Good advice from stormy.

Also try re-seating the RAM cards.
If that doesn't help, check your manual for the recommended slots to use.
If that doesn't help, move all cards to the alternate slots.

Still not seeing the RAM, run memtest86+ with one card in one slot, then move to next slot with the next card, you are looking for bad RAM cards and bad motherboard slots.
