Bump
I'm having exactly the same problem
Once turned on, it doesnt send any video signa(so it doesnt post), so the monitor just sits there looking silly

I've tested different video cards(GF4 Ti4200, MX440), CPU's( both athlon XP 2000+), RAM(kingmax, corsair), and PSU's(Aopen 300, and ernemax 350)
By the way, my friends and I have tried it on _2_ of the exact same boards. I think it might be dodgy AGP or something, but I doubt it would happen on 2 Mobo's (Make that 3 including yours)
