so basically my I bought a computer long ago and I never got to using it and now when I try to use it apparently the guy who sold me this computer took out the gpu which I just bought a new one but when I plug it in there is an error code that said 97 which I did some research and apparently my motherboard needs a bios update, but for this motherboard there is no bios flashback button for me to update it and when i tried to look up the manual i can't find it anywhere, so does anyone know is there any other way for me to get this motherboard to work
