In that rare case, you need hardware verification: an SPI Flash programmer (like CH341A) and a SOIC clip. That is the "verified" hardware solution for a dead chip. But for 95% of "stuck" PCs? The USB bootable CMOS cleaner is magic.
We have all been there.
You must enter the security settings and disable Secure Boot to allow the USB to boot.
