New Machine Won't Boot

Ask the Doctor LogoDoc, I just built a new system with a 2.66GHz Core i7-920, Asus P6X58D Premium, 3GB of Corsair DDR3/1600, two GeForce 8800 GTs in SLI, two 250GB Barracudas, and an 850W Corsair PSU in an Antec 1200 case. It’s all stock-clocked and the GPUs, HDDs, and PSU were from an older machine and functioned fine.

My problem is that my new rig doesn’t work. I power on, but no boot. No POST, nothing on the screen, no beeps. The MEM_OK LED is on and it is red. The manual says that means the RAM is not properly installed.

So, I check to see if they are all in the correct slots, and they are. I pull them all out and put them in, one at a time, and none of them work. I took a stick from a working computer and it doesn’t work. I try it on every slot, same. I take my Corsair RAM and try it in the working computer, and it all works. I power on the system with no RAM installed, and same thing; no boot, no POST, nothing on screen.

After all that, I put the Corsair RAM in and took out the videocards. I then put a 9800 GT from a working computer in and the problem is the same.

So, any thoughts? Aside from assuming that the board is defective, I don’t know what else to try troubleshooting. I have heard that Asus has had some problems recently with RAM slots not working. I may have fallen victim to that. Maybe a jumper I don’t know about? As far as I can see, the only jumpers on the board are related to OC’ing, and I didn’t change any of them. Let me know what you think.
