Hi all, I am trying to repair a motherboard from asus that suddenly stopped working. There was a shorted mosfet in the vrm. I connected the cpu power pins to a lab power supply and a Nikos P0903BDL mosfet (second row in the picture) got very hot. After replacing it with a P0903BDG (already replaced in the pic) the motherboard starts but does not post.
I noticed that the cpu doesn't get hot without a cooler when the motherboard is turned on. I suspect that there are other defective components in the VRM.
I have a tester that can test mosfets. Should I just remove all the mosfets from the VRM one by one to test them? Or is there something else I should check first?
