New build starts but wont post...please look!

[rare]

Hi chaps, just built today the following:

920 i7
P6T Deluxe
6GB Corsair DDR 3 1600
2X SLI GTX 285
Thermaltake 850W

The machine starts, the fans work, the gpu fans come on, the hard drives start to spin, but there is no Lights on the mouse or keyboard and I cant get any further than that....any ideas?

Check all your connections, you remembered to connect 8 pin power cable to mobo too?
are there any lights to indicate HDD being accessed? Could either be just gfx card not seated correct or maybe faulty PSU - it might have enough power for fans/LEDs but not too boot, if all connections are good just try swapping out components for your old ones, you can also test RAM, try one stick at a time see if it posts with any. Good luck, and have patience

Thanks for the input guys. Turns out it didnt like booting with 3 sticks of ram, but its ok now. Got it to post with 1 stick, and now it boots fine with all 3!
