- Disable Antivirus Software: Disable any antivirus software running on your system, as it can sometimes interfere with the BIOS update process.
- Ensure Stable Power: Make sure your computer is connected to a stable power source, such as a UPS (Uninterruptible Power Supply), to prevent interruptions during the update.
-
Accessing the BIOS Update Utility:
- Restart Your Computer: Restart your computer and press the designated key to enter the BIOS setup utility. This key is typically displayed during the boot process (e.g., Delete, F2, F12). Consult your motherboard manual if you’re unsure.
- Locate the BIOS Update Utility: Within the BIOS setup utility, look for a BIOS update or flash utility. The name and location of this utility will vary depending on the BIOS version. Common names include "M-Flash," "Q-Flash," or "EZ Flash."
-
Performing the BIOS Update:
- Select the BIOS File: Use the BIOS update utility to select the BIOS file you downloaded to the USB flash drive.
- Confirm the Update: The utility will usually prompt you to confirm the update. Double-check that you have selected the correct BIOS file before proceeding.
- Initiate the Update: Start the BIOS update process. Do not interrupt the process. Do not turn off the computer or remove the USB drive.
- Wait for Completion: The update process can take several minutes. The system will typically reboot automatically once the update is complete.
-
Post-Update Steps:
- Enter BIOS Setup: After the reboot, enter the BIOS setup utility again.
