Reset Your CMOS

Do you want to reset your CMOS? If yes, then you are in the right place. The CMOS also called the Complementary Metal-Oxide-Semiconductor. However, it is a small piece of memory used to save your PC BIOS or UEFI configuration. The configuration controls what your PC does on boot. If you’ve crushed your BIOS with a failed overclocking setup or your machine can’t boot properly, moving back the BIOS or UEFI to the factory defaults can certainly set things right. You will also lose any custom BIOS configurations. But those can easily reset. If you have an especially complex setup, you can also recover your working UEFI settings and recover later. You probably don’t have one now, but it’s a good technique for the future.

After you built your own PC, it must be quite easy to reset your CMOS. Pre-built systems probably be a little tough, but you can make one of the techniques below that works for you.
