PC motherboard help
« on: October 03, 2021, 03:16:20 am »
Hello
i am trying to fix an old motherboard that does not boot due to bulged capacitors, those capacitors are on top of the cpu socket, so i decided to remove those capacitors and then buy new ones, before removing the capacitors, i tested them using the continuity mode on the multi-meter and there was no short, after i removed those 5 capacitors the board is shorted to ground not only on the spots where the capacitors were, but also on other spots, is this normal or did i destroy the motherboard?

Are you sure you put the multimeter probes the same way around both times?
There are plenty of (normally reverse-biased) diode junctions across the power rails and if your multimeter's test voltage is higher than their Vf, they can conduct.
