I just got my new asrock z97x killer mobo and my i7-4790k. Hooked everything up for a build for my gf and just get a blinking cursor on a black screen after mobo splash. Checked and updated BIOS have 4 different HDDs I have tried 2 new 1 Windows 10 1 Windows 7 and just get the cursor. Made a USB boot stick for Windows 7 and it does the same thing tried 2 different DVD drives for win7 install disc and get the same screen. In the BIOS it recognizes everything I connect to it. Just will not go past that damned flashing cursor. I am currently using the exact same build with my computer and everything works flawless. Bootndisc and USB work tried on other PCs. At this point I have tried swapping the CPU and get the same thing so I'm thinking mobo is faulty. But I am lost and not sure if I should return mobo or if there are any fixes. Please help.
