• Unplug AC and remove the battery (if removable).
• Locate the CMOS battery on the MS-14B31 board (a small coin cell). Disconnect it for 5 minutes.
• Reassemble and try booting. This restores default BIOS settings.

1. Identify your motherboard model: Verify that your motherboard is an MSI product and note down the model number. You can find this information in the motherboard manual, on the manufacturer's website, or using a system information tool like CPU-Z.
2. Check the current BIOS version: Use a tool like CPU-Z or the motherboard manual to determine the current BIOS version. Compare it with the latest version available on the MSI website.

4. Use a reliable power source: Ensure your system is connected to a reliable power source, such as a UPS (uninterruptible power supply), to prevent power outages during the update process.
