My DVI doesn't work - no display on the monitor

Hey, guys... I'm just wondering if someone can help me here about my DVI.. Because earlier my DVI cord still works on my Acer X193HQ 18"5 and I tried to dual display my MSI N430GT in a VGA.. I connect the two monitor on my one video card, the Acer X193HQ in DVI then I have another monitor Acer H193HQV in VGA... After I turned it on my pc.. Theres no display.. I turned off my computer then back on a single monitor the DVI-I on my X193HQ = no display (no signal) But when I plug my VGA to the monitor is has a dispay but when DVI it has no signal... Please help me.. I need a DVI so that I can NVIDIA scale it cause VGA doesn't have NVidia Scaling.. Thanks
 
Check your DVI cable for bent pins at each end. For test purposes try to get another DVI cable and see if it will work.
