Plug in a USB drive (note: this will erase the USB drive), select the PC CMOS Cleaner ISO, and write it to the drive. Phase 2: Booting and Using the Cleaner
The PC CMOS cleaner 2.0 USB boot tool can resolve a range of issues related to CMOS settings, including:
The program attempts to decrypt the hash stored on the CMOS chip. If successful, it displays a list of potential matching supervisor or user passwords. Write these down, restart the computer, remove the USB drive, and attempt to log into the BIOS using the discovered keys. Choice B: Wiping the CMOS Registers (Recommended)
Older tools struggle with modern UEFI Secure Boot.

This process is essential when aggressive overclocks, hardware changes, or forgotten passwords prevent your system from booting or completing the Power-On Self-Test (POST) . Methods for Clearing CMOS
While it resets the BIOS to factory defaults, it does not affect the data on your hard drive or the operating system, focusing solely on the motherboard's low-level firmware settings. How to Use for USB Boot
Unlike manual hardware resets that simply wipe all settings, this software-based approach often targets the specific memory addresses where security credentials are stored.
