Do you have the power plugged in for the graphics card?
Re-seat the card.
Is the computer locked up when you boot up? Press the Num Lock or Caps Lock to see if your keyboard is responding.
Double check your DVI connections?

Switch DVI cables? I've had cables go bad before (it's pretty rare though)
Try a different video card.
Try the other PCI-E slot.

The ASUS P6T......what slots did you use for your ram? Black or Orange. The Orange slots need to be populated first. If you have it on the Black slots, it won't boot.

Yup, step #8 on the checklist. :)

All 3 RAM modules are in the orange slots, and its the Kingston HyperX 6GB (3 x 2GB) KHX2000C9D3T1FK3/6GX kit. The PSU I have is a Arctic Power 700w.

You still haven't mentioned whether you have performed every step in the checklist linked above.

Have you tried booting with a single stick of RAM installed? Do you have the main 24-pin motherboard power connector, 8-pin CPU power connector, and both PCI-E power connectors firmly plugged in?

Yea I've tried with one and two sticks of ram. Also yes the 24-pins are in the motherboard. All pins are correctly in Graphics card. :S

There's more than just a 24-pin motherboard power connector that needs to be plugged into the motherboard. There's also an 8-pin CPU power connector located near the CPU socket. There's probably a cover over four of the pins.

I have found out that the CPU isnt plugged in, I feel like a moron now lol, yes there is 4 covered up, do I take the 4 pin blocker off to make it an 8 pin power socket?

8 pin is better than 4 pin, but it will run on 4 pin power. If you have an 8 pin on your PSU, use the 8 pin. Make sure it's not the PCI-E 8 pin, but the eps 8-pin.

I have plugged in the PCU plug but it only has 6 pins rather than 8, there is a 8 pin plug but it doesnt fit in as some of the pins are joined together and are different shapes to the plug, will this work?

CPU i meant not PCU*

No, do not use a 6-pin plug. It's meant for the graphics card. If you don't have an 8-pin plug on the PSU, just use a 4-pin plug.
October 27, 2009 7:04:42 PM

That might be the PCI-E 8pin.
The 6 pin is also for PCI-E.
What Power Supply do you have?
October 27, 2009 7:07:30 PM

Ok, but i only have one 4 pin connector which is going into the main motherboard power socket making it a 24 pin connector, what do I do?

That's the wrong one then. Please post your PSU model so I can google it.
October 27, 2009 7:21:36 PM

I have now found the 4 pin after unwiring everything so hopefully it will work now
October 27, 2009 7:32:47 PM

Great, let us know if it works
October 27, 2009 7:57:29 PM

Ive sorted out the 4 pin connection, and now there is a signal being sent to the screen but not one i want, it says "You have not connected one of your video card power connectors to the power supply, please refer to the "getting started guide" for proper hardware instillation". What I am not sure of is if the Graphics card needs both 6 and 8 pin connectors in or if it needs one of them?

Both PCI-E power connectors are required. The GPU owners manual would have told you that.
October 27, 2009 8:29:54 PM

The guide that came with it was rubbish, it was just a generic one which applies to all graphics cards. Ive put two power inputs into it but when I connect it all up im left with one thing left. As it is at the moment ive got a 6 pin connecter going to molex, then a 8 pin connector going to two female plugs, and in one of the female plugs ive got a male to two molex connector on it, that leaves one female plug un-used

So, did you get it working or not?
I'm completly lost. Please post picture of how you got i wired up.
What is the model of that power supply?
