I havent posted back not because i dont find the information helpful, but because its kinda hard to access the internet with a broken BIOS. I know that replacing the BIOS is an option, but i really dont want to do that. I dont know whats a bootblock, so could someone please explain? My mobo is a MS-6390(Microstar). I was hoping that theres a tool to reflash the bios externally. thanks for all the help thus far.
