Currently i'm working on a board for repair and i noticed that one capacitor in special is showing 77 ohms when i measure continuity between both sides, would that be a bad cap or maybe i'm measuring some alternative current path since the capacitor would be O.L ?
Currently this board is filled with bulged electrolytic caps and it doesn't post, but the cpu get warm(my guess is that the voltage is being delivered to the cpu, but it is unstable enough to prevent the proper cpu functioning.

Resistance while the part is in-circuit is normal to have. The greater the power use in that particular area the lower the measured resistance is.

Thank you for answering, well i suspected that, but i wasn't sure, so i thought that asking here someone with more experience would confirm that.
Well hopefully recapping this board will bring it back to life,it has nothing special but for idk, i feel bad throwing out hardware.
