So, have you checked the board with a different known good power supply ?

I have tried with different sources of power and nothing, besides what I need is an electronic response or the steps to follow for this type of problem on the board, so I would like to know if they have the schematic of said motherboard to be able to analyze it

what is your electronics experience ?
the problem is likely to be very difficult if not impossible for the average home constructor to repair

Hi, I'm checking for a smd mosfet from a motherboard and reading on at gate after rising to 1400 ohms down to 700 ohms fast, the other transistors on the same license plate do not do the same thing and I would like to know if this is normal
