Good for clearing boot problems or overclocking jams
If your already here I don’t need to explain what the Basic input output system (BIOS) is do I?

To reset your computer BIOS:
1.turn off your computer and turn off at wall socket but do not remove plug as this will keep you and your system earthed and prevent static damage to your mother board.

2.remove side of case

3.you will see a small silver watch battery attached to the M/B

remove-battery
4.remove the battery by pushing the silver spring to the side, the battery should just drop out

5.wait 10-15min and push the battery back into the holder on the mother board. ( Replace with new one if required)

6.reboot the system and set the bios up if needed.
