Method 1 – Remove Battery
For desktop user, open up your computer casing and look for the battery. Remove the battery for approximately 5 minutes (maybe longer, depending on the motherboard) and slot it back. By removing the battery and deprive the motherboard’s flash memory of power supply, you are essentially resetting the settings back to default when the existing data in BIOS are cleared.
This method works well for desktop, however this is not practical for laptop user unless the warranty expired long time ago. This method might or not not work, it depends on the type of motherboard.
