Bios password reset

[ayushmantiku270157e02d8]

Hey guys, im pretty new to this forum so excuse me if i get anything wrong.
about 2 days ago i got home from work and my pc had randomly had a bios password installed i had left my pc on by accident but i dont live with anyone so i dont know how it got there, i checked my cameras and nobody broke in or anything. Ive tried everything, jumping the jbat 1 pins ,taking the battery out for a day and putting it back in, and its still not going away. Are there any other ways i can fix this or am i just gonna have to get a new board?
i have a b550 gaming gen 3 board for context

Try clear CMOS by shorting the JBAT jumper for 5-10 seconds(with PSU powered off and power cord unplugged) to check whether the BIOS password could be removed.

if password can't be erase by clear CMOS then you could only try to contact MSI support for help.
