I have a system with a Gigabyte GA-A55m-DS2 motherboard with and AMD A6-3670 processor. I am currently using the AMD Dual Graphics feature with a Radeon HD 6570 PCIe graphics card.
I decided that I wanted to boost my graphics bought a Radeon R7 260X video card. When the card arrived, I removed the old card and installed the new one. When I did this, the system would only recognize video coming from the onboard ports. If I disable the onboard graphics, the system does not boot and won't complete POST (I get a BIOS error beep of 1 long and 3 short beeps. Research shows this to be a video card not detected error)
I contacted the manufacturer and they said to RMA it. Which I did. I ordered a new card (from a different manufacturer, but with the same chipset). When it arrived, I went through the same process and got the same result. The system will not detect that the card exists.
I have checked the power supply requirements (to the best of my ability) and it says that it should handle the load. I have an Ultra 550W power supply with the appropriate 6pin PCI-E connecters, they are seated firmly on the card
I'm really unsure what to do at this point. I've had this motherboard for over a year and the Radeon 6570 worked perfectly during that time. I have a hard time believing I got TWO bad R7 260X cards in a row (Especially from different manufacturers) so I'm under the impression that it's an issue with my motherboard. Has anybody use this particular part combo before? Should I consider purchasing a new motherboard or a new power supply to solve this issue?
Any help is appreciated.
