board came in very clean. no water, or physical damage
ppbus is short to ground. i removed f7140 and found ppbus_g3h side is shorted and the filter was blown. I checked the cpu caps are all fine, cpu vcore is reading 22.7ohms so that checks out that cpu is good. I ran a freeze test and nothing is showing up so now i'm stuck. most of the videos on youtube with ppbus short to ground are all cpu caps so i don't know where to go from here.
