    USB not power up on DELL XPS 400

    Computer Dell XPS 400 motherboard part no. FJ030

    Hi, this is my first post here and hope to get some light. I'm trying to see if my motherboard has a bad cap problem.


    Problem: Computer wont boot. I see the bios info but mark a keyboard error the mother board only have usb ports no mini dim and none oy my motherboard ports works.

    Test: I already test the power supply and it's delivering the right amount of voltage, I buy a pci usb port cards and those usb ports wont work either.

    Mi hypothesis is that some bad caps on the board i inspect most of them and I dont see any visual problems.

    I will like to know opinions.

    Thanks

      Watch out for United Chemicon KZG on that board..... check them for shorts.

      KZG can fail with no signs, Id change them all if you have them.
