A while back, I ordered parts for my first time PC build. Pertinent parts are:
SeaSonic S12II 430B 430W ATX12V V2.3/EPS12V 80 PLUS BRONZE Certified Active PFC Power Supply

ASRock A55 PRO3 FM1 AMD A55 (Hudson D2) SATA 6Gb/s USB 3.0 HDMI ATX AMD Motherboard

AMD A6-3650 Llano 2.6GHz Socket FM1 100W Quad-Core Desktop APU (CPU + GPU) with DirectX 11 Graphic AMD Radeon HD 6530D AD3650WNGXBOX

G.SKILL Value Series 8GB (2 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9D-8GBNT

I assembled everything above outside the case and attempted to power up. The CPU fan would spin until I cut power from the power supply, but I wouldn't get any POST beeps from the speaker nor would anything display on the monitor. So based on some research and advice, I RMA's the motherboard as it seemed DOA to me. I received a second motherboard, assembled, and it did the same thing, only the CPU fan spins and nothing else. Previously, I tried switching the RAM sticks and removing one and both of them, but the same result occurred. So I don't think the RAM is causing the problem.
In further research, I found someone that had a similar issue and it turned out that their CPU wasn't compatible with the BIOS on the motherboard. So I pulled up the motherboard's page on ASRock's site and checked the CPU Support List at http://www.asrock.com/mb/overview.us.asp?cat=CPU&Model=A55%20Pro3. I'm not seeing the CPU model number I have there so does that mean it isn't compatible? It seems like a really small list to me so I wasn't sure if maybe that list represented “families” of CPU's or something, but it seems like I screwed up and bought an incompatible mobo and CPU. Originally, I used pcpartspicker.com and it noted compatibility there, but I suppose it isn't foolproof since that site deals with multiple mobo's and CPU's. If incompatibility is the case, I can't send the CPU back, however I may still have time to send the mobo back and buy another. Anyone have any advice on a good, similar motherboard that will work with that CPU?
