This wikiHow teaches you how to access and adjust your Windows computer's BIOS settings. The BIOS is a set of built-in options that allow you to change various aspects of your computer, such as the date and time. Because the BIOS is built into your computer's motherboard, each BIOS looks slightly different depending on the motherboard manufacturer in question.

Steps

Part 1 of 2: Entering the BIOS

Step 2. Wait for your computer's first startup screen to appear

When the startup screen appears, you only have a very short time to press the setup key.

  • It is best to start by pressing the setup key right when the computer restarts.
  • If you see a text like 'Press [key] to enter setup' or something similar appear briefly at the bottom of the screen, then you need to restart your computer and try again.

  • Usually you use one of the function keys (F1-F12) to get into the BIOS. The function keys are located at the top of your keyboard, but you may need to find and hold the Fn key while pressing the appropriate function key.
  • You can check your computer's owner's manual or the computer brand's website to find out which key to press to get into your computer's BIOS.

Step 1. Understand how your BIOS navigation works

BIOS menus cannot be navigated with a mouse, so you must use the arrow keys and other keys to navigate through your BIOS. You can usually find a list of navigation keys in the bottom right corner of the Home screen.

Step 2. Be careful about changing the settings

Make sure you know what the settings stand for. If you adjust the settings incorrectly, your computer or hardware may no longer work properly.

If you want the devices to boot in a different order, open the Boat-menu. In this menu you can indicate which device is started up first by the computer. This is useful if you want to boot from a CD-ROM or USB stick to restore or install an operating system.

  • Usually you use the arrow keys to go to the tab Boat going to change this.

The clock in your BIOS determines what time the clock shows in Windows. Replacing the CMOS battery in your computer will likely reset the clock in your BIOS.

Step 6. Adjust the speed of your fans and the voltage of your computer

These options should only be adjusted by advanced users. In this menu you can overclock your CPU so that your computer performs better. This is best done only if you know everything about your computer's hardware.

Step 7. Save the changes and exit the BIOS

When you are done adjusting the settings you will need to save everything and exit the BIOS by pressing 'Save and Exit' for the changes to take effect. After saving and exiting the BIOS, your computer will reboot with the new settings.

Check the list of navigation keys to see which key you should use to save your adjustments and exit the BIOS

Tips

  • Your computer's BIOS may have significantly fewer settings than another computer's BIOS.
  • Computers with Windows 8 and 10 often have a motherboard that makes it very difficult to get into the BIOS. You will probably have to restart your computer and try several times before you can enter the BIOS.
  • It is a good idea to check the boot order. If your operating system is on your hard drive, make sure the hard drive boots first. This saves a few seconds of startup time.

Warnings

  • Don't change settings that you don't know what they do.
  • If you want to flash the BIOS after adjusting, try the above steps NOT. If you have already adjusted the settings, you will need to reset your BIOS. Instructions for resetting your BIOS can be found here.
