A COM port is a type of serial port used for communication between a computer and external devices or other computers. COM ports are commonly used in legacy devices, debugging embedded systems, virtualization, and networking in industrial or automation settings. Since modern PCs have physical USB ports, you may be wondering what the purpose of […]

Two beeps indicate a parity circuit failure error on your motherboard. The common cause of this issue includes faults with RAM modules, electrical sources, or the motherboard itself. Reseating the RAM or booting with a RAM stick that you know is good could solve the problem. But in some cases, you’ll need to look beyond

The system timer failure on most motherboards is often triggered by a failing motherboard, overclocking, an outdated BIOS, power supply issues, or malfunctioning hardware. You can detect this issue by 4 beeps during PC boot. Solutions involve resetting components, updating the BIOS, or verifying power supply output. In some cases, further troubleshooting might be required

A memory refresh timer error occurs when the computer fails to refresh DRAM cells within a specified period. It can be caused by issues like corrupted RAM, motherboard or BIOS problems, overheating, or power supply issues. To fix it, run a memory diagnostic tool, update the BIOS, check for overheating, ensure sufficient power supply, and

To enable Precision Boost Overdrive (PBO) on an MSI motherboard, first enter the BIOS, navigate to the “OC” or “Overclocking” menu, and look for the PBO option. Enable it and adjust the settings to your preference. Save your changes and exit the BIOS to activate PBO. Precision Boost Overdrive is AMD’s automatic “overclocking” system that

The COM1 port on a motherboard is a serial communication port used for connecting various peripheral devices to a computer. It is typically labeled as a 9-pin male connector and can be used for communication with devices such as modems, mice, and printers. The port is usually located at the back of the computer and

The boot light on your motherboard means that there’s a problem with your boot drive (HDD or SSD). In other words, your motherboard reached the point where it tried booting into Windows off of your boot drive and failed. Perhaps you were starting your computer, and it then got stuck on the boot light after

The most common cause of DRAM refresh failure is overheating, which can be prevented by ensuring proper cooling. Other causes include outdated BIOS, faulty RAM modules, or power supply issues. Fixing it involves resetting the BIOS, checking for loose connections, replacing faulty RAM modules, or upgrading the power supply if necessary. The DRAM (Dynamic Random

A green light on the motherboard indicates that it is receiving power from the power supply; on most motherboards, this light is usually located near the power connector. However, it does not guarantee that the motherboard is functioning properly, as other components could prevent the system from booting up. If you have just finished your

The SPDIF/OUT header on a motherboard is a connection point for a S/PDIF (Sony/Philips Digital Interface) audio cable. This header lets the motherboard send high-quality digital audio to an external audio device, like a home theater receiver or a digital sound system. In other words, S/PDIF means digital audio. So if you had an audio
