I recently built a computer, and had the unfortunate luck of having a dead mobo. I got a new mobo(ASUS P4S800D-X) today, which required me to also get a new video card(Nvdia GeForce FX 5200 AGP 8X). Everything(HD,CD,DVD-ROMs, Fans, lights) powers up, but my monitor recieves no signal. I've tried switching the RAM to different slots, I've disconnected everything but one stick of PC3200 DDR 512MB RAM, the video card(as the board has no onboard video), the CPU/HSF. I've tried 2 different monitors that I know work. Everything is plugged in and seated properly, and compatible to the best of my knowledge. Still no signal to the monitor.
