Things to try:

- Try using the 'old' PSU instead
- Re-seat the CPU/heatsink (make sure it is on the right direction)
- Try running the computer OUT of the case (place motherboard on wood/phone book, and try powering it up with the bare minimum: CPU/Heatsink, PSU, Motherboard, Memory, Video Card)

Stupid question
Is the cable connected?
And, some monitors have multiple inputs, is the correct input selected?

(eg. better nokia monitors have bnc/vga input select. some sony models have 2 vga inputs)

Also make sure any other power cables going to the motherboard are plugged in. I had to do some "tech" support over instant messages, and when I told my friend to plug in the extra 4 pin 12v power, it turned on.
