What is the brand, model name or series (not serial) number including any revision number (rev 1.0 for example).
If the MB has an integrated video chip try removing the add on video card and using the integrated video, if no integrated video chip try removing the add on card and powering up, if no change reseat the add on card and remove all but one stick of Ram, again try powering up, if still no change try swapping Ram sticks until all sticks and Dimm slots have been tried.
Good luck, let us know how you get or if you require further assistance.

You will then need to short out the 2 power on pins on the MB header to get the PSU to activate, you can use a small flat bladed screwdriver or a paper clip bent into a U shape, this is perfectly safe if you do not touch anything else, the idea is to see if we can get a BIOS screen if you do you can then add one component at a time until you find the problem component, you must power down and remove the power cord from the wall before adding a component, second suggestion try a known working PSU, it is not unknown for new components to be bad, third suggestion try and loan an ordinary PCI graphics card (not pci-e) again to try and get a BIOS screen and check for stray screws or bared wires in case there is a short circuit.
NB: I couldn`t find any information on you MB so if you do the barebones set-up check if there is a power switch on the MB and shorting the 2 pins to activate the PSU may not necessary.

And sorry I was a little busy and wrote down the wrong model number. It is the DFI lanparty dk 790fx.

Yes + make sure that the CPU fan is connected to the header on the MB.
Am i supposed to be leaving the CPU and CPU fan cooler in as well?

You will not get any type of display with the CPU removed, be sure to reapply fresh TIM before you reseat the processor, see the tutorial courtesy of Digerati @ http://www.geekstogo...rface-material/
left everything else the same and took the CPU out and the PSU came on giving power to the video card but i did not get to the BIOS
Possibly the 12V ATX socket on the MB, this is what powers the CPU, these can be either 4 or 8 pin connections and the wires yellow and black, inspect the MB socket and when you reassemble the components ensure this is securely in place.
So I'm thinking this is either the MOBO or CPU?

EDIT: ALAS! Switched a stick of RAM and got to POST. Going to try this stick of RAM with New video card.

It is near midnight here in the UK so I am going off line (work at 7am) good luck with the testing and I will check back tomorrow, others may assist you meanwhile if you need post a reply in between now and then.

That is why it is suggested that you only add one component at a time until you either A: Find a problem component and replace it B: Are able to connect all components successfully meaning that you could have a short in the case/MB or a bad power switch.
I connected my peripherals and tried to start it. I got the Beep code error for video
