Motherboard Green/Black short circuit?


Beta member
Hello everybody,

i have a d33007 motherboard, and for some strange reason green and black contracts on the motherboard have a closed circuit when i test them, thus the power supply turns on as soon as it is plugged in, and nothing else happens, no beeping without ram, no anything. i took all the pci and video card out, no help. i even took the motherboard out to see if there is anything contacting it on the back.
also note that the previous power supply that was in there when the problem started does not work anymore.

thank you
