MSI P7N Diamond Nvidia nForce 780i SLI !PROBLEM!

I just recently got my Q9550 processor and MSI P7N Diamond Nvidia nForce 780i SLI motherboard. Everything is connected correctly (including the 4 pin power connector). When i start up the computer it doesn't post. It doesn't give any error code beeps or show anything on the screen. Ive looked threw a ton of threads on multipul forums and no one seems to have this combo out there or theres is working just fine. I was thinking that the cmos battery might be dead in it but not sure how to tell. Anyone have thoughts on what the problem could be?

The ram did the trick for some reason I pulled out one stick and tried to boot the computer up it worked. I shut the computer down put the ram back in the same place and expected it to not boot up... it booted. I checked to see if it was seeing all my ram and it is. I don't know what was goin on with that stick before but its workin now i just hope my box isn't gonna be filled with them wierd gremlins.

Thanks for the reply auscanzukus
