Ok well i just bought my new case and i moved ll my parts from my old pc to the new case but now it wont show anything on the moniter, the mouse light dosent turn on and my old case didnt have a detachable I/O shield so i just put it in the new case without one would that cause any problems? Also there was a 4pin molex conector (dunno what its called but i think this is it) that went from my psu to my mobo but i didnt put it in because i ran out of plugs (but i can always unhook a fan to hook it up).
