Question Strange problem with video card and new motherboard

Hi folks,

I'm facing some issues with my motherboard replacement.

I have replaced one ASUS H81M-CS/BR (faulty) with a TGT TG-H81-G355-U/P (same socket, LGA 1150).

But my video card (one Geforce 450 GTS w/ 2GB GDDR5) does not work on PCI-E 16X SLOT. When I use that card on a riser card on PCI-E 1X works fine.

I have tested the same slot (PCI-E 16x) with a Radeon HD 6570 and works fine.

Has anyone come across something like that? Any suggestions?

Thanks

Hi,
I'm having the exact same problem with a GTX460 and a Intel DH67BL. I've opened a thread here:

Is there an option in the bios to set to legacy mode which an old GTX460 requires?
The only option that I have is UEFI Boot Enable or disabled. Its on Disable. When it enabled my windows boots into the Windows Setup. When disabled it boots normally

There you go, you have your answer.
GTX460 is a legacy mode device; It may have difficulties being recognized on a uefi only motherboard.
I'm sorry, I think I wasn't clear. It boots but using the integrated graphics. It still doesn't recognize my GTX 460.
