Are you getting DC-In on the motherboard side pins of the [https://electronics.stackexchange.com/questions/291413/usb-c-to-usb-a-pinout|USB-C connector], you didn't say?
It may be easier to try and find the schematic diagram for the motherboard and then try and work out where the problem is.
Search online for ''(insert motherboard's board number, including Rev. number if any) schematic'' to hopefully find it''.''
There are power regulators on the motherboard which may have been damaged so knowing which ones are being used where, would be an asset, otherwise you're just randomly testing components looking for a problem that may not even be at the point on the motherboard that you’re testing.

What does a "normal" resistor mean? Resistors can vary from 0 Ohms to 100s of MOhms. You would need to look at the resistor’s case marking to determine its' value and then test if it is correct. If there are no markings then you will need the schematic to know what to replace it with if it is determined that it is faulty as all you would have would be its’ board designation.

[https://www.fluke.com/en-au/learn/best-practices/test-tools-basics/digital-multimeters/how-to-test-diodes-using-a-digital-multimeter|diode test mode] is just that, a function of the DMM to test diodes, not resistors. The DMM applies a fixed amount of current to the diode under test and then gives a readout as to the voltage drop across the diode indicating whether it is conducting OK in one direction and not the other (as a diode should) or whether there are problems with it.
Not trying to dissuade you but fault finding in electrical/electronic circuits without the schematic diagram, unless you are familiar with the circuit or the fault is obvious is very difficult and time consuming.
