#1 MSI MGP B550 Gaming Plus - płyta nie odpala, dioda CPU Debug ciągle świeci

Cześć. Dioda CPU świeci cały czas, procesor dostaje napięcie z wszystkich faz, płyta (a właściwie procesor) nie wystawia sygnału SPI_CLK na kość biosu. Nóżka AW14 procesora jest PullUp do 1.8V (PWR_1P8_SW), więc zgodnie z dokumentacją, procesor powinien przesłać zegar zewnętrzny z nóżek AJ1 (APU_48M_X1) oraz AH1 (APU_48M_X2) na nóżkę AW14 i finalnie do Bios flash, ale tego nie robi... Czy ktoś ma pomysł co jeszcze, prócz napięć (które wydają sie być ok) sprawdzić? Może procesor musi przejść w stan P0 a czegoś mu brakuje?
