Re: Memory woes!
Then either the second set of RAM are bad or your mobo's second set of RAM slots are bad.
Try removing the first set and only use the second set. If it will boot, run Memtest on them. You can also start swapping sticks out to see if it is just a single bad stick by trying to boot with first one stick, and then the other.
Hopefully it is just a faulty stick of RAM.
