It's a pretty long story, so appreciate anyone who reads it all and any input/solutions are a godsend, let's start with my specs.

Processor: Intel Core i5-4670K Quad-Core 3.4 GHZ
Motherboard: Asus Z87-A ATX
Video Card: ASUS GTX760-DC2OC-2GD5 2GB 256-bit
RAM: G.SKILL Ripjaws X Series 16GB (2 x 8GB) DDR3 F3-1866C9D-16GXM
SSD: Samsung Electronics 840 Pro Series 128 gb
HDD: Western Digital Caviar Green 3 TB SATA III
Liquid CPU Cooler: Corsair Hydro Series H55 Quiet Edition
PSU: Corsair CX600M 80 PLUS Bronze
Case Fans:
BitFenix Spectre 14025B 140mm
NZXT 140mm
NZXT 120mm x2

And if it helps, Case: NZXT Phantom 410 (Gunmetal/Black)

So basically I built the rig, plugged my existing monitor in on the onboard vga and ran it. First error was the cpu fan not found, which wasn't a problem as I plugged the fan to the fan controller provided by the case. I booted from a USB containing a copy of Windows 8 Professional Edition that I created earlier, and began installing on new partition on the SSD. I believe it restarted after the installation was complete as I saw the screen go blank when I came back from a short break.

Then it never came back, but everything seems to be running properly, just no signal for the display. So I tried to connect to a HDMI display on the graphics card, thinking that maybe the default display has changed due to windows being booted. It didn't work so I tried restarting a few times observing if anything was wrong, until I decided to remove the GTX 760 and try the onboard vga and it worked. I was able to boot into windows and use it like a normal pc, so I assumed it was the GTX that is the problem, but I do wonder why it was fine before I started installing Windows.

Next, I tried to setup a second monitor since my old setup was dual monitor, but the onboard HDMI didn't work either, no signal. This then spark me to try all the displays available onboard and also with the GTX attached. Result was that onboard VGA works without the GTX, onboard HDMI, MiniDisplay and DVI do not work. With the GTX, the two DVI and the HDMI on the graphics card don't work and I do not have any monitor/adapter/convertor to test the DisplayPort, and all onboard displays do not work either.

Got me thinking if it really is just a faulty graphics card, or is it the motherboard that is faulty. I did some searching and some suggested removing one of the RAM sticks to fix this, didn't work. Some said that the power supply was insufficient, but I actually went to websites like Pcpartpicker to check the wattage needed to run my rig, it should not take more than 400w. Nonetheless, I tried to provide more power to the graphics card and motherboard by unplugging my fans and storage, just to see if the displays would work if there is more power available, but it didn't help. I do not have a PSU of higher wattage to test, and similarly, I don't have other machines that could support the graphics card for me to test it.

I urgently need the rig to run properly as I bought it to work on a project and the deadline draws near while I could not even start due to this issue. I really hope there is a fix for this as it will take weeks if I were to send any of the parts back.

To narrow it down further, I tried the graphics card on other PCI Express slots, tried resetting the CMOS by removing the battery, switching the pins of the jumper and holding the power button, tried installing all the latest drivers and flash the latest BIOS, tried changing the primary display to PCIe. Nothing worked and I have not a clue to how to fix this, and the greatest mystery is what actually happened after windows 8 was installed and caused the GTX to prevent the onboard vga from working.

I hope it's just a wrong setting in the BIOS or somewhere and not a hardware failure. Please help guys, thanks everyone!

Take both mem sticks out, then reseat them firmly, here the clicks. Also double check that they are in their proper slots. Remember to ground yourself first, touch something metal to discharge static. Let us know and we'll go from there. One question do you get any beeps? Or it comes on like it's fine and just a black screen? Good luck, thanks...

Sounds like a bad card to be honest. You did everything that I would of done and the only thing not working is the card.. So I'm guessing you got a bad one since you said that everything else works just fine with the onboard GPU.

Remember I told you that I tried removing one of the mem sticks to see if it will work? Well, turns out that the culprit was the other mem stick which I left untouched. I took them both out and re-attached them, then everything just worked. Thanks a bunch!
