Don't waste your time on it.
Too much damage. Even I would not brother, you need to track out each one of the traces,
and check to see if broken, and then run a new wire from end to end to fix the link.
I done boards with clearly one or two broken traces, but this one has at least five or more.
The problem is I have found even with the traces fixed, the GPU or CPU may be damaged,
as have one of the traces damaged, or sometimes push onto the next trace causing a short,
and then applying power before fixing the damage will cause the GPU/CPU to go crazy and burn out.
Here is the area you need to work on if you willing to waste a week of manpower:
