    Msi ms-7613

    Hi,
    I have a MSI-MS7613 that isn't starting. The PSU is OK, and when I try to start the fan spins once and stops. It starts to do this cycle until i switch it off. I found that a USB port had been shorted, and the respective fuse has blown. Today, it tried to turn on the motherboard without the additional power cord (4 pins) and it's apparently working, which tells me after reading some other posts from this forum that I have a MOSFET from the CPU VRM fried. The problem is to find it. Does anyone have a schematic for this board or any clue how I can solve this problem.

    Thanks.

    Ok,
    Just figured out that the mobo does not start without the fan connected and the CPU in place.
    Now it starts but nothing happens, no sound, nothing, just the fans running...

      After some digging, just found that i had some MOSFET shorted. The Major problem now is to find some replacements. Could someone tell me what mosfet can i use. The ones that were in place and are burned are Nikos PO903BD and Nikos PO603BD.

      Thanks in advance.
