HEEEELLLP: P4C800 Deluxe Problem! It doesnt boot up now!

And now when I boot up it just beeps 3 times repetitively. Long shot shot...Long short short...etc.

What do I do?

I think that all along this mobo has disagreed with my Corsiar XMS ram. For some reason now when I turn it on I dont get any beeps! AGH! Maybe this old powersupply I put in shorted from something? Any ideas MOBO gods and goddesses?
