To update the BIOS, download the latest BIOS version from the ASUS support website, extract the file, and copy it onto a USB drive. Restart your computer and enter the BIOS setup by pressing the DEL key during boot. Navigate to the 'Tool' menu and select 'ASUS EZ Flash 3 Utility'. Follow the on-screen instructions to update the BIOS from your USB drive.
First, ensure all power connections are secure. Check CPU and RAM seating, and ensure no components are shorted. Try using the 'Clear CMOS' button to reset BIOS settings. If the problem persists, attempt booting with minimal hardware to isolate the issue.
