.
DRAM Failure & Yellow Light On Motherboard
When you detect a light on your motherboard, you should check to see whether the light is on all the time or if it is flashing.
The presence of a static or flickering light on your motherboard is not always a sign of malfunction. In the event of a Dell computer problem, it might assist you in narrowing down the source.
As we have explained, when the yellow light comes on, you know there’s a problem with the DRAM.
On the other hand, a solid orange light may signal a problem with the motherboard on particular motherboards. A malfunctioning power supply will make the orange light on your motherboard flash.
If the motherboard’s VGA light is on, the GPU isn’t being detected (Graphics Card). A loose connection is a common cause of this.
Let’s explore why there should be a DRAM failure on your motherboard.
Installing your new RAM is more likely to cause your computer not to recognize it than the modules themselves.
Each RAM stick must be placed in its memory bay, and the operating system must accept the quantity of memory you have inserted.
On 32-bit Windows, there is a limit of 4GB of RAM; however, on 64-bit Windows, there is a maximum of 512GB of RAM.
Arrived Dead On Time
Although RAM manufacturers guarantee their craftsmanship, completed products may have material flaws.
It’s improbable, but not impossible, that you’ll find a problem with a RAM module shortly after you buy it because of quality assurance testing.
The vast majority of RAM manufacturers will replace damaged memory.
Mistakes That Are Difficult To Solve
“Hard errors” are caused by physical damage to memory cells, which may lead to hardware or software failures when the memory cells are accessed.
Hard drive mistakes, unlike soft errors, cannot be corrected. This might be due to excessive temperatures in the RAM, a bad installation, incompatibility, or power cord surges. Cisco says that these can all cause complex faults.
Various factors like heat, magnetic interference, electrostatic discharge, power surges, and faults so minute that they pass quality assurance testing may cause “soft mistakes” in RAM modules. According to Cisco, these “soft errors” might occur.
Soft mistakes may cause read and write issues and even crashes, although memory checks or reboots may fix them.
According to Dell, a “hard error” caused by two “soft faults” in the same memory cell might lead to physical corruption.
Diagnostics Of Hardware For Yellow Light On Motherboard
Hardware diagnostic utilities and other tools for hardware evaluation are preinstalled on the vast majority of computers.
- The hard disk of most PCs comes preinstalled with software called 32-bit Diagnostics. Running the tests:
- Restart the computer to get everything back to normal.
- When the Dell logo screen shows, hit F12 on the keyboard.
- To access the Boot to Utility Partition or Diagnostics menu, press Enter after selecting the option on the Boot menu.
- To bring up the Test System menu, use the Tab key and Enter.
- In 10-20 minutes, an Express Test will conduct a brief test.
- It may take up to an hour or more to finish the Extended Test, which runs a comprehensive system check.
- A gadget may be tested using Custom Test.
- A symptom tree enables you to choose tests based on the most frequent symptoms.
Troubleshooting A Faulty Motherboard That Displays A Yellow Light
Process-1: The Cmos Can Be Cleared
- Unplug the PC’s power cable and shut off the machine.
- Disconnect the motherboard’s flat, COIN-sized battery.
- To restart your computer, press the computer’s power button for 30 seconds three times.
- Check what happens when you reinstall the CMOS battery and turn the PC back on.
- The BIOS settings are restored to their default state if the CMOS battery is cleared.
- The CMOS battery is in charge of the motherboard’s settings, such as the date and time.
- If you have a voltage meter, you may also check the voltage of the CMOS battery. 3 volts is about right.
Process-2: Replace the RAM Modules
- Try switching from A1, A2 to A1, B1 if you have dual-channel RAM sticks.
- Access panels on particular laptops allow you to switch out RAM modules.
- Some computers have a few RAM slots accessible via an access panel, while others are hidden away.
- To upgrade the RAM on particular laptops, you’ll have to take the machine apart.
Process-3: The RAM stick should be left out
Use only one RAM stick if you have access to two or four slots for RAM sticks.
Process-4: Try a different memory stick
It’s possible to attempt a RAM swap if you have another stick of RAM available. That way, you can verify that your RAM slot stick is functioning correctly. Afterward, check for dirt on all three components (RAM stick, ram connections, and the motherboard plug). There may be much dust to be cleaned up.
Some Other Light Signal And Their Solutions
Orange Light On Motherboard
An orange light on your motherboard might indicate a variety of different problems.
Static or flickering blinking patterns have diverse meanings depending on the user.
There is a good chance that either the motherboard or a memory issue is blamed for a steady orange light.
On the other hand, if you see a flashing orange light on your computer’s power supply, you may have an issue. What can you do about these issues?
What To Do If The Orange Light Is Static?
In the event of a static orange light on your motherboard, you must properly analyze the system since there might be several reasons for it.
In most cases, it’s an issue with a storage device like an HDD or an SSD. It’s always a good idea to inspect your computer before making any selections.
Disconnect all of the system’s cords to the hard disks and optical drive to figure out what’s wrong.
Connect the PC’s power supplies to the motherboard and power it on afterward.
Try connecting each piece of hardware one at a time to observe which one lights up the motherboard orange.
Consider removing and cleaning the RAM’s pins if the problem persists.
Solution For The Orange Blinking Light
You may have an issue with your power supply if your motherboard’s orange light is flickering and the fans aren’t working.
Then make sure your power supply delivers the proper voltage to your system.
If the voltage is not enough, your power supply may need to be checked further using a paper clip or PSU jumper.
Red Light On Motherboard
Each motherboard LED Light informs you where the issue is, but it doesn’t necessarily tell you what the problem is either.
The red light next to the CPU label indicates a problem with the processor, which is one of the most prevalent causes of the red light.
Here are a few reasons why the CPU meter might go into overdrive:
- A problem with the CPU you’ve just installed.
- Because the CPU fan wire isn’t fully connected, it isn’t working correctly.
- The CMOS battery has run out of power.
- It could be that the pins are bent, which could indicate a problem with how it’s being plugged in, or that it hasn’t been appropriately positioned.
- Alternatively, the motherboard’s power cable might be plugged in incorrectly.
How to Fix a Motherboard’s Red Light Problems
All motherboards, including older ones without labeled, blinking red light indications, may use these instructions.
- Before removing or reconnecting any internal hardware, ensure the computer’s power is off and the power supply switch is set to 0.
- Reconnect and reseat any faulty hardware to make sure it’s working correctly.
- This step may be omitted if your board is older.
- Your motherboard’s bios should be reset.
- Plugging in a jumper is the most common way to short a jumper.
- Remove the CMOS battery and let it sit for at least five minutes as an alternative.
Solutions Of Red Light Errors In Some Other Cases
The red LED warning of a dead battery might make you want to rip out your hair. You may even want to give this a go first before moving on to other options.
If you can’t get your computer to work, disconnect and unplug all components, beginning with any hard drive bay, RAM, and the CPU. Verify that none of the pins or connections are damaged or obstructed.
A single RAM module may be left plugged in while the others are unplugged on the thermal pad.
You’ve probably located the issue if the computer seems to start and there is no red light present, even if there is no visual.
Green Light On Motherboard
A green light indicates the computer’s “hot” status as a safety measure. The motherboard light acts as a warning, even if it isn’t constantly green.
Make sure you have a green light on your motherboard to ensure it’s getting electricity. Make sure that your PC is receiving electricity as well. Remove your side panel and check the power indicator light inside to see what’s going on.
Solutions To Motherboard Errors With The Green Light
Try reseating the RAM modules. Once the DIMM slot has been blown out, firmly reinstall each RAM stick one at a time and continue the process with the remaining RAM sticks. Check for loose connections by unplugging and replugging each power supply ribbon cable connector.
Faulty Motherboard Symptoms and Signs
When a motherboard fails, there are several indications, including:
Bending Of The Motherboard
When you open your PC’s case, a bent motherboard from different causes, such as overheating or physical damage, might harm your system board. Mechanical stress or heat shock may cause cracks in PCB boards for personal information.
A Faulty Boot
As soon as you push the power supply unit, you’re left with a blank screen on your laptop or PC. Your motherboard may be at blame for this.
Motherboard Emitting A Bad Smell
If you notice a burning smell coming from your laptop or PC, this might indicate problems with the motherboard. In the case of PCs, the motherboard is the source of the open CPU enclosure and its appearance and feel.
Slow Down Performance
Your PC’s performance may suffer if your motherboard is too old or shows blue light and white light on the AC power connector. Your computer may take a while to start up.
Not Receiving Adequate Power Or Data
If your motherboard isn’t delivering enough power and data to the different components of your computer, your CPU and motherboard-attached fans may slow down.
Blue Screen Of Death
A blue screen with failed messages and error codes when you start your PC indicates that numerous components, including RAM, HDD, and the motherboard, may malfunction. Certain motherboard manufacturers also display the root cause of a problem.
Inappropriate Cpu Shutdown
Occasionally, your computer may unexpectedly shut down due to a lack of electricity from the motherboard to the many hooked components.
