Firmware or BIOS corruption causing boot failures on Windows 10

My Windows 10 PC won't boot, and I've traced the issue to what I believe is firmware or BIOS corruption rather than a typical Windows or hard drive failure. The system powers on, but I get a black screen or an endless boot loop with no POST beeps, and I've tried clearing the CMOS, updating the BIOS via USB, and swapping hardware components, but nothing resolves the boot failure, and I'm now looking for any advanced recovery methods or tools that can reflash the firmware or repair the corrupt UEFI partition to get my system running again without replacing the motherboard.
