I can not get anything on the screen when I power on a new machine i am putting together, Abit IS7-E, P4 1.5, 512 Cosair Twinx PC3200, 30gig HDD, Gainward GF4200 Ultra, Antec True Power 480w.

I power up, eveything spins up and I get nothing on my monitor, the amber light on the monitor does not click to green when I power up. Works with other machines. I also tried 2 othe rvideo cards, a agp ATI and a PCI card. I also changed the memory configuration around. and nothing.

Any thoughts, i am drawing a blank right now.
