Fans stop spin and i flash bios ,but after no picture any more all power voltage are present..Please help

How can I help you ?

After flash bios from this site ,doesn't turn picture on screen I save old one, again I flash bios but same result ,I don't understand why this happen ..I measure by oscilloscope on 2 leg of bios no signal :(

and before that it was ?

Before was ok,only fan didn't spin ,I decide flash bios after black screen ..On fan red voltage only 0.200 v..

why flash it then?

put another fan in first to check
p.s. fan controlled by multicontroller

perhaps something has been taken down. maybe you need to flash the multicontroller
and what to say without measurements. there processor ryzen ?

It Ryzen CPU..I did by vertyanov flash EC .. Before I change fans ,I test fans by power supply spin norma(fans are ok)..Before flash bios laptop was working ,only fans did not spin ,that is reason why idecide flash bios..Better If I was not flash,but now is late:(

this is my old bios and EC..Wow i flash bios with programmer 1.8v and laptop turn on..But fans not spin:(this bios are working )
