Newly Built PC stuck in bootloops.

[TheKindlyMan]

Hey guys, I've built about 4 PCs in the past, and me and my friend were building a new one recently, but we're running into a dead end. We've put everything together and upon powering the system this is the chain of events on the ASUS motherboard:

Everything lights up, fans start up.

Memory / "MEMOK!" light passes, CPU passes, VGA light passes.

Upon getting to the PCIe x16 3.0 light the system crashes instantly.

System automatically reboots and powers through all the lights and this time passes the PCIe light and hits the Boot Device light and idles there.

At this point an image can be seen on the screen of the ASUS logo and instructions to hit del or f2 to enter BIOS. But it does not respond to any key commands.

I had read that the board itself has issues with the original memory we had on this machine (8GB of Mushkin Redline) so we went with the manufacturer approved memory 8GB of GSkill Sniper memory. However the issue persists.

Here's the build:

Motherboard:

ASUS Z87-A

VGA:

XFX Double D FX-787A-CDFC Radeon HD 7870 GHz Edition

CPU:

Intel Core i5-4670K Haswell

SSD:

SAMSUNG 840 Pro 128 GB

PSU:

Corsair HX750 750W

RAM:

G.SKILL Sniper Series 8GB (2 x 4GB)

Do you have a different GPU card you can try? Is there a good power cable to the GPU?, is the card fully seated in the proper slot?
