I noticed a strange thing now in the contents recorded on one of the bios of the motherboard.
I downloaded the contents of memory M_bios from the gibabyte website.
1 ° I recorded the last version of the bios in memory M_bios
2º When I went to read the contents of the memory B_bios I noticed that it was blank, there was nothing recorded there.
3rd anyway I recorded the last version of bios in this memory B_bios.
4º After recording the two memories, both being equal, there is no video on the monitor besides looping on the diagnostic card.
I'm going to carry out a voltage measurement on all the pins of the two memories, then I put the result, okay.
