(My Monitor works with other rigs)
use the jumper in your motherboard.
How did you reinstalled the OS when you can't even see the display ??? Tell us your config.
Do the fans run continuously? Or do they sop and run then again? If this is the case then your motherboard is the fault, you can also check the same by removing the ram sticks and if you hear beep codes then your motherboards all right and if not probably you have to change it.
just try this
press caps lock, if the light does not come and go at each keypress, then your motherboard is gone.
