I have a Gigabyte H81M-S motherboard with core i5. I had a 4gb 1600 Mhz kingston hyper-x blue ram already installed on it. Then I added another kingston 4gb 1800 Mhz hyper-x fury ram to it. On first boot after installing the 2nd ram everything was working perfectly. But on the next day when I swithed on the pc it wouldnt turn on, it didnt even reach the bios stage. So I tried each ram individually and the pc works fine on the hyper-x blue ram but fails to start on the hyper-x fury ram. And the final curve ball is that the hyper-x fury ram works fine on other computers. Is it a motherboard issue, or different rams issue I dont know. Please help!!
