Unable to enter installation

[pokeycam]

Hello,

 

I have a new PC and I'm trying to install Snow Leopard (10.6.0). I have followed the steps on Lifehacker but when I try and boot from the USB it loads up saying that I need to restart my computer (different languages), I do this and the same thing happens again and again. Can someone help?

 

My computer specs are

Motherboard: Gigabyte N650SLI-DS4L

CPU: Intel Quad Core (64-bit)

Graphics: NVidia GeForce8800 GTX

 

Please can someone help?
