The most universal method for desktop PCs is a physical CMOS reset:
You fire up that old Pentium III from the garage, or you are trying to resurrect a high-end gaming rig from 2012. You press the power button. The fans spin. The hard drive clicks ominously. But the screen stays black. You hear the dreaded beep code: Beep-beep-beep-beep .
The plastic casing was cracked near the connector. The LED indicator was dead. But the drive still had weight.

Whenever possible, use your utility's "dump" or "save" feature to log the existing CMOS configuration to your USB drive before initiating a total wipe.
If you have ever been locked out of your computer’s BIOS, you already know how frustrating it can be. Whether you bought a used laptop from an online marketplace, forgot a password you set years ago, or simply inherited an old office machine with a stubborn security lock, gaining access to the BIOS setup is not always straightforward. Fortunately, a niche but remarkably effective solution exists: , a free, bootable utility designed specifically to recover, erase, decrypt, or display BIOS passwords stored in the CMOS memory.
• Easy USB boot — ISO verified for reliable startup • Supports wide range of chipsets and legacy BIOS/UEFI modes • Safe: read-only diagnostic tools with optional CMOS reset • Lightweight and fast — boots in seconds
After Rufus creates the bootable drive, download the utility from a verified source (e.g., the official Ultimate Boot CD repository or an overclocking database like Overclock.net). Look for the SHA-256 checksum to verify integrity.
He plugged it into her laptop’s USB 2.0 port—the only one still active after she’d disabled the 3.0 controller as a precaution.
💡 On most modern computers , the BIOS password is no longer stored in the traditional battery‑backed CMOS (the real‑time clock chip). Instead, it is saved in an EEPROM (Electrically Erasable Programmable Read‑Only Memory) , a more secure storage method that this tool cannot directly access. Users with very new motherboards (post‑2018–2020, depending on the manufacturer) should be aware that PC CMOS Cleaner may only reset non‑password CMOS settings , not the actual BIOS password itself.

: Plug the drive into a USB 2.0 port if possible, as some boot tools have better compatibility with older ports .
Here is where the internet gets dangerous. You can Google "CMOS reset USB" and find a million sketchy forum posts with broken links to cmospwd.exe or random .iso files. Downloading random boot images is a great way to inject a rootkit into your BIOS before you even get to the login screen.
