If you’re wondering what causes a yellow light on motherboard read on. This article will explore the most common causes. CMOS battery RAM CPU power supply and power cord are some of the most common culprits. If you still see this light there are a few other possible causes that you should investigate. In addition you should check for static shock or overheating issues. Once you’ve eliminated these potential problems your motherboard should continue to function properly.
Problems with the CMOS battery
If you experience problems with your computer clock it’s probably due to problems with your CMOS battery. These batteries fail as your computer ages and you should consider replacing them. They’re inexpensive and easy to replace. If you can’t find the CMOS battery you can look for the round lithium battery on your motherboard. To do so check the motherboard manual to see where it is. You can then follow the steps listed in the manual to replace the battery.
Before replacing the battery you should first check the voltage and type of the battery. Also check the time/date settings and the hardware of the PC. Make sure the CMOS battery matches the voltage and type of battery. The computer will not start if the battery is out. If you have any of these symptoms you should get it checked by a technician. You can try leaving the computer on overnight to charge it.
Problems with the RAM
If your computer is experiencing a slowdown you may be suffering from problems with the RAM. If you have ever had problems with RAM you should first understand what these beeps mean. The beep codes will depend on the manufacturer and the BIOS so you will need to research which one you have before taking any action. Fortunately there are a few ways you can fix RAM problems. Listed below are some simple steps to take.
First restart your computer. If the problem is in the memory module do not use your computer while the diagnostic process is running. Then go to the Event Viewer and look for the MemoryDiagnostics-Results event. This event will provide you with details and technical information. If the problem is not in the RAM you should contact the manufacturer of your computer. It may take several minutes for the system to detect the problem so be patient.
Problems with the power supply
If you’ve noticed your computer restarting and turning off during bootup it could be the power supply. It could also be the power fan which may be clogged. In such cases you can clean the fan by using a vacuum cleaner. Other possible problems include the computer not booting at all. To diagnose problems with the power supply you can use a power supply tester or a multimeter. If the power supply does give the correct voltages the issue may be in the power supply itself.
The power supply box may be hot or the fan may not be rotating. This could be a sign of a more serious problem. In this case you should try to replace the battery or recharge it. Oftentimes a weak battery is the culprit. Simply replace it with a fully charged one. If these steps don’t solve the problem you may need to replace the entire power supply. But if you’re in a hurry you can clean the power supply unit with a vacuum cleaner.
Problems with the CPU
If your CPU is acting up there may be several reasons why. If it is not working properly it could be because of the way it has been used. Other reasons for CPU malfunctions could be related to the power flow to the processor. In such a case it may be necessary to replace the CPU. To solve the issue you can try the troubleshooting methods outlined in this guide. In some cases the problem might not be so severe that you can simply replace the CPU.
A common symptom of a failing CPU is random freezing of the computer. This generally happens after you’ve logged into the operating system. The system will not respond to any input from the mouse or keyboard and the screen will remain frozen or display a series of short beeps. You can try restarting the system but that doesn’t always fix the issue. If this happens often it may be a sign of a motherboard problem.
