First Build SOS

[Maniacfest]

Hi People.
I have just built my first PC and have need a bit of help.

Here's the problem: Upon start up, nothing displays on the screen, the screen is not detecting any input. I have made sure everything is plugged in correctly and all the fans are spinning, including the one of the GFX card. There are no beeps on startup and I know the speaker is working as I took out the GFX card just to test, and it beeped.

So far I have tried:
-Changing the GFX card
-Using the second PCI slot
-Changing the keyboard
-Changing the monitor
-changing the hdd to another sata connection.

Other Info:
Don't think the keyboard is getting any power as when I press caps no light come on on the keyboard.
Half of the 8 pin connector is covered by a piece of plastic that I don't think is meant to be removed.

Spec:
- Asus P6T
- Intel Core i7 920 Retail
- Nvidia 8800GTX
- 6gb Corsair XMS3 1600mhz
- Corsair HX 750w
- Samsung 1TB F3 Spinpoint
- Coolermaster HAF 922

Thanks for all of your replys.
Quick update: Got in tonight and thought I would have one quick look at it. The first thing I did was unplugged one of the RAM modules from the slots and... IT LIVES!!! Just about to install Win 7 and will see how that goes. Thanks again.

Update 2: Win 7 installed fine, no problems. Very quick install. Still cant get over how quick the i7 is on default clock speed, OC'ing it will turn it into a beast!

Had the "no signal" problem myself, fixed it by clearing the jumper.

Yea I also tried this in the process of illumination. Not that I mattered lol.
