GTX 770 with Z87-Pro won't boot

[Shirogane]

When I turn my PC, and pin my HDMI cable into the graphic card, nothing appears. When I try the same with integrated card in CPU, it is all fine, but till Windows dont see my Nvidia crd. Bios on the other hand shows in System Agent Configuration: in NB PCIe Configuration PCIEX16_1 Link Speed x0 (with auto setup).

What can be the problem? Can it be that the graphic card is damaged or motherboard?

Maybe card is incorrectly put in? (is it possible, eventho it iws somehow shown in bios?) i believe it looks quite "odd inserted" ( i didnt insert it though, I ordered the PC).

My PC is:
i7-4770k 3,5Ghz
Asus Z87-Pro
Gigabyte GTX 770 4GB

Have both the 8 pin and 6 pin cables connected ?

Used the screen's OSD to select proper input ?

MoBo LED's indicate anything faulty ?

Card may have shaken loose while shipping

1. Yes
2. What the heck is that
3. Similar to 2nd
4. I unlockd it and locked back. ANd it is shown in BIOS.


From what i've read on the forums, here, NVIDIA and few others. A lot of peps has similar probs with Z87 and PCIe cards (especially graphic)
