Did the guys at the store you took it too get it to fire up using your motherboard and your CPU together in combo or did they test each component separately with other components they had? I still think you need to take your board, CPU and RAM together to them and get them to test it that way. There certainly could be a compatibility issue with the RAM and that combo of board and CPU. It's not common but it does happen.
I do..I think it's the ram...it may be listed but it is some suspicious stuff?....You need to buy a cl16 G.skill kit or like the Corsair LPX kit...and if it still don't boot then yeah...mobo or cpu....That would rule that out for sure.
