Default Missing 12v in asrock z77 extreme 4

Hi Folks:

I have this board and attached a GPU that created a short in 12v pciex port lines (the slot). Something smoked with white smoke but nothing looks burned. Around the VRM was some smell. No idea if from GPU or motherboard. Nothing looks burned from GPU or motherboard. I do however have many points where there should be 12v and there is 374 ohm to 12v atx line. I post image with blue circles where there are 0 ohms. I was thinking to bridge with wire as pictured by green line since I find no other component that could be damaged and assume maybe a cooper line got damaged. Any ideas??

This is the link for board view file

Everything disconnected from +12v is connected between them. I tested with continuity. But reads 374 ohm to +12v atx input port.
