If you can’t find this key, check your motherboard manual to see which key is used to enter BIOS. Once you enter BIOS, look for Load Setup Defaults option.

This option should be located in the Exit section. Select Load Setup Defaults and save changes. Keep in mind that this process might be different depending on the version of BIOS that you’re using.

Another way to reset your BIOS is to change jumper positions on your motherboard. Most motherboards have a jumper next to the BIOS chip that allows you to reset it. To do that, follow these steps:

  • Turn off your PC and disconnect all cables.
  • Open the PC case.
  • Look for a jumper that has CLEAR CMOS or something similar written next to it.
  • Move the jumper to the clear position.
  • Turn on your PC and turn it off.
  • Now move the jumper back to its original position.

Keep in mind that you need to place the jumper in the appropriate position in order to reset your BIOS.

If you place it incorrectly you can cause permanent damage to your PC, so be extra cautions.

In order to avoid causing damage, we strongly suggest that you check your motherboard manual for detailed instructions on how to change the jumper configuration. Another way to reset your BIOS is to remove your motherboard battery.
