So, I decided to pretty much build my sister a pc (because she asked me to) and so first it was the psu, case, gpu, and now the mobo and cpu. I had a B85 that wouldn't work without a BIOS update that i mistakenly bought (returned), and now I have an ASRock H97 Anniversary, with that i5 4590. So i get everything fitted up and plugged in (This is my third time building a pc) and hit the power button, and it turns on, runs through BIOS, then finally "starting windows"...(Windows 7) the 3 colored lights appear and start to move then blue screen flashes and goes to repair tool. "Windows failed to start" I need advice on either what i did wrong or how to diagnose what i did wrong, i need to fix it asap.
