Now, on to a more productive thought... Have you made sure the motherboard is dead? I am almost entirely sure that your CPU will probably be okay, so try a new motherboard from a local retailler. If it does not work, your CPU is bad, or you are doing something wrong. Return the new motherboard and buy a new CPU. Test the new CPU in the "broken" motherboard, and if it doesnt work, try a different motherboard. It is unlikely that you fried BOTH the motherboard and CPU. I would guess the motherboard is the only dead thing, CPUs are durable as hell.
I agree, I bet anything that its the motherboard that shot. I would test out the motherboard and then the processor. Worst case scenario if both are fried, just spend your $200 on a $100 motherboard and a pentiumD processor and upgrade to a coreduo once you earn the money.
I don't like the whole RMA thing when its clearly your own fault. I've done similar shit before, and it sucks but the best thing to do is just suck it up and take responsibility. Just learn from the experience so you won't make the same mistake twice.
