Hi,
so I've gone and built myself a PC for the first time,and everything seems to be fine other than my graphics card ( Gigabyte Radeon HD 7870 OC ). When I boot up the PC without the graphics card plugged in to the PCI slot, and with the DVI cable plugged in to the motherboard ( Gigabyte Z77-D3H ) it works absolutely perfectly, after the post beep, everything comes up on the monitor. With the graphics card plugged in properly, however, I get no POST beep and nothing comes onto the monitor, but the fans do spin.
Someone help me please

Is the power cable for the CPU plugged in?

Did you connect the 6-pin PCI Express power connector ?
If you did`t connect it and there you go !

I have connected the CPU power connector, however I get the feeling that I've connected the GPU incorrectly. There appears to be two slots for 4 pin PCI Express power connectors , and I have two 4 pin PCI Express power connectors plugged in. Should i take one of the power connectors out and convert the other one to a 6 pin power connector? I'll try to post a pic of what I mean.

Ignore the last two posts. I've taken out one of the two 6 pin PCI Express connectors, and I now get a POST beep when I boot up the computer. However, I am still not getting a display signal. I do get a display signal when I am plugged in to my motherboard DVI, but none when connected to the GPU DVI. Any more help?

If you have 2 conectors on you GPU card you MUST connect them both.
And you must be OK.

Only reason i can guess now is that you mobo is sett to Boot not from PCIE but for Integrated GPU
Try to change that in the BIOS
And yes pls use this guide - http://www.tomshardware.com/forum/261145-31-perform-ste...
Something strange is happening with you PC ...

I've used all the steps in the guide, It's not that. When my GPU is properly plugged in, I just don't get a POST Beep. The computer works perfectly when booting up without the GPU and putting the DVI into the Mobo. I've tried installing the drivers for the graphics card, and that hasn't made a difference, I've also tried turning off the integrated graphics on the motherboard but when I do that nothing happens, and when I try putting the DVI back in to the motherboard I get one long beep followed by two short ones, and i subsequently have to reset the
BIOS. I'm starting to think that the graphics card is the problem, the only other thing I could imagine being the problem is the PCIE slot on the motherboard, but I physically can't fit the graphics card in the other PCIE slot because the graphics card is massive.

Is it the modular one? If so it should have come with two sets of 6+2 and 6-pin. Have you tried the other set? How about in the other rail?

It is the modular one. I've also tried that but to no avail :(

Then you either have a video card that is DOA or a power supply that is not putting out it's rated value. If you have the ability/access to another supply then try that otherwise I would return/replace the video card.
