    ASUS PRIME B550M-A AC weird behavior

    Hello, I need a little help

    I got an ASUS PRIME B550M-A AC Motherboard, bad BIOS, it wont display or boot, unless I did CMOS Restart first, after that It will boot but if I modified the configuration of the bios and saved it ,again no image

    I got the BIOS .CAP file from ASUS official support, used a tool called ASUS CAP to BIN, and programmed it to the IC, soldered to the board and got it to boot correctly, all the way to Windows, but now the CPU fan stays at full speed all the time and if I try to power it off with power button it will restart instead, and there are probably more issues I have not seen.

    Any help will be appreciated

    Original dump attached

    Thank you in advance, cheers!

    the bios posted is longer...copy and post again...

    The bios chip must be unsoldered from the board before writing or reading..
    do not use the clip, you may have errors..if you do not have anything to unsolder it with,
    solder wires between the programmer and the bios chip..
    Due to a lack of donations, server free space at a critical level, and possible closure of Bios Requests all donations are welcome, click:
