PC won't boot with graphics card in the top PCI-E slot, but will in the bottom slot. Broken motherboard?

Hi all,

I have just assembled my new PC with the following setup:

Intel i5 4670k
ASUS Z87-C
Gigabyte HD7870
8GB Kingston HyperX RAM
120GB Kingston HyperX SSD
1TB WD Blue HDD
LG DVDRW
Thermaltake LitePower 600w Black Edition PSU
Windows 8.1

The PC will not boot when I place the graphics card in the top PCI-E slot. I get both the VGA LED and BOOT LED showing red and nothing happens. There is power to the GPU, as the fans are spinning. However, if I put the graphics card in the 2nd (bottom) PCI-E slot, the system boots fine.

I am concerned because the top slot is PCI-E 3.0 and the bottom is PCI-E 2.0 (both are x16 though), so this means the speed will not be as good? Also, I just bought it all and am wondering whether to return the motherboard back to the shop.

Any help you can offer would be much appreciated. I have spent 2 days trawling the web for answers but have not found a solution.

Thank you!

If the card works in the lower slot then I would return the board.

Please RMA it ASAP.

I've added the "ASUS" tag to ur post as well so that any ASUS representative can find this post and advice the matter if they are around.

Try testing the board outside the case for ruling out a shortage.
If still the same, remove the CPU and check the socket for bent pins.

try resetting the bios with the power removed, if the problem still persists then you should take the board back
