Hello smart people :) i need your help

So i have replaced the 6.3v cap with my pro skills (aka janky af look at the pic) but it still wont post, i have a multi meter but no knowledge of where to poke the little bastard? or what to look for :(

Figured i could post a picture here and see what you pros think?

(Things i tried) replacing the cap, shocking the core, using another gpu to see if Nvflash might see it, randomly probing things to see if they dont beep :) i just feel the core is not getting power, not warm to the touch when in the machine

Can anyone give me a ruff idea of where i should be looking for?

(bottom right there are 4 caps that look like the one i replaced, none of them give any reading) Does anyone know there value?? or what this part of the board does?

Could someone brake down the different area's of the board for me?

Some of the tiny caps on the back will beep only at one end, are these the dead ones? one does not beep atall

Plus am i right about the row of 4 caps? they dont show any value when tested, the creamy yellow ones. What value would they be?
