'Puter with an Ouch!

I decided to see if I could get my system goin' today (technically yesterday) and was surprised with nothing!
I turned on the juice, and the CPU and Graphics fan started spinning, and the little blue LED fan was spinning, but nothing on the monitor!
All I've got pieced together is:
I installed the CPU and fan/heatsink, mounted the motherboard on the case and connected the power to the Motherboard.

All I've got pieced together is:
- ATX Case with 300watts
- Asus K8V SE Deluxe
- AMD Athlon 64 +3000
- Nvidia Ti4200 64MB
- Phillips Sound
