You Can use the Forum Bios tool to flash to a previous version of your Motherboard bios.When I bought this motherboard came with a factory BIOS with which it presented these problems that appear on the page you just gave me, sometimes I could enter the bios, or other times the screen was black and did not load anything. All this happens with the NVIDIA GT 730 video card, I have another NVIDIA 210 also happens the same, three beeps.
I tried the solutions provided, but I had no luck, apparently I will have to upgrade the video card.

Starting to sound like you have a Hardware problem.Sorry, I don't seem to have said it. The bios that I have installed is the one that AlanJT just gave me, also I can not enter the boot with f11 because when I turn on the pc the beeps sound and does not show image, sorry if you do not understand, I do not speak English, I use a translator. Anyway I will do what the guide says
