I just got a KT7-Raid mobo, I mounted it to the mounting board in my case (Enlight 7237 w/300 watt ps). I put in the memory, CPU, and video card. I tried powering up, and I get nothing. No post, and my monitor displays, "no signal input". What am I doing wrong? I've already tried reseating the memory, video card, and CPU. Everything seems to be in place. Any suggestions?
