How to Reset Your BIOS

Did you recently upgrade your PC, change its components, or test a setting in the BIOS that now stops it from powering up all the way? Here's how to reset your BIOS. First of all, if you have, read the manual to the motherboard and look for BIOS or CMOS Reset. Generally, the easiest and least fiddly method is to remove the power cord from the computer, open it and look for a button battery (usually bigger than the ones in a watch) remove it for for five or ten minutes. Theoretically this should work.

If no manual is handy and removing the battery did not work try the following:

Steps

1
Power down your PC.
2
Locate a rocker-style switch at the back of your PC (if applicable), and switch it from the on position (I) to the off position (O). If there is no switch disconnect the power cord from power supply.
3
Find the 3-pin jumper near the power supply on the motherboard, typically labeled "Clear CMOS" or "Reset BIOS".
4
Remove the jumper from the default position (typically connecting the 1st and 2nd pins).
5
Replace the jumper to connect the 2nd and 3rd pins.
6
Push the power button on the front of your PC once.
7
Wait a minute.
8
Return the jumper to its default position, connecting the 1st and 2nd pins.
9
Move the rocker-style switch at the back of your PC (if applicable), to the on (I) position.
10
Power on your PC with its front power button. If it doesn't work go to alternate options.
11
Open Command Prompt , click Start Menu > Run > type CMD (enter).
12
Type debug.
13
Type this code:

71 20
14
Type quit.

Alternate Method 1

1
Locate a rocker-style switch at the back of your PC (if applicable), and switch it from the on position (I) to the off position (O).
2
Remove the CMOS battery. This should be a regular 3V, round, flat watch battery.
3
Wait at least 5 minutes.
4
Reinsert the CMOS battery.
5
Move the rocker-style switch at the back of your PC (if applicable), to the on (I) position.
6
Power on your PC with its front power button.

Alternate Method 2

1
Turn on your computer and press the key on your keyboard to enter the BIOS. This is typically the Del (delete) key. Pre-built systems from major manufacturers may use a function key such as F1, F2, or F10.
2
Go to the last tab or page of your BIOS.
3
Select an option similar to "restore factory settings".
4
Save your changes and confirm your selection if necessary. This will often be combined with the process of exiting a BIOS. Some BIOS types may have this as a separate option such as "F10: Save Changes".

Tips

Don't forget to configure your BIOS after this process. Without any custom configuration, most systems should still function adequately with their default settings.

Warnings

Make sure your computer is unplugged before removing the case. Ground yourself before handling any components inside a PC to reduce the risk of electrostatic discharge from damaging your PC.
If you don't know how to configure your BIOS, don't mess with it. You can damage your PC.
