Its still not clear to me. This is what you posted at#24

pq201 first mosfet
Source & drain 3.7mohm
Source & gate 3.69mohm
Gate & drain 0 mohm

pq202 second mosfet
Source & drain 4.1mohm
Source & gate 3.75mohm
Gate & drain 0mohm

The multimeter have auto scale - and when I measure, I put the resistance mode and here was 0 mega ohm.
Open circuit.

Yes. You asumption was write.
Value was rising, then value was show like nothing connected.
For moment I have to find some n-chanel MOSFET on some donor defective motherboard.
