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...
