3.7 HOW TO CHANGE COMPUTER BIOS SETTINGS

Knowing how to access and change settings in your BIOS can save you a lot of headaches when troubleshootinga computer. The method varies for every computer, but this guide will show you how to access and change your BIOSsettings.

METHOD 1 OF 3: Enter the BIOS

1. Boot the computer. As themanufacturer’s logo appears, pressthe designated setup button to enterthe BIOS. The key varies bymanufacturer. Typical setups keys areF2, F10, F12, and Del. The key will bedisplayed on the screen with themanufacturer’s logo.

2. Rapidly strike the setup key. Newercomputers can boot very fast. Onceyou figure out your setup key, rapidlypress it when booting the computer.This will give you a greater chance ofentering the BIOS. You may have torepeat the process several times ifyou have difficulty with the timing.

NOTE: If you are running Windows 8and cannot access the BIOS, see theEntering Windows 8 Boot Optionssection.

3. Wait for your BIOS to load. Aftersuccessfully hitting the setup key, theBIOS will load. This should only take afew moments. When the loading iscomplete, you will be taken to theBIOS settings menu.



METHOD 2 OF 3: Adjust Settings

1. Navigate the BIOS. Everymanufacturer has a different layout fortheir BIOS menu, but most sharesome common settings. These includepower settings, date and time settings,

boot order, and more.

NOTE: BIOS menus do not supportmouse input. You will need tonavigate the menus using yourkeyboard. Most BIOS allow you tomove through menus with the arrowkeys, while some use specific keys forspecific menus, or + and – keys fornavigation.

2. Change your settings carefully.When adjusting settings in your BIOS,be sure that you certain what thesettings will affect. Changing settingsincorrectly can lead to system or

hardware failure.

3. Change the boot order. If you wantto change what device to boot from,enter the Boot menu. From here, youcan designate which device thecomputer will attempt to boot fromfirst. This is useful for booting from adisc to install or repair an operatingsystem.



4. Create a BIOS password. You can

create a password that will lock thecomputer from booting unless thecorrect password is entered.

5. Change your date and time. YourBIOS’s clock will dictate yourWindows clock. If the battery hasbeen recently replaced, your clock willmost likely have been reset. You canadjust your clock settings from theBIOS.

6. Change fan speeds and systemvoltages. These options are foradvanced users only. In this menu,you can overclock your CPU,potentially giving more performance.This should be performed only if youare comfortable with your computer’shardware. Check out our [[Overclock aPC | guide on overclocking] for moreinformation.



7. Save and exit. When you are finishedadjusting your settings, you will need

to save and exit in order for yourchanges to take effect. When yousave and restart, your computer willreboot with the new settings.

METHOD 3 OF 3: Enter Windows 8 Boot Options

1. Understand what is new withWindows 8 booting. Windows 8often boots too quickly to manuallyenter the BIOS menu via the setupkey. If you are running a solid statedrive, you may have as little as .2seconds to successfully press thesetup key. Windows 8 allow you toenter a new Advanced Startup menuthat replaces the functions of theBIOS.

NOTE: This method only works if youhave a UEFI-enabled motherboard. Theseare relatively recent releases, so oldersystems running Windows 8 will have toenter BIOS the old manual way.

2. Open Windows Settings. You can dothis by pressing the Windows key + Cto open the sidebar. Click the Settingsbutton in the sidebar. Once theSettings menu is open, select theGeneral tab.



3. Restart with Advanced startup.Under the Advanced startup section inthe General settings, click Restart

Now. This will reboot the computerinto the Advanced Startup menu.

NOTE: Alternatively, you can hold downthe Shift key while clicking the Restartbutton in the Shut Down menu.

4. Adjust your settings. To access theBIOS settings, click the Troubleshootbutton. This will open the “Advancedoptions” menu. From this menu, youcan adjust your BIOS settings byclicking UEFI Firmware Settings. Ifyou don’t see this option, you do nothave a UEFI-enabled motherboard.

5. Change the boot device. If youwould like to boot from a disc oranother drive, return to the main Advanced Startup menu. Click the“Use a device” button. This will allowyou to select which device you wouldlike to boot from, such as your DVDdrive or a flash drive.



3.7.1 Tips

A useful task is to check the boot order. If you have the OS on the hard drive, make sure that the hard drive is thefirst in the boot order. This can save a few seconds off boot time.

Keep a copy of your motherboard's documentation (a.k.a. User Manual) with you in case you can't get in or out ofthe BIOS, or you need help changing something.

Backup your BIOS settings by recording them on paper once your PC is running and before you make anychanges to them.

3.7.2 Warnings

Don't change anything if you don't know what you're doing.

If you are going to flash the BIOS after, do NOT attempt this. If you have already changed settings, you mustreset your BIOS. Instructions on how to reset your BIOS can be found here: Reset Your BIOS
