Can not get a POST or BIOS from a Shuttle SN95G5.

Have tried reseting the CMOS with the jumper on the FN95 motherboard as well as the pin switch in the back of the Shuttle case.

SPEC: Athlon 64, ATI 950 video card, Maxtor HD, 2 gig RAM,
Panasonic DVD-RAM drive.

NOTE: System was shipped and upon arrival noted the included video card was not seated properly in APG slot.
Repalce video card with known good card (ATI).

Thank you in advance.
