I have just built a new PC from scratch as follows...
400w ATX Power supply
P4 3.0G Prescott CPU
Asus P4P800S-X Motherboard
2 x 512mb PC3200 DDR400 RAM
160 GB Sata Hard Drive
Leadtek AGP8X 128mb 9500XT graphics
Sony CDRW / DVD
I have attached all components as per usual. And Jumpers, power cables etc etc. However when I power up, I get no output to the monitor. The mother board powers up ie the led is on. The Graphics card fan powers up. The CPU Fan powers up. The Internal Fan powers Up. But no output. I have tried swapping monitors and graphics cards but neither has worked. Perhaps I am doing something stupid. Can any one help???
