Computer powers up but nothing on screen and no beep, i change the graphic card and the monitor but still the same i think is Power Supply or Motherboard problem or what else?
ok...remove the front panel connectors as well as the power & reset switch from the mobo header and switch the pc on by short circuiting the power switch header. see if that works or not. consult the user guide if you are not sure which header it is.
