You should also check that the MOSFET is not shorted. Measure resistance across the MOSFET(s), from pin3 to pin2(tab). Also Vcore can be measured without processor installed.
I just managed to destroy two socket 370 celeorons due to shorted transistor before I relized what's happening. It was 5V directly on CPU core. I really hope this is not the case with your MB.
ok so looking at the data sheet
i see on the mofet a drain and source.
I put my multi meter in diode mode
negative on the drain which is the middle pin and then to the right the souce which i put my positive probe
one measured 0.556v almost 0.6v
the other measured 0.192v which is concerning. Both mofets had high resistance nothing opened or shorted
is this the correct way to read it? under 0.3v is a bad mofet.
however i went on this site http://electronicsbeliever.com/how-to-know-if … t-is-defective/ and my mofets passed all the tests.
The only thing i noticed was 0.192v reading on one mofet messured at the drain and source
quite confused here ,seems like there is a crap load of tests for mofets
