Intsalling both DDR and SDRAM fried mobo?

I have a Shuttle AK32A mobo. I used years ago, and today pulled it out of it's box to see if it still worked. As I was assembling it, I put a 512mb stick of RAM in 1 of the 2 DDR slots, and a 256mb and 64mb in both the SDRAM slots. When I booted it, I got no beeps, no display, no nothing. Is this because the RAM? Will it ever work again?

Don't laugh at me.

EDIT: I have an Nvidia GeForce 6200 and an AMD Athlon XP 200+. PSU is 500W and working.

from the Shuttle website:

Can I install DDR and SDR SDRAM together on this mainboard?

No. since there is a voltage difference between DDR and SDR SDRAM, using DDR in conjunction with SDR SDRAM may cause permanent damage to both mainboard and memory used.

I will try it. Is there a possibility that it also fried the CPU?
