The BIOS actually is a separate system that is independent of a computer's operating systems, such as Microsoft's Windows 7. A computer's BIOS performs a basic check to make sure all of the computer's hardware components are work correctly on initial start up.

Step 1

Turn off your computer. You can only open the BIOS right before you see the Microsoft Windows 7 logo when starting your computer.

Step 2

Turn on your computer.

Press the BIOS key combination to open the BIOS on the computer. Common keys to open the BIOS are F2, F12, Delete, or Esc. Many computers will display the key you need to press to open the BIOS before loading the Windows 7 operating system.
