I'd bet you've done the motherboard in. And, sadly, you've likely blown the warranty in the bargain.
What you need to do now is get some other memory and test it in your machine. If that works, it's the memory, if not, it's the motherboard.
(Don't put your memory in another machine, you might end up replacing 2 motherboards.)
