H61MV-ITX cant see ATI GPU

Any time you add or change a piece of hardware like a video card, you should clear the UEFI/BIOS before you start the PC with the new video card. Did you try that with the ATI video card?

Question for you, what video driver did you have installed when you tried to use the ATI card? You mentioned two different Nvidia based video cards, whose driver is not compatible with the ATI card. Did you uninstall the Nvidia video card driver before trying to use the ATI video card?

Were the other two PCs you tested the R7 275 on that worked with it, significantly newer than your H61 board?

ASRock had a large number of H61 mother board models, and most of the ones I checked did not have many if any UEFI/BIOS updates. Your board has downloads for Windows 10, so I would think an R7 275 video card, which is not a just released card, would work in your board.
