tengo una motherboard biostar a780l3b con un procesador athlon II x2 245 le puse una rx550 y me salta esto, se queda colgado ahi tengo que tocar DEL antes que aparezca para entrar a la bios, la fuente esta ok, la bios la actualize, la placa la probe en otra pc y funciono tambien, hasta la probe en una pc muy vieja con pentium4 y funciono, asi que es la mother pero no se que es lo que tiene, si la pruebo sin la placa de video funciona sin problema, el puerto pciex16 funciona porque probe otra placa de video y tamb funciona, tambien intente usarla con la placa de video pero iniciando desde el integrado y se queda en negro

Translation from moderator:

I have a biostar a780l3b motherboard with an athlon II x2 245 processor I put an rx550 on it and this skips me, it hangs there I have to touch DEL before it appears to enter the bios, the source is ok, the bios updated it, the board I tested it on another pc and it worked too, even I tested it on a very old pc with pentium4 and it worked, so it is the mother but I don't know what it has.

if I test it without the video card it works without problem, the port pciex16 works because I tried another video card and it also works, I also tried to use it with the video card but starting from the integrated one and it stays black.
