How To Clear Cmos Msi?

CMOS (Complementary Metal-Oxide-Semiconductor) is a chip on your motherboard that stores important information related to your computer’s BIOS (Basic Input/Output System) settings. Clearing the CMOS may be necessary when troubleshooting issues related to BIOS settings. While clearing CMOS on MSI (Micro-Star International) motherboards is a straightforward process, it is essential to follow the correct steps and precautions to ensure that you do not damage your computer components.

In this article, we will guide you through the process of how to clear the CMOS on MSI motherboards. Whether you’re experiencing boot problems, hardware malfunction, or other system issues, knowing how to clear CMOS can be a helpful tool to get your computer back up and running smoothly. Follow these easy steps to clear the CMOS on your MSI motherboard safely and effectively.

How to Clear CMOS MSI?

Clearing the CMOS (Complementary Metal-Oxide-Semiconductor) on an MSI (Micro-Star International) computer is a useful troubleshooting step that resets the BIOS (Basic Input/Output System) settings to their default state. This may be necessary if the computer is not booting properly or if there is an issue with the BIOS settings. Here are the steps to clear the CMOS on an MSI computer:

– Turn off the computer and unplug all cables.
– Open the computer case and locate the CMOS jumper. This is usually near the edge of the motherboard and labeled as “JBAT1” or “CMOS Jumper.”
– Move the CMOS jumper from the two pins it is currently on to the two adjacent pins. This will close the circuit and clear the CMOS. Be sure to note the original position of the jumper so you can return it to its original position later.
– Wait a few seconds and then move the CMOS jumper back to its original position.
– Close the computer case and reconnect all cables.
– Turn on the computer and enter the BIOS setup by pressing the appropriate key (usually Del or F2) during the boot process.
– Reset any BIOS settings that were changed or customized since the last CMOS clearing.

Note: Some MSI motherboards may have slightly different steps or jumper locations, so refer to the motherboard manual or MSI website for specific instructions. Also, be sure to handle all computer components with care and caution to avoid damage.
