Computer no post no beeps or anything

Hello,
For my parents computer they purchased the
(intel 925x d925xbclk mobo) https://www.newegg.com/p/N82E16813121229

and

(e3400) https://www.newegg.com/intel-celeron-dual-core-celeron-e3400/p/N82E16819116348

and 2 sticks of PNY memory
https://www.newegg.com/pny-1gb-240-pin-ddr2-sdram/p/N82E16820178094

No onboard video with the board so it is using a nvidia geforce 7600 gs(which was working in the past but has been sitting for a few months)............................


with everything installed i get no post no beeps or anything. Everything spins up and thats it. I have swapped 2 other power supplies, checked every cable, moved both sticks to all four mem slots and same result. No onboard vid scares me as i have no other pcie card to test with. does anyone have any suggestions. This board might be DOA im not sure i would hate waitin for the rma and screwing around with that. Any help is really appreciated.
