Dear community,

here's my problem, I'have built a new conf :

i5-4670k
ASUS Z97i-plus (itx, 1 PCI 16X port)
Silverstone 650W Gold
Nvidia gtx780 Zotac Amp

To make the card fit in to my case I used a 16x male - 16x female PCI riser.

When the riser is plugged-in the pc won't post, black screen. Otherwise i can use the pc normally (thx to the GPU chip in intel proc).

I tried to flash the latest bios,

set the PCI to gen 1 or 2 or 3 without success.

I ordered a powered-riser, to see if it's a power problem. For what i googled it seems that a power riser it's needed only with 4 or more video cards, so i really don't know if it will solve my problem.

Please if you have any advice, every kind of help is appreciated.

Thank you.
