Płyta startuje, pojawiają się wszystkie napięcia poza CPU.
Nie znam historii płyty ale widać, że była wymieniana przetwornica 3/5v PU8701, na rogach PCH nie ma kleju, widać że rezystory R2647 i R2650 były lutowane więc pch też mógł być zmieniany.
Z drugiej strony nagrzewa się do 50*C U4701 n.38,39,40,41,42,44,45,47,48 - 49 Ohm
Próbowałem z innym biosem ale bez zmian.

Remove the chip U4701 from the board and check if anything changes.

Po zdemontowaniu układu płyta pobiera 0,37A
Widzę, że nagrzewają się tylko elementy od GPU więc zakładam, że albo karta jest uszkodzona albo PCH źle wlutowany lub wadliwy.

Try to reflash the BIOS chip. Don't forget to save the old dump.
If it doesn't change anything, replace the PCH chip.
