Idk whats wrong computer wont turn on

Last night i had an update, since then my computer would turn on, everything running all fans spinning, everything, my computer would sit there on a no signal for my monitor and keyboard + mouse would not work. After unpluging everything 1 by 1 my computer finally showed the startup screen (after removing graphics card + second monitor) and my mouse would start glowing up again. It would uninstall the update and let me go all the way to the desktop but the moment i turn my computer off and plug my graphics card back in it refuses to work, just does the same thing it did befor, graphics card is working fine, i had this problem last month but it randomly fixed itself and i had to remove the graphics card last time to, What do i do im clueless
