All personal computers have a software program called a Basic Input Output System (BIOS) that is saved in a small copper battery on the motherboard. This program tells the motherboard how to operate and allows it to communicate with the different computer components, such as a processor. If you upgrade to a new processor that your motherboard doesn't know how to work with, you will need to update your BIOS driver to get your computer working again.
Things You'll Need
- Floppy disk or jump drive
Open your Web browsing program and navigate to the main website for the manufacturer of your computer's motherboard. Check your computer's user manual or the support Web page of the computer's manufacturer if you aren't sure what company built your motherboard.
Check the "Updates" or "Downloads" section of the website for the motherboard manufacturer and locate the BIOS upgrade file. Click on the link to download the file to your computer's hard drive.
Read the documentation for the update file to find out if it can be run directly from your desktop or if you need to use a "boot disk." Double-click on the file on your desktop if you don't need to make a boot disk and wait for the file to install to complete the installation. Insert a 3.5-inch floppy diskette or a USB jump drive into your computer if the documentation instead prompts you to use a boot disk. Transfer the update file over to the floppy or jump drive and then restart your computer with the disk or drive still inserted.
Press either the "F2" or "Delete" key on your keyboard while it is booting up to access the BIOS settings menu.
Choose the option to boot the computer from the disk or jump drive and then choose the option to run the BIOS upgrade file. Wait for the installation to complete and then turn your computer off and back on one final time to complete the update process.
Tips & Warnings
- Don't turn off the computer while the BIOS is updating, and connect the computer to an secure power supply if possible just in case there is a power surge or outage, which can ruin your motherboard.
