PC doesn't boot.

I've just got Q6600 G0. After installing it on the motherboard I tried to turn on the computer, but there was black screen. All the fans are working, DVD-burner too. There were no speaker sounds. What is the problem?
My hardware is:
Gigabyte P35-S3 rev. 1.0;
Intel Q6600;
Sapphire Radeon X1950GT;
2 Gbytes Patriot RAM;
Samsung HD501LJ.

It's alright now. I forgot to connect power cable to the motherboard :).

Glad to hear it was a simple mistake and not something serious.
