There are 15 Pins in Monitor cable which is connected to VGA port on the rear side of the Tower. First, we need to reset BIOS settings, and then try again - onboard video card only. for Add-on Video card try reseating video card in diff. slot if possible / reseat video card and try again. if it does not fix it, it could be the problem with Monitor RGB Connection - near the electron gun in the monitor CRT tube. resolder RGB , it will fix it.
