My girlfriend and I have the same PC build (only difference is wifi cards). I'm trying to run a ps3 through the pc's mother board (Fatal1ty ASROCK z87killer) which has an hdmi in port. This works on my pc, to my hdmi screen; however on her pc, which uses a vga screen, it wont work. On my pc I just press alt+c and my display switches to the ps3 view, but on her pc the screen goes black and then reappears with the pc screen. Basically, I guess can a ps3 go from HDMI -> motherboard -> VGA screen?
