How to Fix MSI Motherboard Error 99: Troubleshooting Guide for Beginners

MSI motherboard error 99 is a common issue that can leave you frustrated and unable to boot your computer. This error code typically indicates a problem with the motherboard’s BIOS, and it can be caused by various factors.
This comprehensive guide will walk you through the steps to diagnose and fix MSI motherboard error 99, empowering you to get your computer back up and running smoothly.

Understanding the Error

MSI motherboard error 99 signifies a failure during the BIOS initialization process. This can happen due to several reasons, including:

• Corrupted BIOS: The BIOS, or Basic Input/Output System, is a firmware that controls the computer’s hardware during startup. A corrupted BIOS can lead to errors like 99.
• Hardware Issues: Faulty RAM modules, a malfunctioning hard drive, or a loose connection can trigger the error.
• Overclocking: Pushing your system beyond its limits can sometimes cause BIOS instability and result in error 99.
• Outdated BIOS: An outdated BIOS might not be compatible with your current hardware configuration, leading to errors.
• Improper Settings: Incorrect BIOS settings, such as the boot order, can also cause this error.

Troubleshooting Steps: A Systematic Approach

Now that we understand the potential causes, let’s dive into the troubleshooting steps:

1. Power Cycle and Check Connections

Before delving into complex solutions, start with the basics:

• Power Cycle: Turn off your computer completely, unplug it from the power source, and wait for a few minutes before plugging it back in and turning it on. This often resolves temporary glitches.
• Check Connections: Ensure all cables, including power cords, RAM modules, and hard drive connections, are securely plugged in. Reseat the RAM modules by gently removing and re-inserting them.

2. Clear CMOS

Clearing the CMOS (Complementary Metal-Oxide Semiconductor) resets the BIOS to its default settings. This can be helpful if incorrect settings are causing the error:

• Locate the CMOS Jumper: Consult your motherboard’s manual to find the CMOS jumper. It’s usually a small set of pins labeled “CLR CMOS” or similar.
• Short the Jumper: Use a screwdriver or a jumper cap to short the two pins for a few seconds.
• Reset the Jumper: Return the jumper to its original position.
• Power On: Turn on your computer and see if the error is resolved.

3. Update the BIOS

An outdated BIOS can be incompatible with your hardware, causing errors. Updating the BIOS to the latest version can often solve the problem:

• Download the Latest BIOS: Visit the MSI website and search for your motherboard model. Download the latest BIOS version from the support section.
• Flash the BIOS: Follow the instructions provided by MSI to flash the BIOS. This process involves updating the BIOS firmware using a bootable USB drive or a special utility.

Caution: Flashing the BIOS is a critical process. Ensure you have a stable power supply and follow the instructions carefully. Any errors during the process can damage your motherboard.

4. Test Hardware Components

If the error persists, it’s time to test individual hardware components to identify the culprit:

• RAM: Run memory diagnostic tests, such as MemTest86, to check for faulty RAM modules.
• Hard Drive: Use the manufacturer’s diagnostic tools or a third-party utility like CrystalDiskInfo to check for hard drive errors.
• Other Components: If you suspect other components like the CPU or GPU, test them with known-working equipment.

5. Reset the BIOS to Default Settings

If you’ve made any changes to the BIOS settings, resetting them to factory defaults can help:

• Enter the BIOS: During startup, press the designated key (usually Delete or F2) to enter the BIOS setup.
• Locate the Default Settings: Look for an option labeled “Load Optimized Defaults,” “Load Defaults,” or similar.
• Save and Exit: Save the changes and exit the BIOS.

6. Seek Professional Help

If none of the above solutions work, it’s time to seek professional help. A qualified technician can diagnose the issue and perform more advanced troubleshooting steps, such as replacing faulty components.

Beyond the Basics: Advanced Troubleshooting

For experienced users, here are some advanced troubleshooting methods:

• Boot from a Live CD/USB: Create a bootable Linux distribution or a Windows installation disc and try booting from it. If the system boots successfully, it indicates a problem with the operating system or the hard drive.
• Check Event Logs: Examine the Windows event logs for error messages related to the motherboard or BIOS.
• Monitor System Temperatures: Use monitoring tools to check if the system is overheating, which can cause BIOS errors.

A Final Word: Preventing Future Errors

To prevent MSI motherboard error 99 from recurring, consider these preventative measures:

• Regular Maintenance: Keep your computer clean and dust-free.
• Monitor System Temperatures: Ensure your system is running within safe temperature limits.
• Update Drivers: Regularly update your device drivers to ensure compatibility.
• Back Up Your Data: Regularly back up your important data to prevent data loss.
