Hi,

I'm trying to install an AMD Radeon R265 video card in a Dell Vostro 260. I have swapped both this card and the 500 watt power supply from another PC, 

When installed the PC does not output video from either the onboard graphics or the Radeon video card.

I have the latest A10 BIOS but there is no option to disable the onboard graphics.

I have seen lots of other threads on this issue but no solutions!
