Reinstall Bios

# BIOS, the acronym for the Basic Input/Output System, is a fundamental part of your computer system containing basic control functions. It is a firmware that happens to be the most basic set of instructions your computer needs to operate, regulating how the computer should start up and boot. It is loaded into the memory of the computer when it is turned on. Unfortunately,sometimes the BIOS can get corrupted or deleted due to user error or malicious programs, which leaves your computer crippled and/or unusable. If this were to happen, you'll need to reinstall your BIOS.

    • If yours is an assembled computer, you will need to go to the motherboard manufacturer's website.
  2. Download the bios file appropriate for your motherboard.
  3. Save the file to a temporary directory.
  4. Double-click on the downloaded '.exe' file.
    • This will open a dialog prompting you to extract the required BIOS files. Accept and extract the files into the same directory as the downloaded file.
  5. Write down the exact name of the '.BIO' file that is extracted.
  6. Copy the extracted '.BIO' as well as the IFLASH.exe files onto a properly formatted pen drive. Restart your computer when done.

  • Print out these instructions, as you cannot use your computer while the BIOS is installing.
