Geforce 770 not recognised in Dell xps 8500

[Mikkelmand]

A few days ago I got my colleagues old computer (Dell xps 8500 prebuilt) for free .

specwise is it much better than mine, the only thing that sucked on the Dell was the graphics card

But it doesn't recognize the my  770 in the bios or the device manager and I just get a black screen 

 

I already tried switching it back to my old rig where It worked fine.  all drivers and windows are up to date 

 

Anyone have any idea what this could be about?

Try updating the BIOS, you may need a BIOS update to properly support UEFI graphics cards.

Do the fans on the 770 spin when you turn the pc on?

[Mikkelmand]

yes, they spin at idle rate

I had a dell xps 8200 and buying a gpu for it was hard. I found out through trail and error that Geforce gtx 750 ti and geforce gtx 960 worked great but these where they only cards I found that worked.

Sounds like a power issue.
