Dealing with the same thing, still kinda new to pcs but is it possible for a mobo to be damaged and keep it from post or booting even tho its still supplying power to gpu and harddrive? ( both are lighting up and spinning, same with all my fans and cd-rom ) no beeps or signals to monitors at all tho .
