Question

I have the Asus M3a32-MVP WiFi deluxe mother board with the AM2 CPU chip. i have 2 Xfx 9800 GTX Sli ready cards for graphics and a Fatality sound card made by creative. I'm running the suggested corsair memory which is 4G 2+2. Every time I try to start the system up I get the warning beeps and in 15 sec it turns off. I tried another memory type and it stayed on but no picture. the memory I tried to run first is from the Dominator series. How can i get my dream machine running. Help please :.(
