Try taking out the CMOS Battery and also make sure that the RAM you have are installed in the correct slots, especially if not all of the slots are being used. Also, try the paperclip test for your PSU to check if the PSU is even functioning correctly. It sounds like the PSU may be giving you trouble as that is common for PSU's that are bad or about to go out. What are the specs of the PC? Make sure the PSU can even handle the PC you have and a weak PSU will not even boot the PC up since it may not provide enough watts and AMPS for the GPU. Make sure your PSU has the correct AMPS needed for the card to perform, many people overlook this critical piece of info when buying PSU's.

Did you do the paperclip test? You should also get a Voltage meter to test the PSU if it's even pushing the correct AMPS and such, it could be that the PSU is faulty or got damaged during shipping.
Also, check all wires, connections on the mobo to see if any got loose or such. Check the PWR pin/plug (that is the pin/plug used to power on the PC when you press the button). Hopefully it's that that came loose, simply plug it in and then press the button to turn on the PC.
So far, it sounds like the PSU is bad or if the PSU is working fine after doing the paperclip test w/voltage meter, then it may be the motherboard that is bad and may need to be RMA'ed/
If you don't know how to take apart the PC because in order to do the paperclip test and voltage meter reading, you will have to unplug the PSU from all PC components and then do the paperclip test on the motherboard connector on the PSU along with the voltage meter readings. If you do not know how to take apart your PC, then your only choice is to have a pro technician take a look at it. Try calling the manufacture/place of purchase (call customer service line) and explain your situation. Depending where you bought it, they may send a tech to your home to take a look at it, or you will have to take it to a PC repair shop as they will have to take your PC apart to test the PSU and such.
Sadly, that's all I can offer.
Also, one last thing, you can try taking out the CMOS battery for 30 seconds and then putting it back in to reset the BIOS, that helps at times whe a PC is being stubborn.
I feel you man, I've had faulty hardware arrive too. Try asking a friend to bring his gaming PC over and test your parts on his PC, especially the PSU and GPU. But that would require your friend to know how to take apart a PC and assemble them correctly and such. While you are waiting to take your PC for service, it's a good idea to learn how to build and maintain your PC, it's easy to learn after a few hours of reading and such.
